Ingredients

For the Beef:

  • 1.5 lbs flank steak, thinly sliced against the grain
  • 1/4 cup cornstarch
  • 1 tablespoon vegetable oil

For the Sauce:

  • 3/4 cup soy sauce (low sodium recommended)
  • 1/2 cup water
  • 1/2 cup brown sugar
  • 1 teaspoon minced garlic
  • 1 teaspoon grated ginger
  • 1/2 teaspoon red pepper flakes (optional)

For Garnish (Optional):

  • 3 green onions, thinly sliced
  • Sesame seeds

Ingredient Highlights

  • Flank Steak: Thin slices cook quickly and absorb the sauce beautifully.
  • Soy Sauce and Brown Sugar: Create the perfect sweet-savory balance for the Mongolian sauce.
  • Garlic and Ginger: Add bold, aromatic flavors.
  • Cornstarch: Helps thicken the sauce for a silky finish.

Step-by-Step Instructions

Prepare the Beef:

  1. Slice and Coat: Thinly slice the flank steak and toss it in cornstarch to coat evenly. This helps create a slightly crisp texture and thicken the sauce.

Cook in the Instant Pot:

  1. Sauté the Beef: Set your Instant Pot to sauté mode and heat the vegetable oil. Add the sliced beef in batches, cooking briefly until browned. Remove and set aside.
  2. Make the Sauce: In the Instant Pot, add the soy sauce, water, brown sugar, garlic, ginger, and red pepper flakes (if using). Stir to combine, scraping up any browned bits from the bottom of the pot.
  3. Pressure Cook: Return the browned beef to the pot, ensuring it’s submerged in the sauce. Close the lid and set the Instant Pot to high pressure for 10 minutes.
  4. Quick Release: Once cooking is complete, use the quick-release valve to release the pressure.

Thicken the Sauce:

  1. Simmer: Set the Instant Pot back to sauté mode. Stir occasionally and let the sauce simmer for 2-3 minutes to thicken. If needed, add a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons water).

Serve:

  1. Garnish and Plate: Serve the Mongolian beef over steamed rice or noodles. Garnish with sliced green onions and sesame seeds, if desired.

How to Serve

  • Over steamed jasmine or basmati rice
  • With lo mein noodles or rice noodles
  • Paired with stir-fried vegetables for a balanced meal

Additional Tips

  • Slice Beef Thinly: For the best texture, slice the flank steak as thin as possible against the grain.
  • Don’t Skip Browning: Sautéing the beef briefly enhances the flavor and texture.
  • Low-Sodium Soy Sauce: Helps control the saltiness of the dish without sacrificing flavor.
  • Customize Spice: Add more red pepper flakes or a dash of sriracha for extra heat.
  • Use a Slurry: If the sauce isn’t thick enough after simmering, a cornstarch slurry will do the trick.

Recipe Variations

  1. Spicy Mongolian Beef
    • For a fiery kick, increase the amount of red pepper flakes, or drizzle in chili oil while the sauce simmers. You can also add sliced fresh chili peppers for an extra layer of heat.
  2. Vegetable Additions
    • Boost the nutrition and add more texture by tossing in vegetables like broccoli, bell peppers, snap peas, or carrots. Simply stir them in during the sauté stage, ensuring they stay crisp-tender.
  3. Healthier Option
    • Make this dish lighter and more health-conscious by substituting soy sauce with coconut aminos and replacing brown sugar with honey or maple syrup. You’ll still enjoy all the flavor with less sodium and added refined sugar.
  4. Chicken Mongolian Style
    • For a leaner protein, swap out the beef for thinly sliced chicken breasts or thighs. Follow the same steps to create a delicious chicken-based variation of Mongolian beef.
  5. Gluten-Free Option
    • Accommodate dietary preferences or restrictions by using gluten-free soy sauce or tamari. Ensure all other ingredients, like cornstarch, are certified gluten-free for a safe and satisfying meal.
  6. Beef and Noodles
    • Take this dish to the next level by serving it over cooked noodles or tossing cooked rice noodles into the pan to absorb the flavorful sauce.
  7. Sweet and Tangy Twist
    • For a different flavor profile, add a splash of rice vinegar or orange juice to the sauce to introduce a tangy element.

Freezing and Storage

  • Storage
    • To keep leftovers fresh, transfer the Mongolian beef to an airtight container and store it in the refrigerator for up to 3 days. For the best flavor and texture, reheat gently on the stovetop or in the microwave until warmed through.
  • Freezing
    • Mongolian beef freezes beautifully, making it a great option for meal prep or saving leftovers. Let the dish cool completely before transferring it to a freezer-safe container or resealable freezer bag. Remove as much air as possible to prevent freezer burn. It can be stored in the freezer for up to 2 months.
  • Reheating Frozen Mongolian Beef
    • To enjoy your frozen leftovers, transfer the beef to the refrigerator the night before to thaw. Reheat in a skillet over medium heat, adding a splash of water or beef broth to help revive the sauce’s smooth, rich consistency. Stir occasionally until heated through, and enjoy!

  • Instant Pot: Essential for cooking the beef quickly while infusing flavors.
  • Tongs: Handy for tossing and removing beef from the Instant Pot.
  • Sharp Knife: For slicing the beef thinly and evenly.
  • Small Whisk: To mix the sauce or cornstarch slurry.
