Ingredients

• 8 cups water
• 1 piece kombu (dried kelp), about 4×4 inches
• 6 dried shiitake mushrooms
• 1 large onion, peeled and halved
• 3 cloves garlic, smashed
• 1-inch piece of ginger, sliced
• 2 medium carrots, roughly chopped
• 2 stalks celery, roughly chopped
• 3 tablespoons soy sauce (or tamari for gluten-free)
• 1 tablespoon mirin (Japanese sweet rice wine)
• 2 tablespoons white miso paste
• 1 teaspoon toasted sesame oil
• Optional: 1 sheet dried seaweed (wakame)

Equipment

• Large stockpot (at least 6-quart capacity)
• Fine mesh strainer or cheesecloth
• Wooden spoon or ladle
• Measuring spoons and cups
• Sharp knife and cutting board
• Heat-resistant bowl (for dissolving miso paste)

Instructions

1. Prepare the kombu: Rinse the kombu gently under cold water to remove any surface salt or dirt. Place it in a large stockpot with 8 cups of cold water. Let it soak for 30 minutes to start releasing its umami flavors.
2. Add dried shiitake mushrooms: After soaking the kombu, add the dried shiitake mushrooms to the pot. These mushrooms add an earthy depth that’s essential for vegetarian ramen broth.
3. Simmer the broth: Slowly heat the pot over medium heat. Just before the water reaches a boil (when small bubbles appear around the edges), remove the kombu. Boiling kombu can make the broth bitter.
4. Add aromatics and vegetables: Add the onion, garlic, ginger, carrots, and celery to the pot. Reduce heat to low and let the broth simmer gently for 45 minutes to 1 hour, uncovered. This slow simmer extracts maximum flavor from the ingredients.
5. Strain the broth: Using a fine mesh strainer or cheesecloth, strain the broth into another large pot or bowl. Press the vegetables lightly with a spoon to extract as much liquid as possible. Discard the solids.
6. Season the broth: Return the strained broth to the stove over low heat. Stir in the soy sauce, mirin, and toasted sesame oil.
7. Add miso paste: Place the miso paste in a heat-resistant bowl. Ladle a small amount of hot broth into the bowl and whisk until the miso dissolves completely. Then, stir the miso mixture back into the broth pot. Do not boil the broth after adding miso, as it can kill the probiotics and alter the flavor.
8. Optional wakame addition: If using dried wakame, soak it in warm water for 5 minutes, drain, and add to the broth at this stage for extra sea flavor and texture.
9. Final taste check: Taste the broth and adjust seasoning if needed, adding more soy sauce or mirin to balance saltiness and sweetness.
10. Serve hot: Ladle the broth over cooked ramen noodles and your choice of vegetarian toppings like tofu, green onions, corn, or soft boiled eggs.

Tips & Variations

Tip: Use high-quality kombu and dried shiitake mushrooms for the best broth flavor. These ingredients are the backbone of your broth’s umami profile.

Variation: For a spicy twist, add a teaspoon of chili oil or a small slice of fresh chili pepper during the simmering step.

Tip: To boost protein, add cubes of silken or firm tofu as a topping or directly into the broth just before serving.

Variation: Substitute white miso with red miso for a stronger, earthier flavor, but reduce the amount to 1 tablespoon.
