Beef and Pepper Stir-Fry FAQ
Can I use frozen beef?
Thaw fully in fridge, then pat super dry to remove excess moisture. Marinate 15 minutes extra since it’s denser. This prevents watery stir-fry and ensures tender results like fresh.
Best beef cuts besides flank?
Skirt steak or thin-sliced ribeye sear beautifully. Avoid chuck; it’s too fatty and toughens. Slice all against the grain for best beef and pepper stir-fry texture.
How to make it gluten-free?
Swap soy sauce for tamari, which is naturally gluten-free. Cornstarch is fine, but check beef broth label. Everything else works perfectly for safe, tasty results.
Scaling for 2 or 6 servings?
Halve or 1.5x ingredients proportionally. For 2, use smaller wok to maintain high heat; for 6, cook in two batches. Rice scales easy too.
Why is my stir-fry watery?
Undried beef or low heat releases moisture, steaming instead of searing. Pat meat dry, preheat wok till smoking, and avoid overcrowding. Boost with cornstarch slurry if needed for glossy fix.
