Making tonkotsu ramen at home is truly a labour of love. This isn’t some 15 minute miracle insta-ramen recipe. This isn’t even some one day recipe. Making authentic tonkotsu ramen takes time. It takes effort. You have to be a bit crazy to go there. But it’s so good. It’s totally worth it.

Tonkotsu ramen has five major ingredients. Broth. Noodles. Pork. Egg. Tare. Each is important and each takes some doing.

Tonkotsu broth is the heart and soul of any tonkotsu ramen. It’s not difficult but it takes time – 12 to 18 hours. Mostly unattended but you can’t rush this. You can make lots and freeze it though. Two bowls or twenty. Doesn’t matter at all as long as you have a big enough pot.

You can make tonkatsu ramen that's as the best ramen joint in town.

The noodles are the backbone. Noodles were where I struggled the most. The fresh ramen I can get in town sucks. Like really sucks. Ramen noodles are different. They are alkalinated. That’s a fancy way of saying you put baking soda in the dough. Asian stores sell dried Japanese ramen. Look for sodium carbonate or potassium carbonate in the ingredient list. If you can’t find any, another trick is to boil spaghettini or capellini in 8 cups of water with 2 Tbsp of baking soda. That works too. Please don’t use packaged dry instant ramen noodles. Those are completely different. I like them in an I like KFC sort of way (as in I eat it once every few years and then wonder why I did that) but for this they are so wrong…

You can make ramen as good as your local ramen joint.

The pork is called chashu. It’s marinated pork belly and it’s magic stuff. I do mine sous vide for 11 hours at 170F. Conventionally cooked chashu recipes are all over the internet.

Tonkotsu ramen is usually served with medium boiled eggs. I didn’t even know there was such a thing as medium boiled egg until I discovered ramen. Medium boiled is about a 7 minute egg. The whites are firm. The yolk are just barely set.  Just so good.

The tare is the flavour base. This is where you take your ramen in your direction. It can be as simple as salt or as complicated as bacon infused sweet soy miso tare. Up to you.

Pull these 5 elements together and you have wonder in a bowl. If you don’t understand why you’re reading this and think I’m crazy google the best ramen joint in your town. Go taste for yourself. Then judge me. It may seem daunting but it’s a few manageable steps. It’s totally doable if you want it bad enough.

This is adapted from several recipes from the internet. The soy bacon tare is a based on David Chang’s Momofuku Tare 2.0. The chashu pork marinade is from Serious Eats. The tonkotsu ramen broth is adapted from a bunch of recipes on the net.

Tonkotsu ramen is an excellent introduction to Japanese noodle soups. Deeply flavoured tonkotsu pork broth, ramen noodles and chashu pork belly come together to create comfort in a bowl.
Recipe type: Main
Cuisine: Japanese
Serves: 4 bowls
Tonkotsu ramen
  • 8 cups tonkotsu pork broth
  • 12 oz good quality dried ramen noodles
  • 4 large or extra large eggs
  • 2-3 oz enoki or other mushrooms
  • thinly sliced green onions
Chashu pork belly
  • 2 lb pork belly, rolled and tied
  • ¼ cup soy sauce
  • ½ cup sake
  • ½ cup mirin (sweet Japanese wine)
  • ¼ cup of sugar
  • 2-3 cloves whole garlic
  • 2 green onions, coarsely chopped
Soy bacon tare
  • 2 slices good quality bacon
  • ¼ cup soy
  • 2 Tbsp mirin
  • 2 Tbsp sake
  • 4 Tbsp shiro miso
Miso Tare
  • ½ cup shiro miso
  • ¼ cup sake
  • ¼ cup mirin
  • pinch of shichimi togarashi (optional)
  • 1-2 tsp or more kosher salt (depending on how salty you like your ramen).
Chashu pork belly
  1. Combine the soy, sake, mirin, sugar, garlic and green onions in a ziploc bag large enough to hold the pork belly. Stick a straw in the bag and seal the ziploc bag up against it (so the straw is the only opening). Suck as much of the air out as you can and seal.
  2. Sous vide the pork for 10-11 hours at 170F.
  3. Remove pork from the ziploc bag. Discard the bag and marinade.
  4. Let the chashu pork belly cool completely.
  5. Slice across the chashu pork (so you get bacon like slices) - into 8-12 slices about ⅛ to 3/16 inches thick. Reserve. You won't need all the pork for 4 servings.
Soy bacon tare
  1. Combine all the ingredients in a small sauce pan. Simmer at the lowest setting for about an hour. Top up with a bit of chicken stock if needed.
  2. Remove the bacon.
Miso tare
  1. Combine all ingredients in a small sauce pan and simmer at the lowest setting for about 5 minutes.
Medium boiled eggs
  1. Boil large eggs for 6 minutes 30 seconds. If using extra large eggs boil them for 7 minutes 30 seconds. You may have to adjust your times slightly depending on the exact size of your eggs but this should get you pretty close.
  2. Submerge the eggs in cold or ice water to chill. This stops the egg yolks from continuing to set up. Peel. Cut in half.
Assemble the tonkotsu ramen
  1. Boil the ramen noodles in plenty of water as directed by the packaging. If there's no translation on the packaging usually its 4 minutes. You don't need to salt the water.
  2. Cook the mushrooms along side the noodles - you just want them softened.
  3. Gently fry the chashu pork in a non-stick skillet until lightly browned.
  4. Place ¼ of whichever tare you are using in the bottom of four bowls.
  5. Ladle in about ½ cup of the tonkotsu broth into each of the bowls and stir to mix.
  6. Add the noodles. Pour in another 1½ cups of the tonkotsu broth per bowl.
  7. Top with the egg, mushrooms, pork and green onions.
I've provided 2 different tare recipes. Use one or the other or come up with your own.

