Ingredients List

Gather these ingredients for an authentic Mongolian Beef Stir‑Fry experience. Each component plays a crucial role in building those complex flavors that make this dish so addictive:

For the Beef and Marinade:

1 pound flank steak, sliced against the grain into thin strips (substitute: sirloin or skirt steak)
2 tablespoons cornstarch
1 tablespoon vegetable oil
1 teaspoon baking soda (optional, for tenderizing)

For the Sauce:

½ cup low-sodium soy sauce (substitute: tamari for gluten-free option)
⅓ cup brown sugar, packed
3 tablespoons water
2 tablespoons hoisin sauce
1 tablespoon rice vinegar
2 teaspoons sesame oil
¼ teaspoon red pepper flakes (adjust to taste)

For the Stir-Fry:

3 tablespoons vegetable oil, divided
4-6 cloves garlic, minced
1 tablespoon fresh ginger, grated
6 green onions, white parts sliced for cooking, green parts reserved for garnish
1 red bell pepper, thinly sliced (optional)
1 cup snow peas or sugar snap peas (optional)
2 teaspoons toasted sesame seeds, for garnish

Timing

Preparation Time: 20 minutes (includes slicing beef and vegetables, mixing sauce)

Marinating Time: 15-30 minutes (can be shortened to 10 minutes if you’re in a hurry)

Cooking Time: 15 minutes

Total Time: 50-65 minutes, which is approximately 30% faster than traditional beef stir-fry recipes that require longer marinating times. This efficiency makes it perfect for weeknight dinners when time is precious.

Step-by-Step Instructions

Step 1: Prepare the Beef

Place your beef in the freezer for 15-20 minutes before slicing—this makes it easier to cut thin, uniform strips. Once chilled, slice the beef against the grain into ¼-inch strips. In a medium bowl, toss the beef strips with baking soda (if using), 1 tablespoon oil, and cornstarch until evenly coated. Let marinate for 15-30 minutes at room temperature.

Step 2: Prepare the Sauce

In a bowl, whisk together soy sauce, brown sugar, water, hoisin sauce, rice vinegar, sesame oil, and red pepper flakes until the sugar dissolves completely. The sauce should have a balanced sweet-savory profile with a hint of tanginess from the vinegar. Set aside to allow flavors to meld while you prepare other components.

Step 3: Prepare Vegetables

Mince garlic, grate ginger, and slice green onions, separating the white and green parts. If using bell pepper and snow peas, slice them into thin, even pieces for quick cooking. Having all vegetables prepped before heating your wok or pan is crucial for stir-fry success.

Step 4: Sear the Beef

Heat a wok or large skillet over high heat until smoking. Add 2 tablespoons vegetable oil and swirl to coat. Working in batches to avoid overcrowding (which causes steaming instead of searing), add beef strips in a single layer and cook undisturbed for 1 minute until browned on the bottom. Flip and cook for another 30 seconds. Transfer to a clean plate and repeat with remaining beef.

Step 5: Stir-Fry Aromatics and Vegetables

In the same wok, add remaining 1 tablespoon oil. Add garlic, ginger, and white parts of green onions, stir-frying for 30 seconds until fragrant. If using bell pepper and snow peas, add them now and stir-fry for 1-2 minutes until crisp-tender. Keep everything moving to prevent burning the aromatics.

Step 6: Combine and Finish

Return beef to the wok along with any accumulated juices. Pour in the prepared sauce and bring to a simmer. Cook for 2-3 minutes, stirring frequently, until the sauce thickens and coats the beef and vegetables with a glossy sheen. The cornstarch from the beef marinade will help thicken the sauce naturally.

Step 7: Garnish and Serve

Remove from heat and sprinkle with reserved green onion tops and toasted sesame seeds. Serve immediately over steamed rice or noodles to capture all the delicious sauce. For an authentic presentation, mound the Mongolian Beef Stir‑Fry slightly off-center on the plate with rice alongside.

Increase the vegetable-to-meat ratio by adding more bell peppers, snow peas, broccoli, or mushrooms for extra nutrients and fiber.

Serving Suggestions

Elevate your Mongolian beef experience with these complementary pairings:

Classic: Serve over jasmine rice or noodles (lo mein, udon, or rice noodles) to soak up the delicious sauce.
Fresh contrast: Add a side of quick-pickled cucumbers with rice vinegar and a touch of sugar for a refreshing counterpoint.
Complete the meal: Pair with a light miso soup starter and steamed edamame for an authentic Asian dining experience.
Family-style: Present alongside other Asian favorites like vegetable spring rolls, dumplings, or a simple cucumber salad for a feast.
Beverage pairing: Serve with jasmine tea, a light lager beer, or a semi-dry Riesling that complements the sweet-savory profile.

Common Mistakes to Avoid

Sidestep these pitfalls for perfect Mongolian beef every time:

Cutting beef with the grain – Always slice against the grain to ensure tender meat. Cutting with the grain results in chewy, tough beef strips.
Overcrowding the pan – This causes the meat to steam rather than sear. Cook in batches for that desirable caramelization.
Using cold beef straight from the refrigerator – Allow meat to come to room temperature for about 20 minutes for more even cooking.
Cooking vegetables too long – They should retain some crispness. Overcooked vegetables become mushy and lose their vibrant color and nutrients.
Not preparing all ingredients before heating the wok – Stir-frying moves quickly! Have everything measured, cut, and ready beside your cooking station.
Neglecting sauce consistency – If your sauce is too thin, mix 1 teaspoon cornstarch with 1 tablespoon cold water and stir in gradually.

Storing Tips for the Recipe

Make the most of your Mongolian beef with these storage and preparation strategies:

Refrigeration: Store leftovers in an airtight container for up to 3 days. The flavors often deepen overnight, making day-two Mongolian beef particularly delicious.
Freezing: While possible, freezing may affect the texture of the vegetables. If planning to freeze, consider undercooking the vegetables slightly. Freeze for up to 2 months in freezer-safe containers.
Reheating: Warm gently in a skillet over medium heat with a splash of water to revive the sauce. Microwave on 70% power with a damp paper towel covering to prevent drying out.
Meal prep: Slice beef and vegetables up to 2 days ahead and store separately in the refrigerator. Mix sauce up to 3 days ahead and refrigerate in a jar.
Serving leftover strategy: Transform leftovers into lettuce wraps, add to fried rice, or stuff into spring roll wrappers for a different meal experience.
