Ingredients
  

  • 2 pounds of flank steak or beef chuck roast thinly sliced against the grain
  • ¼ cup cornstarch
  • ½ cup low-sodium soy sauce
  • ½ cup brown sugar
  • ¼ cup water
  • 2 cloves garlic minced
  • 1 tablespoon fresh ginger grated
  • ¼ teaspoon red pepper flakes optional
  • 2 green onions sliced (for garnish)

Instructions
 

  • Prepare the beef:
    Slice your beef thinly against the grain. This ensures tender, easy-to-eat pieces. Toss the sliced beef with cornstarch in a large bowl until evenly coated.
  • Mix the sauce:
    In a separate bowl, whisk together soy sauce, brown sugar, water, minced garlic, grated ginger, and red pepper flakes (if using).
  • Layer in the slow cooker:
    Place the coated beef in the bottom of your slow cooker. Pour the sauce mixture over the beef, making sure all pieces are covered.
  • Cook:
    Cover and cook on low for 6-8 hours, or on high for 3-4 hours. The cooking time may vary depending on your slow cooker model, so check for doneness at the lower end of the time range.
  • Finish and serve:
    Once the beef is tender, give it a good stir. If the sauce is too thin, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir it into the slow cooker. Cook on high for an additional 15 minutes or until the sauce thickens.
