In the freezer

Freeze cooled portions in sealed freezer containers for up to 2 months for best quality. Thaw overnight in the refrigerator.

Reheat a single portion in the microwave, loosely covered, stirring or turning halfway through. Heat to 165°F / 74°C throughout; add a spoonful of water if needed.

Frequently asked questions

Can I assemble it the night before?

Yes. Cover and refrigerate, then bake in the morning. The texture will be softer and a cold dish may need extra time to reach 160°F / 71°C.
