Ingredients You’ll Need

Each ingredient in this Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe plays a part in creating a harmony of tastes and textures. The steak gives it meaty richness, the bell peppers add crunch and sweetness, and the sauce ties everything together with that irresistible savory kick. When shopping, look for fresh, firm bell peppers and a good-quality flank steak for the best results.

• Flank steak: Choose a thin cut for easy slicing and quick cooking; slicing against the grain ensures tenderness.
• Red, green, and yellow bell peppers: Using a mix adds vibrant color and a sweet, crisp contrast to the beef.
• Onion: A medium yellow or white onion brings just the right amount of sweetness and depth.
• Vegetable oil: Good for high-heat stir-frying without burning.
• Soy sauce: Adds saltiness and umami; low-sodium works well if you watch salt intake.
• Oyster sauce: Brings a rich, slightly sweet depth—don’t skip it if you can help it!
• Cornstarch and water: Mix these to thicken the sauce beautifully without clumps.
• Rice vinegar: Adds brightness and cuts through the richness.
• Honey or brown sugar: Balances the savory flavors with a hint of sweetness.
• Garlic and fresh ginger: Essential aromatics that pack punch and zest.
• Sesame oil: Use a small amount for that signature nutty flavor.
• Optional red pepper flakes: If you like a little heat, they add a nice kick without overpowering.

Variations

I love customizing this Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe depending on what’s in my fridge or my mood. Sometimes I swap out the flank steak for chicken or tofu, and it turns out just as delicious. Feel free to experiment to make this truly your own.

• Protein swap: Using chicken breast or thighs works well; for vegetarians, marinated tofu holds up nicely and soaks in the sauce.
• Veggie add-ins: I’ve tossed in snap peas or mushrooms to mix texture and round out the dish.
• Less sugar or no oyster sauce: To make it lighter or vegan, substitute oyster sauce for mushroom sauce or a splash of soy sauce and skip the honey.
• Spice level: I sometimes add fresh chili or increase red pepper flakes when I want more heat.

How to Make Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe

Step 1: Prep Your Ingredients Carefully

This step is a game-changer—slice your flank steak thinly against the grain to keep it tender; I like to freeze it for about 20 minutes first to make slicing super easy. Cut your bell peppers into thin strips, roughly the same size so everything cooks evenly. Don’t skimp on mincing the garlic and grating the ginger fresh—you’ll notice the flavor difference immediately. Trust me, good prep saves time and results in a restaurant-quality stir-fry at home.

Step 2: Whisk Together the Sauce

Mix soy sauce, oyster sauce, rice vinegar, honey, sesame oil, garlic, ginger, and red pepper flakes (if using) in a bowl. In a separate small cup, stir together cornstarch and water until smooth. Pour this into the sauce mixture and stir well. This is your magic combo that will thicken up and coat the steak and veggies perfectly.

Step 3: Stir-Fry the Steak

Heat vegetable oil in a large skillet or wok over high heat until shimmering. Add the sliced steak in a single layer, cooking quickly without overcrowding so it sears nicely—about 1-2 minutes per side. Remove and set aside; this quick sear locks in the juices. If your pan gets crowded, do this in batches for best results.

Step 4: Cook the Vegetables

In the same pan, add a little more oil if needed. Toss in the onions and stir-fry for about 2 minutes until they start to soften. Then add the bell peppers and continue stir-frying until the peppers are tender-crisp—usually another 3-4 minutes. You want to keep that satisfying crunch, so watch them closely.

Step 5: Combine Everything with the Sauce

Return the steak to the pan with the veggies. Give your sauce a quick stir (to make sure the cornstarch hasn’t settled) and pour it over everything. Stir constantly as it cooks for 1-2 minutes until the sauce thickens and beautifully coats every piece. That moment is pure kitchen magic, and you’ll know you nailed the Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe.

How to Serve Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe

Garnishes

I always sprinkle toasted sesame seeds and chopped green onions on top for a fresh crunch and a bit of nutty flavor. Sometimes I add a few sprigs of fresh cilantro if I have it around—adds a lovely bright note. These little extras make the dish feel extra special without any fuss.

Side Dishes

Serve this Pepper Steak Stir-Fry with steamed jasmine or brown rice to soak up the delicious sauce. If you want to keep it low-carb, cauliflower rice is a great alternative that still lets the stir-fry shine. I’ve also paired it with simple garlic noodles on occasion, and that combo is unbeatable.

Creative Ways to Present

One time, I served this stir-fry in small bowls lined with fresh lettuce leaves, turning it into a fun wrap-style meal that guests loved. For a date night, plating it over a bed of stir-fried noodles with a drizzle of chili oil adds that restaurant-level polish. Presentation can be as simple or as fancy as you like!

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge for up to 3 days. The veggies keep some of their crunch, and the steak stays tender, making it a perfect next-day lunch or quick dinner solution. Just make sure you cool it completely before sealing to avoid sogginess.

Freezing

I’ve frozen this Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe successfully by portioning it into freezer-safe containers. Just be aware the bell peppers lose some crispness after thawing, so it’s best reserved for cooked dishes or heating with rice. It still tastes fantastic when reheated though!

Reheating

Reheat leftovers gently in a skillet over medium heat, adding a splash of water or broth if the sauce has thickened too much. Avoid microwaving if you can, as this tends to make the veggies mushy. Keeping a close eye while warming helps maintain that fresh stir-fry texture you love.
