How to Make Pepper Steak Stir-Fry – Step by Step

Step 1: Marinate the Beef

  • In a large bowl combine the thinly sliced beef with soy sauce and cornstarch. Mix well so each piece is coated.
  • Refrigerate for at least 10 minutes to tenderize and let the flavors penetrate.

Step 2: Sear the Steak

  • Heat a wok or large skillet over medium-high heat until very hot.
  • Add the vegetable oil and sear the beef in a single layer for about 1–2 minutes per side until browned. Work in batches if needed to avoid overcrowding.
  • Remove the beef to a plate and set aside.

Step 3: Stir-Fry the Vegetables

  • In the same pan, add the sliced bell peppers and onion. Stir-fry for 2–3 minutes until they begin to soften but remain crisp.
  • Add the garlic and grated ginger and cook for about 30 seconds until fragrant.

Step 4: Make the Sauce

  • In a small bowl whisk together beef broth, oyster sauce, hoisin sauce, brown sugar, black pepper and sesame oil until smooth.

Step 5: Combine Everything

  • Return the seared beef to the pan with the vegetables.
  • Pour the sauce over the beef and vegetables and stir to combine.
  • Add the cornstarch slurry and cook 1–2 minutes until the sauce thickens and coats the ingredients.

Step 6: Serve & Enjoy

  • Remove from heat and garnish with sliced green onions and sesame seeds.
  • Serve hot over steamed white rice or your favorite grain.

Pro tip: For extra heat, add red pepper flakes, chili oil or a splash of Sriracha to the sauce.

Helpful Tips for the Best Pepper Steak

  • Use the freshest ingredients you can find—crisp peppers and fresh ginger make a noticeable difference.
  • Thinly slice beef against the grain for maximum tenderness.
  • Don’t overcook the steak—quick, high-heat searing preserves juiciness.
  • Adjust the sauce thickness by increasing or decreasing the cornstarch slurry to your preferred consistency.

Cooking Techniques for Perfect Stir-Fry

  • Work with a very hot wok or heavy skillet to achieve a good sear like at a restaurant.
  • Cook in batches and avoid overcrowding the pan so ingredients brown instead of steaming.
  • Prepare the sauce and all ingredients ahead of time (mise en place) to speed up the cooking process.

  • Stir-fried noodles like lo mein for a takeout-style meal
