This comforting Japanese Curry Udon will satisfy your craving for noodles in an instant. The thick, chewy udon noodles served in a rich, fragrant curry soup is simple enough to serve on a busy weeknight.

Curry Udon (カレーうどん) is a popular menu item in Japan, and has been for a long time. It is lesser-known compared to Curry Rice, but the flavorful curry sauce is just as fulfilling in a soup with udon.

To me, the chewy noodles have a special ability to soothe the soul. When you blanket it with a rich curry soup, you just want to grab your chopsticks and slurp away. Curry Udon is one of the most satisfying noodle soups. It’s easy to whip up in under 30 minutes, too! It’s rich and flavorful, with just a tinge of sweetness in each spoonful.

Ingredients You’ll Need

  • protein of your choice – I used bite-sized pieces of thinly sliced pork loin that cooks in seconds; you can substitute chicken, beef, or seafood; for vegan curry udon, use tofu or shiitake mushrooms
  • onion
  • green onions (scallions) – for garnish
  • udon noodles – read more about it below
  • dashi (Japanese soup stock) – make Awase Dashi or use a dashi packet or powder; for vegans/vegetarians, make Vegan Dashi
  • Japanese curry roux – use store-bought Japanese curry cubes or make your own; read more about it below
  • soy sauce

How to Make Curry Udon

Make this satisfying noodle dish in under 30 minutes! Here’s an overview of the instructions:

  1. Make the dashi in a saucepan or pot.
  2. Stir-fry the onion and protein of your choice in a frying pan with neutral oil.
  3. Add the dashi and curry roux to the pan and simmer over medium-low heat.
  4. Boil the udon noodles in a large pot of water and drain.
  5. Serve the noodles in individual bowls. Pour the curry soup on top.

What is Japanese Curry Roux?

Japanese curry is quite different from Indian and Thai curries and is suited the Japanese palate. It is thicker, milder, and sweeter, with a stew-like consistency. It’s ideal for curry novices or those who prefer a gentler, sweeter flavor.

The packages include curry roux.

For this quick curry recipe, I take the convenient route with store-bought curry roux. Nowadays, you can even find the rectangular packages of Japanese curry roux at major American grocery stores. Look for it in the Asian or global food aisle.

It’s also possible to make your own from scratch! Homemade curry roux is easier to make than you might think and keeps well in the freezer. You need just five ingredients—butter, flour, Japanese curry powder, garam masala, and (optional) cayenne pepper. I recommend S&B brand curry powder for an authentic taste.

Which Udon Noodles to Use

The packages include udon noodles.

Thick and chewy udon noodles are so delicious! You can choose from frozen, refrigerated, or dried udon noodles. However, I only recommend getting frozen udon noodles (choose one called “Sanuki udon”) or dried udon noodles as they have a better texture than refrigerated udon noodles.

You can also make homemade, fresh udon noodles from scratch! It’s easy and fun, and the delicious handmade noodles are far superior to store bought.

Instructions
 

  • Gather all the ingredients. Break the boxed roux into cubes and use 2 cubes Japanese curry roux (keep the leftovers in an airtight container and store in the refrigerator/freezer for 1–3 months). Prepare 3 cups dashi (Japanese soup stock) using your preferred method.
    Curry Udon Ingredients
  • Thinly slice ½ onion and 2 green onions/scallions. Set aside the green onions for garnish.
    Curry Udon 1
  • Preheat a medium pot or Dutch oven (I used a 2.75 QT Staub) over medium heat. When the pot is hot, add 1 Tbsp neutral oil. Next, add the onion slices.
    Curry Udon 2
  • Sauté the onion slices for 2–3 minutes. Then, add 6 oz thinly sliced pork loin that you‘ve cut into bite-sized pieces.
    Curry Udon 3
  • Cook the meat until it‘s barely pink. Next, add 1 Tbsp sake.
    Curry Udon 4
  • Add the dashi to the pot and cover with the lid. Reduce the heat to medium low and cook for 5 minutes.
    Curry Udon 5
  • When simmering, skim off the scum and fat from the stock with a fine-mesh skimmer and continue to cook.
    Curry Udon 8
  • Meanwhile, start boiling a large pot of water for the udon.
    Curry Udon-step by step-20
  • After 5 minutes of simmering the stock and meat, turn off the heat. Next, put a cube of curry roux in a ladleful of hot stock.
    Curry Udon 9
  • With chopsticks or a spoon, dissolve the roux cube completely in the ladle, then release it to the soup. Repeat with the next cube. Tip: You don‘t want to eat a chunk of undissolved curry roux, so take your time to dissolve it completely.
    Curry Udon 10
  • Add 2 tsp soy sauce and mix well. Turn off the heat and cover with the lid to keep it warm.
    Curry Udon 11
  • When the water is boiling, cook 2 servings udon noodles according to the package instructions (for this Sanuki udon, I heated the frozen noodles in boiling water for 1 minute).

To Serve

  • Drain the noodles and divide into two bowls. Pour the curry soup over the udon noodles. Top with the green onions and serve immediately.

To Store

  • Keep the leftover curry soup in a glass airtight container and store it in the refrigerator for up to 3 days and in the freezer for a month. Defrost in the refrigerator for 24 hours and reheat in a pot. I recommend cooking the udon noodles just before serving.

