How to reheat lasagna

How to reheat lasagna? For anyone who doesn’t like cooking or doesn’t have the time to make fresh dishes every day, reheating is usually the best solution.

However, it is essential to know how to reheat dishes correctly. One must make sure that the dish is heated evenly and for enough time.

Often, people get confused about the reheating methods of some dishes, like lasagna, cake, grilled chicken, etc.

Since lasagna can be slightly complicated and time-consuming to make, we automatically assume that it is just as challenging to reheat. This article will help answer the age-old question of how to reheat lasagna.

How to Reheat Lasagna: Factors You Need to Know

Reheating lasagna

Sometimes, it is possible for food to become spoiled if heated incorrectly. When it comes to dishes like lasagna, there are certain factors that we must consider while reheating.

These factors are:

1. Covering the Lasagna

An essential tip for correctly reheating lasagna is to keep the dish covered. By doing this, you make sure that the moisture within the lasagna remains intact.

If you attempt to reheat lasagna without covering it, the dish will likely dry out. You must keep the lid on whether you are using a conventional oven or a microwave.

2. Constantly Monitor the Lasagna

We have all experienced that moment when our reheated dish is hot on the outside and ice cold on the inside. This is especially a common issue when trying to reheat lasagna.

Often, the uneven temperature is a result of either not stirring the dish enough or simply not paying close enough attention to it while reheating.

Thus, this brings us to the second crucial factor when reheating lasagna; always keep an eye on the dish and frequently turn it to ensure that it heats evenly.

3. Store, Reheat and Consume

The third factor one must always keep in mind while reheating lasagna or reheating any other dish is immediate consumption. When you have leftover lasagna on the day it was prepared, you must store it immediately.

When you consume the leftovers, make sure you have correctly reheated the lasagna by continually turning the sheets and heating it for the appropriate amount of time. It is advisable to consume the lasagna immediately after reheating it.

How to Reheat Lasagna in the Microwave

Lasagna is a type of dish that can be reheated just as well in a microwave as it can be in the oven.

However, each method has its own steps that must be followed in order to successfully reheat the lasagna without drying it out or making it inedible.

To reheat lasagna in the microwave:

  • Place the dish in a large microwave-safe bowl/plate and cover it with microwave-safe plastic wrap. Make sure that it is sealed thoroughly so that steam will be trapped inside. Remember; it’s essential to have some type of cover on the lasagna.
  • Place dish in the microwave and press the defrost button if you’re trying to reheat lasagna from a frozen state.
  • If you’re reheating lasagna from the fridge, set your microwave timer to 2 to 3 minutes (this duration is appropriate for normal to average-sized lasagnas). Reheating lasagna from the refrigerator should not take as long as frozen lasagna to warm up.
  • Make sure that the lasagna is heated through and through. This means that the lasagna should have an even internal temperature. To do this, pause the microwave timer and move the lasagna layers a bit before continuing to reheat.

To reheat a lasagna in the microwave, you will need a microwave-safe plastic wrap, mittens, and a meat thermometer.

While the microwave is a faster and more convenient method to use when reheating lasagna, it is also beneficial to learn how to reheat lasagna in the oven.

The oven offers a more even heat distribution and retains the dish’s freshness.

To reheat lasagna in the oven:

  • If you intend to reheat lasagna from a frozen state, preheat your oven to 350 degrees F. If you’re simply reheating lasagna from the fridge, preheat the oven to 400 degrees F.
  • Put the leftover lasagna in a lasagna pan, or another type of oven-safe pan, and cover it with tin foil. Place the pan on the middle rack of the oven.
  • Heat the lasagna until you hear or see the fillings sizzle. You may also check the internal temperature of the dish. An internal temperature of 165 degrees F would mean that the lasagna is completely reheated.
  • Remove the foil and let the lasagna heat for an additional ten minutes to make sure that the top is warmed entirely and is a bit toasted.

Remember: To reheat a lasagna in the oven, you will need an oven-safe pan, aluminum foil, a kitchen thermometer, and oven mittens for safe handling.

How to Reheat Lasagna on the StoveHow to reheat lasagna on stove

Though not typically the most common method for reheating lasagna, the stove top can be an efficient way of reheating this delicious dish.

It is important to note that using a stove top to reheat your lasagna is usually only a recommended method when there is only a small quantity of the dish left to reheat.

If you have more than a small amount of lasagna leftovers that you wish to reheat, it is advised that you use one of the alternate methods mentioned in this article.

To reheat lasagna on the stove:

  • Transfer the thawed lasagna into the skillet and place it on the stove over medium to high heat.
  • Add a little water, pasta sauce, or stock along the edges of the skillet.
  • Cover the dish and bring it to a slow simmer. The lasagna will absorb the sauce (or water) and will soften the sheets during this process.
  • Stir and allow it to cook for 15 to 20 minutes. Again, the duration will depend on the quantity of lasagna you are reheating.
  • If you want the top of your lasagna to be a little toasty, you can remove the lid during the last five minutes of the cooking time.

In order to reheat lasagna on the stove, you need a large skillet, pasta sauce (or water), and a lid for the skillet.


Here, we have discussed the three most common ways of reheating lasagna. However, there are still other means of warming it. Sometimes, people use techniques like broiling, grilling, and griddling.

Additionally, some people even use waffle irons to reheat their lasagna. Now that we’ve answered the question of how to reheat the dish, the next question is how long does it take to heat up cold lasagna?

Reheating a cold lasagna, depending on the method you choose, may take anywhere between five and 20 minutes.
