Pepper Steak with Bell Peppers and Onion – A Flavorful Takeout-Style Classic

Pepper Steak with Bell Peppers and Onion is one of those dishes that feels nostalgic, bold, and comforting all at once. With roots in American Chinese cuisine, it was inspired by traditional Cantonese stir-fries but adapted with heartier cuts of beef and more robust sauces.

In this dish, thin slices of beef are seared to perfection, then stir-fried with crisp bell peppers and tender onions. It’s all tossed in a deeply savory, slightly sweet sauce made with soy, garlic, and ginger. The final result is glossy, fragrant, and irresistibly satisfying — perfect for scooping over rice or noodles.

What makes pepper steak truly special is its balance of texture and flavor: juicy beef, crunchy peppers, sweet caramelized onions, and that glossy sauce that coats every bite.

Ingredients Overview

Each ingredient has a purpose, contributing to the texture, depth, and balance of flavors in the dish. Here’s what you’ll need and how to get the most from each component.

• Beef (Flank, Sirloin, or Skirt Steak): Thinly sliced against the grain for tenderness. These cuts cook quickly and absorb marinades beautifully. Flank steak is the most traditional option for pepper steak.

• Bell Peppers (Red, Green, Yellow): Use a colorful mix for both sweetness and visual appeal. Red peppers are the sweetest, while green peppers have a mild bitterness that balances the dish.

• Yellow or White Onion: Sliced thick for texture. As they cook, they soften and develop a subtle sweetness that complements the sauce.

• Garlic and Fresh Ginger: Essential aromatics that infuse the oil and bring the whole dish to life. Always use fresh for best flavor.

• Soy Sauce (Light and Dark): Light soy sauce provides salinity while dark soy sauce adds color and umami. For gluten-free, substitute with tamari.

• Oyster Sauce: Adds richness and slightly sweet depth to the sauce. A vegetarian mushroom-based version can be used if needed.

• Shaoxing Wine or Dry Sherry: Optional but highly recommended for authentic flavor. Adds a slight tang and complexity. Omit or use broth if avoiding alcohol.

• Cornstarch: Used both in marinating the beef and thickening the sauce. It gives the beef a silky, tender coating.

• Beef Broth: Forms the base of the sauce. Use low-sodium to control saltiness.

• Sugar (Optional): Just a small amount rounds out the flavors, especially if you’re using mostly green peppers.

• Sesame Oil: Added at the end for nutty aroma. Don’t use it to cook — it burns easily.

• Neutral Oil: Use a high-smoke-point oil like canola or avocado oil for searing.

Step-by-Step Instructions

1. Slice and Marinate the Beef
   Cut the steak into thin strips against the grain. In a bowl, combine the beef with 1 tablespoon soy sauce, 1 teaspoon cornstarch, and a splash of sesame oil. Let it marinate for at least 15 minutes. This helps tenderize the meat and create that velvety stir-fry texture.

2. Make the Sauce
   In a small bowl, whisk together:

   • 2 tablespoons light soy sauce

   • 1 tablespoon dark soy sauce

   • 1 tablespoon oyster sauce

   • ½ cup beef broth

   • 1 tablespoon Shaoxing wine (or broth)

   • 1 teaspoon sugar

   • 1 teaspoon cornstarch

   Stir until smooth and set aside.

3. Prep Vegetables
   Slice bell peppers and onion into ½-inch strips. Mince garlic and grate the ginger. Keep everything nearby — stir-frying moves quickly.

4. Sear the Beef
   Heat 1–2 tablespoons of neutral oil in a large skillet or wok over high heat. Add the beef in a single layer (work in batches if needed). Let it sear for 1–2 minutes without stirring to develop a crust, then flip and cook until no longer pink. Remove and set aside.

5. Sauté the Vegetables
   In the same pan, add a little more oil if necessary. Stir-fry the onion for 1 minute, then add garlic and ginger. After 30 seconds, toss in the bell peppers. Cook for 2–3 minutes until the veggies are tender-crisp.

6. Combine and Sauce
   Return the beef to the pan. Stir the sauce again (cornstarch may have settled), then pour it over everything. Toss well to coat, letting it simmer for 1–2 minutes until the sauce thickens and glazes the beef and vegetables.

7. Finish with Sesame Oil
   Turn off the heat and drizzle with a small amount of sesame oil for aroma. Give everything one last toss before serving.

Tips, Variations & Substitutions

• Cut Against the Grain: This ensures the beef stays tender. If unsure, look for the grain lines in the meat and slice perpendicular to them.

• Tenderize Tough Cuts: If using a tougher cut, marinate with a little baking soda for 20 minutes before rinsing and marinating in the sauce.

• Make It Spicy: Add red chili flakes, sliced Thai chilies, or a dash of chili garlic sauce.

• Vegetarian Option: Use sliced portobello mushrooms or seitan in place of beef and swap oyster sauce for a mushroom-based stir-fry sauce.

• Low-Carb Version: Serve over cauliflower rice or spiralized zucchini noodles.

• Gluten-Free: Use tamari and ensure all sauces (especially oyster sauce) are labeled gluten-free.

• More Veggies? Add broccoli florets, snap peas, or baby corn for extra crunch and variety.

FAQs

Q1: What’s the best beef cut for pepper steak?
Flank steak is a popular choice due to its tenderness when sliced thinly against the grain. Sirloin or skirt steak also works well. Avoid stew meat or chuck unless it’s very thinly sliced and tenderized.

Q2: Can I use frozen bell peppers?
Yes, but be aware that frozen peppers release moisture and can become softer. Thaw and pat dry before stir-frying for best results.

Q3: How do I slice beef thinly at home?
Freeze the steak for 30 minutes before slicing. This firms it up and makes it easier to cut into thin, even slices.

Q4: How do I prevent the beef from becoming tough?
Slice against the grain, marinate with cornstarch, and avoid overcooking. High heat and quick cooking are key.

Q5: Can I make the sauce ahead of time?
Absolutely. Mix the sauce in advance and store in the fridge for up to 3 days. Stir before using, as cornstarch may settle.

Q6: How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 4 days. Reheat in a skillet or microwave. Add a splash of water to loosen the sauce if needed.

Q7: What if I don’t have oyster sauce?
Substitute with hoisin sauce for sweetness or a mix of soy sauce and a pinch of brown sugar. Mushroom stir-fry sauce is a great vegetarian alternative.
