Ingredients for vegan ramen broth

The secret to perfect ramen broth is the layering of different flavours. These are the key ingredients you need to make a rich and flavourful vegan ramen broth:

Oat milk vs. Soy milk

My go-to non-dairy milk for ramen has always been soy milk, like for my black sesame tantanmen and white sesame tantanmen. Soy milk adds flavour and a slight sweetness to the broth which contrasts deliciously with the other ingredients.

However, recently I’ve been on a huge oat milk kick because of its ultra creaminess and subtle sweetness which I thought would be perfect for Tonkotsu broth since it is especially rich and creamy. It adds a lot of body to the broth that soy milk lacks (especially the cartoned stuff) so I do recommend oat milk for this recipe.

Vegan Dashi

Coming from the shiitake mushroom and kombu, it adds a ton of umami and extra depth of flavour that would usually come from pork bone broth.

Nutritional Yeast

Another secret ingredient that makes this broth so rich, creamy and flavourful! It adds a wonderful savouriness and subtle nuttiness.

Sesame paste

Please do not substitute with tahini or it will take on a completely different flavour and you’ll be missing out on that true authentic flavour.

step by step how to make vegan tonkotsu ramen broth

How to make rich and flavourful vegan ramen broth

Homemade ramen broth is actually super easy to make:

  1. Caramelize the onions to bring out its natural sweetness. Then add the garlic and ginger and cook until aromatic. Pour in the vegetable stock and add the kombu. Once broth comes to a boil, add the shiitake mushroom, reduce the heat and let it simmer for 20 minutes.
  2. Remove just the kombu. Transfer the soup into the blender, add the remaining broth ingredients and blend until smooth. Strain the soup using a fine mesh sieve. Taste the soup and season with salt to taste.

Once the broth is ready, add it to some cooked ramen noodles and top it off with all the toppings!

Ramen Noodles

There are three main types of ramen noodles to choose from:

  • Fresh Noodles: the tastiest but might be more difficult to find (especially without eggs). My local Asian grocery stores sell packages of frozen ramen (comes with the soup and flavourings) and those are similar to fresh as well.
  • Dried Noodles: can be found near dried soba noodles or udon noodles. It may be levelled as Chuka Men or Chinese style noodles in bundles.
  • Instant Noodles: the most convenient and can be found at Asian grocery stores near the dry noodle section or instant ramen section.

When I’m able to go to my local Japanese grocery store, I’ll use fresh thin straight noodles but here, I used wider wavy dry noodles because thats what I had on hand. Although tonkotsu ramen is typically paired with fresh, thin and straight noodles, there are no specific rules as to which ramen noodles you choose so use whatever style of noodles you like and what you can find!

Ramen Toppings

The most common and traditional toppings for ramen include:

  • sweet corn
  • wood ear mushrooms
  • bamboo shots
  • bean sprouts
  • seaweed
  • scallions
  • rayu
  • mayu
  • sesame seeds

Again, there are no specific rules as to what should go on top of ramen so use anything you like and have on hand that you think will pair well with the broth and noodles! Some of my other favourite toppings include bok choy, enoki mushrooms, aburaage, kimchi and fried tofu puffs.

Vegetarian ramens usually come with an egg, but I added some tofu katsu to this vegan ramen which pairs wonderfully. The katsu actually stays pretty crispy while soaking up the broth!
