Last Saturday I fired up my Blackstone on the deck and started prepping some fresh lo mein noodles. My friend Mike wandered over, half curious and half skeptical. “What’s that?” he asked, eyeing the pile of noodles.
“Blackstone beef lo mein,” I replied, sliding marinated flank steak onto the hot zone. The sear was perfect — that audible crackle that means flavor is building fast.
Mike laughed and said, “You can’t make Chinese food on a griddle, man.”
Twenty minutes later he was on his third plate, asking if I had the recipe written down. That’s what proper Blackstone beef lo mein does: it converts skeptics and has people coming back for seconds before they’ve finished their first bite.

How to Make Blackstone Beef Lo Mein
Step 1: Prep the Beef
For easier, cleaner slices, chill the flank steak in the freezer for about 20 minutes. Slice thinly against the grain. Toss the strips with cornstarch, soy sauce, oil, and baking soda. Let the meat rest 15–30 minutes while you prep the other ingredients.
Step 2: Make the Sauce
Whisk the sauce ingredients together, making sure the cornstarch dissolves fully to avoid lumps. Keep the sauce warm in a small pan on the cooler zone of your griddle.
Step 3: Noodle Prep
Cook noodles per package directions but stop 1–2 minutes early so they remain al dente. Drain, rinse with cold water to halt cooking, and toss with about 1 teaspoon oil to prevent sticking.
Step 4: Set Up Griddle Zones
Preheat the Blackstone into three zones: high (around 450°F) for searing, medium (about 375°F) for combining, and low (about 300°F) for holding. Using zones helps you control cooking speed and texture.
Step 5: Cook the Beef
Add 1 tablespoon oil to the high-heat zone. Spread the marinated beef in a single layer and let it sear undisturbed for about 30 seconds. Stir-fry 1–2 minutes until it’s roughly 75% cooked, then move the beef to the low zone to stay warm.
Step 6: Aromatics and Vegetables
Add another tablespoon of oil to the high zone, toss in garlic and ginger and stir for 30 seconds until fragrant. Add onion and carrot first and cook about 1 minute, then add bell peppers and cook 1–2 minutes until tender-crisp.
Step 7: Combine Everything
Move the vegetables to the medium zone. Add the noodles and one-third of the warm sauce, tossing to separate and coat. Return the beef, add the remaining sauce gradually, and toss until evenly coated and glossy.
Step 8: Finish and Serve
Add green onions in the final 30 seconds and give everything one last toss. The noodles should be heated through with a shiny, restaurant-style finish. Serve immediately.
Variations & Substitutions
If you can’t find flank steak, sirloin works well when sliced thin. Chicken thighs are a tasty alternative. Swap or add vegetables like snap peas, mushrooms, or baby corn — add firmer vegetables first and delicate ones last. For extra crunch, stir in bean sprouts during the final minute of cooking.
Serving Suggestions
This lo mein stands on its own but pairs nicely with steamed jasmine rice, fried rice, or a simple vegetable side like garlic bok choy or sesame green beans. Jasmine tea or a cold lager complement the savory-sweet flavors well.
Storage Instructions
Store leftovers in the refrigerator for 3–4 days. Reheat on the griddle with a splash of water for best results — it revives the texture and flavor. You can also prep components in advance: marinate the beef up to 24 hours and keep the sauce refrigerated for several days.
FAQ
Q: Can I use a wok instead of a Blackstone? A: Yes. A wok works well; just cook in smaller batches and use the highest heat your stove allows to mimic the searing effect.
Q: What if I can’t find fresh lo mein noodles? A: Dried egg noodles are fine — cook to al dente and rinse cold. In a pinch, even spaghetti can substitute.
Q: How important is the baking soda? A: It’s key to velveting the beef and achieving a tender, restaurant-style texture. Skipping it still yields a tasty stir-fry, but the beef won’t be quite as tender.
Q: Can I prep ahead for a party? A: Absolutely. Marinate the beef, make the sauce, and prep vegetables beforehand. The final cook takes only minutes, so you’ll have hot, fresh lo mein when guests arrive.
Q: My noodles stick together. What should I do? A: Rinse them with cold water after cooking and toss with a little oil immediately. Avoid letting them sit too long before adding to the griddle.
Q: Best way to slice flank steak? A: Cut against the grain to shorten muscle fibers, which makes the beef feel more tender. The brief freezer trick helps you slice thin, even strips.
Overall, this Blackstone beef lo mein is my go-to when I want impressive, flavorful food without a lot of fuss. With straightforward techniques and the right heat control, you can produce restaurant-quality lo mein that will have friends and family convinced you’re a grill master.
