Instructions

  1. Step 1: Bring a large pot of water to boil and cook 12 oz fresh udon noodles for 2-3 minutes until just tender. Drain and rinse under cold water to stop cooking.
  2. Step 2: Heat 2 tbsp sesame oil in a large wok or skillet over medium-high heat until shimmering. Add 4 minced garlic cloves and 2 tbsp minced fresh ginger, stir-frying for 30 seconds until fragrant but not browned.
  3. Step 3: Add 1 sliced medium red bell pepper and 1 julienned medium carrot to the wok. Stir-fry for 3-4 minutes until vegetables are crisp-tender.
  4. Step 4: Add drained udon noodles, 3 tbsp soy sauce, 1 tbsp sriracha sauce, and 1 tsp brown sugar to the wok. Toss everything together and cook for 2-3 minutes until noodles are heated through and sauce evenly coats them.
  5. Step 5: Remove from heat and stir in 3 sliced green onions. Sprinkle with 1 tbsp toasted sesame seeds before serving.
