Step‑by‑Step Instructions for Mongolian Beef
Step 1: Marinate the Beef
In a mixing bowl, combine the sliced flank steak with cornstarch, ensuring each piece is well-coated. Set it aside to marinate for about 15 minutes at room temperature, allowing the cornstarch to adhere to the beef and create a wonderful texture once cooked. This step sets the foundation for your flavorful Mongolian Beef.
Step 2: Sear the Beef
Heat a large skillet or wok over medium-high heat and pour in the vegetable oil. Once the oil is shimmering, carefully add the marinated beef in batches; be cautious not to overcrowd the pan. Sear each batch for about 3-4 minutes, stirring occasionally until the beef develops a rich brown color. Remove the cooked beef from the skillet and set it aside.
Step 3: Sauté the Garlic
In the same skillet, lower the heat slightly, and add the minced garlic, stirring it for about 30 seconds or until fragrant. This quick sauté enhances the flavor profile of your Mongolian Beef, giving it depth. Be careful not to burn the garlic, as burnt bits can turn bitter.
Step 4: Create the Sauce
In a separate bowl, whisk together the soy sauce, brown sugar, ground ginger, and sesame oil until well combined. Pour this mixture into the skillet with the sautéed garlic, stirring gently. Increase the heat and bring the sauce to a lively simmer, allowing the sugars to dissolve and meld into a glossy glaze that will embrace your Mongolian Beef.
Step 5: Combine Beef and Sauce
Return the seared beef to the skillet, tossing it thoroughly in the rich sauce. Let it simmer for an additional 2-3 minutes, allowing the flavors to marry beautifully while the beef absorbs the sweet and savory essence of the sauce. Watch as the beef glistens under the heat, signifying it’s ready to delight your taste buds.
Step 6: Finish with Green Onions
Stir in the chopped green onions, incorporating them into the saucy mixture. Taste and adjust the seasoning with salt and pepper as needed, adding just the right balance to your Mongolian Beef. The vibrant green onions will add both flavor and a pop of color, making your dish visually appealing.
Step 7: Serve and Enjoy
Serve your hot Mongolian Beef over a bed of fluffy rice or noodles, ensuring each portion is generously drizzled with the luscious sauce and garnished with additional green onions for a touch of freshness. This final step elevates your dish and creates a warm family meal that is sure to impress!
