While the noodles cook, combine the soy sauce, oyster sauce, hoisin sauce, sesame oil, brown sugar, rice vinegar, black pepper, and red pepper flakes in a small bowl.
Whisk until the sugar is incorporated.
Set the sauce aside.
Having it ready before you start stir-frying makes the rest of the recipe move quickly.
3. Brown the Ground Beef
Heat a large skillet or wok over medium-high heat.
Add the vegetable oil, followed by the ground beef.
Cook until browned, breaking it apart with a spoon or spatula as it cooks.
If there's a large amount of excess grease, carefully drain some of it.
4. Add the Aromatics
Add the minced garlic and grated ginger.
Cook for about 30–60 seconds, stirring constantly.
You want the garlic and ginger to become fragrant without burning.
5. Cook the Vegetables
Add the carrots, bell pepper, and mushrooms.
Stir-fry for several minutes until the vegetables are tender-crisp.
Don't cook them until they're completely soft. A little crunch gives the finished lo mein much better texture.
6. Add the Noodles
Add the cooked noodles to the skillet.
Pour the sauce over everything.
Use tongs to toss the noodles, beef, vegetables, and sauce together until everything is evenly coated.
Cook for another 2–3 minutes, allowing the sauce to warm through and cling to the noodles.
7. Finish With Green Onions
Turn off the heat and add the sliced green onions.
Give everything one final toss.
Serve immediately.
Tips for the Best Beef Lo Mein
Don't Overcook the Noodles
Slightly undercooked noodles are ideal because they'll continue cooking when tossed with the hot sauce and beef.
Use a Large Skillet
A crowded pan makes stir-frying difficult.
If your skillet isn't large enough, work in batches or use a wok.
Cook Over Relatively High Heat
Stir-frying works best when the pan is hot.
Have all your ingredients prepared before you begin because the cooking process moves quickly.
Keep the Vegetables Crisp
Cut vegetables into similar-sized pieces so they cook evenly.
Avoid cooking them until they're mushy.
Adjust the Sauce to Your Taste
Prefer sweeter lo mein? Add another teaspoon of brown sugar.
Want more heat? Increase the crushed red pepper.
Prefer a stronger savory flavor? Add a small splash of soy sauce.
Easy Variations
Add More Vegetables
Almost any stir-fry-friendly vegetable can work.
Try:
- Broccoli
- Snow peas
- Bok choy
- Cabbage
- Bean sprouts
- Zucchini
- Spinach
Make It Spicy
Add chili crisp, sriracha, crushed red pepper flakes, or sliced fresh chilies.
Swap the Protein
Ground beef can easily be replaced with:
- Ground chicken

- Thinly sliced steak
- Cooked shrimp
- Shredded chicken
Add a Crunchy Topping
Finish each bowl with chopped peanuts, cashews, sesame seeds, or crispy fried onions.
What Kind of Noodles Can You Use?
Traditional lo mein uses Chinese egg noodles, but you don't need to make a special trip to the store if you don't have them.
Depending on what's available, you can use:
- Spaghetti
- Linguine
- Ramen noodles
- Chinese egg noodles
- Fresh wheat noodles
- Other sturdy Asian-style noodles
The texture will vary, but the savory sauce and beef will still make a delicious meal.
What to Serve With Ground Beef Lo Mein
Because this dish already includes meat, noodles, and vegetables, it can easily stand alone as a complete meal.
If you're serving a larger dinner, pair it with:
- Egg rolls
- Dumplings
- Spring rolls
- Steamed broccoli
- Asian cucumber salad
- Fried or steamed wontons
A simple side can turn it into a fun takeout-style dinner at home.
How to Store Leftovers
Allow leftovers to cool appropriately before transferring them to an airtight container.
Refrigerate and enjoy within a few days.
When reheating, add a small splash of water or broth if the noodles seem dry. Warm them in a skillet or microwave until heated through.
The noodles may absorb some of the sauce while sitting, so a little extra liquid can help restore their texture.
Can You Freeze Ground Beef Lo Mein?
You can freeze it, although the noodles and vegetables may become somewhat softer after thawing.
For the best texture, make only as much as you'll eat within a few days.
If you do freeze leftovers, cool them completely before placing them in a freezer-safe container.
Frequently Asked Questions
Can I make lo mein without oyster sauce?
Yes. Hoisin sauce can provide some of the sweetness and savory depth, although the final flavor will be different. You can also use a vegetarian oyster-style sauce if preferred.
Can I use frozen vegetables?
Absolutely. Frozen stir-fry vegetables are a convenient shortcut. Add them directly to the skillet and cook until heated through and any excess moisture has evaporated.
How do I keep lo mein from becoming soggy?
Don't overcook the noodles, drain them well, and avoid adding excessive sauce. Keeping the vegetables crisp also helps maintain a better overall texture.
Can I make this recipe ahead?
Yes. Cooked lo mein stores well in the refrigerator and makes an excellent meal-prep lunch. For the freshest texture, slightly undercook the noodles if you know you'll be reheating the dish later.
What makes lo mein different from chow mein?
Both dishes use noodles and stir-frying techniques, but preparation and noodle styles can vary by region and restaurant. Lo mein is commonly associated with boiled noodles that are tossed with the other ingredients and sauce.
