Kabocha croquettes (korokke) is our family’s fall favorite. Crispy on the outside and naturally sweet and savory on the inside, it’s like a party in your mouth! These croquettes will disappear in no time.
When the autumn rolls in and all kinds of pumpkins and squash start to pile up in the front of the grocery store, I grab my favorite of all, Kabocha, and make these Kabocha Croquettes. In Japan, we call this Kabocha Korokke (かぼちゃコロッケ).
What are Kabocha Croquettes?
They are simply croquettes made with kabocha instead of the more common filling of potatoes. They are one of my favorite fall dishes to make. The outside of the panko-crusted croquettes is crispy, while the soft mashed kabocha inside is sweet and tender. These croquettes have just the right balance of savory and sweet.
Kabocha (かぼちゃ, 南瓜) is a type of squash and here in North America, it’s also called kabocha squash. I am not sure why, but in Japan, it is known as “pumpkin” instead of squash. I learned that it’s called kabocha pumpkin in Australia (am I right?).
Kabocha is notorious for its really tough green skin. When you cut the green kabocha squash in half, it’s almost a surprise the incongruity of the bright orangey flesh.
Kabocha is naturally sweet, much sweeter than butternut squash or sweet potatoes. If you like making sweets, don’t miss my Kabocha Pie – it’s a good twist on regular pumpkin pie.
5 Tips to Make the Best Kabocha Croquettes
This recipe is so simple (did you see the recipe?), and that’s why each ingredient plays an important role. Ingredients need to be fresh and high quality, so the dish comes out wonderfully, along with a little bit of love from your cooking.
1. Use the butter
I’ve tried both olive oil and butter to saute onion, and I have to say using butter is a game-changer. It’s such a subtle thing, yet you’ll notice the difference at the end. Trust me on this.
2. Use bacon
So I have tried different types of meat in these kabocha croquettes, and my family’s favorite turned out to be bacon. If you are familiar with kabocha recipes on Just One Cookbook, yes, I did add bacon to the Kabocha Salad too! The flavor and texture of bacon go well with mashed kabocha – much better than ground meat.
3. Keep an eye on the moisture
You can steam the kabocha as I did, or use the microwave or boiling method. But the key is to make sure the kabocha is not wet when you are about to mash it. If you see too much moisture, you may want to put the cooked kabocha in the pot and let it evaporate on low heat. The sautéed onion and bacon in butter has plenty of fat and moisture to form the kabocha into a ball shape later on. Some onions also have more moisture content. If it does, try to evaporate it before mixing it with mashed kabocha.
4. Deep fry at 340 ºF (170 ºC)
Remember, kabocha is already cooked. That means all you need to do is to fry the croquettes until they are golden brown. Insert your long cooking chopsticks and see if there are small bubbles around them. Once you see the bubbles, put a few croquettes in the oil. Don’t put too many croquettes at once as the oil temperature will go down as soon as you put croquettes in the oil. Turn once or twice until they are golden brown.
5. Add salt at the end
You might eat these kabocha croquettes with tonkatsu sauce as most panko-crusted deep-fried foods are served with tonkatsu sauce in Japan. Personally, I don’t think it’s a good match. Instead, sprinkle some good salt AFTER deep frying. It can be good quality sea salt or Himalayan pink salt. It brings out the kabocha flavor to the max!
Make Kabocha Croquettes into Vegetarian
To have extra oomph, I added some bacon pieces; however, you can easily make your kabocha croquettes into a vegetarian dish by skipping the bacon – easy as that!
Bake or Deep Fry?
Last but not least, I know you’ll probably ask me if you can bake this dish instead of deep-frying, so let me answer first. Either works. Many people prefer not to deep fry at home (and I hear you – all that smell, mess, and oil), so try baking them instead. Use my pre-toasting panko technique found in Baked Croquette, Baked Tonkatsu, Baked Chicken Katsu, etc.
However…(you knew I’d say this?) there is nothing like biting into freshly deep-fried croquettes. I am a self-proclaimed croquette connoisseur, and I have to tell you the deep-fried version will always win. So if you feel okay about deep frying, definitely take this deep fry path!

