It’s quick, satisfying, and incredibly versatile—just like Sheet Pan Quesadillas or a shortcut weeknight fave like Dorito Casserole.

Ingredients
- 1 lb beef sirloin, thinly sliced
- 1 large onion, sliced
- 2 tablespoons oyster sauce
- 2 tablespoons soy sauce, divided
- 1 tablespoon hoisin sauce
- 1 tablespoon cornstarch
- 2 tablespoons vegetable oil, divided
- 2 garlic cloves, minced
- ½ teaspoon sweetener (sugar, honey, or your favorite)
- ½ cup water or beef broth
- 2 green onions, chopped, for garnish
Optional Add-Ins
- Sliced bell peppers for color and crunch
- Mushrooms or snap peas for veggie variety
- Chili flakes or sriracha for a spicy kick
Instructions
Step 1: Marinate the Beef
In a bowl, toss the thinly sliced beef with 1 tablespoon of soy sauce and 1 tablespoon of cornstarch. Let it sit for at least 15 minutes while you prep the rest.
Step 2: Make the Sauce
In a small bowl, combine oyster sauce, the remaining soy sauce, hoisin sauce, sweetener, and water or broth. Stir and set aside.
Step 3: Cook the Beef
Heat 1 tablespoon of oil in a large skillet or wok over high heat. Add beef and stir-fry until just cooked through (2–3 minutes). Transfer to a plate.
Step 4: Sauté the Onions
Add the remaining oil to the skillet. Toss in the sliced onions and stir-fry for 3–4 minutes until softened. Add garlic and cook 1 more minute.
Step 5: Combine and Sauce It
Return the beef to the pan. Pour in the sauce and stir-fry everything together until the sauce thickens slightly and coats the beef and onions (2–3 minutes).
Step 6: Garnish and Serve
Top with chopped green onions and serve hot over rice.
Tips for Success
- Slice beef thinly across the grain for maximum tenderness.
- Prep all ingredients first—this dish moves fast once you start cooking.
