Step-by-Step Instructions for Making Pepper Steak
Step 1: Prep the Beef
Slice the beef into thin strips, about ¼ inch thick, cutting against the grain for maximum tenderness.
In a bowl, toss the beef with 1 tablespoon soy sauce and 2 tablespoons cornstarch until evenly coated. Let it marinate while you prep other ingredients.
Step 2: Prepare the Sauce
In a small bowl, whisk together soy sauce, oyster sauce, hoisin sauce, rice vinegar, brown sugar, beef broth, and sesame oil.
In a separate cup, mix 1 teaspoon cornstarch with 1 tablespoon water to create a slurry. Set aside.
Step 3: Stir-Fry the Beef
Heat 1 tablespoon oil in a large skillet or wok over medium-high heat.
Add the beef in a single layer and sear for 1–2 minutes per side until browned. Do not overcrowd—cook in batches if needed.
Remove the beef and set aside.
Step 4: Cook the Vegetables
In the same skillet, add a bit more oil if needed.
Sauté the onion, bell peppers, garlic, and ginger for 2–3 minutes until crisp-tender.
Step 5: Combine Everything
Return the beef to the skillet.
Pour in the sauce and bring to a simmer.
Add the cornstarch slurry and stir until the sauce thickens and coats the beef and vegetables.
Step 6: Serve
Serve hot over steamed rice, fried rice, or noodles.
Garnish with sesame seeds or chopped green onions if desired.
