Can You Reheat Frozen Lasagna

First, you’re wondering if this feat is even possible.

Yes, of course, you can reheat frozen lasagna. It’s nothing like reheating a dish that might turn rubbery or tough. It’s really hard to get frozen lasagna wrong.

The worst thing that can happen, honestly, is that you either undercook it or overcook it, and both results are not terrible.

Undercooking your frozen lasagna may result in cold or runny cheese. The insides of the lasagna might be cold, and that’s not a wonderful experience. It might not be pleasant, but it probably won’t be terrible. After all, people eat cold spaghetti and cold pizza all the time.

Overcooking your lasagna may result in crispy or burned outer edges and cheese, which, again, isn’t the worst thing in the world. And it’s pretty easy to avoid as long as you keep an eye on the dish once it nears the end of the set time.

So, you see, it’s not the end of the world, and reheating lasagna will likely turn out amazing regardless of the process you take to get there.

The truth is you can reheat any food that has been refrigerated or frozen. It’s all a matter of using the right appliance with the specific food you’re working with.

For example, foods that have been baked or grilled are often best reheated back in the oven or back on the grill. Foods that have been breaded or fried are often best reheated in the oven or in an air fryer.

With frozen lasagna, we are most likely going to get the best results from the oven, but we’ll run through each appliance just to be sure.

How to Reheat Frozen Lasagna in the Oven

Reheating frozen lasagna in the oven is easily the most efficient, and most obvious, choice for getting this dish back in front of you.

  1. Place your frozen lasagna, still frozen and tightly covered in aluminum foil, on a baking sheet. The baking sheet will help catch any juices that might bubble over during the baking process.
  2. Make sure you place the lasagna in the cold oven then turn the temperature to 350 degrees Fahrenheit.
  3. Heat the lasagna for one hour, checking on it about halfway through then again in the last 10 minutes.
  4. Serve with a green salad and enjoy!

How to Reheat Frozen Lasagna in the Microwave

Reheating frozen lasagna in the microwave can be tricky. You don’t want it to become rubbery, and you can’t heat the whole thing in aluminum or metal in this appliance.

Instead, you’ll have to allow the frozen lasagna to thaw on the counter enough to cut into the lasagna and make portions.

  1. Place one slice onto a microwave-safe plate, cover the lasagna with a lid, and heat it at 50% power for 1 minute.
  2. If necessary, you can heat it for another 30 seconds.
  3. Serve with your favorite side and enjoy!

How to Reheat Frozen Lasagna in an Air Fryer

The air fryer is a wonderful way to reheat this dish. Simply place your lasagna in a loaf pan that will fit inside your air fryer, so the juices won’t drip into the basket.

  1. Preheat your air fryer to 375 degrees Fahrenheit.
  2. Place the loaf pan in the air fryer and cover the pan with aluminum foil.
  3. Heat the lasagna for 10 minutes and check the internal temperature. If necessary, you can heat the lasagna for another 5 minutes, then again for another 5, until the temperature has been met.
  4. Serve with your favorite sides and enjoy!

Okay, I’m not sending you rushing off to the grill to reheat your lasagna. But if you’ve got the grill fired up, you can certainly add this dish to the mix.

  2. Place the frozen lasagna in its metal dish and cover it tightly with aluminum foil onto the grill, lower the heat, and close the lid.
  3. Cook the lasagna at approximately 400 degrees Fahrenheit for an hour and 40 minutes.
  4. If you’re hoping for crispy lasagna, remove the foil and cook for another 15 minutes.
  5. Serve with your favorite side and enjoy!

How to Reheat Frozen Lasagna in a Toaster Oven

The toaster oven is the lifeline for so many college students and other young people just starting out. It’s basically a countertop oven. It cooks hotter and more quickly.

  1. Preheat the toaster oven to 350 degrees Fahrenheit and place the frozen lasagna in its metal tray wrapped and covered tightly with aluminum foil into the oven.
  2. Heat the lasagna for 30-45 minutes or until it is cooked through and bubbling.
  3. Serve with a nice green salad and enjoy!

How to Reheat Frozen Lasagna in a Pan on the Stove

Reheating frozen lasagna on the stovetop is an interesting way to get this dish on your plate. It’s not going to turn out exactly like freshly baked lasagna, but it can be just as good if not better, in its own way.

  1. Thaw the lasagna out enough to slice through it.
  2. Heat a cast iron skillet over medium heat and drizzle olive oil into the bottom of the pan.
  3. Once the oil is heated, place an individual slice of lasagna into the pan and place the lid on top.
  4. After a few minutes, check the lasagna to see if it is heated through. If necessary, you can flip the lasagna, cover it, and cook for another few minutes.
  5. Serve with a green salad and enjoy!

Winner! – The Best Way to Reheat Frozen Lasagna Is Using the Toaster Oven

Look, the best way to cook a full lasagna is in the toaster oven, if you’ve got one. If not, the oven is your next best appliance. However, if you just want an individual slice or two of lasagna, you can use the stovetop and have your dish in front of you in great condition in no time.

So, you really have a lot of options.
