Make Ahead Tip: The sauce ingredients can be mixed the night before and stored in the refrigerator. In the morning simply add the beef to the slow cooker and start cooking.
- Storage: Store leftover beef teriyaki in an airtight container in the refrigerator for up to 4 days.
- Freezing: Let the beef cool completely, then place it in a freezer-safe container or bag with the sauce. Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Warm gently in a saucepan or microwave until heated through. Add a splash of water or broth if the sauce has thickened too much.
