Ingredients List

Gathering high-quality, fresh ingredients is the first step to an unforgettable pepper steak. Here’s what you’ll need, complete with sensory notes and smart substitutions.

• For the Steak & Marinade:
  • 1 lb flank steak or sirloin, thinly sliced against the grain – The key to tenderness. Flank steak offers a robust, beefy flavor and beautiful marbling that soaks up the marinade. Substitution: Skirt steak or even chicken breast/thighs for a different protein.
  • 2 tablespoons soy sauce – For savory umami depth. Substitution: Tamari or coconut aminos for a gluten-free option.
  • 1 tablespoon Shaoxing wine or dry sherry – Adds a subtle, complex sweetness and helps tenderize. Substitution: A splash of rice vinegar mixed with a pinch of sugar.
  • 1 tablespoon cornstarch – The secret to velvety, tender meat and helping the sauce cling beautifully.
  • 1 teaspoon freshly ground black pepper – For a warm, aromatic base note.
  • 1 teaspoon sesame oil – Provides a nutty, fragrant finish to the marinade.
• For the Stir-Fry:
  • 1 large green bell pepper, sliced into strips – Offers a crisp, slightly bitter counterpoint and vibrant green color. Substitution: Red, yellow, or orange bell peppers for sweeter notes.
  • 1 large onion (yellow or white), sliced – Caramelizes slightly for a sweet, savory foundation.
  • 3-4 cloves garlic, minced – For that essential pungent, aromatic kick.
  • 1-inch piece ginger, minced or grated – Adds bright, spicy warmth.
  • 2 tablespoons vegetable oil (divided) – Use a high-smoke point oil like peanut or avocado for best searing.
• For the Black Pepper Sauce:
  • 1/3 cup beef broth or water – Forms the liquid base of the sauce. Beef broth intensifies the meaty flavor.
  • 2 tablespoons oyster sauce – The backbone of the sauce, providing a rich, savory-sweet complexity. Substitution: Vegetarian oyster sauce or more soy sauce with a pinch of sugar.
  • 1 tablespoon soy sauce – Balances the sweetness.
  • 1 tablespoon cornstarch mixed with 2 tablespoons water (slurry) – For a glossy, perfectly thickened sauce.
  • 1-2 teaspoons coarsely ground black pepper (to taste) – This is the star! Freshly ground gives the best floral, spicy aroma.
  • 1 teaspoon brown sugar (optional) – A pinch can round out the flavors and promote caramelization.

Timing

Efficiency is the hallmark of a great stir-fry. This recipe is designed to be a true 30-minute meal from fridge to table, significantly faster than the average home-cooked dinner, which often takes 45-60 minutes.

The secret lies in the parallel processing: while your steak marinates (which takes just 10-15 minutes), you can prep all your vegetables and mix the sauce. Actual cooking in the wok or skillet is a rapid, high-heat process that locks in flavor and texture in mere minutes.

Step-by-Step Instructions

Follow these detailed steps for a flawless stir-fry every single time. I recommend having all your ingredients measured, chopped, and within arm’s reach of the stove (this is called mise en place) before you turn on the heat.

Step 1: Marinate the Steak

In a medium bowl, combine the thinly sliced steak with the soy sauce, Shaoxing wine, 1 teaspoon black pepper, sesame oil, and 1 tablespoon cornstarch. Use your hands to massage the marinade into every piece of beef—this tactile step ensures even coating and better tenderization. Let it sit for at least 10 minutes while you prep everything else. For even more depth, you can marinate it covered in the fridge for up to 2 hours.

Step 2: Prep the Vegetables

Slice the bell pepper and onion into uniform strips, about 1/4-inch thick. This ensures they cook evenly. Mince the garlic and ginger finely so they disperse their flavor throughout the dish without any large, overpowering bites. In a small bowl or measuring cup, whisk together all the sauce ingredients except the cornstarch slurry. In a separate tiny bowl, mix the 1 tablespoon cornstarch with 2 tablespoons cold water to make your slurry. Having the sauce and slurry ready prevents scrambling during the high-heat cooking.

Step 3: Sear the Steak

Heat a large wok or heavy-bottomed skillet over high heat until it’s very hot—a drop of water should skitter and evaporate instantly. Add 1 tablespoon of vegetable oil and swirl to coat. Working in batches to avoid overcrowding (which steams the meat), add the marinated steak in a single layer. Let it sear undisturbed for 60-90 seconds to develop a beautiful brown crust, then flip and cook for another 60 seconds until just cooked through. Remove the steak to a clean plate, leaving any juices in the wok.

Step 4: Stir-Fry the Vegetables

Add the remaining 1 tablespoon of oil to the hot wok. Immediately add the sliced onions. Stir-fry for about 2 minutes until they begin to soften and turn translucent. Add the bell pepper strips and continue to stir-fry for another 2-3 minutes. You want them to be crisp-tender (al dente), with a bit of bright color and snap. Now, push the vegetables to the sides of the wok, creating a well in the center.

Step 5: Create the Sauce

In the center of the wok, add the minced garlic and ginger. Let them sizzle for just 15-20 seconds until incredibly fragrant—be careful not to burn them. Pour in the pre-mixed sauce liquid (beef broth, oyster sauce, soy sauce). Bring it to a rapid simmer. Give your cornstarch slurry a quick re-stir (the starch settles) and then drizzle it into the bubbling sauce while stirring constantly. Within 30-60 seconds, the sauce will transform from thin and watery to glossy and thick enough to coat the back of a spoon.

Step 6: Combine and Serve

Return the seared steak and any accumulated juices back to the wok, along with the stir-fried vegetables. Add the coarsely ground black pepper. Toss everything together vigorously for 1-2 minutes until the steak is heated through and every component is beautifully glazed in the rich, peppery sauce. Do a final taste test—adjust with a splash more soy sauce for saltiness or a pinch of sugar to balance, if needed. Remove from heat immediately to prevent overcooking.

Nutritional Information

The following estimates are for one serving (approximately 1.5 cups of pepper steak) without rice, based on a 4-serving yield. Values are approximate and can vary based on specific ingredients and brands used.

Note: Sodium can be reduced by using low-sodium soy sauce and broth. The dish is a good source of protein, vitamin C from the bell peppers, and iron from the beef.

Healthier Alternatives

You can easily adapt this recipe to fit various dietary needs without sacrificing the bold flavors that make it so special.

• Lower Sodium: Use liquid aminos or reduced-sodium soy sauce, and opt for low-sodium beef broth. The oyster sauce is the main sodium contributor, so you can reduce the quantity by half and compensate with a touch of hoisin or a pinch of mushroom powder for umami.
• Lower Carb/Sugar: Omit the optional brown sugar entirely—the oyster sauce provides enough sweetness for most palates. Serve over cauliflower rice or zucchini noodles instead of white rice.
• Leaner Protein: Swap the flank steak for ultra-lean cuts like top sirloin or even lean ground turkey (adjust cooking time accordingly).
• More Vegetables: Bulk up the dish with additional fiber and nutrients by adding sliced mushrooms, broccoli florets, or snap peas during the vegetable stir-fry stage. Just add a minute or two to the cooking time.

Serving Suggestions

This pepper steak is a versatile centerpiece. Here are my favorite ways to serve it:

• Classic Bed of Steamed Rice: Jasmine or basmati rice is perfect for soaking up the extra sauce.
• Over Noodles: Toss with cooked lo mein, udon, or even spaghetti for a hearty noodle bowl.
