Ingredients for Mongolian Beef

Main Ingredients

• 1 lb flank steak (thinly sliced against the grain)
• 1/4 cup cornstarch
• 2–3 tablespoons vegetable oil
• 3–4 green onions (sliced)

Sauce Ingredients

• 3 cloves garlic (minced)
• 1 teaspoon fresh ginger (minced)
• 1/2 cup low-sodium soy sauce
• 1/2 cup water
• 1/2 cup brown sugar

Ingredient Notes

Flank Steak: This cut is ideal because it becomes very tender when sliced thinly against the grain. You can also use sirloin or skirt steak if needed.

Cornstarch: This is essential for achieving that light crispiness on the beef and helps thicken the sauce.

Soy Sauce: Opt for low-sodium soy sauce to keep the dish balanced and not overly salty.

Brown Sugar: Adds sweetness and helps create the signature sticky glaze. You can reduce the amount slightly if you prefer a less sweet dish.

Healthy Swaps:

• Replace part of the sugar with honey for a more natural sweetness
• Add vegetables like broccoli, snap peas, or bell peppers for extra nutrition
• Use lean beef cuts to reduce fat content

Step-by-Step Instructions

Step 1 – Prepare the Beef

Slice the flank steak thinly against the grain. This step is key for tender meat. Toss the slices in cornstarch until evenly coated, then let them sit for about 10 minutes. This helps the coating stick and improves texture during cooking.

Step 2 – Make the Sauce

In a small pan over medium heat, add a bit of oil and sauté the minced garlic and ginger until fragrant. Stir in the soy sauce, water, and brown sugar. Let the mixture simmer for a few minutes until the sugar dissolves and the sauce begins to slightly thicken.

Step 3 – Cook the Beef

Heat oil in a large skillet or wok over medium-high heat. Add the beef in small batches, making sure not to overcrowd the pan. Cook each batch for 2–3 minutes until the edges are crispy and browned. Remove and set aside.

Step 4 – Combine and Finish

Return all the cooked beef to the pan. Pour the prepared sauce over the beef and stir well to coat. Let everything simmer together for a couple of minutes until the sauce thickens into a glossy glaze.

Step 5 – Garnish and Serve

Add sliced green onions and give everything a final stir. Serve hot over steamed rice or noodles.

Pro Tips for Success

• Slice Thinly: Thin slices cook quickly and stay tender
• Don’t Skip Cornstarch: It’s the secret to both texture and sauce thickness
• Cook in Batches: Overcrowding the pan will steam the beef instead of crisping it
• Use High Heat: This helps achieve that restaurant-style sear
• Prep Ahead: Have all ingredients ready before cooking, as the process moves quickly

Flavor Variations

• Spicy Mongolian Beef: Add red pepper flakes or a drizzle of chili sauce
• Garlic Lover’s Version: Double the garlic for a stronger flavor
• Vegetable Boost: Toss in broccoli, carrots, or snap peas
• Low-Sugar Option: Reduce brown sugar and add a splash of orange juice for brightness
• Chicken Alternative: Swap beef for thinly sliced chicken breast or thighs

Serving Suggestions

Mongolian Beef pairs beautifully with simple sides that soak up the delicious sauce. Serve it over steamed white rice, brown rice, or even cauliflower rice for a lighter option.

You can also pair it with noodles, fried rice, or a side of stir-fried vegetables like bok choy or broccoli. For a complete meal, add a light soup or a fresh cucumber salad.

Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
