Equipment

  • Slow cooker

Ingredients

  • 1 cup (240 ml) beef stock
  • cup (80 ml) low sodium soy sauce
  • 2 teaspoons (10 ml) apple cider vinegar or rice vinegar, or white vinegar
  • ½ teaspoon ground white pepper or ground black pepper
  • 2 tablespoons granulated sugar
  • 1 tablespoon (15 ml) toasted sesame oil
  • 3 cloves garlic minced
  • 1 pound pound (450 g) flank steak thinly sliced, or other cuts like chuck roast or skirt steak
  • ¼ cup cornstarch cornflour in the UK
  • 5 cups broccoli florets fresh or frozen

Instructions

  • In a slow cooker, combine the beef stock, soy sauce, apple cider vinegar, white pepper, sugar, sesame oil, and garlic. Whisk until well mixed.
  • Add the steak, stir to coat, then cover and cook on HIGH for 2 hours or on LOW for 5 hours.
  • In a small bowl or jug, mix the cornstarch with ½ cup of the sauce from the slow cooker until smooth.
  • Pour the cornstarch mixture back into the slow cooker, stir in the broccoli florets, and cover. Cook for an additional 15 minutes, then stir once more before serving.

Notes

  • Slow cooker timing: This recipe can be ready in just over 5 hours if you cook on LOW or just over 2 hours if you cook on HIGH. Avoid cooking the beef for longer than this, or you will end up with shredded beef!
  • Slicing the beef: It's very important to slice the beef against the grain. This simple step will ensure that each piece is tender and easy to chew.
  • Any vinegar works. I like to use apple cider vinegar, but you can also use regular white vinegar or rice vinegar.
  • For even more flavor, stir in 1 or 2 teaspoons of freshly grated ginger. You can also add a splash of Oyster sauce or a bit of heat from red pepper flakes or sriracha sauce.
  • To use frozen broccoli, add it to the crockpot according to the directions. It may take a bit longer than 15 minutes to fully cook though, so you might consider adding frozen broccoli 10 or 15 minutes sooner than indicated.
  • Thickening the Sauce: A mixture of cornstarch and cooking liquid thickens the sauce at the end and is the same method used in your favorite Chinese restaurant. For a thicker sauce, simply use more cornstarch.
