Ingredients

Scale

For the Beef:

  • 1 ½ pounds beef chuck, thinly sliced (or flank steak)

For the Sauce:

  • ½ cup soy sauce (low-sodium preferred)
  • ½ cup brown sugar (packed)
  • ¼ cup water
  • 3 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 1 tablespoon cornstarch
  • 1 teaspoon sesame oil
  • 1 tablespoon vegetable oil
  • ½ teaspoon red pepper flakes (optional)

For Garnish:

  • 2 green onions, sliced

For Serving:

  • Cooked rice

Instructions

  1. Prepare the Beef: Slice the beef chuck or flank steak into thin strips to ensure the meat absorbs the sauce flavor and becomes tender during slow cooking.
  2. Make the Sauce: In a small bowl, whisk together the soy sauce, brown sugar, water, minced garlic, grated ginger, cornstarch, and sesame oil until well combined.
  3. Combine the Ingredients in the Slow Cooker: Place the sliced beef into the slow cooker, pour the prepared sauce over the meat, stir to evenly coat, and optionally add red pepper flakes for a bit of heat.
  4. Cook on Low: Cover and cook on the low setting for 4 to 6 hours, or until the beef is tender and the sauce has thickened to a rich consistency.
  5. Garnish and Serve: Stir the Mongolian beef once done, serve it hot over steamed rice, and garnish with sliced green onions to add freshness and color.

Notes

  • Choose the Right Cut of Beef: Beef chuck is ideal for slow cooking due to its tenderness and flavor development; flank steak may cook faster but can be less tender.
  • Add More Veggies: Enhance texture and nutrition by including vegetables like bell peppers, carrots, or broccoli during cooking.
  • Control the Sweetness: Adjust brown sugar quantity to suit your preference or substitute with a healthier sweetener.
  • Thicken the Sauce: For a thicker sauce, mix an additional cornstarch slurry after cooking and simmer on high for a few minutes.
  • Use Low-Sodium Soy Sauce: To make a healthier version, opt for low-sodium soy sauce to reduce salt content.
