Step‑by‑Step Instructions for Miso Udon Noodle Soup
Step 1: Prepare the Mushrooms
If you’re using dried shiitake mushrooms, start by soaking them in warm water for about 20 minutes or until rehydrated. Once softened, drain the mushrooms and slice them thinly. This step enhances the deep umami flavor of the soup. Fresh mushrooms can also be used; just clean and slice them before proceeding.
Step 2: Cook Udon Noodles
Bring a pot of water to a rolling boil and add the udon noodles according to the package instructions. Typically, this takes about 5–7 minutes. Once cooked, drain the noodles and rinse them under cold water to halt the cooking process. This will prevent them from becoming overly soft in your Miso Udon Noodle Soup.
Step 3: Sauté Teriyaki Mushrooms
In a skillet over medium heat, add 1-2 tablespoons of neutral oil or vegan butter. Once hot, add the sliced shiitake and king oyster mushrooms. Sauté for about 5–7 minutes until they’re browned and glossy. Pour in mirin, soy sauce, and a sprinkle of sugar, stirring until the mushrooms are well-coated and the glaze thickens slightly; set aside.
Step 4: Make the Broth
In a medium pot, heat 1 tablespoon of vegan butter or sesame oil over medium heat, adding minced garlic as it starts to melt. Sauté for about 1–2 minutes until fragrant, ensuring it doesn’t brown. Then, stir in your plain nut butter or sesame paste, vegetable broth, and soy/oat milk. Mix until blended, then add miso paste and soy sauce, simmering for about 10-12 minutes on low heat.
Step 5: Combine and Serve
In serving bowls, add a portion of the udon noodles. Carefully ladle the hot miso broth over the noodles, ensuring they’re fully submerged. Top with the sautéed teriyaki mushrooms and garnish with chopped spring onions or green onions for freshness. Serve your comforting Miso Udon Noodle Soup hot, inviting everyone to enjoy this delicious meal!
