Chinese Pepper Steak Stir-Fry is vibrant and bold with tender steak and crisp peppers coming together in a naturally savory sauce. I make this dish whenever I want something fast and satisfying that still feels a bit special and full of color.
The first time I made this for my family everyone went back for seconds and even my picky eaters wanted leftovers for lunch the next day.
Ingredients
- Beef top sirloin steak: because it cooks quickly and stays tender when sliced across the grain Look for bright red meat with a little marbling for best flavor
- Soy sauce: brings salty umami to the sauce Choose low sodium if you prefer less salt
- White sugar: balances the saltiness and gives a classic Chinese restaurant style glaze
- Cornstarch: thickens the sauce and makes the beef silky Make sure it is fresh and lump free
- Ground ginger: adds warmth and depth Use a good quality ground spice for best flavor
- Vegetable oil: is perfect for high heat stir frying I prefer neutral oils like canola or sunflower for clean taste
- Red onion: gives bite and a slight sweetness Choose firm onions with shiny skin for crunch
- Green bell pepper: adds color and a crisp fresh note Pick peppers with glossy skin and no soft spots
- Tomatoes: create a bright accent and a touch of tang Go for tomatoes that feel heavy for their size and have a fresh scent

I always look forward to the juicy bursts of tomato in every bite it was my grandmother’s secret touch that I have kept in every version I make My kids say the sweet sauce is their favorite part and ask for extra to spoon over rice
