🛒 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, divided
- 2 tablespoons vegetable oil
- 2 cloves garlic, minced
- ½ teaspoon sweetener
- ½ cup water or beef broth
- 2 green onions, chopped, for garnish
👩🍳 Instructions
1. Marinate the Beef
Place the thinly sliced beef in a bowl. Add 1 tablespoon soy sauce and 1 tablespoon cornstarch, tossing until the beef is evenly coated.
Let it marinate for at least 15 minutes. This helps season the beef and gives it a tender texture when stir-fried.
2. Prepare the Sauce
In a small bowl, combine the oyster sauce, remaining 1 tablespoon soy sauce, hoisin sauce, and sweetener.
Add the water or beef broth and stir until well combined. Set aside.
3. Stir-Fry the Beef
Heat 1 tablespoon vegetable oil in a large skillet or wok over high heat.
Add the marinated beef in a single layer if possible. Stir-fry for about 2–3 minutes, or until the beef is just cooked through.
Transfer the beef to a plate and set aside.
4. Cook the Onions
Add the remaining tablespoon of vegetable oil to the same skillet.
Add the sliced onion and stir-fry for 3–4 minutes, until it begins to soften while still retaining a little bite.
Add the minced garlic and cook for another 30–60 seconds, just until fragrant.
5. Combine Everything
Return the cooked beef to the skillet.
Pour in the prepared sauce and toss everything together. Cook for another 1–2 minutes, allowing the sauce to coat the beef and onions and become slightly thicker.
6. Garnish and Serve
Remove from the heat and sprinkle with chopped green onions.
Serve immediately over steamed rice or your favorite noodles.
⭐ Tips for the Best Beef Stir-Fry
- Slice the beef thinly: Cutting against the grain helps keep the sirloin tender.
- Use high heat: A hot skillet or wok gives the beef better browning and prevents it from steaming.
- Don’t overcrowd the pan: Cook the beef in batches if necessary.
- Don’t overcook the beef: Sirloin cooks quickly, so remove it as soon as it’s just cooked through.
- Prep everything first: Stir-frying moves quickly, so have the sauce, vegetables, and beef ready before you start cooking.
