Frequently Asked Questions (FAQs)
Can I use a different cut of beef?
Yes. Sirloin, ribeye, or skirt steak also work well. Always slice thinly against the grain for tenderness.
Can I make this dish vegetarian?
Yes. Replace beef with firm tofu, tempeh, or seitan and use vegetable broth instead of beef broth.
Can I make it gluten-free?
Yes. Use tamari or a gluten-free soy sauce and ensure oyster sauce is gluten-free.
Can I prepare it ahead of time?
Yes. Slice and marinate the beef up to 24 hours in advance. Vegetables can also be prepped ahead.
Can I add other vegetables?
Yes. Broccoli, snow peas, carrots, or mushrooms can be added. Adjust cooking times for different vegetables to keep them crisp tender.
Can I make the sauce spicier?
Yes. Add red pepper flakes, sriracha, or fresh chili peppers to taste.
Can I double the recipe?
Yes. Cook beef and vegetables in batches to avoid overcrowding the pan, which can cause steaming instead of searing.
Can I use frozen bell peppers?
Yes, but thaw and pat dry first. Cook briefly to prevent excess water from making the sauce thin.
Can I freeze this dish?
Yes, but bell peppers may become soft after freezing. Freeze the beef and sauce separately for best results.
How do I keep the beef tender?
Marinate it properly and avoid overcooking. Stir-fry quickly over high heat for best texture.
