Don’t just stick it in the microwave!

Whether you use homemade tomato sauce or jarred marinara, grate the mozzarella by hand or sprinkle it from a package, add ground meat or vegetables, it takes effort to make a great lasagna. But as any pasta lover will tell you, the time spent in the kitchen is worth it, especially because you'll likely end up with leftovers. Having delicious lasagna that's ready to reheat and serve will make you feel like a dinnertime hero. As long as you reheat it properly.

Yes, it's not as simple as sticking the dish in the microwave on HIGH until it is steaming hot. As lasagna cools, the noodles start to absorb the moisture from the sauce and cheese, making it chewy and dry. You also lose the nice textural difference between the layers of noodles, cheese, and sauce. Although a microwave can reheat lasagna in minutes, this type of high heat cooking will continue to dry it out, leaving you with dried-up sauce and noodles with tooth shatteringly hard edges. Or something a little like an explosion.

Turn on the Oven

Avoid future lasagna disappointment by reheating it in the oven instead. Preheat the oven to 350˚F and cover the lasagna (in an oven-safe dish) with aluminum foil. Place the dish in the oven for about 30 minutes, or until the lasagna is hot all the way through and the sauce is bubbling at the edges.

Turn to the Toaster

If you are reheating individual slices, a toaster oven will work well. Follow the directions above, but lower the temperature to 325˚F. If you don't have a toaster oven, place the slices of lasagna in a foil-lined baking dish or sheet pan and cover the slices loosely with foil. Follow the directions above, checking the slices after 20 minutes for doneness.
