Ingredients

Scale
  • 2 cups filtered water
  • 4 oz kombu (dried kelp)
  • 1 cup mushrooms, sliced (cremini, shiitake, or button)
  • 1 medium carrot, diced
  • 1 medium celery stalk, diced
  • 2 garlic cloves, minced
  • 1 tablespoon soy sauce
  • Pinch of freshly ground black pepper
  • 3–5 dried shiitake mushrooms (optional)
  • 1/2 leek, white part only, sliced (optional)
  • 1-inch piece fresh ginger, sliced (optional)
  • 1 bay leaf (optional)
  • 1 tablespoon wakame seaweed (optional)
  • 2 scallions, chopped (optional)
  • 1 tablespoon nutritional yeast (optional)
  • 1/2 teaspoon dried thyme (optional)

Instructions

  1. Combine water and kombu in a large pot and let soak for 10 minutes undisturbed.
  2. Add sliced mushrooms, diced carrot, diced celery, minced garlic, and any optional ingredients to the pot.
  3. Place pot over medium-low heat and bring to a gentle simmer (avoid boiling).
  4. Maintain a gentle simmer for 20 minutes uncovered.
  5. Remove and discard the kombu using tongs or a slotted spoon.
  6. Stir in soy sauce and black pepper, adjusting seasonings to taste.
  7. For a clearer broth, strain through a fine-mesh sieve (optional).
  8. Allow to cool completely before storing if not using immediately.

Notes

This broth can be refrigerated for 4-5 days or frozen for up to 3 months.

For a more concentrated stock, simmer the strained broth until reduced by half.

Avoid boiling kombu as it can release bitter flavors and create a slimy texture.

Use mushroom stems for extra flavor—they’re packed with umami compounds.
