Step‑by‑Step Instructions for Miso Udon Noodle Soup with Teriyaki Mushrooms
Step 1: Prepare Mushrooms
Begin by soaking the dried shiitake mushrooms overnight in a bowl of water until rehydrated and plump. In a skillet over medium heat, add 2 teaspoons of neutral oil or vegan butter, then sauté thinly sliced king oyster and rehydrated shiitake mushrooms for about 5 minutes until golden. Drizzle in 1 tablespoon of mirin, 1 tablespoon of sake, 1 tablespoon of soy sauce, and 1.5 teaspoons of sugar, cooking until everything is well-coated and glazed, about 3 more minutes. Set aside to cool.
Step 2: Cook Udon Noodles
In a large pot, bring water to a rolling boil. Add 2 servings of udon noodles and cook according to the package instructions, usually about 8-10 minutes, until they are chewy yet tender. Once done, drain the noodles through a colander and place them evenly in serving bowls, ready to be bathed in the flavorful broth.
Step 3: Make the Broth
In a medium saucepan, heat 1 tablespoon of vegan butter or sesame oil over medium heat. Add 2 minced garlic cloves, sautéing for about 1 minute until fragrant. Gradually stir in 1 tablespoon of nut butter, 2 cups of mushroom or vegetable broth, and 2 cups of plain unsweetened soy milk. Mix until combined, then add 1 tablespoon of miso paste, cover, and bring to a gentle boil. Let it simmer for 5 minutes, adjusting seasoning with salt if desired.
Step 4: Assemble the Soup
Carefully pour the hot broth over the cooked udon noodles in each bowl, ensuring the noodles are fully immersed. Top the soup with the sautéed teriyaki mushrooms, sprigs of spring onions, and a drizzle of layu for a spicy kick. Allow the soup to sit for a minute, letting the flavors meld beautifully before serving up this comforting bowl of Miso Udon Noodle Soup with Teriyaki Mushrooms.

Miso Udon Noodle Soup with Teriyaki Mushrooms Recipe FAQs
What type of mushrooms should I use for the teriyaki topping?
Absolutely! While the recipe calls for king oyster and rehydrated shiitake mushrooms, feel free to use any mushrooms you prefer, such as cremini or portobello for a deeper flavor. Just ensure they are fresh and firm, avoiding any with dark spots or excessive moisture.
How should I store any leftover soup?
To keep your Miso Udon Noodle Soup delicious, store it in an airtight container in the fridge for up to 3 days. If you’ve made a large batch, it’s best to keep the noodles and broth separate to preserve their textures. The broth can also be frozen for up to 3 months; just be sure to cool it completely before transferring to a freezer-safe container.
Can I freeze the soup? If so, how?
Yes, you can definitely freeze the soup! To do this, simply separate the udon noodles from the broth. Allow the broth to cool, then pour it into freezer-safe bags or containers. It’s best to freeze the broth without the noodles to avoid mushiness. When you’re ready to enjoy, thaw the broth in the fridge overnight and reheat on the stovetop before adding freshly cooked noodles.
What if my broth ends up too salty or bland?
Don’t worry; we’ve all been there! If your broth turns out too salty, you can balance it by adding a splash of extra plant-based milk, or adding a bit of water to dilute it. For blandness, boost the flavor with a splash more of soy sauce or allow it to simmer longer to enhance the depth. Tasting as you go is key for achieving the perfect flavor!
Are there any allergy considerations I should be aware of?
Yes! This recipe contains soy (in the form of soy sauce and soy milk), making it unsuitable for those with soy allergies. Additionally, check the labels on your broth and any nut butters for potential allergens. For a nut-free version, replace the nut butter in the broth with additional sesame oil or omit it altogether.
