A reheating & storage guide for cooked lasagna, pasta trays, panzerotti, cutlets, and pizza. Choose your dish for an oven starting point.
Lasagna Pans

350°F
175°C equivalent (rounded)
Estimated heating time
45–70 minutes
From chilled
Internal temperature
74°C / 165°F
Check with a food thermometer
Foil & moisture
Seal tightly with foil; uncover for the final 5–10 minutes.
For the best texture
Add a little sauce around the edges before covering. Uncover near the end to melt and lightly brown the cheese.
A shallow cooked lasagna tray; divide deep or densely packed pans for more even heating. Remove delivery packaging and use oven-safe cookware. Times vary: check the centre and several spots in trays; continue heating until the target is reached throughout.
Oven temperatures and time ranges are practical estimates, not restaurant-validated commercial specifications. Follow supplied package instructions when available. For a full catering pan, confirm the restaurant’s instructions by calling 416-781-8383.
Store safely before you reheat
Chill promptly in shallow containers, refrigerate at 4°C / 40°F or colder, and eat within 2–3 days or freeze. Discard cooked food left out for more than 2 hours. Reheat only the portion you plan to eat and discard uneaten reheated leftovers.
What internal temperature should reheated pizza and catering leftovers reach?
Use a food thermometer to check that leftovers reach 74°C (165°F) throughout. Oven times are estimates and depend on portion depth, quantity, oven performance, and starting temperature. Measure the centre and several spots in large trays.
How should I store leftover pasta, pizza, and cutlets?
Refrigerate promptly in shallow containers, with the lid loose until chilled, then cover. Keep refrigerated at 4°C (40°F) or colder and use within 2–3 days, or freeze. Discard cooked food left at room temperature for more than two hours; reheating does not make mishandled leftovers safe.
