How to reheat frozen lasagna without drying it out.

Lasagna is a classic comfort food that’s perfect for meal prepping in budget-friendly food storage containers or feeding a crowd. But sometimes, when you go to reheat it, it can turn out dry and overcooked. This can be frustrating, especially when you’re craving that creamy, savory flavor. But fear not! With a little bit of care and attention, you can easily reheat lasagna without drying it out.

Below are the best ways to reheat lasagna and 5 top tips to prevent it from drying out.

Reheating Lasagna in the Oven

The oven is probably the best way to reheat a whole lasagna, and for good reason. It allows you to get that perfectly browned, crispy top layer of cheese, while also heating the noodles and filling evenly. Here’s how to do it:

  1. Preheat the oven or toaster oven to 350°F (180°C).
  2. Take the lasagna out of the freezer and let it thaw slightly, until you can easily remove it from the container.
  3. Transfer the lasagna to an oven-safe dish and cover the lasagna with aluminum foil.
  4. Bake the lasagna for about 30 to 40 minutes, or until it is heated through. You can check the temperature with a meat thermometer to make sure it has reached at least 165°F (74°C).
  5. If the top of the lasagna starts to get too browned or dry, you can cover it with additional foil or a piece of parchment paper.
  6. Once the lasagna is heated through, remove the foil and broil it for a few minutes to get the top nice and browned, if desired.
  7. Let the lasagna rest for a few minutes before serving to allow the heat to distribute evenly.

It is important to make sure the filling is heated evenly throughout. A meat thermometer is the best way to check for doneness.

If you have an air fryer that will fit your pan, you can follow these same instructions but change the cooking temperature to 325°F (163°C) and the cooking time to 24 to 32 minutes.

Reheating Lasagna in the Microwave

The microwave is a quick and convenient way to reheat individual lasagna slices from the refrigerator, especially if you’re short on time. Just keep in mind that it won’t give you the same crispy top layer as the oven. Here’s the process:

  1. Place a slice of refrigerated lasagna on a microwave-safe plate or dish. A mini pie pan is the perfect size for a single slice.
  2. Add a few tablespoons of water to the plate, to help keep the lasagna from drying out.
  3. Cover the plate with a damp paper towel or a microwavable lid.
  4. Heat the lasagna on high power for 1 to 2 minutes, or until it is heated through.

If you’re reheating multiple slices of lasagna, you may need to add an additional minute or two of cooking time.

One thing to keep in mind when reheating lasagna in the microwave is to avoid overcooking it. Lasagna tends to dry out quickly when microwaving, so it’s important to keep an eye on it and stop cooking as soon as it’s heated through.

Combining Both Methods

To reheat frozen lasagna by combining oven and microwave cooking, use the following method:

  • Preheat your oven to 350°F (180°C).
  • Take the lasagna out of the freezer and let it thaw slightly.
  • Remove the lasagna from the food container, place it in an oven-safe dish, and cover it with foil.
  • Bake the lasagna for about 20 minutes, or until it is starting to heat through.
  • Remove the foil and cook on high power for 1 to 2 minutes, or until it is fully heated through.
  • If the top of the lasagna is not as browned as you’d like, you can broil it for a few minutes to get it nice and crispy.
  • Let the lasagna rest for a few minutes before serving to allow the heat to distribute evenly.

This method allows you to get the benefits of baking and microwaving — the oven helps heat the lasagna evenly, while the microwave finishes the job and ensures that it is fully heated through. Just make sure to keep an eye on the lasagna as it cooks to avoid drying it out, and be careful when removing it from the microwave as it will be hot.

Tips

By following these 5 tips, you’ll be able to reheat your lasagna without drying it out. Whether you’re reheating leftovers or cooking a frozen lasagna, these tips will help you achieve the perfect balance of moisture and flavor.

So the next time you’re craving a warm, comforting serving of lasagna, don’t be afraid to break out the leftovers. With a little bit of care and attention, you can easily reheat lasagna without drying it out.

  1. Thaw the lasagna slightly before reheating

One of the biggest mistakes people make when reheating lasagna is trying to cook it while it’s still frozen. This can lead to uneven heating and a dry, overcooked final product.

Instead, take the lasagna out of the freezer and let it thaw slightly on the counter or in the fridge before reheating. This will make it easier to remove it from the container and will ensure that it heats up evenly.

  1. Use an oven-safe dish and cover it with foil

To reheat your lasagna, preheat your oven to 350°F (180°C) and place the lasagna in an oven-safe dish. Cover the dish with foil to keep the lasagna moist while it cooks. The foil will also help to prevent the top from getting too browned or dried out.

  1. Check the temperature with a meat thermometer

One of the best ways to ensure that your lasagna is fully cooked and safe to eat is to use a meat thermometer. Insert the thermometer into the center of the lasagna and make sure it reads at least 165°F (74°C). This will ensure that the lasagna is heated through and any bacteria that may be present is killed.

  1. Cover the top with additional foil or parchment paper if necessary

If the top of your lasagna starts to get too browned or dry, you can cover it with additional foil or a piece of parchment paper. This will help to keep the moisture in and prevent the top from getting too crispy.

  1. Let the lasagna rest before serving

After your lasagna is heated through, let it rest for a few minutes before serving. This will allow the heat to distribute evenly and ensure that every bite is just as moist and delicious as the last.

This is great! I'd been wanting to include lasagna in my meal prep but wasn't sure how to go about reheating it. I tried the oven method and it came out just as good as if it were freshly made.
