But what do you do when you have leftover lasagna that you can’t finish? Can you freeze it and enjoy it later? The answer is yes, you can! Freezing lasagna is a great way to save time and money, especially when you have a busy schedule.

In this article, we’ll discuss the benefits of freezing lasagna, factors to consider before freezing, how to freeze lasagna, and tips for freezing lasagna.

Benefits of Freezing Lasagna

Freezing lasagna has several benefits, including convenience, time-saving, and cost-effectiveness. Let’s take a closer look at each of these benefits.


Freezing lasagna is incredibly convenient, especially when you have a busy schedule. You can prepare a large batch of lasagna, freeze it in portions, and enjoy it later when you don’t have time to cook. This is especially useful for working parents, students, or anyone who doesn’t have a lot of time to prepare meals.


Freezing lasagna is also a great way to save time. You can prepare a large batch of lasagna over the weekend and freeze it for later. This way, you don’t have to spend time cooking during the week when you’re busy with work or other activities. All you have to do is defrost and reheat the lasagna, and you’ll have a delicious meal in no time.


Freezing lasagna can also be cost-effective. When you prepare a large batch of lasagna, you can buy ingredients in bulk, which is often cheaper than buying smaller portions. This way, you can save money on groceries and still enjoy a delicious meal. Additionally, freezing leftovers helps to reduce food waste and save money.

Factors to Consider Before Freezing Lasagna

Before you freeze lasagna, there are a few factors you need to consider to ensure that it freezes well and tastes delicious when you reheat it. These factors include the ingredients used, storage container, and preparation technique.

Ingredients Used

The ingredients you use in your lasagna can affect its texture and flavor when you freeze it. For example, if you use ingredients that don’t freeze well, your lasagna may become mushy or watery when you reheat it. Some ingredients that don’t freeze well include sour cream, mayonnaise, and certain types of cheese. It’s best to avoid these ingredients when you’re making lasagna that you plan to freeze.

Storage Container

The storage container you use is also important when you’re freezing lasagna. You want to use a container that’s airtight and freezer-safe. This will prevent freezer burn and keep your lasagna fresh for longer. You can use a plastic container or a freezer-safe glass container with a tight-fitting lid. Alternatively, you can use aluminum foil, plastic wrap, or freezer bags to wrap your lasagna portions.

Preparation Technique

The preparation technique you use can also affect the quality of your frozen lasagna. It’s important to cool your lasagna completely before freezing it. If you freeze it while it’s still hot, it can create condensation and cause freezer burn. Additionally, it’s best to cut your lasagna into portions before freezing it. This makes it easier to defrost and reheat later. You can also add a layer of plastic wrap or aluminum foil between each portion to prevent them from sticking together when they freeze.

How to Freeze Lasagna

Now that you know the factors to consider before freezing lasagna, let’s take a look at how to freeze it.

Cooling the Lasagna

Once your lasagna is cooked, let it cool completely before freezing it. This can take a few hours, so plan accordingly. You can speed up the cooling process by placing the lasagna in the refrigerator for an hour or two before transferring it to the freezer.

Cutting and Wrapping the Lasagna

Once your lasagna is cooled, cut it into portions that you can easily reheat later. You can use a knife or a pizza cutter to cut it into square or rectangular portions. Then, wrap each portion tightly with plastic wrap or aluminum foil. You can also use freezer bags to wrap the portions. Make sure to remove as much air as possible to prevent freezer burn.

Storing the Lasagna in the Freezer

Once your lasagna portions are wrapped, place them in an airtight container or freezer bag. Label the container or bag with the date and contents, and place it in the freezer. Make sure to store the lasagna portions away from other foods to prevent them from getting crushed or damaged.

How to Thaw and Reheat Frozen Lasagna

When you’re ready to enjoy your frozen lasagna, you’ll need to thaw and reheat it. Here are some methods to consider:

Methods of Thawing

There are a few methods to thaw frozen lasagna:

  • Refrigerator: This is the best and safest method for thawing lasagna. Simply transfer the frozen lasagna from the freezer to the refrigerator and let it thaw overnight.
  • Microwave: You can also use a microwave to thaw your lasagna. Place the frozen lasagna in a microwave-safe dish and defrost it on the defrost setting. Check the lasagna every few minutes and rotate the dish to ensure that it thaws evenly.
  • Cold Water: You can also thaw lasagna in cold water. Place the frozen lasagna in a sealed bag and submerge it in cold water. Change the water every 30 minutes until the lasagna is thawed.

Techniques for Reheating

Once your lasagna is thawed, you can reheat it using a few different techniques:

  • Oven: Preheat your oven to 375°F. Remove the plastic wrap or aluminum foil from the lasagna and cover it with foil. Bake the lasagna for 45-60 minutes, or until it’s heated through. Remove the foil and bake for an additional 10-15 minutes to crisp up the top layer.
  • Microwave: Remove the plastic wrap or aluminum foil from the lasagna and cover it with a microwave-safe dish. Microwave the lasagna on high for 5-7 minutes, or until it’s heated through.
  • Stovetop: You can also reheat lasagna on the stovetop. To do this, add a small amount of water or broth to a large saucepan and bring it to a simmer. Place the lasagna portion in the saucepan and cover it with a lid. Let the lasagna simmer for 10-15 minutes, or until it’s heated through.

Tips for Freezing and Reheating Lasagna

Here are some additional tips to help you successfully freeze and reheat your lasagna:

  • Don’t freeze lasagna that has been sitting in the refrigerator for more than four days. The longer the lasagna sits in the fridge, the more likely it is to spoil.
  • Label your lasagna portions with the date and contents. This will help you keep track of what’s in your freezer and how long it’s been there.
  • When reheating lasagna in the oven, you can add a layer of shredded cheese to the top to help it melt and get crispy.
  • Don’t refreeze lasagna that has been thawed. Once lasagna has been thawed, it can’t be frozen again without risking foodborne illness.


So, can you freeze lasagna? The answer is yes, you can freeze lasagna, but you need to do it properly to ensure that it stays fresh and tasty. Consider the factors we’ve discussed before freezing your lasagna, and follow the steps we’ve outlined to freeze and reheat it. With these tips and techniques, you can enjoy delicious lasagna even when you don’t have time to make it from scratch.

Happy cooking and freezing!
