Full Ingredients

For the miso-ginger broth

• 4 cups (960 ml) low-sodium vegetable broth or chicken broth
• 1 tablespoon fresh ginger, finely grated (about a 1-inch / 2.5 cm knob)
• 2 cloves garlic, finely grated or minced
• 1 tablespoon low-sodium soy sauce
• 3 tablespoons white (shiro) or yellow miso paste
• Optional for extra depth: 1 teaspoon toasted sesame oil

For the bowl (choose one protein)

• Option A (dumpling bowl): 10–12 frozen dumplings (gyoza/potstickers), about 8–10 ounces (225–280 g)
• Option B (tofu bowl): 8 ounces (225 g) firm or extra-firm tofu, drained and cut into 1/2-inch (1.25 cm) cubes

Noodles and vegetables

• 8 ounces (225 g) quick-cook udon (vacuum-packed, frozen, or shelf-stable)
• 1 cup (150 g) frozen shelled edamame
• 2 packed cups (60 g) baby spinach (or 1 cup / 140 g frozen spinach)

Toppings (highly recommended)

• 2 scallions, thinly sliced
• 2 teaspoons toasted sesame seeds
• Optional: chili crisp or chili oil, to taste
• Optional: nori strips, to taste

Step-by-Step Instructions

Step 1: Set up your ingredients

Grate the ginger and garlic (a microplane makes this quick). Slice the scallions and set them aside for topping. If you’re using tofu, drain it and cut into 1/2-inch (1.25 cm) cubes. If your udon is vacuum-packed or frozen, have it ready to drop in.

Step 2: Bring the broth to a gentle simmer

Pour 4 cups (960 ml) broth into a medium pot. Set over medium heat and bring to a gentle simmer, about 190–200°F (88–93°C). You want steady steam and small bubbles, not a rolling boil.

Step 3: Build flavor with ginger and garlic

Add the grated ginger, grated garlic, and 1 tablespoon soy sauce to the simmering broth. Stir and simmer for 1 minute to infuse the broth.

Optional: Stir in 1 teaspoon toasted sesame oil for a slightly richer aroma.

Step 4: Cook the dumplings (or warm the tofu) and edamame

If using frozen dumplings: Add 10–12 dumplings to the pot, then add the frozen edamame. Keep the broth at a gentle simmer and cook until the dumplings are heated through and tender, 6–8 minutes (check one dumpling to confirm the filling is hot).

If using tofu: Add the tofu cubes and the frozen edamame. Simmer just until the edamame is hot and the tofu is warmed through, 2–3 minutes.

Step 5: Add udon and spinach right at the end

Add the udon noodles and gently separate them with chopsticks or tongs. Cook until the noodles are hot and loosened, 2–3 minutes (or according to package directions).

Stir in the spinach and cook just until wilted, 30–60 seconds. If using frozen spinach, stir and simmer until fully heated, 1–2 minutes.

Step 6: Mix in the miso without boiling

Turn the heat down to low so the soup stops bubbling. In a small bowl, whisk 3 tablespoons miso paste with about 1/2 cup (120 ml) of hot broth from the pot until smooth. Pour the miso mixture back into the pot and stir to combine.

Important: Keep the soup below a boil after adding miso for the best flavor (and to avoid a harsh, overcooked taste).

Step 7: Serve and top

Taste the broth and adjust with a splash more soy sauce if you want it saltier (add in small amounts). Ladle into two deep bowls, making sure each gets noodles, dumplings/tofu, and vegetables. Top with sliced scallions and toasted sesame seeds. Add chili crisp/chili oil to taste for heat.

Pro Tips

• Keep it gentle: Aim for a simmer, not a boil, especially after adding miso. Boiling can mute miso’s sweetness and aroma.
• Dissolve miso separately: Mixing miso with a ladle of hot broth first prevents lumps and gives you a silky, even broth.
• Udon timing matters: Add udon near the end so it stays springy. Overcooking can make it overly soft and cloud the broth.
• Balance the broth: If it tastes a little flat, add 1/2 teaspoon soy sauce or a small spoon of chili crisp. If it’s too strong, add a splash of water or extra broth.
• Make it a true “clean-out-the-freezer” bowl: Corn, peas, sliced mushrooms, or shredded cabbage all work in the same timing as edamame/spinach.

Variations

• Spicy miso-ginger: Add 1–2 teaspoons chili crisp or 1/4 teaspoon crushed red pepper with the ginger/garlic, and finish with extra scallions.
• More umami: Add 1 teaspoon rice vinegar plus 1/2 teaspoon sugar, or add 1/2 teaspoon dashi powder (if you keep it on hand) to the broth.
• Vegetarian protein boost: Use tofu and add 1 tablespoon tahini or peanut butter (whisked into a little hot broth) for a creamier, heartier soup.

Storage & Make-Ahead

This soup is best freshly made (udon keeps softening as it sits). If you want leftovers, store broth and toppings separately from the noodles when possible. Refrigerate in airtight containers for up to 3 days. Reheat the broth gently over medium-low heat until steaming (165°F / 74°C), then add noodles just long enough to warm through. If the noodles have already been stored in the soup, expect them to be softer on day two.
