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.
- 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.
