What’s The Best Way To Reheat Lasagna?

The most efficient way to reheat your lasagna is in the oven. Microwaves work fast, but they hardly ever heat anything evenly.

Reheating it too often causes it to dry out and lose some of its flavors. 

Start by preheating the oven to a temperature of 350 degrees Fahrenheit. Place the lasagna in an oven-safe dish and cover it with aluminum foil. Heat the lasagna for about 30 minutes or until all the layers of the lasagna are uniformly hot. 

You can also add some sauce to your lasagna before reheating it.
