This skillet pepper steak has saved countless weeknight dinners at my house when time is tight but I still want something flavorful. Inspired by Chinese-American cuisine, this adaptation delivers all the taste with minimal effort, ready in just 15 minutes with barely any cleanup afterward.
I first created this recipe during a particularly hectic work week when takeout was tempting but my budget disagreed. Now it has become our Tuesday night tradition when we need something quick but refuse to compromise on flavor.
Ingredients
- Top round beef: sliced thinly for quick cooking and tender results
- Kosher salt and freshly ground black pepper: essential for proper seasoning that brings out the beef flavor
- Peanut oil: provides a higher smoke point ideal for stir frying but any neutral oil works well
- Soy sauce: adds umami depth and savory notes to the sauce
- Rice wine vinegar: brings brightness and acidity to balance the richness
- Crushed red pepper flakes: add customizable heat adjust according to your spice preference
- Colorful bell peppers: red, yellow, green, and orange offer sweet flavor and vibrant presentation
- Fresh garlic cloves: minced finely add aromatic punch and complexity
- Scallions: provide a mild onion flavor and fresh green garnish
- Sesame seeds: create textural contrast and nutty flavor finish
Step-by-Step Instructions
- Season the Beef:
- Sprinkle kosher salt and freshly ground black pepper generously over your thinly sliced beef. The proper seasoning at this stage builds the foundation of flavor. Heat your first tablespoon of oil until it shimmers in the pan before adding the beef.
- Quick Sear the Meat:
- Add the seasoned beef to the hot skillet in a single layer if possible. Allow it to sear for about 30 seconds before stirring to develop color. Continue stir frying for just about 90 seconds more until the exterior browns but the interior remains slightly undercooked. This prevents the beef from becoming tough during the final cooking stage.
- Create the Sauce Mixture:
- Transfer your partially cooked beef to a bowl and immediately add soy sauce, rice wine vinegar, and red pepper flakes. Toss thoroughly to coat every piece ensuring the hot beef absorbs the flavors. This brief marinating time while you cook the vegetables infuses the meat with extra flavor.
- Cook the Peppers:
- Using the same unwashed skillet, add your remaining tablespoon of oil and heat it over medium heat. Add all your colorful peppers, spreading them in an even layer. Let them cook relatively undisturbed for the first minute to develop some slight charring then toss occasionally for about three more minutes until they just begin to soften but still maintain some crispness.
- Combine and Finish:
- Push your peppers to one side of the skillet creating room to return your beef and its accumulated sauce to the pan. Let the beef cook for two minutes to finish cooking through. Add minced garlic to the peppers, not directly to the hot oil to prevent burning, and cook one minute more until fragrant. Gently combine everything tossing briefly to integrate all components.

I discovered the magic of using all four colored bell peppers by accident when cleaning out my produce drawer one night. The combination not only creates a stunning presentation but also offers subtle flavor variations between the peppers that make each bite slightly different from the last.
Meal Prep Magic
This pepper steak reheats beautifully making it perfect for meal prep. Store in airtight containers in the refrigerator for up to three days. The flavors actually intensify overnight which many of my friends report makes the leftovers even better than the freshly made version. I recommend slightly undercooking the peppers if you know you'll be reheating later.
Perfect Pairings
While traditional white rice makes an excellent base for this dish consider branching out. Cauliflower rice keeps things low carb while quinoa adds extra protein and nutrients. For a more substantial meal serve with a side of steamed edamame or a simple cucumber salad dressed with rice vinegar and a touch of sesame oil to complement the Asian flavors of the main dish.
Quick Substitutions
No top round beef available? Flank steak or sirloin work wonderfully with the same slicing technique. Vegetarians can swap in firm tofu or tempeh pressed well to remove excess moisture before cooking. If you cannot find rice wine vinegar white wine vinegar with a pinch of sugar makes a reasonable alternative. Feel free to use just one or two types of bell peppers if that is what you have on hand the recipe remains delicious even with less variety.

Frequently Asked Questions About Recipes
- → Can I use a different cut of beef for this pepper steak?
Yes, you can substitute flank steak, sirloin, or ribeye. The key is slicing the meat very thinly against the grain to ensure tenderness. If using a tougher cut, consider marinating it longer in the soy mixture before cooking.
- → How can I make this dish spicier or milder?
Adjust the heat by increasing or decreasing the crushed red pepper flakes. For extra spice, add a diced jalapeño or serrano pepper. For a milder version, reduce the pepper flakes to 1/2 teaspoon or omit them entirely.
- → What can I serve with skillet pepper steak?
White rice is the classic pairing, but it's also delicious with brown rice, cauliflower rice (for a low-carb option), or noodles. A simple side of steamed broccoli or a cucumber salad would complement the meal nicely.
- → Can I make this dish ahead of time?
While best enjoyed fresh, you can prepare the components ahead of time. Slice the beef and peppers and store separately in the refrigerator. The dish reheats well in a skillet for quick leftovers, though the peppers may soften slightly.
- → Is there a vegetarian alternative to this dish?
Absolutely! Substitute the beef with extra-firm tofu (pressed and cubed), tempeh, or seitan. For a hearty vegetable version, try using portobello mushrooms cut into strips, which provide a meaty texture and umami flavor.
- → What substitutes work for rice wine vinegar?
If rice wine vinegar isn't available, apple cider vinegar or white wine vinegar can work as substitutes. For a slightly different flavor profile, you could also use mirin (Japanese sweet rice wine) with a splash of regular vinegar.
