🍲 Ingredients

Shiitake Mushrooms: One of the more popular mushrooms, shiitake mushrooms are loaded with a rich, earthy flavor. And like this recipe, they are best when simply sautéed in a pan with just a few ingredients.

Silken Tofu: Did you know there are different kinds of tofu? This udon noodle soup recipe calls for silken tofu, which is also referred to as soft, silk, or Japanese-style tofu and has a softer consistency than regular tofu. Because of its softness, it crumbles more easily than regular tofu and has more of a creaminess than regular tofu.  

Miso: Miso is a Japanese seasoning. It is a thick paste produced by fermenting soybeans. It is often used in Asian-inspired soup recipes and will be found in most grocery stores in the refrigerator section.

👩‍🍳 How to Make Udon Noodle Soup

  1. Prep your ingredients by dicing your onion, mincing your garlic and ginger, and slicing your mushrooms
  2. Next, add 1 tbsp sesame oil into a small soup pot, and warm it over medium heat before adding the onion, garlic, and ginger
  3. Cook the ingredients, stirring often to make sure it doesn’t stick to the bottom of the pot and cook evenly. These should cook for about 3-4 minutes or until they’re soft
  4. Add sliced mushrooms and saute for 2-3 minutes, allowing them to absorb the beautiful, fragrant flavors of the garlic, ginger, and onions
  5. Add vegetable stock and miso paste. Alternatively, you can use vegetable bouillon and water if you don’t have veggie stock on hand. Bring to a simmer (turn up the heat if needed)
  6. Cook until miso is dissolved, about 4-5 minutes
  7. Next, add udon noodles, tamari (or soy sauce) and spinach. Cook for 3-4 minutes until noodles are cooked and warmed through. Be sure not to overcook your noodles
  8. Turn the heat off, stir in your tofu, taste, and add more soy sauce as needed
  9. Pour into your serving bowl and top with green onions and sriracha if you like some spice

👝 How to Store Leftovers

This soup is best consumed freshly made, as when stored, the noodles can absorb a lot of the liquid. If you want to meal prep this, or store the leftovers, I suggest cooking and keeping the noodles separate from the broth and warming them up together on the stove when ready to eat.

Udon is a thick noodle made from wheat flour, used in Japanese cuisine. There is a variety of ways it is prepared and served. Its simplest form is in a soup as kake udon with a mild broth called kakejiru made from dashi, soy sauce, and mirin. It is usually topped with thinly chopped scallions.

This is one of my “go to” soups on a cold day. It’s so flavourful and delicious. It’s so nice to be able to make something like this at home. 🙂

the dressing in the recipe card is the recipe… we added our twist to it (hers only has 3 ingredients)

Susan Flewelling

I am definitely going to make this soup – have you tried freezing it? I like to make extra portions of soups and freeze them for later.

Maria Koutsogiannis

you know what, I haven’t frozen this one yet! I gobbled it up so fast but honestly I imagine it freezes just fine!
