Easy and quick homemade Pressure Cooker Spaghetti Bolognese, this delicious recipe is made all in one-pot, perfect for a busy weeknight!
I love cooking the bolognese sauce in my Dutch oven over the stove top, but it takes hours. So today, I’m sharing a quicker alternative and just as tasty, Pressure Cooker Spaghetti Bolognese (圧力鍋スパゲッティボロネーゼ) recipe with you.
Stovetop vs. Pressure Cooker Spaghetti Bolognese
Just to be clear, I am NOT saying that pressure cooker makes better Bolognese sauce. There’s just something magical about slow cooking, as if you are adding love to the food every time you stir. However, just because you don’t have time, you don’t have to give up on homemade bolognese sauce all together.
With a pressure cooker, you can save your time and effort, but achieve full depth of flavor equivalent to the slow-cooking sauce that’s been simmering on the stove top for hours.
And for busy moms who often struggle to put time in the kitchen, that’s a huge win!
3 Key Ingredients for Pressure Cooker Spaghetti Bolognese
1. Soffritto (in Italian, and Mirepoix in French)
What is soffritto? It’s a mixture of finely chopped onions, carrots, and celery (it really depends, but usually in 2 parts : 1 part : 1 part ratio) that are sautéed with olive oil or butter until tender and golden.
It’s an umami-rich magical flavor. It’s used as the flavor base for a wide variety of dishes including soups, stews, stocks, ragu, sauces, risotto, and more.
2. Beef & Pork
I use two types of meat for my bolognese sauce: beef and pork (both about 20% fat). They are both juicy, flavor-rich meat, but when the beef is used by itself, the texture of the meat sauce tends to be harder. Therefore, blending in the pork makes the sauce more tender.
You can use Italian sausages too, but I like my bolognese sauce with ground beef and pork as I grew up eating it this way.
3. Red or White Wine?
Both will work, but I use red wine because it’s a red meat dish. Plus, we can enjoy the rest of the wine with the meal after cooking.
The alcohol in the wine evaporates while the food is cooking, and the only flavor remains. The wine flavor adds complexity and a variety of tastes (acidity, sweetness, etc) to the dish that’s difficult to substitute.
Why Pressure Cooker Instead of Slow Cooker?
I usually use pressure cooking mode on my favorite Instant Pot (I’m not sponsored; I just love this gadget!) rather than slow cooking mode simply because I typically decide on dinner menus pretty last minute.
If you have an electric slow cooker, or slow cooking fits your lifestyle, you can definitely use this recipe as well.
To quickly explain, this Instant Pot is a 7-in-1 Multi-Functional Cooker. It can be a rice maker/porridge maker, steamer, sauté/browning, yogurt maker, and warmer. My mom used stove top pressure cookers at home growing up but they scare me a bit with the loud whistling noise. You also need to stay in the kitchen to control the heat. With the Instant Pot, you can just set and walk away!
A Little Tip for Pressure Cooker Spaghetti Bolognese
As the liquid stays in the pot during the cooking process, not much liquid is lost compared to the stove top. If there is too much liquid for your liking, turn the Instant Pot to “Saute” mode and evaporate some liquid.

Pressure Cooker Spaghetti Bolognese
Ingredients
- 1 carrot (3.2 oz, 90 g)
- 1 stalk celery (3.5 oz, 100 g)
- 1 onion (8.5 oz, 240 g)
- 2 cloves garlic
- 6 button mushrooms
- 8 oz ground beef chuck (about 20% fat)
- 4 oz ground pork (about 20% fat)
Seasonings/Condiments
- 2 Tbsp extra virgin olive oil
- 1 bay leaf
- ¼ cup red wine (4 Tbsp)
- 1 28-oz can whole peeled or crushed tomato and juice (800 ml)
- ¼ cup chicken or vegetable stock (4 Tbsp)
- 2 tsp dried oregano
- 2 tsp dried basil
- 1 Tbsp unsalted butter
- 2 tsp Diamond Crystal kosher salt (and more to taste)
- freshly ground black pepper
To Serve:
- 1 ½ lb spaghetti (4 oz/113 g per person)
- 1 ½ Tbsp Diamond Crystal kosher salt (for boiling pasta)
- Parmigiano-Reggiano or Parmesan cheese
- parsley (I actually love using cilantro instead of parsley. Have you tried it? So good!)
