Start by bringing a large pot of salted water to a boil. Add the 7 oz of dry Lo Mein noodles and cook according to the package instructions until al dente. Drain the noodles and set them aside, tossing them with a bit of oil to prevent sticking.
While the noodles are cooking, slice the garlic, bok choy, and red bell pepper. Make sure your shrimp is ready to go—peeled and deveined.
In a large skillet or wok, heat 2 tablespoons of cooking oil over medium-high heat. Once the oil is hot, add the minced garlic and sauté for about 30 seconds until fragrant.
Add the shrimp to the skillet and cook until they turn pink and are opaque, approximately 2-3 minutes. Remove the shrimp from the skillet and set aside.
In the same skillet, add the sliced bok choy and red bell pepper. Stir-fry for about 3-4 minutes until the vegetables are tender yet still crisp.
Return the cooked shrimp to the skillet with the vegetables. Add the cooked Lo Mein noodles, oyster sauce, soy sauce, dark soy sauce, and chicken broth. Toss everything together to ensure the noodles are well coated and heated through, about 2-3 minutes.
Drizzle 1 teaspoon of sesame oil over the dish, tossing to combine. This adds a lovely aromatic quality that ties everything together.
Serve the Shrimp Lo Mein hot, garnished with a sprinkle of white sesame seeds if desired. Enjoy immediately for the best texture and flavor!
