If you want a comforting by lighter soup for the winter, this recipe is a great one. It’s kinda like a fusion of a traditional chicken noodle soup but with Asian influence with the toppings and udon noodles.

Now, if you’re unfamiliar with Toni Okamoto and Michelle Cehn, they are two powerhouses within the vegan community, and have provided great tools for newbies for years! Toni runs Plant Based on a Budget, and you can see the 4-Ingredient Chocolate Pie recipe from her first book on my blog. Michelle is the founder of World of Vegan which is a great source for recipes and lifestyle tips, plus cute illustrations.

Both Michelle and Toni’s focus for this book is to keep it simple with ingredients, but have tasty recipes that are non-judgmental and easy-to-make. So you have a lot of basics like overnight oats and vegan mashed potatoes, but then some other interesting recipes like ice cream cake and quinoa tots.

Substitutions & Tips

  • Canola oil – any high-temp cooking oil will work here.
  • Bunashimeji or enoki mushrooms – the recipe calls for these longer, skinnier mushrooms as an optional addition, but I do think the mushrooms add a lot to the soup. Shiitake mushrooms would also be great!
  • Vegetable bouillon – I ended up using vegan beef bouillon cubes in my version, and though it was a slightly saltier end product, I thought it was really good! I would maybe use 2 1/2 cubes instead of 3 if going that route next time.
  • Napa or green cabbage – I’ve never had an issue finding Napa cabbage in stores, but if yours doesn’t have it, try an Asian market! (You can also find the mushrooms there, too)
  • Udon noodles – as mentioned in the recipe’s description, udon noodles are long, flat Asian noodles that can be found in many stores, but most definitely in an Asian market when in doubt! (I found my dried noodles at Sprouts Market)
  • Green onions – these are listed as optional but I definitely recommend you top your soup with these.
  • Additional toppings – Toni and Michelle suggest adding cubed, extra-firm tofu to stretch this soup further in terms of helpings and being satiating. And while they didn’t mention it, I added some extra sriracha, toasted sesame oil, and sesame seeds for more flair when eating the leftovers and looooved it!

Vegan Spicy Udon Noodle Soup

Yield: 4 to 6 servings
Prep Time: 15 minutes
Cook Time: 20 minutes
Total Time: 35 minutes

"It’s no secret that we are crazy for noodles! We love them when it’s hot, and when it’s cold, and especially when they’re suspended in a piquant broth surrounded by perfectly cooked vegetables. You can find dried udon noodles in the Asian section of many grocery stores, or fresh udon noodles at many Asian markets. They vary considerably in size, shape, and consistency, so you might want to try a few different kinds to find your favorite." Reprinted with permission.

Ingredients

  • 1 tablespoon (15 ml) canola oil
  • 1 small yellow onion, diced
  • 2 ribs celery, sliced
  • 1 large carrot, julienned or diced
  • 3 large cloves garlic, minced
  • 1 cup (60 g) bunashimeji or enoki mushrooms (long, skinny mushrooms) (optional)
  • 9 cups (2.12 L) water
  • 3 vegetable bouillon cubes
  • 2½ cups (190 g) shredded napa or green cabbage
  • 1 (12-ounce, 340 g) package dry udon noodles
  • 1 tablespoon (15 g) Sriracha sauce
  • Ground black pepper, to taste
  • 2 green onions, sliced, for garnish (optional)
  • ½ sheet sushi nori (toasted seaweed), finely sliced, for garnish (optional)

Instructions

    1. In a large soup pot over medium-high heat, heat the canola oil. Add the onion, celery, carrot, garlic, and mushrooms (if using), and sauté, stirring occasionally, for 5 minutes or until the onion is tender and translucent.
    2. Pour in the water and bring to a boil. Add the bouillon cubes, cabbage, and noodles, and cook for the amount of time suggested on the package.
    3. Remove from the heat and stir in the Sriracha sauce and pepper.
    4. Divide the soup among single-serving bowls. Garnish each bowl with a sprinkle of green onions and finely sliced sushi nori (if using them).

Notes

"Friendly Suggestion: Make this soup stretch further by adding a drained and diced block of extra-firm tofu. It will give you a couple of extra servings to enjoy as leftovers, plus a boost of protein. Win-win."
