Pepper Steak with Onion
A Chinese-American style pepper steak with sliced beef, red and green bell peppers, onion wedges, and a savory soy sauce glaze.
Pepper steak with onion is a familiar Chinese-American takeout-style dinner that maps well to Western supermarkets. Beef, bell peppers, onions, soy sauce, garlic, and ginger are easy to buy and easy to understand.
This recipe overlaps with beef and bell pepper stir-fry, but it targets a different search phrase and leans into visible onion wedges and a slightly glossier sauce. It is mild, rice-friendly, and practical for families.
Bell peppers and onions give the beef enough sweetness and crunch that the sauce can stay simple.
Before You Start
Large skillet or wok, Mixing bowl, Small bowl
- beef
- bell pepper
- onion
- garlic
- soy sauce
- sugar
- Read all steps once before heating the pan, pot, or skillet. Chinese home cooking often moves quickly after the oil or broth is hot.
- Measure sauces, chop aromatics, and place ingredients near the stove before you start cooking.
- For stir-fries and skillet dishes, keep ingredients separated by cooking order so nothing overcooks while you look for the next item.
- If serving with rice, start the rice first so the hot topping is ready at the same time.
Success check: Taste before serving: the dish should be hot, seasoned enough to eat with rice or noodles, and adjusted gently if needed.
Ingredients
- beef: 450 g / 1 lb flank steak, sirloin, or stir-fry beef.
- bell pepper: 2 large red and green.
- onion: 1 medium.
- garlic: 2 cloves.
- ginger: 1 tsp grated (optional).
- soy sauce: 2 tbsp.
- oyster sauce: 1 tbsp (optional).
- rice vinegar: 1 tsp (optional).
- sugar: 1 tsp.
- cornstarch: 2 tsp.
- neutral oil: 1 tbsp.
- rice: Cooked rice, for serving (optional).
Steps
- Slice beef across the grain
Cut the beef into thin strips across the visible muscle lines. Thin strips cook quickly and stay tender. If using pre-sliced stir-fry beef, pat it dry and separate the pieces before marinating.
- Marinate beef and mix sauce
Toss beef with a little soy sauce, cornstarch, and water until lightly coated. In a separate bowl, combine soy sauce, oyster sauce if using, rice vinegar, sugar, and 3 tablespoons water. Slice peppers and onion into even strips.
- Sear beef first
Heat oil in a large skillet over medium-high heat. Add beef in one layer and cook just until browned at the edges. Move it to a plate before it is fully cooked; it will finish later with the sauce.
- Cook peppers and onion
Add peppers and onion to the pan. Stir-fry for 2 to 3 minutes until they brighten and begin to soften. Keep them moving, but let them touch the hot pan enough to pick up a little color.
- Add garlic, ginger, and sauce
Add garlic and ginger and stir for 20 seconds. Return beef and pour in the sauce. Toss while it bubbles and coats everything. Add a spoonful of water if the sauce thickens before the vegetables are coated.
- Serve while beef is tender
Turn off the heat when the beef is just cooked through and the peppers are still crisp-tender. Serve with rice if using. Avoid long simmering, which makes thin beef strips chewy.
Western Grocery Notes
- Use a mix of red and green bell peppers for color, but one color is fine.
- Flank steak, sirloin, or pre-sliced stir-fry beef all work.
- Cut onion into wedges so it stays visible and does not disappear into the sauce.
Substitutions
- Use chicken or tofu instead of beef if needed.
- Use broccoli, mushrooms, or snap peas instead of one bell pepper.
- Use hoisin plus soy sauce if oyster sauce is unavailable.
Ingredient Alternatives
-
Beef
Provides the classic steak strips.
Alternatives: Flank steak, Sirloin, Skirt steak. Freeze the beef for 15 minutes if you need help slicing it thinly.
-
Bell peppers
Add color, crunch, and sweetness.
Alternatives: Red bell pepper, Green bell pepper, Sweet mini peppers. Use at least one bright pepper so the dish looks distinct on the page.
-
Onion
Adds sweetness and the familiar pepper steak texture.
Alternatives: Yellow onion, White onion, Red onion. Cut into wedges so it stays crisp-tender and visible.
Cook Better Next Time
- Cook peppers and onions hot and fast so they stay crisp.
- Sear beef separately if your skillet is small.
- Let the sauce bubble for 30 to 60 seconds so cornstarch activates and coats the beef.
FAQ
