I’ve been making this pepper steak on busy weeknights for years — thin strips of sirloin seared hot, bright bell pepper, and a glossy sauce that coats every forkful. It’s simple, fast, and reliably satisfying, which is exactly why people search for “best pepper steak” when they want a restaurant-style stir-fry at home. If you like bold, savory flavors with a touch of sweetness and a silky sauce, this is the one to master. For a similar take and more ideas, you can compare techniques with this Best Pepper Steak Recipe.
Why you’ll love this dish
This pepper steak is built for weeknights: it cooks in under 20 minutes, uses pantry-friendly sauces, and stretches a modest amount of beef into leftovers that taste even better the next day. The thin sirloin slices stay tender because we briefly marinate them in soy and cornstarch, then flash-sear over high heat — the result is meat that’s savory, slightly caramelized, and coated in a glossy sauce. It’s also flexible: swap peppers, switch broths, or turn it vegetarian with extra-firm tofu.
“Dinner on the table in 20 minutes, with restaurant-level flavor — this pepper steak is my go-to when I want something that tastes indulgent but is actually easy.” — Home cook review
How this recipe comes together
- Marinate: Toss thin sirloin with soy and cornstarch to flavor and velvet the meat.
- Sear: Heat oil until shimmering and sear beef fast in batches to avoid steaming.
- Vegetables: Quickly sauté sliced bell pepper and garlic until just tender-crisp.
- Sauce: Deglaze the pan with beef broth, add oyster sauce and sugar, then reduce to concentrate flavor.
- Finish: Return beef to the pan, coat with sauce, adjust seasoning, and garnish with green onions and sesame seeds.
What you’ll need
- 1.5 pounds beef sirloin, thinly sliced (tender and flavorful — slice across the grain)
- 2 tablespoons soy sauce (adds umami; use low-sodium or tamari for gluten-free)
- 1 tablespoon cornstarch (helps thicken the sauce and velvet the beef)
- 2 tablespoons vegetable oil, divided (use canola or another high smoke-point oil)
- 1 bell pepper, sliced red or yellow (for color and sweetness; green works too)
- 2 cloves garlic, minced (fresh for best aroma)
- 0.5 cup beef broth (keeps the dish moist; chicken or vegetable broth works as a substitute)
- 1 tablespoon oyster sauce (enhances depth — for vegetarian, try hoisin or mushroom sauce)
- 1 teaspoon sugar (balances the savory)
- Salt and pepper, to taste (season carefully; soy already adds salt)
- 2 green onions, chopped for garnish (adds freshness)
- 1 teaspoon sesame seeds (optional for crunch)
Notes: If your sirloin isn’t pre-sliced, freeze for 20–30 minutes to firm it up, then slice thinly across the grain. If you’re avoiding shellfish, replace oyster sauce with an equal amount of hoisin or add a splash of extra soy plus a pinch of mushroom powder.

Step-by-step instructions
Preparation
- Slice the sirloin thinly across the grain into 1/8–1/4-inch strips.
- In a bowl, combine the beef, 2 tbsp soy sauce, and 1 tbsp cornstarch. Toss until evenly coated. Let sit 10 minutes while you prep vegetables.
- Slice the bell pepper into 1/4-inch strips and mince the garlic. Mix the beef broth, oyster sauce, and sugar in a small cup.
Cooking
- Heat 1 tablespoon vegetable oil in a large skillet or wok over high heat until shimmering. Add half the beef in a single layer and sear 30–45 seconds without stirring, then flip and cook another 20–30 seconds until browned but still tender. Remove to a plate; repeat with remaining beef using the other tablespoon of oil. (Work in batches to keep the pan hot.)
- Lower heat to medium-high. Add the sliced bell pepper and stir-fry 2–3 minutes until it’s just tender but still bright. Add garlic and cook 20–30 seconds until fragrant.
- Pour the beef broth mixture into the pan, scraping up any brown bits. Bring to a simmer and cook 1–2 minutes to reduce slightly.
