Step-by-Step Instructions
Here’s how to make Easy Mongolian Beef:
Prepare the Beef:
- Slice the Beef: Thinly slice the flank steak or sirloin against the grain into bite-sized strips.
- Coat the Beef: Toss the sliced beef with 1 tablespoon of cornstarch to lightly coat. This will help the beef stay tender and thicken the sauce as it cooks.
Make the Mongolian Sauce:
- Combine the Sauce Ingredients: In a small bowl, mix together the soy sauce, brown sugar, water, hoisin sauce, sesame oil, and red pepper flakes (if using). Stir until the sugar dissolves completely and the sauce is smooth. Set aside.
Cook the Beef:
- Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat.
- Cook the Beef: Add the beef in a single layer and cook for 2-3 minutes, stirring occasionally, until browned and crispy on the edges. Remove the beef from the pan and set it aside.
Make the Sauce:
- Sauté Garlic and Ginger: In the same pan, add a little more oil if needed and sauté the minced garlic and grated ginger for about 30 seconds until fragrant.
- Add the Sauce: Pour the prepared sauce into the pan and bring it to a simmer. Cook for 2-3 minutes, allowing the sauce to thicken slightly.
Combine Beef and Sauce:
- Return Beef to Pan: Add the cooked beef back into the skillet, tossing to coat it evenly in the sauce.
- Thicken the Sauce: In a small bowl, mix the remaining 1 tablespoon of cornstarch with 1 tablespoon of water to create a slurry. Stir this into the sauce and cook for an additional 1-2 minutes, or until the sauce thickens to your liking.
Serve:
- Garnish and Serve: Remove from heat and garnish with chopped green onions. Serve immediately with steamed rice or noodles for a complete meal.

How to Serve
Easy Mongolian Beef can be served in several delicious ways:
- With Steamed Rice: A classic pairing that soaks up the flavorful sauce.
