If you are a fan of lasagna but dislike the hassle of making it at home, count yourself lucky. However, have you ever thought about how restaurants warm up their lasagna?

Restaurants have a few tricks up their sleeves when reheating this Italian classic.

This blog post will discuss the best methods for reheating lasagna so you can enjoy it without all the fuss.

4 Ways Restaurants Reheat Lasagna

1. In The Oven

The first step is to preheat the oven to 375 degrees Fahrenheit. Then, cover the lasagna with aluminum foil and place it on a baking sheet—Bake for about 25 minutes or until it is hot and bubbly. 

Remove the foil during the last few minutes of cooking to allow the cheese to brown. Let the lasagna rest for a few minutes before serving. 

This will give the sauce time to thicken and prevent you from burning your mouth on piping hot food.


Restaurants tend to have their methods and ways of reheating lasagna, but the most common way is in the oven. This dish is usually served hot or warm, so reheating it back to that temperature is essential. 

The lasagna should be heated properly without drying the pasta or making the cheese rubbery.

2. In The Microwave

In most cases, restaurants will reheat lasagna in the microwave. This is typically the quickest and most convenient option. 

The lasagna should be placed on a plate with a damp paper towel to achieve optimal results. The paper towel will help to keep the lasagna moist, preventing it from drying out during the reheating process. 

The lasagna should then be covered with another damp paper towel or a lid before being microwaved for one to two minutes. Once heated, the lasagna can rest for a minute or two before being served.

Once the eight minutes are up, open the air fryer and remove the lasagna. 

Then, use a fork to flake the cheese on the lasagna lightly. Put the lasagna back in the air fryer and cook for another two minutes or until the cheese is melted and bubbly.

 And that’s it. Your lasagna will be hot, cheesy, and delicious – just like it was when you first made it.
