FAQs
Can I use frozen beef for this recipe?
It’s best to use fresh, thawed beef for even cooking. If using frozen, thaw it completely before adding to the crockpot.
Can I make this recipe on the stovetop instead of a crockpot?
Yes, you can. Cook the beef and sauce over medium heat in a skillet, simmering until the beef is tender and the sauce thickens, about 20–30 minutes.

- ¼ cup brown sugar
- 3 garlic cloves, minced
- 1 tbsp ginger, grated
Optional Thickener
- 2 tbsp cornstarch (optional)
