Originally inspired by Chinese-American cuisine, Mongolian beef has become a favorite for its fast cook time, irresistible sauce, and silky texture. The best part? You only need a handful of pantry staples to create that signature glossy, caramelized coating.

Whether you serve it over rice, noodles, or steamed veggies, this dish is a weeknight winner that feels like a treat—without the takeout bill.


Ingredients Overview

Each ingredient in Mongolian beef plays a role in creating a rich umami base, silky texture, and balanced sweet-savory flavor.

Main Ingredients

  • Flank Steak or Sirloin: Thinly sliced against the grain for tenderness. Flank steak is traditional and becomes melt-in-your-mouth tender when cooked quickly at high heat.
  • Cornstarch: Lightly coats the beef to create a crisp sear and helps thicken the sauce. This step is key to the signature glossy finish.
  • Garlic & Fresh Ginger: The aromatic backbone of the sauce. Grated or finely chopped for best distribution.
  • Soy Sauce: Use low-sodium to control salt levels. Adds deep umami flavor.
  • Brown Sugar: Balances the salt and adds a subtle caramelized sweetness.
  • Water or Broth: Slightly thins the sauce while adding volume.
  • Green Onions: Stirred in at the end for freshness, crunch, and color.
  • Neutral Oil: Such as vegetable, canola, or avocado oil for high-heat searing.

Ingredient Tips

  • Slice beef as thinly as possible—freezing it for 20 minutes makes slicing easier.
  • Use dark brown sugar for deeper flavor, or honey for a natural sweetener.
  • Add a splash of rice vinegar or hoisin sauce for variation, but it’s optional.

Step-by-Step Instructions

This recipe comes together fast—so have all your ingredients prepped and ready to go before you start cooking.

1. Prep the Beef

  • Thinly slice 1 lb of flank steak against the grain into 1/4-inch strips.
  • Toss beef with 1/4 cup cornstarch in a bowl until evenly coated.
  • Let it sit for 10 minutes while you prepare the sauce and heat the pan.

Tip: Don’t skip the cornstarch—this is what gives the beef its signature crispy edges and glossy finish.

2. Make the Sauce

In a small bowl, whisk together:

  • 1/2 cup low-sodium soy sauce
  • 1/2 cup water
  • 1/3 cup packed brown sugar
  • 1 tbsp grated fresh ginger
  • 3–4 garlic cloves, minced

Set aside.

3. Sear the Beef

  • Heat 2–3 tbsp oil in a large skillet or wok over medium-high heat.
  • Add beef in a single layer (work in batches if needed).
  • Sear for 1–2 minutes per side until browned and crispy on the edges.

Transfer to a plate once done.

4. Make the Mongolian Sauce

  • In the same pan, pour in the sauce mixture.
  • Bring to a simmer and cook 2–3 minutes until slightly thickened.

Optional: Add a pinch of red pepper flakes for heat or 1 tsp rice vinegar for acidity.

5. Combine and Finish

  • Return the beef to the pan and toss to coat in the sauce.
  • Simmer 1–2 minutes until heated through and sauce thickens.
  • Stir in 3–4 chopped green onions.
  • Serve hot over white rice, brown rice, cauliflower rice, or noodles.

Tips, Variations & Substitutions

Cooking Tips

  • Don’t overcrowd the pan—sear the beef in batches for crisp results.
  • Use a wok or heavy skillet for better heat retention.
  • Let the sauce reduce slightly before adding the beef for a thicker coating.

Variations

  • Spicy Mongolian Beef: Add 1 tsp chili garlic sauce or sriracha to the sauce.
  • Vegetable Version: Toss in snow peas, broccoli, or bell peppers just before serving.
  • Chicken Version: Substitute with sliced chicken breast or thighs for a leaner option.

Substitutions

  • No Brown Sugar? Use maple syrup, honey, or coconut sugar.
  • No Soy Sauce? Use tamari or coconut aminos for gluten-free alternatives.
  • Low-Carb: Serve with shirataki noodles or steamed broccoli instead of rice.

Serving Ideas & Occasions

This dish is a natural fit for:

  • Quick Weeknight Dinners: 30 minutes from prep to plate.
  • Meal Prep: Make a double batch and portion over rice for the week.
  • Dinner Guests: Serve with jasmine rice and a side of stir-fried greens for a restaurant-style meal.

Pair it with:

  • Steamed jasmine or brown rice
  • Stir-fried bok choy or green beans
  • A cucumber salad with rice vinegar and sesame oil

It’s a dish that’s equally fast, flavorful, and deeply satisfying.


Nutritional & Health Notes

Mongolian beef can be a balanced, protein-rich dish when made at home:

  • Protein: 20–25g per serving, depending on cut and portion.
  • Iron & Zinc: Beef delivers essential minerals for energy and immune support.
  • Lower Sugar Version: Reduce brown sugar by half or swap with a low-glycemic sweetener.
  • Sodium Control: Use low-sodium soy sauce and unsalted broth if needed.

Serve with plenty of veggies and a whole grain base for a rounded meal.
