This bell pepper beef recipe transforms simple ingredients into a restaurant-quality dish that balances smoky wok-seared beef with sweet, spicy bell peppers—no takeout needed. After years of testing stir-fry techniques, I’ve perfected a method that delivers caramelized edges and tender beef every time, even in a home kitchen.

The flank steak is non-negotiable here—it’s lean but tender when sliced thin against the grain. Ask your butcher to cut it if you can’t do it yourself; otherwise, freeze it 20 minutes before slicing for easier handling. Costco or Whole Foods usually have pre-sliced stir-fry beef, but fresh is always better. For the bell peppers, mixed colors add visual appeal, but stick to one if you’re in a hurry. Look for firm, glossy peppers—those wrinkly ones have been sitting too long. The garlic and ginger? Freshly grated or minced makes all the difference; jarred minced garlic lacks depth.
No sweet chili sauce? Mix 3 tbsp soy sauce, 1 tbsp honey, and 1 tsp sriracha for a quick substitute. Kikkoman soy sauce is my go-to for balance, but any low-sodium brand works. Sesame oil is purely for aroma—use the toasted kind if you can find it; it’s worth the extra few bucks. Substitute avocado oil if sesame isn’t your thing, but toast it first in a dry pan for 30 seconds to mimic the flavor. The honey in the glaze caramelizes beautifully, so don’t skip it—agave works in a pinch if you’re avoiding sugar. For heat, adjust chili flakes to taste; I like mine with a gentle kick, but add more if you’re feeling bold.
This dish reheats like a dream—30 seconds in the microwave or 2 minutes in a skillet with a splash of water to keep it moist. Store leftovers in an airtight container for 3-4 days, though I’ve never had any last that long. Double the recipe and freeze half for lazy weeknights; it thaws beautifully. The jasmine rice? Cook it ahead and keep warm in a rice cooker—it pairs perfectly with the smoky-sweet beef. Garnish with fresh Thai basil right before serving; regular basil works, but Thai basil’s anise notes elevate the dish. If you’re prepping for a crowd, slice all veggies and measure everything out the night before.

Step-by-step instructions for wok-seared beef with bell peppers
This method delivers perfectly seared beef strips with crisp-tender peppers and a balanced sweet-spicy sauce.
Prepare the Beef and Vegetables
Start by slicing the 1 lb flank steak thinly against the grain into ¼-inch thick strips. This ensures tender bites that cook quickly in the wok. Pat the strips dry with paper towels—moisture prevents proper searing.
Next, slice the 3 whole bell peppers (red, yellow, green) into ¼-inch thick strips, removing stems and seeds. For the aromatics, mince the 4 cloves garlic cloves and grate the 1 tbsp fresh ginger. Keep these ingredients separate until needed—freshly grated ginger and minced garlic release their flavors best at the right moment.
Cook the Jasmine Rice
Rinse the 1.5 cups jasmine rice under cold water until the water runs clear, then drain. Cook according to package instructions, typically using a 1:1.5 rice-to-water ratio and simmering for 15-18 minutes until tender. Fluff with a fork and cover to keep warm—this will serve as the perfect neutral base for the vibrant beef dish.
While the rice cooks, prepare the sauce by combining the 0.5 cup sweet chili sauce, 0.25 cup soy sauce, 1 tbsp honey, and 0.5 tbsp red chili flakes in a small bowl. Stir well and set aside. The sweetness of the honey and chili sauce will complement the smoky beef and crisp peppers beautifully.
Sear the Beef and Vegetables
Heat a wok or large skillet over high heat until smoking, then add 1 tbsp olive oil and 1 tbsp sesame oil. Once the oil shimmers, add the beef strips in a single layer, stirring constantly for 1-2 minutes until they turn deep brown and slightly charred. Remove the beef and set aside—this quick sear locks in juices while creating a caramelized crust.
In the same wok, add another 1 tbsp olive oil if needed, then add the bell pepper strips. Cook for 3-4 minutes, stirring frequently, until they soften slightly but retain their bright color. Add the minced garlic and grated ginger, stirring for 30 seconds until fragrant. The peppers should be tender-crisp, not mushy—this balance is key to the dish's texture.
Combine and Finish
Return the seared beef to the wok, along with the prepared sauce. Toss everything together for 1-2 minutes until the beef is evenly coated and the sauce thickens slightly. The beef should be heated through but still tender—overcooking will make it tough. Season with 1 tsp salt and 0.5 tsp black pepper, adjusting to taste.
Remove from heat and stir in the 0.25 cup chopped fresh Thai basil just before serving. The basil adds a bright, aromatic finish that cuts through the richness of the beef and sweetness of the sauce. Serve immediately over the cooked jasmine rice, garnished with an extra sprinkle of basil if desired.
Pro Tips For Making Bell Pepper Beef
- SEAR FLANK STEAK HOT: I learned this the hard way—flank steak needs screaming heat to develop that crust. Use a cast-iron or heavy skillet, crank it to max, and walk away if it’s not smoking. Two minutes per side max, then pull it out and let it rest. That crust is what keeps the steak juicy when you slice it thin later.
- SLICE PEPPERS LENGTHWISE: Cutting bell peppers into thick strips instead of rings makes this dish actually work. Thick slices caramelize faster and hold up better when stir-frying, so they don’t turn to mush by the time the steak’s done. (Yes, even if it looks like you’re making a weird pepper steak salad—trust me.)
- GINGER SMASH DON’T CHOP: After burning three batches of ginger, I finally figured out: smash it with the flat side of your knife instead of mincing. This releases more flavor without turning your pan into a smoke bomb. A teaspoon of smashed ginger is enough—don’t overdo it, or the sweet chili sauce will get overpowered.
- REST STEAK UNDER FOIL: Skip the plate and tent that seared flank steak with foil for 5-10 minutes. This keeps it warm while you finish the peppers and sauce, and it guarantees slices that don’t fall apart when you plate them. (Your future self will curse you if you skip this.)
Health benefits of this recipe

Frequently asked questions
Can I substitute flank steak with another cut of beef?
For best results, use sirloin, ribeye, or skirt steak—all work well when sliced thin against the grain. Avoid tougher cuts like chuck roast, as they won't tenderize properly in the quick sear. If using pre-sliced stir-fry beef from the grocery store, check the package for cooking times—it may require slightly less searing.
How do I prevent the beef from becoming chewy?
Slice the beef thinly against the grain (¼-inch thick) and sear it over high heat for just 1-2 minutes—any longer risks toughness. Pat the strips dry before cooking to ensure proper browning. For extra tenderness, marinate the beef in 1 tbsp soy sauce and 1 tsp honey for 15 minutes before searing.
What if I don’t have sweet chili sauce?
Mix 3 tbsp soy sauce + 1 tbsp honey + 1 tsp sriracha for a quick substitute. For extra depth, add ½ tsp fish sauce or a splash of lime juice. The key is balancing sweet, savory, and a touch of heat—adjust to taste!
Can I make this dish ahead of time?
Yes! Cook the beef and peppers fully, then store in an airtight container for 3-4 days. Reheat in a skillet with a splash of water for 2-3 minutes to restore moisture. The rice should be cooked fresh to avoid sogginess. For freezing, portion the beef mixture and freeze for up to 2 months—thaw overnight before reheating.
Why are my bell peppers still crunchy after cooking?
Bell peppers need 3-4 minutes of cooking to soften slightly while keeping texture. If they're still too firm, slice them thinner (⅛-inch) or add ½ tsp baking soda to the cooking water (for roasted peppers) to speed up tenderness. Stir-frying at high heat helps—don't overcrowd the pan!
