Step‑by‑Step Instructions for Beef and Onion Stir-Fry Step 1: Prepare the Ingredients Begin by slicing the thinly sliced beef into 1/4-inch strips, ensuring uniform pieces for even cooking. Next, cut the onions into half-moons. Arrange your sliced beef and onions on a cutting board, and set aside. This Beef and Onion Stir-fry is all about quick preparation, so let’s have everything ready! Step 2: Marinate the Beef In a mixing bowl, combine the sliced beef with 2 tablespoons of soy sauce, 1 teaspoon of cornstarch, and a pinch of pepper. Toss everything well until the beef is evenly coated. Let the mixture rest for about 10 minutes to allow the flavors to meld together. This marination step is key to achieving juicy and flavorful beef in your stir-fry. Step 3: Heat the Skillet While the beef is marinating, heat a large skillet or wok over high heat until it’s shimmering and very hot. Add 1 tablespoon of vegetable oil and let it coat the bottom of the skillet. This high heat will give your Beef and Onion Stir-fry the perfect sear, creating a delightful texture and flavor in each bite. Step 4: Cook the Beef Carefully add half of the marinated beef to the hot skillet in a single layer. Stir-fry the beef for about 2 minutes on each side until it turns golden brown and is just cooked through. Remove the beef from the skillet and set it aside. Repeat with the remaining beef to ensure even cooking and avoid crowding the pan. Step 5: Sauté Onions and Garlic Lower the heat to medium and add the sliced onions and 3 minced garlic cloves to the same skillet. Cook them for about 4 minutes, stirring occasionally, until the onions become soft and start to caramelize. This step brings out the sweet flavors of the onions, enhancing the delicious taste of your Beef and Onion Stir-fry. Step 6: Combine Ingredients Return the cooked beef along with any juices back to the skillet. Pour in the remaining mixture of soy sauce and cornstarch, stirring everything together. Allow the dish to simmer for about 1 minute until the sauce thickens slightly. This final amalgamation ensures that every bite is packed with rich flavors. Step 7: Serve and Garnish Finish your Beef and Onion Stir-fry by serving it hot over a bed of steamed rice or noodles. Garnish the dish with sliced green onions and a sprinkle of sesame seeds for a delightful presentation. This quick and satisfying meal is ready to be enjoyed, bringing restaurant-quality flavors right to your home table! Expert Tips for Beef and Onion Stir-Fry Slice Against the Grain: Ensuring the beef is sliced against the grain will maximize tenderness, resulting in a delicious bite every time. Cook Onions Slowly: Avoid burning by cooking onions over medium heat until caramelized. This enhances their sweetness and adds depth to the Beef and Onion Stir-fry. Don’t Overcrowd the Pan: When cooking beef, work in batches. Overcrowding can lead to steaming rather than searing, preventing that perfect golden color. Experiment with Marinades: Don’t hesitate to mix in flavor boosters like fresh ginger or additional soy sauce to customize your Beef and Onion Stir-fry to your taste. Quick Heat Control: If you notice the pan is too hot and ingredients are browning too quickly, lower the heat promptly to maintain a balanced cook. What to Serve with Beef and Onion Stir-fry?

Beef and Onion Stir-fry Recipe FAQs What type of beef is best for this stir-fry? Absolutely! For the best results, opt for tender cuts like sirloin or flank steak.
