Tips, variations, and serving ideas
- Freeze the flank steak for 15–20 minutes before slicing; many stir-fry guides recommend this to make cutting thin strips easier.
- Add a splash of oyster sauce or a pinch of sugar if you prefer a slightly richer, more “takeout-style” glaze, as seen in some Chinese-American pepper steak recipes.
- Swap part of the flank steak for thinly sliced chicken or pork for a mixed stir-fry variation, or add mushrooms for extra umami.
Storage and FAQs
How do I store leftovers?
Cool, then refrigerate in an airtight container for up to 3–4 days. Stir-fried beef and peppers reheat well in a skillet over medium heat or briefly in the microwave.
Can I make this ahead?
You can slice the steak and vegetables and mix the marinade ahead, then cook everything quickly just before serving—a strategy often recommended for stir-fries to keep textures crisp and fresh.
Sizzling Chinese Pepper Steak with Onions delivers tender strips of beef, crisp vegetables, and big flavor in under 30 minutes, making it a reliable go-to when you want a takeout-style dinner without leaving home.