Kabocha Croquettes
Ingredients
- 1½ lb kabocha squash (½ kabocha with seeds)
- 3 slices bacon
- ½ onion (3 oz, 85 g)
- ½ Tbsp unsalted butter
- ½ tsp Diamond Crystal kosher salt
- ⅛ tsp freshly ground black pepper
- 3 cups neutral oil
For the Breading
- ¼ cup all-purpose flour (plain flour)
- 1 large egg (50 g each w/o shell) (beaten)
- ½ cup panko (Japanese breadcrumbs)
Instructions
- Gather all the ingredients.
- Remove seeds and pith from 1½ lb kabocha squash and cut into big chunks, about 2-inch (5-cm) pieces.
- Set up the steamer (I use this steamer basket inside the Dutch oven here). Steam the kabocha for 20 minutes or until tender (enough that you can mash with fork) but don’t overcook.
- While steaming the kabocha, mince ½ onion. Slice parallel to the grain, slice against the grain (image 1), cut into cubes (image 2), and chop into even smaller pieces (image 3).
- Cut 3 slices bacon into small bits. For better texture, I like the bacon to be about ¼ inch (6 mm).
- Heat ½ Tbsp unsalted butter in a large frying pan over medium heat. Add the onion and sauté for 2–3 minutes, and add the bacon. Cook until the onion is translucent, tender, and nicely brown. Set aside until the kabocha is done steaming.
- Remove the kabocha from the pot and let cool until you can touch (but still warm). Remove the skin using a knife or spoon. Kabocha skin is edible and you don’t have to remove it. However, your kabocha croquette will be dark in color instead of a bright orange color.
- Transfer all the kabocha in a large bowl and mash with a fork.
- Add the onion and bacon mixture to the mashed kabocha. Try to avoid adding excess oil, which could make the mixture too wet. Season with ½ tsp Diamond Crystal kosher salt and ⅛ tsp freshly ground black pepper.
- Combine well together. Using a cookie scoop, make it into ball shape. I can usually make 15–18 balls with ½ kabocha (1½ lbs with seeds).
- Cover with plastic wrap and refrigerate for 15 minutes to kabocha balls become firmer.
- Add 1 Tbsp water to 1 large egg (50 g each w/o shell) (beaten). Coat kabocha balls in ¼ cup all-purpose flour (plain flour).
- Then coat with the egg mixture, and finally ½ cup panko (Japanese breadcrumbs).
- Cover with plastic wrap and rest in the refrigerator for 30 minutes. During this time, the flour absorbs moisture. As a result, it’ll splatter less in the oil and the batter becomes stickier and won’t come off while deep-frying. Also, if you deep-fry the food when it's still warm, the steam inside the filling will get hot and try to escape, which will end up exploding in the hot oil.
- When it’s almost 30 minutes, start heating up 3 cups neutral oil to 340ºF (170ºC) in a pot. Insert the long chopsticks, and when you see small bubbles appear around them, it’s ready to deep fry the croquette. The filling of the croquette is cooked already, so all you need is to fry the coating until golden brown.
- Transfer golden kabocha croquette to a wire rack or a plate lined with paper towel. Sprinkle some salt such as sea salt or Himalayan pink salt.
To Store
- Once it’s cooled completely, you can put the leftovers in an airtight container and store in the refrigerator for 3 days and in the freezer for up to a month.
These are fantastic! Usually eat them on their own with dipping sauce, but what would you recommend for pairing it with a meal?
Hello, Gigi, Thank you so much for taking the time to read Nami’s post and try her recipe!
This Korokke may be served as a main course or paired with an easy-to-prepare meal such as Honey Soy Chicken, Teba Shio, or Sabashio, to make preparation easier.
Any salad or green dish, together with miso soup and rice, would make an excellent meal.

I’ve made this recipe twice now, and it came out great both times! The filling is so creamy and savory and delicious.
