Ingredients You’ll Need

Each ingredient in this Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe plays a crucial role: from the tender steak to the vibrant peppers, and the sauce that ties it all together. When shopping, I recommend picking the freshest bell peppers available—they make all the difference in both taste and presentation.

• Flank steak: Look for a skirt or flank steak with good marbling but not too fatty. Thinly slicing against the grain keeps it tender.
• Red, green, and yellow bell peppers: Using all three adds beautiful color and a subtle mix of sweetness and crunch.
• Onion: I prefer yellow or white onions for a mild bite that caramelizes slightly when cooked.
• Vegetable oil: Neutral oils with a high smoke point work best for stir-frying—think canola or sunflower.
• Soy sauce: Opt for low-sodium if you’re watching salt, but regular works perfectly for full flavor.
• Oyster sauce: Adds that rich, umami depth. It’s worth seeking out if you want authentic taste.
• Cornstarch: Helps thicken the sauce and gives it that silky coating on everything.
• Water: Just enough to blend with the cornstarch and balance the sauce.
• Rice vinegar: Brings acidity and brightness.
• Honey or brown sugar: Adds a touch of sweetness to round out the flavors.
• Garlic: Fresh minced garlic keeps the dish aromatic and punchy.
• Fresh ginger: Grated ginger adds warmth and a slightly spicy zing.
• Sesame oil: A little goes a long way for that signature nutty aroma.
• Red pepper flakes (optional): For a subtle heat boost if you like a bit of spice.

Variations

I like to play around with this Pepper Steak Stir-Fry with Bell Peppers and Onion Recipe depending on what’s in season or what mood I’m in. You can easily swap in different proteins or veggies to keep things fresh and cater to your tastes.

• Protein swap: Sometimes I use thinly sliced chicken breast or tofu instead—both soak up the sauce beautifully.
• Veggie switch-up: Broccoli florets, snap peas, or mushrooms are great alternatives or additions for varied textures.
• Heat factor: When I want it spicier, I toss in fresh sliced chilies or a drizzle of chili garlic sauce.
• Make it gluten-free: Just swap out soy sauce for tamari and double-check your oyster sauce, and you’re good to go.

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

Step 1: Slice the meat and veggies thoughtfully

The secret to tender steak here is slicing the flank steak thinly and against the grain—you’ll find the meat easier to chew and much more tender in every bite. Similarly, slice the bell peppers and onion into relatively thin strips so everything cooks evenly and quickly. I usually use a sharp chef’s knife and take my time here, as this prep sets the tone for the whole dish.

Step 2: Whisk up the flavor-packed sauce

In a small bowl, I mix soy sauce, oyster sauce, cornstarch, water, rice vinegar, honey, minced garlic, grated ginger, and sesame oil until smooth. This sauce not only flavors the steak and veggies but also creates that luscious glossy coating you’ll love. If you want some heat, stir in the red pepper flakes at this point.

Step 3: Stir-fry everything at high heat

Heat your vegetable oil in a large wok or skillet over medium-high heat. First, toss in the steak strips and stir-fry for about 2-3 minutes until they start to brown but aren’t fully cooked yet. Remove the steak and set it aside to keep it from overcooking. Next, add the sliced bell peppers and onion to the pan and stir-fry until slightly tender but still crisp, usually 3-4 minutes.

Return the steak to the pan, pour in the sauce mixture, and stir continuously until the sauce thickens and everything is well coated—should take about 1-2 minutes. Be careful not to overcook here; you want the steak juicy and the veggies vibrant.

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

Garnishes

I love sprinkling toasted sesame seeds and fresh chopped green onions on top—adds a nice crunch and fresh contrast. A sprinkle of chopped cilantro or a squeeze of lime juice can brighten it up even more. If you like heat, a few extra red pepper flakes or a drizzle of sriracha work wonders here.

Side Dishes

This Pepper Steak Stir-Fry with Bell Peppers and Onion is fantastic over steamed jasmine rice or flaky white rice to soak up that sauce. For swapping in something lighter, cauliflower rice or even noodles (like soba or udon) also pair beautifully. When I’m looking to keep it low-carb, I pile the stir-fry onto a bed of sautéed greens or serve alongside roasted vegetables.

Creative Ways to Present

For a fun dinner party, I’ve served this stir-fry family-style in a big colorful bowl with chopsticks and small dipping bowls of extra sauce and crushed peanuts on the side. Another time, I rolled the stir-fry into warm lettuce cups for a light, hands-on appetizer vibe. Experimenting with presentation can make this simple dish feel extra special.

Make Ahead and Storage

Storing Leftovers

I store leftover Pepper Steak Stir-Fry with Bell Peppers and Onion in an airtight container in the fridge for up to 3 days. It holds up well because of the thick sauce, which helps keep the steak moist. Just be sure to cool it to room temperature before refrigerating to maintain texture.

Freezing

I’ve frozen this stir-fry a couple of times, and while it’s best fresh, it still tastes good after freezing. To freeze, pop cooled leftovers into a freezer-safe bag or container and try to use it within 2 months. When thawed, the texture of the peppers gets softer, so it’s great if you plan to reheat it in a hot skillet.

Reheating

Reheat your leftovers gently in a skillet over medium heat, stirring frequently to warm everything through without drying it out. Adding a splash of water or broth can revive the sauce and keep the steak tender. I avoid microwaving since it can make the peppers limp, but if you’re short on time, just cover the dish to trap moisture.