If you use the miso tare, you can salt your broth directly. That is easier than guessing how salty you want your tare.

If you aren't up for making chashu pork you can substitute roasted pork shoulder. It would be an awesome use of leftover pork roast...

    • It is a lot of work but you can make big batches of tonkotsu broth at once and then freeze it for a quick ramen fix. Just substitute something else for the pork belly and it’s a weeknight dinner.

  1. I’ve never agreed with a statement more. Chashu is DEFINITELY magic stuff! I can’t believe you made a ramen that looks this good and is so authentic at home. I love a good bowl of ramen, but have never dared to make it at home, for fear of messing up this perfect dish. Now, I don’t have to be scared anymore because of your awesome step-by-step instructions. I’m definitely going to try this out!

    • It’s an epic recipe but I think it’s worth it. And it’s a starting point. You can take it a few different ways with the tare and toppings so you can make a big batch of tonkotsu and not get bored!

  2. I absolutely LOVE a good bowl of ramen! Whenever we go to a “big city,”I always have to find the best ramen joint in town.:) However, I have never been brave enough to make it at home (besides you know, the packaged stuff, haha!). These instructions are wonderful! It may be a time consuming process, but for a good quality ramen at home, I’d say it is absolutely worth it. Can’t wait to try it!

  3. Wow! I was intrigued by the photo and then even more impressed with the process! I’m a pretty lazy cook but this would be perfect to make for my daughter for her birthday or something, she loves ramen! Definitely pinning for September;) Thank you!

  4. Love love love me some ramen! And I always feel like the medium boiled egg is the key ingredient. The meat is always hard for me –
    I always end up just doing chicken, but the pork in this recipe definitely kicks it up to the real deal! Thanks for making it so easy!

  5. This looks really good and well worth a try. I had some great Ramen when I worked in NYC a few years ago and some good Ramen in Manchester but other than that I stick with a quick recipe at home but I’ve always wanted to turn it up a notch and I think this could well do it. Many thanks

    • It’s a crazy amount of work making the broth and the pork takes some doing as well but it is as good as a most ramen joints serve. Good luck!

  6. Reading your thought stream is a delight. I enjoy your banter and share much of your humor. I am preparing your tonkostu recipe as I type, yet I am doing it in a pressure cooker to remove some of the time. I know I have to replenish liquid and move things around and such, and hopefully by 6pm tonight I will have given it 14 hours worth of cooking.
    I enjoy your blog.

    • So glad you like the blog (and my sometimes strange sense of humour:-) I never thought of cooking tonkotsu ramen broth in a pressure cooker. I’d be very interested in hearing how that goes.
