Step‑by‑Step Instructions for The BEST Mongolian Beef Recipe
Step 1: Marinate the Beef
Start by thinly slicing your flank or sirloin steak against the grain. In a bowl, mix together baking soda, cornstarch, kosher salt, vegetable oil, soy sauce, and mirin. Add the sliced beef to the marinade, ensuring it’s well coated. Cover and let it marinate in the refrigerator for at least 1 hour, or up to overnight for maximum tenderness and flavor.
Step 2: Prepare the Sauce
In a separate bowl, combine oyster sauce, hoisin sauce, soy sauce, and brown sugar. Whisk the ingredients together until smooth and well blended, creating a luscious sauce that complements the tender beef. Set the sauce aside for later, allowing the flavors to meld until you’re ready to stir-fry.
Step 3: Stir-Fry the Beef
Heat a large wok or non-stick pan over medium-high heat and add a generous amount of vegetable oil. Once the oil shimmers, carefully add the marinated beef in batches. Stir-fry for 2-3 minutes, or until the beef is caramelized and cooked through. Use a spatula to avoid overcrowding the pan, ensuring even searing. Once cooked, transfer the beef to a plate and set aside.
Step 4: Infuse Flavor
In the same wok, reduce the heat slightly and add minced garlic, ginger, green onion whites, and dried red chilies. Sauté for about 30 seconds until fragrant, mixing constantly to prevent burning. This step will elevate the dish, adding layers of flavor that are essential for the BEST Mongolian Beef.
Step 5: Combine Sauce and Beef
Pour the prepared sauce mixture into the wok, stirring well to combine it with the sautéed aromatics. Bring the mixture to a simmer over medium heat, allowing it to bubble gently. Once simmering, return the cooked beef to the pan, tossing everything together to ensure each slice is well coated in the sticky, tantalizing sauce.
Step 6: Cook Together
Let the beef and sauce simmer for about 5 minutes, stirring occasionally to meld the flavors and thicken the sauce. Keep an eye on the consistency; you want it glossy and flavorful. Adjust the heat as necessary to maintain a gentle simmer without burning the sauce.
Step 7: Serve and Garnish
Once done, serve the hot Mongolian Beef over fluffy rice or alongside steamed vegetables. For an extra touch of freshness, garnish with the reserved green onion tops. This delightful dish not only looks appealing but will also impress your guests with its vibrant colors and irresistible flavors.
