Instant Pot Tonkotsu Ramen has a broth that is bursting with flavors! Served with chashu pork, ramen noodles soft boiled eggs, miso tare, and mushrooms!

Noodle dishes are so comforting that I enjoy them even in the hot months of summer! I love Asian-inspired dishes like this, and these other recipes, too: Yum Yum Sauce, Chicken Katsu with Tonkatsu Sauce, and Korean Fried Chicken!

Pressure Cooker Tonkotsu Ramen

Instant Pot Tonkotsu Ramen has all that you need for a complete meal! It has noodles, protein, and veggies swimming in a rich broth.

The broth comes from extracting flavors by boiling pork, specifically the bones. But this will not take so long because, in this recipe, we are using the handy Instant Pot.

We are also making chashu pork belly from scratch in this recipe. These are super tender, melt-in-your-mouth pieces of meat that add to the heartiness, texture, and flavors of this dish.

And the miso ties everything together so well! Learn this recipe and enjoy Japanese food at home on any day!

What is Tonkotsu Ramen?

It is a noodle dish is famous in Fukuoka and Kyushu, Japan. It has a cloudy broth that is primarily made by boiling pork bones with a little bit of meat on them. The collagen in those bones turns into gelatin through the boiling process.

Why is Instant Pot ramen so good?

Typically, you will not attempt to make this dish from scratch because of the waiting time. It may take you at least 12 hours of giving the bones a rolling boil to get that milky broth.

But if you have an Instant Pot, then make this at home! Here are the reasons why:

  1. It is much faster to boil the bones using a pressure cooker than using other means.
  2. Making it at home using your IP is cheaper.
  3. You get to control what goes into it.

What is Tonkotsu broth made of?

It is made of pork bones stock and aromatics such as garlic, onion, and ginger and garnished with some green onions.

How to make Instant Pot Tonkotsu Ramen?

Prepare the broth.

  • Soak: Put the bones in a large pot and cover with cold water for 12 hours. Replace the water with boiled water and use the IP to simmer the bones for 10 minutes. Cancel, drain, and then transfer the bones into a bowl of cold water. Remove the fat.
  • Pressure-cook: Clean the pot and use it again. Cook the aromatics and bones submerged in water on HIGH for 90 minutes followed by a natural pressure release of 20 minutes.

Prepare the toppings.

  • Sous vide the meat: Vacuum-seal the pork belly and marinade in a resealable bag. Then, cook the meat for 10 to 11 hours at 170 degrees Fahrenheit. Let it cool before slicing.
  • Make the miso tare: Combine and simmer the ingredients for 5 minutes.
  • Boil the eggs: Submerge the eggs in water, boil, then put them in cold water to prevent the yolk from setting firmly. Cut in half right before serving with the ramen.


  • Boil the noodles: Follow the directions in the packaging, usually, this takes about 4 minutes. Cook the mushrooms alongside the noodles to soften them up.
  • Fry: Lightly fry the chashu pork belly until lightly browned.
  • Assemble: At the bottom of the bowl, put the miso tare. Pour in the broth and stir. Add the noodles, more broth, and top with the eggs, mushrooms, pork, and green onions.

Best topping for Tonkotsu Ramen:

Here are more suggestions aside from the egg, mushrooms, chashu, and green onions:

  • bamboo shoots
  • cabbage
  • diced onions
  • nori sheets
  • pickled ginger
  • pickled mustard
  • bean sprouts
  • boiled spinach
  • sesame seeds

How to store it?

You can refrigerate the broth for 3 days in an airtight container or freeze for up to 3 months. You can also freeze the chashu pork belly.

Recipe Tips:

  • Serve this with dumplings, crispy sides like fried chicken, a light salad, or even white rice!
  • Giving the aromatics a nice char first before adding them to the water to make the broth develops a deeper flavor.
  • You can also add pieces of chicken backs and feet to the broth for another flavor dimension.

This looks so delicious. My family loves ramen so I bet they will like this.



I have never tried this Asian dish. It looks really unique and fresh.



Holy wow! That looks absolutely amazing! I love real, honest to goodness ramen. I've never tried making my own before.


Lisa Joy Thompson

This looks so amazing! I love ramen but haven't made it in the instant pot. I'll have to try this!



I am part Japanese and grew up on both Tonkatsu and Ramen. Combining them is genius!



I am loving the flavors of this dish. I haven't tried Japanese food before. I'm looking forward to it.



I really love how flavorful this looks!

My family especially my eldest daughter absolutely loves ramen. This would be a great recipe to make for dinner, I'm sure they'll love it.

This was unbelievable. I used cooking wine instead of sake just out of pure laziness. I've been to at least 50 ramen spots. Most of them delicious. This recipe is the best ramen I have ever tasted. Thanks for sharing!


Thank you!



Hi! is there an alternative to preparing the chashu? I do not have a sous vide.


You can simply steam it and after that light brown it.
