Instructions

  1. Step 1: Bring a large pot of water to a boil. Add 12 oz fresh udon noodles and cook for 2-3 minutes until just tender. Drain and rinse under cold water to stop cooking.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over medium-high heat. Add 3 minced garlic cloves and 1 tbsp grated fresh ginger; stir-fry for 30 seconds until fragrant.
  3. Step 3: Add 1 cup sliced shiitake mushrooms and 3 cups halved baby bok choy. Stir-fry for 4-5 minutes until mushrooms are tender and bok choy leaves are wilted but stems remain crisp.
  4. Step 4: Add cooked udon noodles to the wok. Pour in 3 tbsp low sodium soy sauce and 1 tsp sesame oil. Toss everything together and stir-fry for 2 more minutes until noodles are heated through and sauce coats all ingredients.
  5. Step 5: Remove from heat and garnish with 2 sliced green onions and 1 tbsp toasted sesame seeds before serving.
