Equipment Needed:

  • Large 12-inch pot or Dutch oven
  • Whisk
  • Cutting board and sharp knife
  • Measuring cups and spoons

Ingredients:

For the Soup Base:

  • 1 tbsp (15ml) neutral oil (e.g., sesame, canola, or grapeseed)
  • 2 cloves garlic, minced
  • 1 tbsp (15g) grated fresh ginger
  • 6 cups (1.4 L) vegetable broth
  • 1/4 cup (60g) white or yellow miso paste
  • 2 tbsp (30ml) soy sauce or tamari
  • 1 tbsp (15ml) sriracha, or more to taste
  • 1 tsp (5ml) rice vinegar

For the Noodles & Veggies:

  • 8 oz (225g) dried ramen noodles (discard flavor packets) or other quick-cooking noodles
  • 2 cups (60g) baby spinach or chopped bok choy
  • 1/2 cup (70g) sliced mushrooms (optional)

Step-by-Step Instructions:

  1. Sauté Aromatics: In the large pot or Dutch oven, heat the neutral oil over medium heat. Add the minced garlic and grated ginger. Sauté for 1 minute until fragrant, being careful not to burn the garlic.
  2. Build Broth: Pour in the vegetable broth. Add the miso paste, soy sauce, sriracha, and rice vinegar. Whisk everything together until the miso paste is fully dissolved and the broth is well combined. Bring the broth to a rolling boil.
  3. Cook Noodles & Veggies: Add the ramen noodles (or other quick-cooking noodles) and sliced mushrooms (if using) to the boiling broth. Reduce the heat to medium-low, cover, and cook for 5-7 minutes, or according to noodle package directions, until the noodles are tender.
  4. Wilt Greens & Serve: Remove the lid. Stir in the baby spinach or chopped bok choy. Cook for 1 minute, stirring gently, until the greens are just wilted.
  5. Serve: Ladle the hot soup immediately into bowls. Serve with optional garnishes.

Serving Suggestions:

  • Top with sliced green onions, a sprinkle of toasted sesame seeds, and an extra drizzle of sriracha.
  • Add a soft-boiled vegan egg (store-bought or homemade) for extra protein.
  • Serve with a side of crispy baked tofu cubes.

Storage & Reheating:

Storage: For best texture, this soup is best enjoyed fresh. If storing, keep the cooked noodles separate from the broth to prevent them from becoming too soggy. Store cooled broth and noodles in airtight containers in the refrigerator for up to 3 days. Reheating: Reheat the broth in a saucepan. Add the noodles (or fresh noodles) and veggies just before serving.

Meal Prep Tip:

Broth Base: Prepare the entire soup broth (Steps 1 & 2) up to 3 days in advance and store it in a sealed container in the fridge. On the day of, simply reheat the broth, add fresh noodles and greens, and serve!

Pro Tips & Variations:

Tip: Miso Care: Avoid boiling miso paste for extended periods, as this can diminish its delicate flavor and beneficial probiotics. Add it to the broth and whisk until dissolved, then bring it just to a boil. Variation: Added Protein: Stir in 1 cup of shelled edamame or 1/2 cup of pan-fried crumbled tempeh during the last 3 minutes of cooking.
