Gather all your ingredients to ensure a smooth cooking process. Slice the mushrooms, mince the garlic, and prep any additional veggies.

Cook the chow mein noodles according to package instructions, about 5 minutes. Drain and set aside.

In a large skillet or wok, heat 2 tablespoons of vegetable oil over medium-high heat until shimmering.

Add the sliced mushrooms and minced garlic to the hot oil; sauté for 3-4 minutes until tender.

Incorporate the cooked chow mein noodles, soy sauce, sugar, and a pinch of white pepper; toss vigorously.

Stir in the chopped bok choy and bean sprouts, cooking for another 2-3 minutes until bok choy wilts.

If sticking, add a splash of water while stirring continuously to keep the noodles moist.

Drizzle sesame oil over the chow mein and sprinkle with sesame seeds. Toss to combine and serve hot.
