Ingredients You’ll Need
- 1 pound flank steak: Tender and flavorful, it’s best sliced thin against the grain to ensure maximum tenderness.
- 1/4 cup cornstarch: This helps create a nice crust on the beef while thickening the sauce. Consider using tapioca starch as an alternative for a similar crunch.
- 1/3 cup water: Balances the flavors in the sauce while allowing it to simmer smoothly. You can substitute with low-sodium beef broth for added richness.
- 1/4 cup low sodium soy sauce: It brings that characteristic umami flavor to the dish without being overly salty. If gluten-free, opt for tamari.
- 1/2 cup brown sugar (packed): This sweetener adds a rich depth to the sauce. Feel free to use coconut sugar for a healthier option.
- 2 teaspoons cornstarch: Used later to thicken the sauce again after the beef is cooked.
- 1/4 cup vegetable oil: Essential for frying the beef – choose a neutral oil with a high smoke point like canola or grapeseed oil.
- 2 garlic cloves (minced): Fresh garlic infuses delicious flavor into the stir-fry. Freshly minced ginger works great as well for extra zest.
- 1 tablespoon minced ginger: This adds warmth and spice to the dish. You can swap it with ground ginger (use 1/4 teaspoon).
- 4 green onions: These add sweetness and freshness, cut into one-inch pieces with the whites and greens separated for a burst of color.
How to Make Mongolian Beef So Good You’ll Skip Takeout Forever
- Prep the Beef: In a large bowl, toss the flank steak with the 1/4 cup of cornstarch until well coated. This process is vital as it helps create that lovely crispy texture.
- Combine the Sauce: In a small bowl, whisk together the 1/3 cup water, 1/4 cup low sodium soy sauce, 1/2 cup brown sugar, and 2 teaspoons cornstarch. Set this beautiful concoction aside for later.
- Cook the Beef: In a large skillet over medium heat, pour in the 1/4 cup vegetable oil. Once shimmering, add the flank steak in batches, making sure not to crowd the pan, and cook for about 3-5 minutes. Remove the beef and keep it warm on a plate covered with foil. Drain excess oil, leaving just 1 tablespoon in the skillet.
- Sauté Aromatics: Add the minced garlic, ginger, and the white parts of the green onions to the hot skillet. Sauté for about 30 seconds until fragrant—just be careful not to burn the garlic!
- Add the Sauce: Pour the prepared sauce into the skillet, scraping up any delicious browned bits left behind. Let it simmer for about one minute, allowing it to thicken and become aromatic.
- Combine Everything: Return the cooked beef to the skillet, tossing to coat with the sauce thoroughly. Cook for an additional 1-2 minutes to heat everything through.
- Garnish and Serve: Sprinkle the green tops of the green onions on top for that fresh crunch. Serve your Mongolian Beef over a bed of fluffy rice for a complete meal!
Storing & Reheating
Store leftovers in an airtight container at room temperature for up to 2 hours or in the refrigerator for 3-4 days. For longer storage, freeze in a freezer-safe container for up to 3 months. When you’re ready to enjoy again, gentle reheating on the stovetop over low heat is best to maintain the beef’s tenderness and revitalizer the sauce. Just note that refrigerating and freezing may alter the texture slightly, but a splash of water during reheating can refresh it nicely.
Chef’s Helpful Tips
- Avoid overcooking the beef; it should just be browned for maximum tenderness and flavor.
- Let the beef rest after cooking to keep it juicy.
- Using a cast iron skillet will give your beef a beautiful sear and added flavor.
- For an extra kick, consider adding some red pepper flakes to the sauce.
- Don’t skip the cornstarch coating; it’s essential for that signature texture!
- This dish is fantastic for meal prep—make it on Sunday and enjoy it throughout the week.