I didn’t make any changes to the recipe, but a couple of notes in case they’re helpful for others:
– The first time I made this, even though I didn’t use the skin itself, I used the green/brown flesh close to the skin, and the korokke turned out pretty dark. This time, I was more careful to leave out the green parts (I did eat them separately!) and the korokke were a prettier orange color
– I burned the onions the first time and came close to doing it again this time, although I managed to catch it. My bacon was thick, so it was difficult to get it fully browned without the onions getting brown. Next time I think I’ll take the onions out while I brown the bacon and add them back in at the end so I don’t have to worry about it
– Even though I refrigerated my mixture before forming balls, they still did not hold their shape like the picture when I first scooped them out. But once I dropped them into the flour, it was quite easy to get them into nice spheres
Thank you Nami-san for this recipe! I don’t make things with this many steps very often, but this is totally worth it. It’s my favorite recipe for fall parties.
Hi, lineetta! Thank you very much for trying Nami’s recipe and sharing your cooking experience in detail!
We are sure this will be very helpful for many readers. 😊
Thank you for your love and support!
Based on the ingredients and that it’s deep fried, I assumed I’d have a decent korokke , but these… wow, far better than I even anticipated. The tiny crunch of onion, the flavor of bacon and the creamy pumpkin were in perfect ratio. I didn’t even need to salt them at the end or whip up a dipping sauce. And even though they lost their beautiful crunch once they went room-temp in my bento, it served to emphasize the softness and flavors of the inside, like a pumpkin salad in its own little packet (or like a creamy potato salad).
Hi Home Cook! We are glad to hear you enjoyed Nami’s Kabocha Croquettes recipe!
Thank you very much for trying her recipe and sharing your cooking experience. Happy Cooking!
My kids love these. I substitute the bacon for ground pork and onion that I sauté in bacon fat that I keep in the freezer. It gives the korroke a more consistent texture. A plate of these, some bulldog sauce and Superstore on the tv is our happy place.
Hi C Sich! Awesome! We are so happy to hear your kids enjoyed Kabocha Croquette!
Thank you very much for trying Nami’s recipe and for your kind feedback.☺️
Thank you!! I had leftover roasted kabocha and used that. It was a bit dry but still good! I made half with cheese instead of bacon (for pescatarian kid) and was surprised I actually liked it! The Japanese market sometimes carries Kabocha Korroke but it’s great to try making it myself and better fresh (& with bacon)! Thank you!
Hi Lynn! Thank you for your kind feedback! 🙂
We are happy to hear you enjoyed homemade Kabocha Korokke!
Thank you very much for reading Nami’s post and trying her recipe! 💞
If i freeze them, can i fry them immediately for when i need them?
Hi Eric! Thank you for trying Nami’s recipe!
For better quality taste, We recommend frying them first and freeze them.
The home freezer often takes a long time to freeze, and during that time, water in ingredients may release.
To reheat them, Bake at 350 ºF (180 ºC) for 10-15 minutes for defrosted ones or about 35 minutes for frozen ones. (Please check if the inside is warm before serving.)
We hope that helps!
Yum! We tried these last night, without the bacon & deep fried, and they were delicious!
I had a thought that next time I might try sneaking a little goat cheese into the kabocha balls..
Hi Lisa! Thank you very much for trying this recipe and sharing your cooking experience with us!
The cheese inside the Kabocha Korokke sounds delicious and yummy!🙂
Good idea on the goat cheese! I’m going to try that.
Can you airfry these?
Hi Nikki,
We have never tried it, but other readers said it worked. Please let us know how it goes!🙂
I have cooked this savoury recipe using butter instead of olive oil in accordance to your recommendation and I have run the kabocha in the oven as a substitute of boiling it. I think this method increases its flavour.
It is true that you have to take care with the moisture but it is not a big problem.
I have too, kept the croquettes on the fridge for a while before frying them for getting a crispier result. Could be?
My wife and me have enjoyed this marvelous recipe.
Many thanks to you!!
With love from Spain.
Amaro
Hi Amaro!
Yes! Baking the Kabocha will help reduce the moisture and also enhance the flavor of this dish. Great choice!
