How Long Is Lasagna Still Safe To Eat?

Lasagna is a delicious Italian dish that can be served for either lunch or dinner. If you're making it for more than one person, however, chances are you'll have plenty of leftovers to eat another day. But exactly how long can it last before it goes bad? As it turns out, the shelf life of lasagna largely depends on the way it's stored (via Still Tasty). If you're planning to store your leftovers in the refrigerator, it can last anywhere between three to five days before it's no longer safe to eat.

However, lasagna can last at the highest quality for up to three months if it's kept in the freezer. After taking it out of the freezer and thawing it, you can keep it in the refrigerator for an additional three to four days before it starts to spoil and produce a strange odor. Regardless of where you store it, however, you should keep your leftover lasagna in an air-tight container or wrap it tightly in aluminum foil.

How to reheat lasagna

When you're ready to eat the lasagna again, you can heat it up in either the microwave or the oven. To properly reheat lasagna in the microwave, place a serving on a microwaveable dish and pour 2 teaspoons of water over each piece (via Taste of Home). This will help prevent it from getting too dry. Then stick a toothpick down the middle of the piece and drape a paper towel over it. This will prevent the sauce from splattering all over the microwave without the cheese sticking to the towel. After that, you can heat it up in 90-second increments until it's warm enough, which may take a total of up to six minutes.

To reheat it in the oven, however, you'll need to preheat the oven to 350 F and place it in a casserole dish covered with aluminum foil. You can stick a toothpick down the middle if you're only heating up one serving. This will prevent the cheese from touching the foil. Then bake it in the oven for 30 to 45 minutes until the center of the lasagna is 165 F.
