Choosing the Right Ingredients: My Best Friend Tips
Let’s talk ingredients, because that’s where the magic truly begins! For the beef, flank steak is my go-to because it’s flavorful and slices beautifully. But if you can’t find it, skirt steak or even sirloin will work in a pinch. Just remember to slice against the grain for maximum tenderness. As for the noodles, fresh lo mein noodles are the best for that authentic texture, but dried work perfectly well too. Just be sure to cook them according to the package directions – nobody wants mushy noodles!
And speaking of substitutions, if you’re looking for Garlic Butter Beef Bites you could even use those as the beef option. It’s a great way to change up the flavor, while keeping all the same great tastes and textures.
Step-by-Step Instructions
Step 1: Marinate the Beef
- In a medium bowl, whisk together soy sauce, cornstarch, rice wine vinegar, sesame oil, ginger, and pepper.
- Add the sliced beef to the marinade, tossing to coat evenly.
- Cover the bowl and refrigerate for at least 30 minutes, or up to 2 hours. This allows the flavors to meld and the beef to tenderize.
Step 2: Cook the Noodles
- Cook the lo mein noodles according to package directions. Usually, this involves boiling them in salted water until they’re just al dente.
- Drain the noodles well and toss with a little sesame oil to prevent sticking. Set aside.
Step 3: Stir-Fry the Beef and Vegetables
- Heat 1 tablespoon of vegetable oil in a large wok or skillet over high heat.
- Add the marinated beef (discarding any excess marinade) and stir-fry until browned on all sides, about 2-3 minutes. Remove the beef from the wok and set aside.
- Add the remaining 1 tablespoon of vegetable oil to the wok. Add the onion, garlic, and ginger and stir-fry until fragrant, about 1 minute.
- Add the broccoli florets and stir-fry for 2-3 minutes, until they start to turn bright green and slightly tender.
Step 4: Make the Sauce and Combine
- In a small bowl, whisk together beef broth, soy sauce, oyster sauce, brown sugar, sesame oil, and red pepper flakes (if using).
- Pour the sauce over the broccoli and bring to a simmer. Cook for 1-2 minutes, until the sauce thickens slightly.
- Return the cooked beef to the wok. Add the cooked lo mein noodles.
- Toss everything together until the noodles are evenly coated with the sauce and the beef and broccoli are heated through.
Step 5: Serve and Garnish
- Serve the Beef And Broccoli Lo Mein Noodles immediately.
- Garnish with sesame seeds and chopped green onions, if desired.
- Enjoy!
Common Mistakes and How to Avoid Them (Trust Me, I’ve Been There!)
Okay, let’s be real. Stir-frying can be intimidating! The biggest mistake people make is overcrowding the pan. If you try to cook too much beef or broccoli at once, you’ll end up steaming it instead of getting that beautiful, slightly charred flavor. Cook in batches if necessary. Also, don’t be afraid to crank up the heat! A hot wok is essential for a good stir-fry. And for the love of all that is delicious, don’t overcook the broccoli! You want it to be crisp-tender, not mushy.
Speaking of amazing noodle dishes, have you ever tried Garlic Butter Chicken Noodles? It’s another one of my go-to simple dinner ideas for family easy nights. Or if you’re in the mood for something cheesy, Garlic Parmesan Pasta is always a winner. For something a little different and great for meat lunch ideas, consider trying Philly Cheesesteak Bowls. It is a unique twist that will give you energy to get through the day! And if you loved the beef marinade from this recipe, you should definitely try Garlic Butter Beef Bites sometime!
Tips for Next-Level Lo Mein Noodles

- Veggies galore! Feel free to add other vegetables like bell peppers, carrots, or snow peas.
- Protein power! Shrimp, chicken, or tofu would also be delicious in this dish.
- Make it ahead! You can marinate the beef and chop the vegetables ahead of time to save time on busy weeknights.
- Use high quality soy sauce! This is a key ingredient, so splurging for the good stuff is worth it.
Making It Your Own: Variations and Adaptations
This recipe is your blank canvas! Don’t be afraid to experiment and make it your own. If you’re not a fan of broccoli (gasp!), you could easily substitute it with other vegetables like snow peas, bell peppers, or even bok choy. For a vegetarian option, try using tofu or mushrooms instead of beef. And if you’re watching your sodium intake, you can use low-sodium soy sauce. The possibilities are endless!