Instructions
- Gather all the ingredients.
- Cut carrot, celery, and onion into small, roughly equal-size chunks. If you don’t have a food processor, simply mince them by hand.
- Put the vegetables m in the food processor and pulse a few times until desired consistency is reached. If a few pieces are too large, do not continue with food processor to get them chopped as you will over-chop the rest. Just mince those remaining pieces by hand. Set aside.
- Mince the garlic. Brush off any dirt and debris from mushrooms and slice them. Alternatively, you can lightly rinse the mushrooms with cool water and pat dry with paper towels, but do not soak the mushrooms (they absorb water like sponge).
- Press the “Sauté” button on your Instant Pot (I use 6-QT Instant Pot) and heat 2 Tbsp olive oil.
- Add minced garlic and 1 bay leaf and stir until fragrant.
- Add the minced vegetables and sauté until onion is tender.
- Add the meat and mix with the rest of ingredients in the pot.
- Add ¼ cup (60 ml) red wine and stir, scraping the juicy bits stuck to the bottom and side of the pot and evaporate the alcohol completely, about 5-7 minutes.
- Add 1 28-oz (800 ml) whole tomatoes (crushed before adding) or crushed tomatoes and ½ cup (120 ml) vegetable broth.
- Add sliced mushrooms, 2 tsp dried oregano, and 2 tsp dried basil on top.
- Cover and lock the lid on the pressure cooker. Make sure the steam release handle points at “sealing” and not “venting”. Press the “Keep Warm/Cancel” button on the Instant Pot to stop “sauté” mode. Press the “manual” button to switch to the pressure cooking mode. Press the “minus” button to change the cooking time to 20 minutes.
- If you’re using a stove-top pressure cooker, you won’t have any buttons to press. Just cook on high heat until high pressure is reached. Then reduce the heat to low but maintain high pressure for about 20 minutes.
- When it is finished cooking, the Instant Pot will switch automatically to the “Keep Warm” mode. Let the pressure release naturally, about 15-20 mins. Meanwhile, boil a large pot of water (4-5 QT), add 2 Tbsp kosher salt, and boil your choice of pasta. Cook according to the package instruction and drain the pasta.
- After de-pressurizing is completed, unlock the lid and add 1 Tbsp unsalted butter and freshly ground black pepper. Taste the spaghetti sauce, and if necessary, season with kosher salt (I added about 2 tsp here). If the sauce is too thin or “soupy” (moisture released from the ingredients), turn on “Saute” mode and reduce the sauce to the consistency you like (I did not need to do that).
- Finely mince fresh parsley. Serve the spaghetti sauce over the pasta. Sprinkle chopped parsley and grated parmesan cheese. Enjoy!
To Store
- You can keep the leftovers in an airtight container and store in the refrigerator for up to 3 days and in the freezer for a month. I recommend packing the sauce in individual portions so you can enjoy later on. It's great emergency food if you're really behind on prepping a meal. Thaw in the fridge overnight and re-heat in a pot over very low heat on the stovetop.
This is a great recipe for those doing BLW that the whole family can enjoy. My 9 month old looooved it and ate an incredible amount. We were in shock, first time for her to get seconds.
I just used low sodium broth and no wine. After reducing the sauce I removed my baby’s portion and then added the salt for everyone else.
Not to mention how little effort this takes… While “cooking” we played and read books. Super stress free Saturday night!
Thank you Nami for the great recipe!
* I made this in a 3 quart IP and it just fits, didn’t have to half the recipe. If anyone else is trying it with a 3 quart, go for it as it is!
Hi Kornelia! Thank you very much for trying Nami’s recipe and sharing your cooking experience with us!
We are so happy to hear your whole family enjoyed this dish!🥰
Hello Nami! I’ve been making your bolognese for 2 years now, my kids love it! May I ask when do we add the butter in this recipe? I think I missed it. Thank you!
