Ingredients
For the steak and vegetables:
- 1 pound flank steak or sirloin, thinly sliced against the grain
- 1 large red bell pepper, sliced into strips
- 1 large green bell pepper, sliced into strips
- 1 medium onion, thinly sliced
- 2 tablespoons vegetable oil or neutral oil
For the sauce and seasoning:
- 3 cloves garlic, minced
- 1/4 cup low-sodium soy sauce
- 2 tablespoons oyster sauce (optional for depth)
- 1 tablespoon rice vinegar or apple cider vinegar
- 1 tablespoon brown sugar or honey
- 1 teaspoon cornstarch mixed with 2 tablespoons water (slurry)
- Salt and pepper to taste
Optional finishing:
- 2 green onions, thinly sliced for garnish
- Sesame seeds for sprinkling
Notes: Trim visible fat from steak and pat dry so it browns. Use low-sodium soy sauce to control salt.
How to Make Pepper Steak with Bell Peppers and Onion
- Prep everything first: slice the steak thin against the grain, cut peppers and onion into strips, mince garlic, and mix the soy sauce, oyster sauce, vinegar, and brown sugar in a small bowl. (Why this matters: mise en place keeps the pan hot and cooking even.)
- Heat a large skillet or wok over medium-high heat and add 1 tablespoon oil. When the oil shimmers, add half the steak in a single layer. Sear 1–2 minutes per side until browned but not fully cooked. Remove to a plate and repeat with the rest of the steak. (Tip: don’t crowd the pan or the meat will steam.)
- Add the remaining 1 tablespoon oil to the pan. Toss in the sliced peppers and onion and stir-fry 3–4 minutes until they soften but stay slightly crisp. Add the minced garlic and cook 30 seconds until fragrant. (Why: peppers should stay crisp-tender for texture.)
- Return the steak to the pan and pour the sauce mix over everything. Stir and let it bubble for a minute so flavors meld.
- Stir in the cornstarch slurry and cook 1–2 minutes until the sauce thickens and coats the meat and vegetables. Taste and adjust with a pinch of salt or a dash more soy sauce if needed.
- Turn off the heat and sprinkle with sliced green onions and sesame seeds if using. Serve hot over rice, noodles, or steamed veggies. (Mini-tip: let the dish rest 1 minute off heat to settle the sauce.)
How to Serve Pepper Steak with Bell Peppers and Onion
- Serve over steamed white or brown rice and spoon the glossy sauce over the top for a cozy plate.
- Toss with wide egg noodles or rice noodles for a stir-fry-style noodle bowl.
- Garnish with green onions and sesame seeds and add a wedge of lime for a bright finish.
How to Store Pepper Steak with Bell Peppers and Onion
- Fridge: Cool to room temperature, transfer to an airtight container, and store up to 3 days.
- Freezer: Place in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm gently in a skillet over medium-low heat with a splash of water or broth to loosen the sauce, or microwave in short bursts, stirring between, until heated through.
Tips to Make Pepper Steak with Bell Peppers and Onion
- Slice the steak thin and against the grain for tender bites.
- Pat the meat dry before searing to get a better browning.
- Don’t overcook the peppers — keep a little crunch for texture contrast.
- Taste the sauce before finishing and adjust sweetness or salt to your liking.
Variation
- Vegetarian: Swap beef for firm tofu or seitan, press and cube tofu, and pan-fry until golden before adding peppers.
- Low-carb: Serve over cauliflower rice or a bed of steamed greens instead of grain.
FAQs
Can I use another cut of beef?
Yes. Sirloin, skirt steak, or flank work well. Choose a thin-slice-friendly cut and cut against the grain for tenderness.
How do I make the sauce less salty?
Use low-sodium soy sauce and taste before adding more. You can balance saltiness with a pinch more brown sugar or a squeeze of vinegar.
Will this freeze well?
Yes. Freeze in a sealed container for up to 2 months. Thaw in the fridge overnight and reheat on the stove with a little water to restore sauce texture.
Can I make this ahead for meal prep?
You can cook everything and store in meal boxes. Reheat gently and add a fresh garnish of green onions for brightness.
