What Are Spicy Mongolian Beef?
Spicy Mongolian Beef has roots in Chinese-American cuisine, adapted to suit the American palate. Although it hails from Mongolian traditions, this dish is far from traditional. It typically features tender strips of flank steak, coated in cornstarch, then fried to a perfect crunch and smothered in a savory soy-based sauce with a zing of heat!
What makes Spicy Mongolian Beef unique is its delightful contrast—crispy on the outside but meltingly tender on the inside. The sauce bursts with flavors: sweet, salty, and just the right amount of sparkling spiciness, achieved primarily through a touch of red pepper flakes. Each bite offers everything you love about comfort food while keeping your taste buds dancing with excitement.
This recipe shines on special occasions or even simple family dinners, transforming a typical meal into something special. Whether you’re celebrating a birthday or just trying to boost the spirits after a long week, it’s guaranteed to bring a smile to your face.

Ingredients
- 1 lb flank steak, thinly sliced against the grain
- 1/4 cup cornstarch
- 1/4 cup vegetable oil (for frying)
- 1 tbsp garlic, minced
- 1 tbsp ginger, minced
- 1/2 cup soy sauce
- 1/4 cup water
- 1/4 cup brown sugar
- 1 tsp red pepper flakes (adjust for preferred heat level)
- 2 green onions, chopped (for garnish)
- Cooked rice, for serving
Ingredient Notes:
Flank Steak: This cut is perfect for Spicy Mongolian Beef because it’s lean and becomes tender when marinated and cooked properly. If you can’t find flank steak, sirloin or skirt steak can be great substitutes.
Cornstarch: This will create the signature crunch. Make sure to coat the beef evenly. You can also use potato starch if you have that on hand.
Soy Sauce: Use a low-sodium version if you’re watching your salt intake, but avoid the reduced-sodium versions with added sugars as they can alter the taste.
Red Pepper Flakes: Adjust this according to your heat preference. If you want a milder dish, consider starting with half the amount.
Rice: For a delightful meal, I recommend serving surprise bursts of flavor, like jasmine or basmati rice, which will soak up that heavenly sauce.

Step-by-Step Instructions
Prepare the Beef: Begin by slicing the flank steak thinly against the grain. This ensures tenderness! Toss the steak pieces in cornstarch, ensuring they are evenly coated. Don’t forget to shake off any excess cornstarch, then set aside.
Fry to Perfection: Heat vegetable oil in a large skillet or wok over medium-high heat. Once hot, add the beef in batches, frying until golden brown and crispy (about 2 to 3 minutes per side). Make sure not to overcrowd the pan—a key trick for crispy results! Once done, remove and drain on paper towels.
Aromatics: Reduce the oil in the skillet to about 1 tablespoon. Add minced garlic and ginger, sautéing for 30 seconds to 1 minute until fragrant, being careful not to burn them—the aroma will be heavenly!
Sauce Time: Add soy sauce, water, brown sugar, and red pepper flakes to the skillet. Bring this delightful blend to a boil, then reduce the heat and simmer for 2 to 3 minutes. The smell will be intoxicating.
Combine: Return the crispy beef to the skillet and stir to coat with the sauce. Let it simmer for another 2 to 3 minutes until the sauce thickens and clings to the beef. You’ll know it’s ready when it glistens deliciously!
Serve & Enjoy: Garnish with chopped green onions and serve hot over cooked rice, and watch your loved ones heap praises on you while you enjoy the savory spoils of your labor!
Chef’s Tips:
- For a nice kick, toss in some chopped chili peppers with the aromatics.
- Letting your beef come to room temperature before cooking helps it sear better!
- If your beef clumps together when frying, separate it gently with tongs.
Expert Tips & Tricks
Texture Matters: Ensure your steak is sliced with a sharp knife and against the grain to ensure maximum tenderness.
Cornstarch Coating: For an extra crispy exterior, allow the cornstarch-covered steak to sit for about 10-15 minutes before frying.
Make-Ahead: You can slice the beef and prepare the sauce a few hours in advance, storing them separately in the fridge until you’re ready to cook.
Leftovers: If you have any leftovers, they can be stored in an airtight container. They keep well in the fridge for up to 3 days.
Troubleshooting: If your sauce isn’t thickening, consider mixing an additional teaspoon of cornstarch with a bit of water to create a slurry and adding it to the sauce.
Keep it Fresh: For the best flavor, use fresh garlic and ginger rather than pre-minced options whenever possible.
Serving Suggestions
Pair your Spicy Mongolian Beef with steamed jasmine rice for the perfect textural combination. A side of sautéed vegetables like bell peppers or broccoli not only adds color to the plate but also nutrition! And if you’re trying to impress, serve it all up in a beautiful deep bowl with fresh green onion lightly sprinkled on top. This dish also makes an excellent centerpiece for a casual gathering with friends—don’t forget to pour some chilled wine!
Variations & Substitutions
Vegetarian Version: Replace flank steak with seitan or tofu for a delightful plant-based version. The sauce brings it all together beautifully.
Flavor Additions: Try adding a splash of sesame oil or a bit of hoisin sauce for a different flavor profile.
Seasonal Veggies: Consider adding seasonal vegetables like asparagus in the spring or sliced zucchini in the summer for added nutrients and flavors!
Gluten-Free Twist: Use tamari instead of soy sauce to make it gluten-free without sacrificing flavor.