- Return the beef and any accumulated juices to the pan. Toss to coat in the sauce and heat through, about 30–45 seconds. Taste and season with salt and pepper if needed. If you prefer a thicker sauce, mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir in, cooking another 30 seconds until glossy.
- Remove from heat and garnish with chopped green onions and sesame seeds.
Best ways to enjoy it
Serve pepper steak over steamed jasmine rice or sticky rice to soak up the sauce. For a lower-carb option, spoon it over cauliflower rice or serve alongside sautéed bok choy and noodles. For family-style plating, place the stir-fry in a shallow bowl and sprinkle with extra green onions and a wedge of lime (optional) for a bright finish.
Pairings:
- Rice or Chinese-style noodles (lo mein or rice noodles)
- Stir-fried greens such as bok choy, gai lan, or snow peas
- Light beer, fruity Riesling, or a slightly tannic red if you prefer wine
Storage and reheating tips
Cool leftovers quickly and refrigerate within two hours. Store in an airtight container for up to 3–4 days. Reheat gently in a skillet over medium heat with a splash of broth to revive the sauce and prevent drying; microwaving works but can toughen the beef, so heat in short bursts and stir. To freeze: cool completely, place in a freezer-safe container, and freeze for up to 2 months. Thaw in the fridge overnight before reheating.
Food safety note: because the beef slices are thin, they cook quickly — ensure they reach a safe internal temperature (145°F for whole cuts). If anyone in your household requires well-done meat, cook the slices a little longer and slice slightly thicker to avoid overcooking edges.
Pro chef tips
- Velveting: The cornstarch + soy marinate both seasons the beef and creates a thin coating that keeps juices sealed during high-heat searing. Don’t skip it.
- High heat and batches: Sear meat in batches so the pan temperature stays high; crowded pans steam the beef.
- Texture control: Cook peppers until just tender-crisp; they’ll retain sweetness and color. Overcooking makes them soft and dull.
- Sauce shine: If your sauce looks dull, a quick cornstarch slurry (cold water + cornstarch) will bring a glossy finish.
- Make-ahead: Slice the beef and prep veggies ahead to shave minutes off weeknight cooking. If you’re serving this at a cookout, pair it with a smoky side like Anastasia’s Best Ever Baked Beans to round the menu.
Creative twists
- Garlic-forward: Double the garlic and add a splash of toasted sesame oil at the end for a bolder aroma.
- Spice it up: Add a teaspoon of chili garlic sauce or fresh sliced chilies while stir-frying peppers for heat.
- Vegetarian: Use pressed, extra-firm tofu or seitan in place of beef; coat and sear the same way. Swap oyster sauce for mushroom-based vegetarian “oyster” sauce.
- Citrus lift: Finish with a teaspoon of rice vinegar or a squeeze of lime for brightness.
- Southwest twist: Swap oyster sauce for a touch of Worcestershire and add cumin for an unexpected, smoky riff.
Common questions
Q: How long does this take from start to finish?
A: Active cook time is about 12–15 minutes; prep (slicing and mixing) takes another 10 minutes. Plan for 20–30 minutes total.
Q: Can I use a different cut of beef?
A: Yes — flank steak or skirt steak work if sliced very thin across the grain. Ribeye is richer but cooks similarly; strip or sirloin are the easiest to slice and best for quick searing.
Q: Is oyster sauce necessary?
A: Oyster sauce adds depth and a slightly savory-sweet umami note. If you need a substitute, hoisin plus a dash of soy can work; mushroom-based sauces also offer a vegetarian option.
Q: Will the cornstarch make the beef gummy?
A: If you use the right amount (1 tbsp for this quantity) and don’t over-mix, it will create a velvety coating rather than gummy texture. Mix just until combined and sear quickly.
Q: How can I keep the peppers crunchy?
A: Stir-fry over high heat and remove the pan from heat as soon as they’re tender-crisp. Overcrowding the pan or cooking too long will soften them.
