Step‑by‑Step Instructions for Crispy Mongolian Beef

Step 1: Prepare the Beef
Start by slicing the flank steak against the grain into thin strips, ensuring maximum tenderness. In a mixing bowl, toss the beef slices with cornstarch until each piece is thoroughly coated. Allow the seasoned steak to rest for about 10 minutes; this ensures the cornstarch adheres well and will create that desired crispy texture once cooked.

Step 2: Heat the Oil
In a large skillet, heat about ½ inch of vegetable oil over medium-high heat until it reaches around 350°F (175°C). You can test the heat by dropping in a small piece of cornstarch—if it sizzles immediately, you’re ready to fry. Carefully add the beef slices in a single layer, frying for 2-3 minutes or until they turn golden brown and crispy. Flip them midway for even cooking, and then drain on paper towels to remove excess oil.

Step 3: Sauté the Garlic
Once the beef is crispy and set aside, carefully remove excess oil from the skillet, leaving about 1 tablespoon to sauté. Over medium heat, add minced garlic and cook for about 30 seconds, stirring continuously, until fragrant and just starting to turn golden. This step is crucial as it infuses the oil with delicious garlic flavor, heightening the taste of your Crispy Mongolian Beef.

Step 4: Create the Sauce
To the sautéed garlic, add soy sauce, brown sugar, and water, stirring to dissolve the sugar fully. Allow the mixture to simmer for 2-3 minutes, watching for it to thicken slightly and become glossy. The aroma of the sauce will start to envelop your kitchen, making it hard to resist the anticipation of the delightful Crispy Mongolian Beef.

Step 5: Combine Beef with Sauce
Once the sauce has thickened, gently return the crispy beef to the skillet, tossing it to thoroughly coat each piece in the savory sauce. Simmer for an additional 1-2 minutes, allowing the beef to absorb the flavors. The cornstarch coating will absorb some of the sauce, enhancing the crispy texture while maintaining that signature Mongolian flavor.

Step 6: Add Green Onions
Finally, stir in the chopped green onions, reserving some for garnish later. Cook for about 1 additional minute, allowing the onions to soften slightly while adding a fresh, vibrant touch to your Crispy Mongolian Beef. The mixture should look glossy and vibrant, ready to be served over rice.

Step 7: Serve and Garnish
Spoon the Crispy Mongolian Beef over a bed of warm, fluffy rice, allowing the grains to soak up the flavors of the sauce. Garnish with the reserved green onions for a pop of color and freshness. Serve immediately, and watch your friends and family delight in this delectable homemade dish!

Crispy Mongolian Beef Variations & Substitutions

Feel free to make this Crispy Mongolian Beef your own by exploring these delicious variations!

  • Alternative Protein: Substitute flank steak with thinly sliced sirloin or ribeye for a slightly different flavor yet just as tender.
  • Gluten-Free: Use tamari in place of soy sauce and ensure your cornstarch is certified gluten-free for a completely gluten-free dish.
  • Sugar-Free: Replace brown sugar with coconut sugar or a sugar substitute for a low-sugar version that maintains sweetness.
  • Veggie Boost: Toss in some colorful bell peppers, broccoli, or snap peas for added nutrition and a delightful crunch. The vegetables will absorb the sauce beautifully, enhancing the overall flavor.
  • Spicy Version: Add more crushed red pepper flakes or a splash of Sriracha to kick up the heat for those who like it spicy! Balancing the heat with the sweetness will create a unique flavor experience.
  • Cauliflower Rice Base: Swap out traditional rice for cauliflower rice for a lighter, lower-carb option that still soaks up the delicious sauce.
  • Crispy Tofu: For a vegetarian twist, replace beef with crispy fried tofu. Simply marinate and fry as you would your beef for a delightful plant-based meal.
  • Hoisin Twist: Add an extra tablespoon of hoisin sauce to intensify the sweet, tangy flavor, making every bite even more irresistible!

Don’t forget that sides like steamed veggies or comforting jasmine rice such as in Smashed Broccoli Parmesan can elevate your meal even further. Experiment and enjoy your cooking journey!

Expert Tips for Crispy Mongolian Beef

Coat Well: Make sure every slice of flank steak is coated in cornstarch; this ensures maximum crispiness and a delightful texture.

Avoid Overcrowding: Fry the beef in batches if necessary to prevent steaming; overcrowding the skillet will lead to chewy, soggy pieces instead of deliciously crisp ones.

Correct Temperature: Maintaining the oil at around 350°F (175°C) is crucial for frying. Use a thermometer or test with cornstarch to ensure it’s hot enough for that perfect crust.

