Ingredients You’ll Need
Here’s everything you’ll need to make this warming miso udon noodle soup for two:
-
2 portions frozen or fresh udon noodles
-
4 cups vegetable broth
-
2 tablespoons white miso paste
-
1 tablespoon soy sauce or tamari
-
1 tablespoon sesame oil
-
1 teaspoon grated ginger
-
2 garlic cloves, minced
-
1 small onion, sliced
-
½ block firm tofu, cubed
-
1 cup shiitake or oyster mushrooms, sliced
-
1 cup baby spinach or bok choy
-
1 scallion, thinly sliced (for garnish)
-
Toasted sesame seeds (optional, garnish)
-
Chili oil (optional, for serving)
Kitchen Equipment
-
Medium pot (for broth)
-
Small pot (for noodles)
-
Ladle for serving
-
Cutting board and knife
-
Wooden spoon or spatula
-
Small mixing bowl (to dissolve miso)
Step-by-Step Instructions
1. Sauté the Aromatics
Heat sesame oil in a medium pot over medium heat. Add garlic, ginger, and onions, sautéing for 2–3 minutes until fragrant. This step builds the base of the soup and enhances the richness of the broth.
2. Build the Broth
Add the vegetable broth and bring to a gentle simmer. Stir in the mushrooms and tofu, allowing them to simmer for 6–8 minutes. The tofu will soak up the broth’s flavor while the mushrooms soften beautifully.
3. Add the Miso
Lower the heat. In a small bowl, whisk the miso paste with a few spoonfuls of hot broth until smooth. Stir the dissolved miso back into the pot. Important: never boil miso directly—heat can destroy its delicate flavor and beneficial probiotics.
4. Cook the Noodles
In a separate pot, cook udon noodles according to package instructions. Fresh or frozen udon usually takes just 2–3 minutes. Drain and rinse lightly under warm water to separate strands.
5. Assemble Your Bowl
Place noodles in serving bowls, then ladle broth, tofu, mushrooms, and greens over the top. Garnish with scallions, sesame seeds, and a drizzle of chili oil if you’d like some heat.
Tips and Shortcuts
-
Use Frozen Udon: Frozen udon noodles are nearly identical to fresh and cook in minutes. Keep a pack in your freezer for last-minute meals.
-
Enhance the Broth: Add a splash of mirin or rice vinegar for a subtle sweetness. A piece of kombu (dried kelp) simmered in the broth can deepen umami.
-
Protein Options: Swap tofu for shredded chicken or shrimp if you’re not vegetarian.
-
Vegetable Variations: Try napa cabbage, zucchini, or bean sprouts for extra crunch.
-
Spice It Up: A spoonful of chili paste, a drizzle of chili crisp, or even a few slices of fresh chili can transform the flavor profile.
Recipe Variations
-
Gluten-Free Miso Udon Soup
Replace udon with gluten-free rice noodles and use tamari instead of soy sauce. -
Creamy Udon Soup
Stir in a splash of coconut milk or cashew cream for a rich, velvety broth. -
Miso Udon with Egg
Crack an egg directly into the simmering broth and let it poach for a silky, protein-packed addition. -
Spicy Udon Soup
Add gochujang (Korean chili paste) or sriracha to the broth for a bold kick.
Storing Leftovers
Miso udon noodle soup is best enjoyed fresh, but leftovers can still be delicious:
-
Broth: Store separately in an airtight container for up to 3 days in the refrigerator.
-
Noodles: Keep them separate if possible to prevent sogginess. Toss lightly with sesame oil before refrigerating.
-
Reheating: Warm the broth gently on the stove and add noodles just before serving. Avoid boiling to preserve miso’s delicate flavor.
Freezing is not recommended as the noodles and tofu can lose their texture.
Perfect Pairings
Pair your miso udon noodle soup with:
-
Side Dishes: Japanese pickles, gyoza (dumplings), or edamame with sea salt.
-
Drinks: A cup of hot green tea or chilled sake pairs beautifully with the savory broth.
-
Dessert: Finish with a light mochi ice cream or matcha cheesecake for a sweet balance.

A: Substitute with thick wheat noodles, soba, or even spaghetti in a pinch. The broth will still shine.
Q: Is miso paste healthy?
A: Yes, miso is rich in probiotics, minerals, and protein. Just be mindful of sodium levels if you’re watching your salt intake.
