Oven (ideal): Remove from refrigerator 1 hour before heating to allow it to come to room temperature. If using the aluminum alloy container, simply remove the plastic lid and loosely cover with foil. Or transfer to your own oven-safe ceramic casserole dish, being extra careful with the breadcrumbs. Reheat in a 350°F oven until heated through, roughly 40-45 minutes until bubbling and crusty. Remove the foil for the final 10 minutes of cooking to help ensure even heating.

Microwave (will not form a crust): Remove the plastic lid and heat on high for 4-6 minutes, or until heated through.
