Ingredients:
- For the Beef:
- 1 ½ lbs (about 680g) beef (flank steak, sirloin, or top round), thinly sliced against the grain into ⅛ to ¼-inch thick pieces
- 1 tablespoon soy sauce (low sodium preferred)
- 1 tablespoon cornstarch (or arrowroot powder)
- 1 teaspoon sesame oil
- ¼ teaspoon black pepper
- For the Stir-Fry:
- 2 large white or yellow onions (about 1.5 lbs / 700g), peeled and sliced into ½-inch thick rings or half-moons
- 2 tablespoons cooking oil (vegetable, canola, or grapeseed oil)
- For the Sauce:
- ½ cup (120ml) beef broth or water
- 3 tablespoons soy sauce (low sodium preferred)
- 2 tablespoons oyster sauce (optional, for richer umami)
- 1 tablespoon dark soy sauce (optional, for deeper color and slight sweetness)
- 1 tablespoon rice vinegar (not seasoned)
- 1 tablespoon granulated sugar (or brown sugar)
- 1 teaspoon cornstarch (or arrowroot powder)
- ½ teaspoon ground white pepper (or black pepper)
- Aromatics (Optional but Recommended):
- 3 cloves garlic, minced
- 1-inch piece fresh ginger, grated or minced
- Garnish (Optional):
- Chopped green onions or fresh cilantro
- Equipment:
- Large non-stick skillet or wok (as seen in image)
- Large mixing bowl
- Small bowl for sauce
- Whisk
- Tongs or spatula
Instructions:
Part 1: Prepare the Beef
- Slice Beef: Place the beef in the freezer for about 20-30 minutes before slicing. This makes it much easier to slice thinly against the grain. Slice the beef into uniform ⅛ to ¼-inch thick pieces. Cutting against the grain is crucial for tender beef.
- Marinate Beef: In a large mixing bowl, combine the thinly sliced beef with 1 tablespoon soy sauce, 1 tablespoon cornstarch, 1 teaspoon sesame oil, and ¼ teaspoon black pepper. Toss well to coat every piece evenly. Let it marinate at room temperature for at least 15-20 minutes while you prepare the other ingredients, or cover and refrigerate for up to 30 minutes. The cornstarch helps tenderize the beef and create a light coating that thickens the sauce.
Part 2: Prepare the Onions and Sauce
- Slice Onions: Peel the onions and slice them into ½-inch thick rings or half-moons. Try to keep the slices relatively uniform so they cook evenly.
- Prepare Sauce: In a separate small bowl, whisk together all the sauce ingredients: beef broth (or water), 3 tablespoons soy sauce, 2 tablespoons oyster sauce (if using), 1 tablespoon dark soy sauce (if using), 1 tablespoon rice vinegar, 1 tablespoon granulated sugar, 1 teaspoon cornstarch, and ½ teaspoon ground white pepper. Whisk until the cornstarch is fully dissolved and there are no lumps. Set aside.
Part 3: Cook the Stir-Fry
- Heat Skillet: Heat 1 tablespoon of cooking oil in a large non-stick skillet or wok over high heat until shimmering and very hot. This high heat is essential for searing the beef.
- Sear Beef in Batches: Add about half of the marinated beef to the hot skillet in a single layer, ensuring not to overcrowd the pan. Cook undisturbed for 1-2 minutes until beautifully browned and caramelized on one side. Flip the beef and cook for another 1-2 minutes until browned on the second side. Do not overcook; the goal is a quick sear to lock in juices. Remove the seared beef from the skillet and set aside. Repeat with the remaining beef, adding another tablespoon of oil if needed.
- Sauté Onions: Reduce the heat to medium-high. Add the sliced onions to the same skillet. Sauté, stirring occasionally, for 5-7 minutes, or until the onions are softened, translucent, and just beginning to caramelize around the edges. If using minced garlic and ginger, add them during the last minute of cooking the onions and stir until fragrant.
- Combine Beef and Onions: Return all the seared beef to the skillet with the softened onions. Toss to combine.
- Add Sauce: Give the prepared sauce a quick whisk again, as the cornstarch can settle. Pour the sauce over the beef and onions in the skillet.
- Simmer and Thicken: Bring the mixture to a simmer, stirring constantly. The sauce will thicken quickly due to the cornstarch. Continue to simmer for 1-2 minutes, or until the sauce has thickened to your desired consistency and coats all the beef and onions beautifully.
Part 4: Serve
- Serve Immediately: Remove the “Savory Beef and Onion Stir-Fry” from the heat.
- Garnish (Optional): Garnish with chopped green onions or fresh cilantro, if desired.
- Serving Suggestions: This dish is best served immediately over hot steamed white or brown rice, or with noodles. It also pairs well with a side of steamed vegetables like broccoli or snap peas.
Tips for Success:
- Thin Slicing: Thinly sliced beef cooks quickly and becomes very tender. Freezing the beef briefly makes slicing much easier.
- High Heat: Cook the beef over high heat in batches to achieve a good sear without steaming the meat. Overcrowding the pan will lower the temperature and prevent proper browning.
- Don’t Overcook Beef: Beef cooks very quickly in a stir-fry. Overcooking will make it tough. Cook until just browned and then remove it from the pan. It will finish cooking when tossed back in with the sauce.
- Taste and Adjust Sauce: Always taste your sauce before adding it to the stir-fry. You can adjust the balance of sweet, savory, and tangy components to your preference.
- Fresh Aromatics: While garlic powder can be used, fresh minced garlic and ginger provide a much more vibrant flavor.