Thank you very much for trying this recipe and for sharing your cooking experience and tips with us!
Is it possible to fry it in an air fryer instead of oil?
Hi Florencia,
We did not test this recipe in an air fryer, so not sure how the outcome will be.
Please let us know how it goes!
I finally got around to trying these tonight and they are amazing! Even my picky eater spouse approved of them. I did serve mine with tonkatsu sauce and they’re good with and without. I didn’t have any bacon and swapped in some fried onion bits (the kind Trader Joe’s sells in the fall) for the onion (said picky eater spouse has issues with sauteed onions).
Hi Dawn!
Thank you very much for trying this recipe and for your kind feedback. We are so glad to hear that it turned out great and got approved!
Thank you for sharing your cooking experience with us!☺️
Hello Nami,
I’m making them right now. They are currently in the fridge for its 30 minutes. I will bake them in 200C for 10 minutes. Can’t wait to try them!
I have a question.. do you know if can I freeze them? And how long they last in the fridge? Thanks!!!
I’ve had these croquettes from restaurants lots of times and absolutely love them, and have been excited to try out the recipe myself. Unfortunately my first attempt was not a success, and I’m not entirely sure why (I have several theories but not sure which one).
I used some different ingredients since I’m now on a medical diet which is pretty restrictive, but the problem doesn’t seem to be with any of them—the problem is with the squash itself. When I tried the croquettes, the filling just didn’t taste like the ones I’ve had before, and honestly aren’t that nice. I’m so disappointed because I literally spent the whole weekend prepping the kabocha (I lack energy/stamina and arm strength, so just cutting it took a long time and required multiple breaks).
This is the first time I’ve tried kabocha apart from restaurant korroke. Assuming the korroke I’ve had before actually were made with kabocha rather than a different squash, my most likely theory is it doesn’t taste good because by the time I had an opportunity to use it (I had trouble finding it in the shops so nabbed it when I saw it, and so it was waiting to be used for quite a few days sitting around in my kitchen) it was past its best. There was a small fuzzy patch I cut off, and a bit of the skin looked a bit discoloured. When I (eventually) cut it open, I thought it didn’t smell that nice, but assumed that was probably just because it was raw. (The smell was similar to how it tastes now, so I know that was a wrong assumption.) The flesh looked a little darker than in the pictures. I did hesitate and wonder whether I should really be using it, but after all the effort and anticipation leading to that point, plus not wanting to be wasteful by chucking it if it was okay to eat, I decided to try it anyway. (I didn’t risk using the skin though.)
Because of aforementioned stamina issue and a lack of proper steaming equipment, I decided to cook the squash in the microwave. Unfortunately I couldn’t cut it into slices to fit, so I tried softening the halves up in the oven a bit beforehand (I’d done this earlier in the week on a sugar pumpkin, a lot more successfully). The flesh was easier to cut when it came out but still looked and felt hard to the touch. After a lot of microwaving and checking on it, I realised that some bits had just gone hard and wouldn’t soften. When most of it was finally soft enough to mash, I mashed it as well as I could. There were still a few small lumps in it but I managed to mash most of it. The mash was then stored in the fridge over two nights because I was unable to do anything more to it on Sunday or at all yesterday. This morning when I was scooping it into balls, I was surprised how easy it was, and got my hopes up that meant it would be a success.
I coated the balls okay (with low protein ingredients, but that wasn’t the issue) and deep-fried the first six, stopping there to try some for lunch. Unfortunately, as I’ve said, the filling just didn’t taste that nice. They’re edible (assuming I’m not sick later) but just don’t taste good, and I’m feeling pretty upset now, it seems like such a waste of effort. I don’t know if the problem was a bad squash, the wrong squash (it was in a “mixed squash” box so although it looks like a kabocha both outside and inside, there’s a possibility I got it wrong; I almost mistook a different kind of squash for kabocha the other day, so I guess they can look pretty similar) or I cooked it wrong or not enough. I used the entire squash as well, so made double the recipe, and have a plateful of korroke sitting in my kitchen waiting to be fried, and I can’t make up my mind whether to or not. I suppose I could just put them in the oven so at least it’s less effort. I hate wasting food (and time and energy) so I can’t bring myself to just throw them away but I don’t particularly want to eat them either.
