Ingredient Notes
(Scroll to the recipe card below for exact measurements.)
Water & Hondashi Powder
This combination creates a quick and flavorful dashi base without extra prep. If you prefer, you can substitute homemade dashi broth for added nutrition and depth.
Tofu
Silken tofu is the most traditional choice, but soft, medium, or firm tofu all work well. Use what you have on hand.
Wakame Seaweed
Dried wakame expands as it cooks, so be sure to break or cut it into small pieces for easy eating.
Miso Paste
To keep this soup gluten free, use miso paste labeled gluten free. White, yellow, or red miso all work—lighter miso is milder and slightly sweet, while darker miso is saltier and more robust.
Green Onions (Optional)
Adds a fresh, savory finish and a pop of color.
Optional Miso Soup Add-Ins
Make this soup your own with additional ingredients such as:
- Mushrooms
- Onions
- Root vegetables (potato, daikon, taro)
- Proteins like shrimp, pork, or extra tofu
How to Make Gluten-Free Miso Soup
- Prepare the broth – Bring water to a boil in a saucepan. Add hondashi powder, wakame seaweed, and tofu. Return to a boil, then reduce heat and simmer for about 3 minutes until the seaweed is fully rehydrated.
- Add the miso – Turn off the heat. Using a mesh strainer, dissolve the miso paste directly into the soup. Tip: No strainer? Dissolve the miso in a small bowl with hot broth, then stir it back into the pot.
- Finish & serve – Add sliced green onions and serve hot.
What to Serve with Miso Soup
Miso soup pairs beautifully with:
- Sushi, sashimi, or nigiri
- Grilled or pan-seared fish
- Fried dishes like tempura, tonkatsu, or chicken katsu
- Rice bowls and noodle dishes
Recipe Tips
- Do not boil the soup after adding miso, as high heat can reduce its flavor and nutritional benefits.
- Always check labels when making gluten-free miso soup—some miso pastes contain barley or wheat.
- Adjust miso quantity to taste, especially when using darker miso varieties.
Storage & Reheating
Storage: Store cooled leftovers in an airtight container in the refrigerator for up to 3 days.
Make-ahead tip: If making a large batch, reserve extra broth before adding miso and only mix in miso just before serving.
Reheating: Gently heat until hot but not boiling. If miso hasn’t been added yet, you may boil the broth, then remove from heat and stir in miso.
