So, how should lasagna be reheated? The oven is the greatest place to reheat lasagna. For 20 to 25 minutes, reheat the lasagna in the oven at 375 degrees Fahrenheit.

Steps to Reheat Lasagna in the Oven

If you are wondering how to reheat lasagna in the oven, there are several steps that you must follow. First, you must preheat the oven to 325 degrees F. Next, you should sprinkle some water around the edges of the lasagna. This water is used to prevent the pasta from drying out. You should also use a food thermometer to check for an internal temperature of 160-165 degrees F.

The next step is to transfer the lasagna from the dish to a shallow pan. The pan should be large enough to accommodate the lasagna without spilling over. After that, you should open the oven door carefully, as the door can burst from the extreme heat. Do not leave the lasagna in the oven for more than 20 minutes if you reheat more than one slice. Lastly, do not put foil directly on the lasagna, as the cheese will stick to the foil.

Another way to reheat lasagna in the oven is by using an air fryer. The air fryer will make the process quicker and more convenient, but it requires finesse and patience. Another option is to use an oven-safe container with a lid. When using the microwave, you should avoid heating the entire pan. Moreover, large pieces of lasagna won’t reheat evenly, and you’ll end up with dry and cold lasagna inside. Lastly, you can cover the lasagna with aluminum foil, resulting in a crispier top.

Test to See if it’s Hot

If you’re planning on reheating your lasagne, the first thing you should do is check the temperature. The lasagna is ready if the metal on the probe reaches a warm temperature. If it’s still hot, it might need some more time.

If it’s cold, you can try heating it in the microwave. The microwave can reheat a large lasagna for a couple of minutes. However, the oven works well with single servings and larger portions. This method can be time-consuming, so be patient.

When reheating lasagna in the oven, the dish should be hot. You can check its temperature by cutting a small piece from the top. It should be about 165 degrees Fahrenheit. This is a good level for reheating lasagna.

Test to See if it’s Dried Out

If you plan to reheat leftover lasagna, you need to check it carefully to ensure that it is not dried out. Bacteria grow very quickly between 40 and 140 degrees Fahrenheit, which is the “danger zone.” The lasagna should be refrigerated as soon as possible.

If your lasagne is dried out when reheated, try placing it in the microwave for a few minutes. Place the lasagna slices in a microwave-safe dish and add leftover sauce or broth. Heat the lasagna on medium for about 60 to 90 seconds, then uncover and check for doneness.

Before reheating your lasagna, check the oven temperature between 200 and 250 degrees Fahrenheit. You should also cover it with aluminum foil to prevent excess moisture from escaping from the dish. The lasagna will keep its moisture and taste without drying out.

Best Way to Store Lasagna Before Reheating

Within two hours of letting it cool, you should try to refrigerate your lasagna. Bacteria multiply quickly when food is left at room temperature for more than two hours.

It would be a good idea to divide your lasagna into portions so you can reheat it one at a time. Once you’ve finished, put your leftover lasagna portions in airtight containers and store them in the fridge. They will remain fresher for longer if you store them in a tightly sealed container to keep out extra moisture.

A lasagna will remain edible in the refrigerator for up to 5 days.

Can you Reheat Whole Lasagna?

Preparing lasagna the day before is best, so the flavors can combine and meld in the refrigerator. The entire lasagna can be heated up in the oven. An entire lasagna cannot be reheated in the microwave due to its size, but it can be done in the oven while being covered with foil.

The best results are obtained by taking the pan out of the fridge while the oven is preheating and immediately adding food to the pan afterward.

How Long do Leftovers Last?

As noted, you are not required to wait until the food has cooled to room temperature before storing it in the refrigerator. If you need to keep lasagna for longer, portion it into manageable serving pieces and freeze it.

Reheating only a portion of the leftovers while freezing the remainder is an option if you thaw them out in the refrigerator. Frozen leftovers can last for three to four months. However, the USDA FSIS advises that any leftovers must be cooked to a food-safe temperature — at least 165 F throughout — before being refrozen if you thaw frozen lasagna in cold water or the microwave.

If the lasagna is in an oven-safe container, you can reheat frozen lasagna in the oven right away. However, you should make sure that it has been heated through completely. Be warned that the results won’t likely be as good as if the lasagna had been thawed beforehand.

Tips for Safely Reheating Lasagna

  • If you reheat the lasagna to at least 165°F each time, it can potentially be reheated several times. Your leftovers will be sanitized at this temperature, which efficiently destroys the bulk of bacteria. However, we advise only warming lasagna once because the quality deteriorates with each reheat.
  • Always check to see if the food has been ruined before attempting to reheat leftover lasagne sitting in your refrigerator for a while. If the casserole appears or smells off, throw it away.
  • Cooked lasagna can be kept in the fridge for a few days or in the freezer for up to three months.


Lasagne can be transformed into a delicious meal by reheating it. You won’t be able to tell the difference between freshly cooked and reheated when you heat them properly.
