Pepper steak recipe easy: How to Tenderize Flank Steak

Make tender pepper steak in 25 minutes by velveting flank steak with cornstarch and soy sauce before cooking. This Chinese restaurant technique transforms tough beef into silky, melt-in-your-mouth strips perfect for stir-fry.

You bought flank steak on sale. You sliced it, cooked it, and bit into rubber. The beef was so tough you could barely chew it. You ended up ordering Chinese takeout and vowed never to cook steak again.

The problem wasn’t the steak—it was the technique. Flank steak is a lean, flavorful cut, but it’s naturally tough. Chinese restaurants don’t have magic beef. They use a technique called “velveting” that coats meat in cornstarch, tenderizing it and creating that signature silky texture.

This pepper steak recipe easy enough for weeknights teaches you the velveting technique that turns bargain beef into restaurant-quality tender strips. When you’re looking for more Chinese takeout recipes you can master at home, our ultimate guide to quick and easy meals has dozens more flavor-packed solutions.

The game-changer? A 10-minute cornstarch marinade is the difference between chewy beef and tender, velvety pepper steak.

Put down that takeout menu. We’re making pepper steak so tender, you’ll think it came from your favorite Chinese restaurant.

Why This Pepper Steak is a Weeknight Lifesaver

• 25 minutes total — faster than delivery
• Velveting technique — makes cheap beef taste expensive
• One pan — everything cooks in the same wok or skillet
• Budget-friendly — flank steak costs less than ribeye
• High protein — 30g protein per serving
• Colorful vegetables — bell peppers add nutrition and crunch
• Leftovers are great — tastes even better the next day

Ingredients & Swaps

The Basics: Flank steak (affordable and flavorful), bell peppers (for color and crunch), soy sauce (salty umami), cornstarch (the tenderizer), and basic aromatics (garlic, ginger).

Flexible Swaps:

• Don’t have flank steak? Sirloin, skirt steak, or even chicken breast work with the velveting technique.
• No bell peppers? Snow peas, broccoli, or snap peas add similar crunch.
• Can’t find black pepper? White pepper is traditional in Chinese cooking (less visible in light sauces).
• No oyster sauce? Use hoisin sauce or double the soy sauce with a teaspoon of sugar.
• Want it spicier? Add red pepper flakes or fresh sliced jalapeños.

Ingredients List

For the Velveted Beef:

Quantity	Ingredient
1 pound	Flank steak, sliced thin against the grain
2 tablespoons	Soy sauce
1 tablespoon	Chinese rice wine (or dry sherry)
1 tablespoon	Cornstarch
1 teaspoon	Sesame oil

For the Pepper Steak:

Quantity	Ingredient
2	Large bell peppers (red and green), sliced
1 medium	Onion, sliced
3 cloves	Garlic, minced
1 tablespoon	Fresh ginger, minced
3 tablespoons	Neutral oil (vegetable or peanut)

For the Sauce:

Quantity	Ingredient
3 tablespoons	Soy sauce
2 tablespoons	Oyster sauce
1 tablespoon	Sugar
1 teaspoon	Black pepper (freshly ground)
1 teaspoon	Cornstarch
1/4 cup	Beef broth or water

Ingredients Notes

Pre-Prepped Items:

• Pre-sliced stir-fry beef from the butcher saves slicing time.
• Frozen bell pepper strips eliminate all chopping.
• Jarred minced garlic and ginger are acceptable shortcuts.
• Pre-cooked rice pouches microwave in 90 seconds.

Flavor Bombs:

• Slice against the grain: Look at the beef. You’ll see lines running in one direction (the grain). Slice perpendicular to those lines. This shortens the muscle fibers, making beef more tender.
• Velveting explained: The cornstarch coating creates a protective barrier that seals in moisture and prevents overcooking. It also gives beef that glossy, silky texture you get at restaurants.
• Why freeze the beef first: Partially frozen beef (20 minutes in freezer) is much easier to slice thinly and evenly.
• Black pepper is the star: Unlike most stir-fries where soy sauce dominates, pepper steak should taste peppery. Use at least 1 teaspoon freshly ground black pepper.
• Oyster sauce secret: This thick, savory sauce adds umami depth without being fishy. It’s a staple in Chinese cooking.

According to Serious Eats, velveting is a technique used in nearly every Chinese restaurant to ensure tender meat, and it works on chicken, pork, and even shrimp.

