How to Make Crispy Mongolian Beef

Step 1: Prepare the Beef

Start by slicing your flank steak into thin, even strips, cutting against the grain for maximum tenderness. Pat the strips dry with paper towels so the cornstarch sticks better in the next step.

Step 2: Coat in Cornstarch

Place the beef strips in a bowl and toss with cornstarch until evenly coated. This layer forms the crispy crust when fried.

Step 3: Make the Sauce

In a separate bowl, whisk together soy sauce, brown sugar, minced garlic, grated ginger, and if you like, a pinch of red pepper flakes to create the perfect balance of sweet and savory sauce.

Step 4: Fry the Beef

Heat vegetable oil in a large skillet or wok over medium-high heat. Work in batches to fry the beef until golden and crispy on the edges, about 2 to 3 minutes per side. Remove and drain on paper towels.

Step 5: Combine and Cook the Sauce

Discard excess oil from the pan, leaving just enough for flavor, then pour in your prepared sauce. Bring it to a simmer, allowing the sugar to dissolve and the sauce to thicken slightly.

Step 6: Toss Beef in Sauce

Add the fried beef back into the pan, tossing gently to coat every piece thoroughly with the savory sauce. Let it cook for an additional minute to marry the flavors perfectly.

Step 7: Garnish and Serve

Sprinkle freshly sliced green onions over the beef just before serving to add a pop of color and freshness.

Pro Tips for Making Crispy Mongolian Beef

• Dry Your Beef Well: Moisture prevents the cornstarch from crisping up, so patting the beef dry is crucial.
• Do Not Crowd the Pan: Fry the beef in small batches to keep oil temperature high and avoid sogginess.
• Use Fresh Aromatics: Fresh garlic and ginger significantly impact the dish’s flavor depth.
• Adjust Sweetness Gradually: Start with less brown sugar and tweak to taste to avoid overpowering the savory sauce.
• Serve Immediately: Crispy Mongolian Beef tastes best fresh to keep the beef crunchy and the sauce vibrant.

How to Serve Crispy Mongolian Beef

Garnishes

Freshly sliced green onions provide a bright contrast to the savory beef, while optional toasted sesame seeds add a nutty crunch. A sprinkle of finely chopped cilantro or red pepper flakes can also jazz up the presentation and flavor.

Side Dishes

Classic steamed white rice or jasmine rice complements the strong flavors beautifully and absorbs the delicious sauce perfectly. For a lighter option, serve alongside sautéed bok choy or a crunchy cucumber salad to balance the richness.

Creative Ways to Present

Try serving the Crispy Mongolian Beef on a bed of fried rice or inside lettuce cups for a fun, handheld meal. You can also drizzle extra sauce over roasted veggies for a complete plate that dazzles in both taste and presentation.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer leftover Crispy Mongolian Beef to an airtight container and refrigerate. It stays fresh for up to 3 days, maintaining most of its flavor and texture.

Freezing

For longer storage, freeze the cooked beef in a sealed container or heavy-duty freezer bag with the sauce separated if possible. This helps retain crispiness when reheated. Freeze for up to 2 months.

Reheating

To reheat, warm the beef gently in a skillet over medium heat to help revive the crispiness. Avoid microwaving if possible, since it can make the coating soggy.

FAQs

Can I use different cuts of beef for Crispy Mongolian Beef?

Yes, while flank steak is ideal for tenderness and quick cooking, you can also use sirloin or skirt steak as alternatives. Just slice thinly against the grain for the best texture.

How do I make the beef extra crispy?

Ensure your beef is dry before coating with cornstarch, fry it in small batches in hot oil, and do not overcrowd the pan. These steps help lock in that satisfying crunch.

Is this recipe gluten-free?

Not by default, because traditional soy sauce contains gluten. To make it gluten-free, substitute with tamari or another gluten-free soy sauce alternative.

Can I prepare Crispy Mongolian Beef ahead of time?

You can prep the beef by slicing and coating it in cornstarch a few hours before cooking, but for best results, fry and sauce just before serving to maintain the crisp texture.

What can I use instead of brown sugar?

Honey, maple syrup, or coconut sugar are great natural substitutes that will maintain the sweet balance in the sauce while adding their own unique notes.
