How to Make Beef and Broccoli Lo Mein
Step 1 – Marinate the Beef
In a bowl, combine soy sauce, oyster sauce, cornstarch, sesame oil, and black pepper. Add the sliced beef, mix well, and let marinate for 15–60 minutes in the fridge.
Step 2 – Cook the Noodles
Boil noodles according to package directions until al dente. Drain, rinse with cold water, and set aside.
Step 3 – Make the Sauce
In a small bowl, whisk together all the sauce ingredients until smooth and the sugar dissolves.
Step 4 – Cook the Beef
Heat 1 tablespoon of oil in a wok or large skillet over medium-high heat. Add the marinated beef and stir-fry for 2–3 minutes until just cooked through. Remove from the wok and set aside.
Step 5 – Stir-Fry the Vegetables
Add another tablespoon of oil to the wok. Stir-fry the broccoli and carrots for about 2 minutes. Add 2 tablespoons of water, cover, and steam for 1–2 minutes until tender-crisp.
Step 6 – Add the Aromatics
Toss in the red bell pepper, garlic, and ginger. Stir-fry for another minute until fragrant.
Step 7 – Combine Everything
Return the beef to the wok. Pour in the sauce and bring it to a gentle simmer until it thickens slightly, about 1 minute. Add the noodles and toss until evenly coated in the glossy sauce.
Step 8 – Garnish and Serve
Top with sliced green onions and sesame seeds, then serve hot. Enjoy your homemade lo mein straight from the wok!
Tips for the Best Lo Mein
- Prep Before You Cook: Have all your ingredients ready — stir-frying moves fast!
- Slice Beef Thinly: For the most tender results, freeze the beef for 15–20 minutes before slicing.
- Don’t Over-Marinate: Too long in soy sauce can make the beef mushy.
- Perfect Sauce Thickness: It should coat the back of a spoon — not too runny, not too thick.
- Cook Veggies by Hardness: Start with broccoli and carrots, then add softer veggies like peppers later.
- Noodle Swaps: Try udon, rice noodles, or even zucchini noodles for a lighter option.
- Flavor Boosters: Add mushrooms, bean sprouts, or Chinese cabbage for extra texture and taste.
How to Store and Reheat
To Store:
Let leftovers cool completely, then store in an airtight container in the fridge for up to 3–4 days.
To Reheat:
Warm in a skillet or wok over medium heat with a splash of water or oil for 3–4 minutes, stirring often. You can also microwave with a damp paper towel for 2–3 minutes, stirring halfway.
