This Crockpot Mongolian Beef recipe delivers tender, flavorful beef simmered in a savory-sweet sauce, perfect for an easy and comforting meal.

Ingredients

Scale

Beef and Marinade

  • 1 1/2 lbs flank steak, sliced thin
  • 1/2 cup soy sauce
  • 1/4 cup brown sugar
  • 3 garlic cloves, minced
  • 1 tsp ginger, minced

Thickener

  • 2 tbsp cornstarch
  • 1/4 cup water (to mix with cornstarch)

Instructions

  1. Prepare the ingredients: Thinly slice the flank steak and mince the garlic and ginger to ensure even cooking and maximum flavor infusion during the slow cooking process.
  2. Combine in crockpot: Place the sliced beef, soy sauce, brown sugar, minced garlic, and ginger into the crockpot. Stir gently to combine all ingredients evenly.
  3. Slow cook the beef: Cook the mixture on low heat for 4 hours to allow the beef to become tender and the flavors to develop fully.
  4. Thicken the sauce: About 30 minutes before the cooking time ends, mix the cornstarch with 1/4 cup of water until smooth, then stir this slurry into the crockpot to thicken the sauce. Continue to cook for the remaining 30 minutes.
  5. Serve: Once the sauce has thickened and beef is tender, serve hot over steamed rice for a delicious, easy meal.

Notes

  • Be sure to slice the flank steak thinly for best texture and tenderness.
  • If you prefer a less sweet sauce, reduce the brown sugar slightly.
  • For a gluten-free version, use tamari instead of soy sauce.
  • Serve with steamed rice or your choice of vegetables for a complete meal.
  • You can add sliced green onions or sesame seeds as garnish to enhance flavor and presentation.
