There’s something deeply comforting about the sizzle of steak hitting a hot pan—the way the aroma fills the kitchen, promising a meal that’s both hearty and vibrant. This Pepper Steak with Bell Peppers and Onion is one of those dishes that never fails to make me feel at home, no matter how chaotic the day has been. Inspired by the quick stir-fries my mom used to whip up on busy weeknights, it’s a dish that balances tender beef, sweet peppers, and just the right touch of savory sauce. Whether you’re craving a cozy dinner or need a crowd-pleaser for guests, this recipe is a winner.

Ingredients You’ll Need

Let’s gather everything first—trust me, it makes the cooking process so much smoother. Here’s what you’ll need:

• 1 lb flank steak or sirloin – Thinly sliced against the grain for maximum tenderness. Flank steak is my go-to, but sirloin works beautifully too.
• 2 bell peppers – I love using a mix of red and green for color and sweetness, but any variety will do.
• 1 large onion – Yellow or white, sliced into thin strips. They caramelize so nicely!
• 3 cloves garlic – Minced. Because what’s a stir-fry without garlic?
• 2 tbsp soy sauce – For that umami depth. Low-sodium works if you’re watching salt.
• 1 tbsp oyster sauce – The secret ingredient that adds richness. Worcestershire sauce is a decent substitute.
• 1 tsp brown sugar – Just a hint to balance the savory notes.
• 1/2 tsp black pepper – Freshly cracked is best.
• 1 tbsp cornstarch – To thicken the sauce slightly.
• 2 tbsp vegetable oil – For stir-frying. Peanut oil adds great flavor too.

Step-by-Step Instructions

Now, let’s bring this dish to life. Follow these steps, and you’ll have a restaurant-worthy pepper steak in no time:

1. Prep the steak: Slice the steak thinly against the grain—this ensures every bite is tender. Toss it with 1 tbsp soy sauce and cornstarch, then let it sit for 10 minutes. This quick marinade works wonders!
2. Sear the steak: Heat 1 tbsp oil in a large skillet or wok over high heat. Add the steak in a single layer (work in batches if needed) and sear for 1–2 minutes per side until browned but not fully cooked. Transfer to a plate.
3. Cook the veggies: In the same pan, add the remaining oil. Toss in the onions and bell peppers, stirring frequently for 3–4 minutes until they start to soften. Add the garlic and cook for another 30 seconds—just until fragrant.
4. Bring it all together: Return the steak to the pan, along with the remaining soy sauce, oyster sauce, brown sugar, and black pepper. Stir-fry for another 2 minutes until everything is glossy and well-coated. If the sauce thickens too much, a splash of water loosens it perfectly.

Tip: Don’t overcrowd the pan when searing the steak—this ensures a good sear instead of steaming. And if you love a bit of heat, a pinch of red pepper flakes adds a lovely kick!

Pro Tips, Variations, and Substitutions

Making the perfect pepper steak is all about balancing flavors and textures. Here are some expert tips and creative twists to make this dish your own:

• Slice against the grain: For tender bites, always cut your steak thinly against the grain before cooking.
• Marinate for extra flavor: Let the steak sit in the sauce for 30 minutes before cooking to deepen the flavors.
• Vegetable variations: Swap bell peppers for mushrooms, snap peas, or even zucchini for a different twist.
• Protein alternatives: Chicken, shrimp, or tofu work beautifully if you’re not in the mood for beef.
• Spice it up: Add a pinch of red pepper flakes or a drizzle of sriracha for those who love heat.

What to Serve With Pepper Steak

This vibrant dish pairs wonderfully with so many sides! Here are our favorites:

Storage and Reheating Tips

Leftovers? No problem! Here’s how to keep your pepper steak tasting fresh:

• Refrigerator: Store in an airtight container for up to 3 days.
• Freezer: Freeze portions for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheating: Warm gently in a skillet over medium heat with a splash of water or broth to refresh the sauce. Microwave works too – cover and heat in 30-second intervals, stirring between.
• Pro tip: The flavors often taste even better the next day as the ingredients have more time to meld!

Frequently Asked Questions

Can I use a different cut of beef?
Absolutely! While flank or sirloin work best, you can use skirt steak, ribeye, or even tenderloin. Just adjust cooking times as thicker cuts may need longer.

Is this dish gluten-free?
It can be! Simply substitute the soy sauce with tamari or coconut aminos, and ensure your other ingredients are gluten-free.

How do I prevent my peppers from getting mushy?
Add them towards the end of cooking – they only need 2-3 minutes to soften slightly while retaining their crispness and bright color.

Can I make this in advance?
Yes! Prep all ingredients separately and store in the fridge. When ready to eat, simply stir-fry everything together – it will take just minutes to cook.
