FAQs about Beef And Broccoli Lo Mein
Can I use spaghetti instead of lo mein noodles?
Yep, spaghetti works just fine if you can’t find lo mein noodles. Just cook it al dente so it doesn’t go mushy in the stir-fry. The sauce will cling just as well, and no one at the table will complain.
What’s the best cut of beef for lo mein?
Flank steak or sirloin are my go-to choices because they stay tender with quick cooking. Slice it thin against the grain, and you’ll get that perfect, tender bite every time.
How do I make this vegetarian?
Easy fix swap the beef for tofu or even mushrooms. Use soy sauce instead of oyster sauce, and you’ve got a meatless version that’s still loaded with flavor.
Can I make it less salty?
Sure. Go with low-sodium soy sauce and cut back a touch on the oyster sauce. The honey and ginger in the sauce will keep the flavor balanced.
How do I stop my noodles from clumping?
After boiling, toss them with a little sesame oil. That quick trick keeps them silky and ready to stir-fry without turning into a sticky mess.
