Ingredients Method Notes

Ingredients
  

  • 1 ½ pounds flank steak, thinly sliced and chopped into 2-inch pieces
  • 1 cup beef broth
  • ⅔ cup low sodium soy sauce
  • ⅓ cup brown sugar
  • 1 tablespoon sesame oil
  • 1 tablespoon minced garlic
  • ¼ teaspoon red chili flakes (optional)
  • 4 cups broccoli florets
  • 2 tablespoons cornstarch
  • 4 tablespoons cold water

Method
 

  1. Lightly grease the inside of your slow cooker to prevent sticking. Add the flank steak, beef broth, soy sauce, brown sugar, sesame oil, garlic, and optional red chili flakes. Stir everything together to combine.
  2. Cover and cook on high for 2-3 hours or low for 4-5 hours, until the steak becomes tender and soaks up all those delicious flavors.
  3. About 20 minutes before serving, mix the cornstarch and cold water in a small bowl until smooth. Uncover the slow cooker, add the cornstarch mixture, and stir. Cover again and let cook for an additional 20-25 minutes to thicken the sauce.
  4. While the sauce thickens, steam your broccoli. Place the florets in a microwave-safe container with ½ inch of water. Vent the lid, microwave on high for 3 minutes, and drain.
  5. Stir the steamed broccoli into the slow cooker, making sure it’s coated in the sauce. Serve hot over rice or noodles, and enjoy!