Hi Kathy! Thank you so much! So happy to hear you enjoy my recipe. Add the butter at Step 16. It’s just for flavoring, making it a richer taste. 🙂
Can I substitute red wine with cooking wine?
Hi Kimiko! Sure that should be okay… red wine is more appropriate flavor though… next time! 😀
What would you think about using a bit of balsamic vinegar in place of red wine? Would that give it a similar taste and effect? Using less of course.
Thanks!
Hi Katie! Hmm I’ve never used balsamic vinegar in place of the red wine. There is no “vinegar” necessary in the sauce, but a little bit of that won’t hurt I think! Or you can just skip the wine and add more broth. 🙂
This was a little bit of work, but it was so worth it. My son and I made this right after Thanksgiving (thinking … who wants to eat leftovers so soon?). It was the perfect dish. Thank you, Nami for giving me a reason to use my instant pot. Delicious.
Hi Noriko! I’m happy to hear that you and your son enjoyed this recipe! Thank you for your kind feedback! xoxo
I have a stove top, slow cooked Bolognese sauce recipe that my family likes, but mention “Instant Pot” and I’m there! Can’t wait to try this, especially on busy nights! Thank you, Nami!
Hi Donna! Hope you enjoy the recipe! 🙂
Add whole milk just to cover the meat and simmer until most of it has evaporated (about 25min or less in a pressure cooker) before adding the wine and the rest of the ingredients. Given a rounded rich flavour to the ragu. A family favourite and easy to freeze for a quick meal when you have no time cook.
Hi Manoja! Thank you so much for your tip!!!
Nami-san,
Can you recommend a red wine to use? I don’t drink wine so I don’t know which one to buy.
Thank you.
Hi Karen! I have a good wine to recommend for someone who don’t drink. If you can find this small bottle of wine, it’s perfect!

Mr. JOC drinks wine, but I don’t like opening his wine without knowing which one is good etc, so I keep these small wine bottles for cooking. 🙂
Hi Nami,
This is the one recipe that introduced me to your site. I was making spaghetti for years using Ragu or Prego and my family eventually hated it. I was born in and still live in Hawaii and my mother is originally from Yokohama, Japan. When I was growing up, I spent some of my summers in Japan and I remember really enjoying the spaghetti there. It was certainly different from American spaghetti. I did a search for “Japanese” spaghetti when I came across this recipe. I made it and my entire family enjoyed it – even my very picky daughter. Ever since then I have been trying out some of your recipes. Most recently I made Pork Belly Kakuni – so delicious!
I have also been reading your blogs about Japan since we will be visiting there soon. I’m looking forward to visiting Kappabashi Kitchen Town!
Thank you so much for this site! I thoroughly enjoy it. I hope one day you will visit and do a blog on Hawaii.
Lena
Hi Lena! Thank you so much for your kind comment. And your mom is also from Yokohama too (instant connection!). I’m happy to hear you and your family like this recipe. I looove spaghetti bolognese growing up in Japan, so this is my favorite! Thanks for reading our travel posts. Hope they will inspire you to visit some of the places we covered. And big yes on Hawaii! Last time I visited Hawaii was when I was in high school… it was our first family oversea trip from Japan! I was surprised I could still use Japanese! 🙂 My kids really want to visit Hawaii, so it’s on our list to visit soon!

I have leftover tomato paste. Can that be used somehow?
Hi Connie! I use tomato paste in some recipes:

I want to make the Spaghetti Bolognese recipe, but have an 8 qt IP maker. Your IP is 6 qt. How do I adjust your recipe for my 8qt IP? Thank you.
Hi Holly! You can still make this recipe in your 8 QT or you can change “Serving” number to 8 in the recipe card. 🙂
Loved your recipe! Only thing I tweaked is that I added a little sugar to the end product while I boiled it to help reduce some of the liquid. Tastes great! Thank you for the recipe!
Also I used ground turkey!!! ????
Hi Lauren! Thank you so much for your kind feedback, and I’m so happy to hear you enjoyed this recipe!
