What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients to deliver bold flavor and a satisfying crispy texture without the hassle. Most of these are pantry staples, so you probably have them ready to go.

• Flank steak (1 lb / 450g): Thinly sliced across the grain for tenderness. I prefer a lean cut but with enough marbling for flavor.
• Cornstarch (½ cup / 65g): For coating the beef to get that signature crispiness. Arrowroot powder works as a gluten-free swap.
• Vegetable oil (for frying): High smoke point oil like canola or peanut oil is ideal for frying the beef to crispy perfection.
• Garlic (3 cloves, minced): Fresh and pungent, it’s the backbone of the sauce’s flavor.
• Fresh ginger (1 tbsp, minced): Adds a warm, spicy kick that brightens the dish.
• Low-sodium soy sauce (½ cup / 120ml): Look for a naturally brewed brand like Kikkoman for authentic flavor.
• Brown sugar (⅓ cup / 70g): Balances the saltiness with a rich, caramel note.
• Water (½ cup / 120ml): To help dissolve the sugar and thin out the sauce.
• Green onions (2 stalks, sliced): For garnish and a mild onion flavor.
• Red pepper flakes (optional, ¼ tsp): Adds a subtle heat if you like a little kick.

Feel free to swap the flank steak with skirt steak or sirloin if that’s what’s available. For a gluten-free version, use tamari instead of soy sauce and arrowroot instead of cornstarch. I once tried using coconut sugar in place of brown sugar and it gave a lovely subtle twist—worth trying if you’re curious.

Equipment Needed

• Large skillet or wok: A heavy-bottomed skillet or wok works best to get high heat and even cooking. I’ve used cast iron and stainless steel with great results.
• Mixing bowls: For coating the beef and mixing the sauce.
• Tongs or slotted spoon: Essential for frying and handling the crispy beef without breaking it.
• Measuring cups and spoons: For precise ingredient amounts—it really helps with the sauce balance.
• Cutting board and sharp knife: To slice the beef thinly and prepare aromatics.

If you don’t have a wok, no worries—just use your largest skillet and make sure it’s hot before frying. For budget-friendly frying oil, vegetable or canola oil works perfectly fine. I recommend cleaning your skillet promptly after cooking to keep it in good shape, especially if you’re using cast iron.

Preparation Method

1. Slice the beef thinly (about ¼ inch / 0.6 cm thick): Cut across the grain for tenderness. This step takes about 5 minutes. A sharp knife makes a big difference here.
2. Coat the beef with cornstarch: Place the sliced beef in a bowl, sprinkle cornstarch evenly, and toss to coat each piece lightly but thoroughly. This creates that crispy crust when fried.
3. Heat oil for frying: In a large skillet or wok, heat about 1 inch (2.5 cm) of vegetable oil over medium-high heat until it shimmers (around 350°F / 175°C). This should take 3-4 minutes.
4. Fry the beef in batches: Add beef slices carefully, avoiding overcrowding. Fry for 2-3 minutes per batch, turning occasionally until golden and crispy. Remove with tongs or slotted spoon and drain on paper towels. Double frying is optional but recommended for extra crispiness—let the beef rest for 5 minutes, then fry again for 1-2 minutes.
5. Make the sauce: Remove all but 1 tablespoon of oil from the pan. Add minced garlic and ginger, sauté for 30 seconds until fragrant. Pour in soy sauce, brown sugar, and water. Stir and cook over medium heat for 3-4 minutes until sauce thickens slightly and becomes glossy.
6. Toss beef in the sauce: Return the crispy beef to the pan and stir to coat evenly. Cook for another minute to meld flavors and heat through.
7. Garnish and serve: Remove from heat, sprinkle sliced green onions and red pepper flakes if using. Serve immediately over steamed rice or alongside stir-fried veggies.

Watch the sauce carefully as it thickens; it can go from perfect to too thick quickly. If it thickens too much, add a splash of water to loosen it up. When frying, keep the oil hot but not smoking to avoid burning the cornstarch coating.

Cooking Tips & Techniques

One trick I learned the hard way is to slice the beef thinly and evenly—this helps it cook quickly and stay tender. Thick slices can turn chewy or take forever to crisp. Also, patting the beef dry before coating with cornstarch prevents clumps and sogginess.

Double frying the beef makes a world of difference. The first fry cooks it through, and the second quick fry crisps the edges nicely. It’s worth the extra step if you have the time.

Use fresh garlic and ginger for the sauce—pre-minced stuff just doesn’t bring the same punch. Stir the sauce constantly once the sugar dissolves to avoid burning and to get that perfect glossy finish.

Don’t overcrowd the pan when frying; if you do, the oil temperature drops, and the beef ends up greasy instead of crispy. Fry in batches and keep cooked beef warm in a low oven if needed.

Finally, timing is everything. Prep all ingredients before starting to fry because the sauce comes together quickly, and you want to toss the beef while it’s still hot for the best texture.

Variations & Adaptations

• Spicy Mongolian Beef: Add ½ teaspoon of chili garlic sauce or more red pepper flakes to the sauce for heat.
• Gluten-Free Version: Use tamari instead of soy sauce and arrowroot powder instead of cornstarch.
• Vegetarian Twist: Swap the beef for crispy fried tofu cubes or seitan strips, adjusting frying times accordingly.
• Seasonal Veggies: Toss in blanched broccoli florets or snap peas during the last minute of cooking for extra crunch and color.

Personally, I once tried swapping brown sugar with maple syrup—it gave a lovely depth but made the sauce thinner, so I reduced the water a bit. It’s fun to tweak the sweetener to suit your taste or pantry.

Serving & Storage Suggestions

Serve this easy crispy Mongolian beef hot over steamed jasmine rice or with simple stir-fried vegetables for a balanced meal. Garnish with extra green onions or toasted sesame seeds for a nice finish.

Leftovers keep well in an airtight container in the fridge for up to 3 days. The beef will lose some crispiness but reheats nicely in a hot skillet or oven to bring back some crunch. Avoid microwaving if you want to keep the texture.

This dish also freezes well—just cool completely before freezing in portions. Thaw overnight in the fridge and reheat gently on the stove.

Flavors tend to deepen after sitting for a day, so it’s actually a bit better the next day if you can wait. Just reheat with a splash of water or soy sauce to loosen the sauce if needed.
