Frozen lasagna does not require thawing before baking, but the cooking time is increased. To keep the same cooking time, you must plan at least one day before to thaw your lasagna.

Things You'll Need


Thaw During Baking

Preheat the oven to 400 degrees Fahrenheit.

Lift the foil lining the baking pan the lasagna was frozen in and transfer the frozen lasagna to a room temperature baking pan. This prevents damage to your baking pans from rapid swings in temperature from going directly to the freezer to the oven.

Cover the new pan with the frozen lasagna in it with a fresh sheet of aluminum foil.

Bake the lasagna for 90 minutes.

Remove the foil cover and brown the top of the lasagna in a 400 degree Fahrenheit oven for another 30 minutes or until the center of the lasagna is hot and bubbly.

Thaw in the Refrigerator

Transfer the frozen lasagna pan to the refrigerator 24 hours before baking the lasagna.

Preheat the oven to 400 degrees Fahrenheit.

Cover the lasagna with a fresh sheet of aluminum foil.

Bake the lasagna for 40 minutes.

Uncover the lasagna and bake for a final 20 to 25 minutes until the top is lightly browned and bubbly.
