A Breakdown of the Ingredients

Soup Ingredients

  • Avocado Oil: A neutral oil that’s perfect for sautéing garlic and ginger, adding a subtle richness to the flavorful broth. A dash of sesame oil will provide a nutty flavor if that is what you prefer.
  • Garlic and Ginger: The aromatic duo that forms the backbone of the soup’s flavor.
  • Miso Paste: The star ingredient that provides the signature umami flavor. I chose red miso past,  but white miso paste works too.
  • Vegetable Broth: A savory base for the soup. Opt for low-sodium broth if you want more control over the saltiness. Use veggie broth to maintain a vegan recipe. If you don’t mind poultry products, chicken broth works, too.
  • Swiss Chard: A nutrient-dense leafy green that adds color and texture. Spinach, baby bok choy or kale can be used as substitutes.
  • Carrots: Thinly sliced for a touch of sweetness and crunch.
  • Rice Udon Noodles: A gluten-free alternative to traditional udon noodles that cook quickly and absorb the delicious flavors of the broth.

Tofu Ingredients

  • Extra-Firm Tofu: Provides protein and a satisfying bite. Extra-firm tofu holds its shape well when cooked.
  • Liquid Aminos: A gluten-free soy sauce alternative that adds a salty, savory flavor to the tofu.

Optional Garnishes

  • Sesame Seeds: Adds a nutty flavor and a visually appealing touch.
  • Green Onions: Brightens up the dish with a fresh, peppery note.

    • Prepare the rice udon noodles according to the package instructions. Once cooked, drain and set aside.

How to Store the Recipe

  • Refrigeration: Store the soup in an airtight container in the refrigerator for up to 3 days. Keep the broth, noodles, and tofu separate to prevent the noodles from becoming mushy.
  • Freezing: While the broth and vegetables freeze well, the noodles and tofu are best stored fresh. If freezing, omit the noodles and tofu, then add freshly cooked ones when reheating.
  • Reheating: Warm the broth on the stove over medium heat or in the microwave. Add the noodles and tofu just before serving.

Tips for Making Homemade Udon Noodles Soup

  • Don’t Boil the Miso Paste: To preserve its probiotic benefits and prevent a bitter flavor, dissolve miso paste in warm broth rather than boiling it.
  • Press the Tofu: Removing excess moisture from the tofu ensures a firmer texture when cooked.
  • Use Fresh Ingredients: Fresh ginger, garlic, and vegetables elevate the flavors of the soup.
  • Customize Your Veggies: Feel free to traditional veggies, like mushrooms. All type of mushrooms an work but oyster mushrooms and enoki mushrooms are popular choices.
  • Control the Saltiness: Start with low-sodium broth and adjust the saltiness with miso paste or liquid aminos as needed.
