Ingredients Overview

Beef (Flank or Sirloin Steak)
Thinly sliced against the grain, beef becomes tender and quick-cooking. Flank steak has great flavor and a perfect bite, while sirloin is a bit more tender and forgiving.

Bell Peppers
Red, green, or yellow bell peppers add sweetness, crunch, and color contrast. Slice into strips to match the beef.

Onion
Sweet or yellow onion brings a mellow depth and caramelizes beautifully with high heat.

Soy Sauce
The backbone of the stir-fry sauce. Use low-sodium soy sauce for better salt control.

Oyster Sauce (Optional)
Adds extra richness and umami. If avoiding shellfish, sub with hoisin sauce or more soy.

Cornstarch
Used in the beef marinade to lock in moisture and also in the sauce to thicken it slightly for a glossy finish.

Garlic & Ginger
Aromatic and essential. Fresh is best, but paste or powder can work in a pinch.

Black Pepper
Freshly ground black pepper is crucial — it gives the dish its name and punchy flavor.

Oil for Stir-Frying
Use a neutral oil like canola, peanut, or avocado oil for high-heat cooking.

Step-by-Step Instructions

1. Slice and Marinate the Beef
   Slice 1 lb flank steak thinly across the grain into ¼-inch strips. In a bowl, combine:

• 1 tbsp soy sauce
• 1 tsp cornstarch
• ½ tsp black pepper
• 1 tsp oil

Toss with beef and let sit 10–15 minutes while prepping vegetables.

2. Prep the Sauce
   In a small bowl, whisk together:

• ¼ cup low-sodium soy sauce
• 1 tbsp oyster sauce (optional)
• 1 tbsp cornstarch
• ¼ cup water or beef broth
• 1 tsp sugar
• ½ tsp black pepper

Set aside.

3. Cook the Beef
   Heat 1 tbsp oil in a large skillet or wok over high heat. Add beef in a single layer (cook in batches if needed). Sear 1–2 minutes per side until browned but not overcooked. Remove and set aside.
4. Stir-Fry the Vegetables
   In the same pan, add a bit more oil if needed. Stir-fry:

• 1 large onion, sliced
• 2 bell peppers, sliced

Cook 3–4 minutes until slightly softened and lightly charred on the edges.

5. Add Garlic & Ginger
   Add 2 cloves garlic (minced) and 1 tsp grated ginger. Cook 30 seconds until fragrant.
6. Add Sauce and Combine
   Pour the sauce into the pan. Stir well and simmer until slightly thickened (1–2 minutes). Add the beef back in and toss everything together until well-coated and heated through.
7. Serve Hot
   Remove from heat and serve immediately over steamed rice or noodles. Top with extra cracked black pepper or sesame seeds if desired.

Gluten-Free Option
Use tamari instead of soy sauce and check that oyster sauce (if using) is gluten-free.

Low-Carb Version
Serve over cauliflower rice or shredded stir-fried cabbage.

Meal Prep Tip
Store the cooked steak and veggies in airtight containers for up to 4 days. Keep the rice separate for best texture when reheating.