Step-by-Step Instructions

Prep (15 minutes)

Slice beef thinly against the grain. Mix velveting ingredients. Slice vegetables. Mix sauce ingredients in a bowl. Have everything ready—stir-frying happens fast.

The Method

Velvet the Beef:

1. Slice the steak: Cut flank steak in half lengthwise (with the grain). Then slice each half thinly across the grain into 1/4-inch strips.
2. Marinate: In a bowl, combine sliced beef, 2 tablespoons soy sauce, rice wine, 1 tablespoon cornstarch, and sesame oil. Mix with your hands until beef is evenly coated. Let sit for 10 minutes (or up to 30 minutes in the fridge).

Stir-Fry:

3. Heat the wok: Heat a large wok or skillet over the highest heat. Add 2 tablespoons oil. When smoking hot, add half the beef in a single layer.
4. Sear beef: Let beef sit undisturbed for 1 minute to get a sear. Toss and cook for another 1-2 minutes until just cooked (still a little pink is okay—it’ll cook more later). Remove to a plate. Repeat with remaining beef.
5. Cook vegetables: Add remaining tablespoon of oil. Add onion and bell peppers. Stir-fry for 2-3 minutes until slightly softened but still crisp.
6. Add aromatics: Push vegetables to the side. Add garlic and ginger to the center. Stir-fry for 30 seconds until fragrant.
7. Combine: Return beef to the wok. Mix everything together.
8. Add sauce: Whisk the sauce ingredients again (cornstarch settles), then pour over the beef and vegetables. Toss constantly for 1-2 minutes until sauce thickens and everything is coated.
9. Serve: Remove from heat immediately. Serve over rice.

The Shortcut

The magic moment: When you bite into that first piece of beef and it’s tender, not chewy—that’s when you realize velveting actually works. The cornstarch coating did its job.

Finish

Your pepper steak is done when the beef is tender (not rubbery), vegetables are crisp-tender, sauce is thick and glossy, and everything smells peppery and garlicky.

3 Tips for Faster Cleanup

• One Wok Method: Cook beef, set aside. Cook vegetables in the same wok without washing. Combine with sauce. Only one pan to clean.
• Freezer Bag Marinating: Mix beef and velveting ingredients in a ziplock bag. Massage to coat. No bowl to wash.
• Pre-Mixed Sauce Jar: Double the sauce recipe and keep it in a jar in the fridge for 2 weeks. Shake before using—instant sauce for any stir-fry.

Serving Suggestions

Instant Sides:

• White or jasmine rice: The classic pairing
• Fried rice: Use day-old rice or microwave pouches
• Lo mein noodles: Toss stir-fried noodles with a little soy sauce
• Steamed broccoli: Microwave steamer bags cook in 4 minutes

Complete Meals:

• Pepper steak + white rice + egg drop soup
• Pepper steak over lo mein noodles + spring rolls
• Pepper steak + fried rice + steamed dumplings

Storage & Leftovers

Fridge: Store in an airtight container for up to 4 days. The beef stays tender even after refrigeration—that’s the power of velveting.

Freezer: Freeze for up to 3 months. The sauce may separate slightly when thawed—just stir it back together when reheating.

Reheating:

• Best method: Reheat in a hot skillet with a splash of water or broth. This revives the texture better than microwaving.
• Microwave: 2-3 minutes on high, stirring halfway through. Add a teaspoon of water if it looks dry.

Leftover Ideas:

• Pepper steak fried rice (chop the beef and vegetables, mix into fried rice)
• Pepper steak sandwich (pile on a hoagie roll with provolone)
• Pepper steak wrap (in a tortilla with lettuce)

Frequently Asked Questions

Why is my beef still tough?
You didn’t slice against the grain, or you overcooked it. Flank steak should be cooked quickly over high heat—3-4 minutes maximum. Overcooking makes it chewy.

Can I skip the velveting step?
You can, but the beef won’t be as tender. Velveting is what makes Chinese restaurant beef so different from homemade.

What does “against the grain” mean?
Look at the raw beef. You’ll see parallel lines running in one direction—that’s the grain (muscle fibers). Slice perpendicular (across) those lines, not parallel to them.

Can I velvet the beef ahead of time?
Yes! Velvet the beef up to 24 hours in advance. Store in the fridge until ready to cook.

Is pepper steak spicy?
No, it’s peppery (black pepper flavor) but not spicy-hot. If you want heat, add red pepper flakes or fresh chili peppers.