Hi Nami,

Thanks for another great recipe as always 🙂 I just have a quick question. I made Curry Rice today and there is leftover curry (with meat, carrot and potato). Is there any correct way to dilute the leftover curry to make this Curry Udon?

Thank you very much in advance. Have a nice day!

Hi Nami! Thanks a lot for the quick response 🙂 However, I only managed to read your reply now as the notification somehow ended up in the Spam mailbox 🙁 (maybe because the email address of the notification is different from the newsletter one). I have marked it as not spam now 🙂

Hi Nami,

Im wonderinf if you also have a recipe for stir fry kare udon? It was one of my favorites when I was living in Japan.

Thanks!

I ended up making this two nights in a row at the behest of my fiancee! This recipe is excellent and really easy to follow. Thank you so much for sharing this delicious recipe!

Love your recipes Namiko! I’ve recently begun to cook with curry. I was just wondering if instead of curry cubes I could use powder. If so, how much powder per ml of water?

I happen to have a few blocks in the fridge from earlier this week and can’t wait to try this out tomorrow.

The Curry Udon was a very nice and fast to make, which was what I just needed for tonight as I was home a bit late. This was also a slightly different way of enjoying curry because of the Japanese seasoning with Dashi stock, Sake and Soy Sauce.

As with other recipies, I was really satisfied with this – 5 stars.

ありがとうございます!

This may seem like a silly question, but I love your soup skimmer. Where did you get it? I can’t find any like it. 🙁

Hi Nami,

Your curry udon looks amazing! 🙂
Instead of using a block of Japanese curry roux like you, I really want to try your curry roux recipe.
So I was wondering how many tablespoons/grams of your homemade roux do I need to use for 2 blocks of curry roux ?

Bye, Cassandre.

Nami,

Yes, don’t worry, it helps. 😉 I think I get it, not really an exact science but more like cooking with your taste buds and heart, right? how you feel it in the moment… I tried this dish a few times at the restaurant and I like it thick too (finish udon and drink all the dashi like a soup, it’s wonderful =D).

I think I’ll try cooking this curry udon next week. I’ll come back later and keep you updating on the amount of curry roux I used!

So, I’m back ! 🙂

First, I made homemade curry roux according to your recipe. Well… I think I was wrong somewhere. I tried to convert tablespoons in grams and maybe it’s here I made a mistake. Then my roux turned brown after only 5 minutes ; I think I burned it ><'… My homemade curry roux came closer to the one I buy normally at 70-80% maybe? But it was good, not the taste of Japanese curry I expected but good nonetheless! 🙂 I will definitely give it another try.

Now the udon! Obviously, because of my roux, it wasn’t the taste of the one I eat at the restaurant. Same here, 70-80%?

I used for about 30 grams of roux (2 tablespoons?) for 1 block, but my mistake was that I forgot that the curry would thicken so after 4 minutes of heating the curry, it was really really thick and I had to add some water.

Next time, I’ll cook it with curry sauce mix and I will get the right taste! 😉

Thanks for the great recipe. I just tried it out and it’s awesome.

I made this tonight and was going to take a picture, but my husband ate everything! He would like to thank you, Nami, for turning me into a Japanese cook!

Could I used dried udon noodles instead? Before I buy fresh udon noodles I want to use up more of the dried Udon I accidently bought in bulk. Thought I was ordering soba and ended up with 12 packages of udon to use up.

And this recipe looks fantastic. I love curry. ^_^

Just found your blog while searching for a Curry Udon recipe. I tried it out today with the only difference that I substituted the meat for shiitake mushroom since I didn’t have any meat to use, and it was delicious! Thank you for the wonderful recipe, now I gotta try some others 🙂

I just made this last night and it was wonderful!! We currently live in Okinawa and have had the joy of having curry udon at one of the local udon restaurants here. I am so glad that I now have a recipe for it! I accidently left out the soy sauce, however, I think the soup did just fine without it. Also I added an extra block of curry roux…. we like curry flavor 😉 This is now my new, go to cold weather comfort food. Thank you, Nami, for this wonderful recipe 🙂

This was delicious! This recipe is definitely going into our family’s box of regular meals! Easy, quick and flavorful! Only downside is that the husband and I are now even more nostalgic of our trip to Japan! Thank you!5 stars

Sanuki udon is three times more expensive than the udon I normally purchase (some random brands) but since it is recommended, I have decided to give it a go when I plan to try out this curry udon recipe. Oh my, the udon is marvelous! Just as the udon I eat in the fine dining Japanese restaurants. Thank you fore the recommendation, Nami : )

Yes, you are absolutely right, Nami! I doubt I will satisfy with the usual udon now. The texture of sanuki udon is very much better than the regular one so I guess there’s a price to pay : )

p/s: I couldn’t find Ito Togarashi though, not even in Isetan. Maybe I will fake them by cutting the dried chili into tiny threads next time I cook curry udon : ) They look so beautiful as toppings!

Made with leftover curry added a little dashi to make it more soupy! Thanks5 stars

Hi Kirie, Awesome! Thank you very much for your kind feedback!

Yay! you posted the recipe. I can’t wait to make this. I love udon and curry. =)
