Step‑by‑Step Instructions for Savory Pepper Steak Recipe
Step 1: Marinate the Steak
In a mixing bowl, combine sliced flank steak with half the soy sauce, cornstarch, and half the black pepper. Mix thoroughly, ensuring the beef is well-coated, then allow it to marinate for at least 15 minutes. This step enhances the flavor and tenderness of the meat, so look for a silky coating on the steak when you’re done.
Step 2: Stir-Fry the Vegetables
Heat 1 tablespoon of vegetable oil in a large skillet over medium-high heat. Once the oil is hot and shimmering, add sliced onions and a medley of bell peppers to the pan. Stir-fry the vegetables for about 3-4 minutes, or until they are slightly tender and vibrant in color. Once cooked, transfer them to a plate and set aside, keeping them warm.
Step 3: Cook the Steak
In the same skillet, return to medium-high heat and add the marinated flank steak, spreading it out in a single layer. Allow the steak to sear undisturbed for about 1 minute until browned, then stir-fry for an additional 2-3 minutes until it’s cooked through and no longer pink. You’ll know it’s ready when it has a beautiful caramelized color.
Step 4: Add Sauce and Vegetables
Prepare the sauce by mixing the remaining soy sauce, water, minced garlic, and sugar (if using) in a small bowl. Pour this mixture over the cooked steak, stirring to combine. Return the previously stir-fried vegetables to the pan and cook everything together for another 2 minutes, allowing the flavors to meld beautifully. The sauce should bubble and thicken slightly, giving the dish a glossy finish.

Make Ahead Options
Busy home cooks will love how easy it is to prepare this Pepper Steak Recipe in advance! You can marinate the flank steak up to 24 hours ahead of time, ensuring maximum tenderness and flavor. Simply mix the steak with soy sauce, cornstarch, and black pepper, then refrigerate. The bell peppers and onions can be sliced and stored in an airtight container for up to 3 days, ready for a quick stir-fry. When you’re ready to serve, simply stir-fry the marinated steak and vegetables together, add the sauce, and enjoy a delicious, homemade meal with minimal effort. With these make-ahead steps, you’ll save precious time on busy weeknights!
