Ingredients
Scale
Beef Marinade
- 1 lb flank steak, thinly sliced against the grain
- 2 tablespoons soy sauce
- 1 tablespoon oyster sauce
- 1 tablespoon cornstarch
Stir-Fry
- 2 tablespoons vegetable oil, divided
- 1 large yellow onion, thinly sliced
- 2 cloves garlic, minced
- 1 teaspoon grated ginger
- 1 tablespoon rice vinegar
- 1 tablespoon water
- 1 teaspoon sesame oil
- 1/4 teaspoon black pepper
Garnish
- Sliced green onions (optional)
- Sesame seeds (optional)
Instructions
- Marinate the Beef: In a medium bowl, toss the thinly sliced flank steak with soy sauce, oyster sauce, and cornstarch until all pieces are evenly coated. Let it marinate for 10 to 15 minutes to enhance flavor and tenderize the meat.
- Sear the Beef: Heat 1 tablespoon of vegetable oil in a large skillet or wok over high heat. Add the marinated beef in a single layer and sear for 1 to 2 minutes on each side until nicely browned. Remove the beef from the skillet and set aside to prevent overcooking.
- Sauté the Onions: Add the remaining 1 tablespoon of oil to the same skillet. Sauté the thinly sliced onions over medium-high heat for 3 to 4 minutes until they soften and begin to caramelize, developing a sweet and rich flavor.
- Add Aromatics: Stir in the minced garlic and grated ginger with the onions and cook for an additional 30 seconds until fragrant, being careful not to burn the garlic.
- Combine and Finish: Return the seared beef to the skillet with the onions and aromatics. Add rice vinegar, water, sesame oil, and black pepper. Toss everything together and cook for another 1 to 2 minutes, allowing the sauce to thicken slightly and coat the beef and onions beautifully.
- Garnish and Serve: Remove from heat and garnish with sliced green onions and sesame seeds, if desired. Serve the stir-fry hot over steamed rice for a complete meal.
Notes
- For added heat, incorporate sliced chili peppers or a dash of chili oil during cooking.
- You can substitute flank steak with sirloin or ribeye depending on availability.
- To make this dish gluten-free, replace soy sauce with tamari.
