📖 Recipe

Black pepper beef is a popular Chinese takeout dish featuring tender beef, crisp vegetables, and a savory, peppery sauce that's best served with steamed white rice.

My family and I would order it at Chinese restaurants, where it was sometimes served sizzling on a hot cast-iron plate and flambéed at the table for a smoky flavor.

For that smoky flavor, you can make this in a carbon steel wok, without flambéing it. If you don't own one, a regular pan will do, but you may not achieve the same smoky flavor. I also found that velveting the beef with baking soda and cornstarch is key to getting that ultra-tender texture I remember from restaurants.

Ingredients & Substitutes

Exact ingredient amounts are listed in the recipe card at the bottom of this page.

main ingredients to make black pepper beef

Flank Steak: I tested several cuts and prefer flank steak because it stays tender when thinly sliced and quickly stir-fried. Sirloin tip, tri-tip, or hanger steak also work.
Bell Peppers: I like using red and green bell peppers, but orange or yellow bell peppers also work. For other vegetables, try thinly sliced carrots or celery, adjusting the cooking time as needed.
Onion: A large shallot also works.
Vegetable Oil: Or use any neutral cooking oil with a high smoke point, such as canola, refined avocado, peanut, or sunflower oil.

Beef Marinade

Garlic Cloves: Fresh garlic works best, but jarred minced garlic also works.
Regular Soy Sauce: Light soy sauce also works. For a less salty option, use low-sodium soy sauce.
Dark Soy Sauce: I prefer using Pearl River Bridge Superior as it gives the beef that dark brown color that other dark soy sauces can't offer. Mushroom-flavored dark soy sauce also works.
Shaoxing Wine: Dry sherry also works.
Cornstarch: This helps velvet the beef and keeps it juicy. Potato starch also works.
Black Pepper
White Granulated Sugar
Baking Soda: This raises the pH of the beef to tenderize it and create a softer texture. Do not skip it!
Vegetable Oil

Sauce

Oyster Sauce: Vegetarian stir-fry sauce also works.
Dark Soy Sauce: Mushroom-flavored dark soy sauce also works.
Regular Soy Sauce: Light soy sauce also works. For a less salty option, use low-sodium soy sauce.
Black Pepper
Shaoxing Wine: Dry sherry also works.
Cornstarch: This thickens the sauce so it coats the beef. Potato starch also works.
Chicken Stock or Broth: Use low-sodium or unsalted stock to better control the saltiness. Unsalted beef broth or cold water also work.

Note: Asian ingredients are typically available at most Asian grocery stores or online.

Expert Tips

Partially freeze the beef: Freeze for 45-60 minutes until the exterior is firm for easier thin slicing.
Slice against the grain: This shortens the muscle fibers for more tender beef.
Marinate for 15-20 minutes: Give the baking soda and cornstarch time to tenderize the beef.
Prep everything first: Have all ingredients ready because the stir-frying process moves quickly.
Keep the vegetables crisp: Stir-fry them briefly so they retain some crunch.

Instructions

Below are step-by-step instructions on how to make black pepper beef:

Sliced flank steak cut against the grain into thin strips.

Slice the beef: Using a sharp knife, slice the flank steak against the grain at a 45° angle into ¼-inch-thick strips.

Sliced beef mixed with the marinade in a large bowl.

Marinate the beef: Transfer the beef strips to a large bowl. Add the beef marinade ingredients and mix well. Marinate for 15-20 minutes and set aside.

Black pepper sauce ingredients combined in a small bowl until the sugar dissolves.

Make the sauce: In a small bowl, combine the sauce ingredients until the sugar has fully dissolved and set aside.

Marinated beef searing in a single layer in a hot pan until lightly browned.

Cook the beef: Heat the vegetable oil in a large pan or wok over medium-high heat. Once hot, add the beef in a single layer, cooking in batches if needed to avoid overcrowding. Sear on both sides until cooked through with lightly browned edges, about 2-3 minutes. Remove and set aside.

Onions and bell peppers stir-frying in a pan until crisp-tender.

Stir-fry the vegetables: Stir-fry the onions and bell peppers for about 30 seconds until crisp-tender.

Beef, onions, and bell peppers coated in a thick, glossy black pepper sauce.

Thicken the sauce and finish: Re-whisk the sauce and pour it into the pan. Simmer for about 1 minute until glossy and thick enough to coat the back of a spoon. Return the beef and toss briefly until evenly coated and heated through. Serve immediately.

Storage & Reheating

Refrigerator: Store leftovers in an airtight container for up to 4 days.
Freezer: Freeze in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating: Microwave or reheat in a pan over medium heat until heated through.

Variations

Chicken: Substitute the beef with thinly sliced chicken breast or boneless skinless chicken thighs.
Gluten-Free: Use gluten-free soy sauce or tamari in place of regular soy sauce, gluten-free dark soy sauce, gluten-free oyster sauce, gluten-free chicken stock, and dry sherry instead of Shaoxing wine.

Pairing Suggestions

Serve Chinese black pepper beef with:

Steamed White Rice: Perfect for soaking up the savory sauce.
Garlic Green Beans: Adds a crisp vegetable side.
Egg Drop Soup: A light and comforting starter.

FAQ

Why is my beef tough?

The beef can become tough if it's sliced with the grain, cut too thick, or overcooked. Slice it thinly against the grain, marinate it for 15-20 minutes with the baking soda and cornstarch, and cook it quickly just until done.

Why is my black pepper sauce too thin?

Make sure to re-whisk the sauce before adding it to the pan, as the cornstarch can settle at the bottom. Let the sauce simmer until glossy and thick enough to coat the back of a spoon before returning the beef.