I don’t know if you can offer any advice on what I did wrong without having seen/tasted for yourself, but if you can think of anything, please let me know.
Hello Claire! Thank you so much for your detailed feedback. From your description, my first thought was:
1) Maybe it wasn’t really kabocha even though it looked like it and you did have a second thought, which made me wonder it’s a possibility (especially you know the kabocha’s taste from your previous dining experience). Kabocha has a really sweet and delicious taste after being cooked. Not dull taste, it’s pretty obvious it’s sweeter than any squash. If you taste it and it doesn’t recall the kabocha taste, I feel like it was a different variety. Squash, in general, is not so tasty (in my opinion… after growing up with kabocha only, other varieties of squashes and pumpkins are all tasteless to me).
2) Cooked kabocha can last 2 days in the fridge if you keep well. IF the kabocha wasn’t fresh, and keep it even longer in the fridge, maybe that might be the cause of inferior taste.
From reading your feedback, I just don’t think you had kabocha because steamed/cooked kabocha has a wonderful flavor on its own even without making into korokke…
I’m sorry you had to spend so much time to make these. 🙁
Thanks for your reply. You’re probably right about it not having been kabocha. Unless I find actual kabocha definitively labelled as such, I’ll make them with butternut squash or sugar pumpkin in future, since I know I like those 🙂
Hi Claire! Thanks for your response! Keep me posted, and hopefully, you will find the right kabocha next time. It’s much sweeter than butternut squash.:)
About how much prepared kabocha is in this recipe? A little over a pound? Measured in cups would be great! I have a freezer full of it. My friend grows them in her garden! Her favorite way to eat kabocha is stirfried with butter, salt, and ginger! Or garlic if she wants savory. Lol. I like it mashed with a little butter, cinnamon, a hint of brown sugar, and cardamom. Though I can’t wait to try this savory korokke. Maybe it will be a new favorite! Kabocha is so sweet and yummy.
Hi Ammie! I didn’t measure after the seeds were removed. Probably a little over a pound. Yes, kabocha is naturally sweet and so delicious and I love how your friend and you cook with kabocha! I hope you enjoy this recipe! 🙂
Shalom, can you make these ahead and freeze to cook at later date?
Thank you for ease to cook Japanese recipes
Hi Paulette! You can do that. Or I usually recommend to deep fry them first, let cool completely, and then freeze. When you’re ready to eat, put them in the oven (or oven toaster) without defrosting. 🙂
Hi Nami! I plan to freeze these after the deep fry. What oven temperature do you recommend and for how long, so they will be ready to eat again? Thank you so much!
Hi Teresa! 325 F to 350 F for 15-20 minutes (depending on thickness) would be good!
Is it possible to roll the korokke ahead of time to fry later? Thank you 🙂
Hi Michael! I wouldn’t leave the panko-breaded rolls for too long in the fridge but you can leave it for maybe half day? Possibly overnight, but I haven’t done it so I am not 100% sure if the water from veggies starts to release moisture etc…
Okay, thanks. I fried a couple the same day and they were delicious! Like you had said, the bacon makes a huge difference. Thank you so much for your recipes and blog posts, they are a huge blessing!
Hi Michael! I’m glad to hear that you enjoyed it! Thank you so much for your kind words. I’m just happy that you enjoy them. 🙂
Can you it into balls and put in fridge overnight and next day tool it in the Panko mixture and fry it?
Hi Shirley,
Yes, you can.
You can also fry it and store them in an airtight container and freeze up to a month. To reheat, put the defrosted or frozen croquettes on a baking sheet lined with aluminum foil or parchment paper. Bake at 350 ºF (180 ºC) for 10-15 minutes for defrosted ones or about 35 minutes for frozen ones. (Check if the inside is warm before serving.)
We hope this helps!
