Description

This Creamy Mushroom Udon is a vegan and dairy-free Japanese-inspired noodle dish. It features tender udon noodles enveloped in a rich and creamy umami-packed sauce made from plant-based milk, miso, and a medley of sautéed shiitake and shimeji mushrooms. A comforting meal perfect for a quick yet nourishing dinner that’s both lighter and full of flavor.


Ingredients

NOODLES

  • 2 servings frozen udon or other wheat noodles of choice

MUSHROOM UDON

  • 2 tbsp vegan butter
  • 1 green onion, white and green parts separated
  • 4 cloves garlic, minced
  • 8 shiitake mushrooms, sliced (or other mushrooms of choice)
  • 5.2 oz shimeji mushrooms, base chopped then separated (1 pack)
  • 2 tbsp vegetable broth
  • ½ tsp sugar (optional, for balance)
  • ¾ cup unsweetened oat milk or soy milk
  • ½ tbsp white miso paste
  • 12 tbsp soy sauce, to taste
  • 2 tsp dark soy sauce (optional, for colour and extra umami)
  • Freshly ground black pepper

SLURRY

  • 1 tsp cornstarch
  • 2 tsp room-temperature water

TO FINISH

  • Green parts of green onion, for garnish


Instructions

  1. Prepare Noodles: If using frozen udon, place noodles in a microwave-safe bowl, cover, and microwave on high for about 60 seconds until separated. Alternatively, briefly place them in boiling water just until loosened, being careful not to overcook. For vacuum-sealed cooked udon, soak in hot water or follow package instructions, then separate and drain. Prepare any other noodles according to package directions until chewy or al dente. Set aside.
  2. Heat Pan and Sauté Aromatics: Heat a large wok or skillet over medium heat. Once hot, melt the vegan butter. Add the white parts of the green onion and cook for 1 minute. Add the minced garlic and cook until fragrant, about 30 seconds.
  3. Cook Mushrooms: Add all the mushrooms to the pan and toss to coat in the butter, garlic, and green onions. Increase heat to medium-high and leave mushrooms mostly undisturbed for 2–3 minutes to sear. Stir and let the other sides brown lightly to develop deep flavor.
  4. Deglaze and Simmer: Add the vegetable broth and optional sugar, letting the mixture simmer briefly to deglaze the pan and round out the flavors.
  5. Add Sauce Ingredients: Pour in the plant-based milk, white miso paste, soy sauce, and dark soy sauce if using. Stir well until the miso dissolves completely.
  6. Simmer Sauce: Bring the sauce to a gentle boil, then reduce heat to low to maintain a gentle simmer.
  7. Add Udon and Season: Add the prepared udon noodles to the skillet and toss to coat evenly in the creamy mushroom sauce. Season with freshly ground black pepper to taste.
  8. Thicken Sauce: Mix the cornstarch and water to create a slurry. Pour the slurry into the pan over medium-low heat and stir gently until the sauce thickens to a creamy consistency.
  9. Adjust Seasoning and Finish: Taste the noodles and adjust seasoning with more soy sauce or salt if needed. Turn off the heat—the sauce will continue to thicken slightly.
  10. Garnish and Serve: Mix in or garnish with the green parts of the green onion. Serve the creamy mushroom udon hot and enjoy immediately.

Notes

  • You can substitute udon noodles with other wheat noodles of choice but aim for thick, chewy noodles for the best texture.
  • For a nuttier creaminess, oat milk is preferred, but soy milk is a great alternative.
  • The sugar is optional but helps balance the umami and acidity of the miso sauce.
  • Be careful not to overcook the noodles to maintain a pleasantly chewy texture.
  • Dark soy sauce is optional but adds color and deepen umami flavor, so it can be skipped if unavailable.
