Description
A quick and flavorful weeknight dinner featuring tender flank steak and sweet caramelized onions in a savory soy-oyster sauce glaze, ready in just 15 minutes.
Ingredients
Scale
- 1 lb flank steak, sliced thinly against the grain
- 1 large yellow onion, sliced into thin strips
- 1 tbsp cornstarch
- 1/2 tsp black pepper
- 2 tbsp vegetable oil (divided)
- 3 tbsp soy sauce
- 1 tbsp oyster sauce
- 1 tsp sugar
- 1 tbsp water
- 2 cloves garlic, minced
- 1 tsp fresh ginger, grated
- 1 tsp sesame oil (optional)
Instructions
- Slice the flank steak thinly against the grain and place in a bowl. Toss with 1 tablespoon of cornstarch and a pinch of black pepper. Let sit for 10 minutes.
- Slice the onions into thin strips. Mince the garlic and grate the ginger.
- In a small bowl, whisk together soy sauce, oyster sauce, sugar, sesame oil (if using), and water until the sugar is dissolved.
- Heat a large skillet or wok over medium-high heat for 2 minutes. Add 1 tablespoon of oil and swirl to coat.
- Add the beef in a single layer (cook in batches if necessary). Sear for 1-2 minutes per side until browned. Remove beef from pan and set aside.
- Add the remaining 1 tablespoon of oil to the pan. Add onions and cook for 3-4 minutes until soft and golden.
- Add garlic and ginger to the onions; cook for 30 seconds until fragrant.
- Return the beef to the pan. Pour the sauce mixture over everything and toss vigorously for 1-2 minutes until the sauce thickens and coats the ingredients.
- Serve immediately over steamed rice or noodles.
Notes
Slice beef against the grain for maximum tenderness. Do not overcrowd the pan when searing beef to ensure a good crust rather than steaming. If using gluten-free requirements, swap soy sauce for tamari and ensure oyster sauce is gluten-free.
