You have two choices. First, thaw it overnight in the fridge. This is the patient, responsible adult way. Your lasagna will reheat evenly and stay moist.
Second option: bake it from frozen. This is the lazy genius way. Preheat your oven to 375°F. Remove the plastic wrap (don’t forget this step, or you’ll have a melty mess) but keep the foil on.
Bake covered for 45 minutes. Then remove foil and bake another 10-15 minutes until bubbly. The cheese gets all golden and crispy. Chef’s kiss.
Can You Microwave It?
Technically, yes. But it’s not the same. The noodles go rubbery. The cheese gets weird. If you’re in a real hurry, microwave a single slice in 30-second bursts.
But for the love of garlic bread, use the oven if you can. Seriously. It’s worth the extra ten minutes. Your taste buds will thank you.
