How to Know It's Ready
The casserole should be heated through and the top should be slightly bubbly.
Troubleshooting
- If the top starts to brown too quickly, cover it with foil to prevent burning.
- If the casserole is still cold in the center, continue heating in 5-minute increments.
- Avoid using the convection setting as it might dry out the casserole.
- For a crispier top, remove the foil during the last 5 minutes of reheating.

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat following the instructions above.
Variations
- Add a sprinkle of cheese on top before reheating for extra flavor.
