Instructions

Marinate the Steak:

1. In a bowl, combine soy sauce, cornstarch, and black pepper.

Stir-Fry the Vegetables:

1. Heat 1 tablespoon oil in a large skillet or wok over medium-high heat.
2. Add sliced onions and bell peppers. Stir-fry for 3–4 minutes until tender-crisp. Remove and set aside.

Cook the Steak:

1. Heat remaining oil in the same pan.
2. Add marinated steak in batches, stir-frying for 2–3 minutes until browned and just cooked through. Set aside.

Prepare the Sauce:

1. In the same pan, sauté minced garlic and ginger for 30 seconds until fragrant.
2. Add beef broth, soy sauce, oyster sauce, hoisin sauce, rice vinegar, sugar, and pepper flakes if using.
3. Bring to a simmer, then add the cornstarch slurry to thicken the sauce.

Combine and Serve:

1. Return steak and vegetables to the pan. Toss to coat evenly in sauce.
2. Cook 2–3 minutes more, until everything is hot and sauce has thickened.
3. Serve hot over steamed white rice. Garnish with sesame seeds and sliced green onions, if desired.

Recipe Notes

• Slice the steak thinly against the grain for maximum tenderness.
• Use red, yellow, or orange bell peppers for added sweetness and color contrast.
• Feel free to double the sauce if you like it extra saucy!
