What’s The Best Way To Cook Frozen Lasagna?

The best way to cook frozen lasagna is to defrost it in the refrigerator overnight and cook it the next day. You can cook the frozen lasagna using the following appliances.

1. Oven

Preheat the oven at 350-375°F depending on the size and number of layers. Cover the lasagna with aluminum foil and place it in the middle racks.

After 40-50 minutes remove the foil and check the internal temperature with a cooking thermometer. If the temperature is 165 °F (74°C) cook for another 5-10 minutes to get a top with nice golden-brown color.

Put the lasagna out of the oven and let it sit for about 10 minutes before you serve it. That will resolidify the cheese and make the layers more stable preventing them to slide and look messy when you cut the lasagna.

2. Convection microwave

You can also cook lasagna in a convection microwave if you have it at home.

A convection microwave is cooking food faster and more evenly due to the circulation of the hot air. Therefore, if you are cooking lasagna in a convection microwave it will be ready for less than 45 minutes.

Preheat the convection microwave at 325°F or 350°F if you cook bigger or thicker lasagna with more layers. Cover it with aluminum foil and don’t let the foil be in contact with the oven cavity, and bake for 35 minutes.

Remove the foil and bake for another 5 minutes allowing the top to get a golden-brown color. Let the lasagna rest for 10 minutes and serve.

3. Air fryer

If you have an air fryer at home you can use it to cook your lasagna.

It is important to use a pan that fits in your air fryer. Turn on the air fryer and preheat at 360°F. Tightly cover the lasagna with aluminum foil, and place it in the air fryer.

Cook the lasagna for about 20 minutes. Remove the foil and cook for an additional 5-10 minutes.

When the cheese is nicely melted and the top of the lasagna is golden brown take it out of the air fryer. Let it cool for about 10 minutes, and serve.

You will enjoy your evenly cooked and tasty lasagna prepared in the air fryer.