Drain Properly: After frying, place the beef on paper towels to absorb excess oil; this will keep your Crispy Mongolian Beef from becoming greasy.

Reheat Carefully: If making ahead, fry the beef briefly again before serving to regain its crispiness, ensuring you enjoy that satisfying crunch in every bite.

Make Ahead Options

Preparing your Crispy Mongolian Beef in advance can save you valuable time during busy weeknights! You can slice the flank steak and coat it in cornstarch up to 24 hours ahead of time, storing it covered in the refrigerator to keep the coating fresh. Additionally, you can make the sauce—combining soy sauce, brown sugar, garlic, and ginger—up to 3 days in advance; simply refrigerate it in an airtight container. When you’re ready to serve, fry the coated beef and then blend it with the prepared sauce for a quick finish. This method ensures your meal retains its delicious flavors and textures, making your dinner just as delightful as if it had been made fresh!

How to Store and Freeze Crispy Mongolian Beef

Fridge: Keep leftover Crispy Mongolian Beef in an airtight container in the fridge for up to 3 days. This helps maintain its flavor while keeping it protected.

Freezer: For longer storage, freeze the beef without the sauce in a freezer-safe bag or container for up to 2 months. Ensure to remove as much air as possible to prevent freezer burn.

Reheating: When ready to enjoy leftover Crispy Mongolian Beef, reheat it in a hot skillet for a few minutes to regain that delightful crunch. You can also add a splash of water or broth to rehydrate if needed.

Make-Ahead Tip: Prepare the sauce and cook the beef separately, storing them in the fridge. Combine just before serving to keep the beef crispy!

What to Serve with Crispy Mongolian Beef

Elevate your dining experience by pairing this savory delight with dishes that complement its rich flavors and textures.

  • Jasmine Rice: Light and fluffy, it perfectly absorbs the glossy sauce, enhancing every bite of beef.
  • Stir-Fried Vegetables: A colorful medley of bell peppers, broccoli, and snap peas adds freshness and crunch, balancing the dish’s sweetness.
  • Sesame Noodles: The nutty flavors in sesame noodles provide a delightful contrast, making them a comforting side option.

For a touch of romance, consider pairing your meal with a lovely Chardonnay. The wine’s crisp acidity cuts through the richness, refreshing your palate with every sip, while harmonizing the sweet notes of the beef. Serve with Green Tea Ice Cream for dessert, offering a cool, creamy finish after that burst of savory goodness!

Crispy Mongolian Beef Recipe FAQs

What type of flank steak should I use for Crispy Mongolian Beef?
Absolutely, selecting the right flank steak is crucial! Look for a piece that is bright red in color with minimal fat marbling, as this will ensure tenderness and flavor. I recommend choosing a flank steak that feels firm to the touch. For extra flavor, opt for a grass-fed variety if available!

How should I store leftover Crispy Mongolian Beef?
After enjoying your Crispy Mongolian Beef, store it in an airtight container in the refrigerator for up to 3 days. Make sure to keep the sauce separate if possible, as this helps maintain the beef’s crispiness. Just reheat in a hot skillet for a few minutes before serving to restore that delightful crunch!

Can I freeze Crispy Mongolian Beef?
Yes! To freeze, allow the cooked beef to cool completely. Place it in a freezer-safe container or a resealable bag, ensuring to remove as much air as possible to prevent freezer burn. You can freeze it without the sauce for optimal texture. It will stay fresh for up to 2 months. When ready to enjoy, simply thaw overnight in the fridge and reheat in a skillet for that crispy finish.

What if my cornstarch coating isn’t crispy?
Very! If you find that your coating isn’t crispy, here’s a solution: Ensure that the corn starch coats the beef evenly and allow it to rest for about 10 minutes before frying. Fry in batches, avoiding overcrowding, as this produces steam and can prevent that beautiful crunch. Also, make sure your oil is hot enough before adding the beef—about 350°F is ideal.

Is there a low-carb option for this recipe?
Of course! For a lower-carb version of Crispy Mongolian Beef, consider serving it on a bed of steamed vegetables or cauliflower rice instead of regular rice. You can also use a sugar substitute in the sauce if you’re watching your carbohydrate intake, making it both delicious and diet-friendly without losing that beloved flavor.

Can I give Crispy Mongolian Beef to my dog?
While the tender beef itself can be a special treat for your furry friend, make sure to keep them away from the seasoning and sauces. Ingredients like soy sauce can be high in sodium and could upset their stomach. Plain cooked meat is always the best option for sharing with pets!
