Instructions

  1. Step 1: Bring a large pot of water to a boil and cook 12 oz fresh udon noodles for 2 minutes until just tender. Drain and set aside.
  2. Step 2: Heat 1 tbsp vegetable oil in a large wok over high heat until shimmering. Add 4 minced garlic cloves and 1/4 tsp red pepper flakes, stir-frying for 30 seconds until fragrant.
  3. Step 3: Add 8 oz sliced shiitake mushrooms and stir-fry for 3-4 minutes until they begin to brown and soften.
  4. Step 4: Toss in 3 halved baby bok choy heads and 1/4 cup water, cover wok and steam for 2 minutes until bok choy is bright green and tender-crisp.
  5. Step 5: Add the drained udon noodles, 3 tbsp soy sauce, and 2 tbsp sesame oil to the wok. Stir-fry everything together for 2 minutes, ensuring noodles are coated and heated through.
  6. Step 6: Remove from heat and garnish with 2 chopped green onions before serving immediately.
