How to cook frozen lasagna faster

Lasagna is a staple comfort food in many places. It can take a long time to prepare, so we often make two at a time and freeze one for later.

That’s great because when we need a quick fix, we can just pop out the frozen lasagna and cook it and have a delicious dish without the lengthy prep time.

Lasagna can take a long time to cook when thawed, so cooking it from frozen really does take some time. You have to plan the cooking time or find alternative ways to cook it and speed up the cooking process without ruining the dish.

How can you cook frozen lasagna faster? The best way to cook frozen lasagna faster is to start cooking it with a foil cover. Although it’s best to thaw the lasagna first, you can bake it from frozen using this method. However, it will still take quite a while.

Cooking frozen lasagna is absolutely doable and it really is quite simple. If you want to cook it without defrosting it, no problem. You will probably need to plan for about 90 minutes of cooking if you are going to bake it from the frozen state.

Whether you cook the lasagna fresh or thawed, it will probably take about 60 minutes , so you’ll have to wait quite a while either way.

However, it saves you the trouble of having to remember to defrost it.

If your lasagna is extra large, you may need 20 minutes more than the time indicated here.

You can also cook it a little faster if you have a convection oven . We recommend a high temperature so that the juices really cook.

How to quickly cook frozen lasagna

Here are the steps to cook frozen lasagna as quickly as possible:

  1. Take the lasagna out of the freezer and preheat the oven to 400 degrees .
  2. Cover the lasagna dish with aluminum foil so that it is well covered. This will allow it to cook and warm through the frozen parts without burning the cheese on top.
  3. Bake the lasagna covered for about 60-75 minutes .
  4. Remove foil and continue baking until sauce is bubbly and cheese is melted and golden. This should be approximately 30 minutes.
  5. Let cool slightly and serve and enjoy.

Keep in mind that if your lasagna is in a glass dish, you need to defrost it first before putting the glass dish in the oven. You can do it in the microwave if you absolutely have to.

Should you thaw frozen lasagna first?

As you can see in our process above, it is absolutely possible to cook your frozen lasagna without thawing it first.

However, we recommend that you defrost the lasagna if you really want the cooking process to be fast, but it is not necessary.

To defrost, you have a couple of different options.

You can take the lasagna out and put it in the fridge overnight. This is probably the easiest option to have your lasagna thawed and ready to heat up for dinner. You do not have to do anything else.

Remember that if your lasagna is in a glass container , you definitely need to thaw it and this overnight thawing process is probably the best way to do it.

However, you can also use the microwave to defrost , as long as you don’t have aluminum foil or metal in the pan.

If you decide to use the microwave’s defrost function, keep in mind that you should check the lasagna often, as you don’t want the microwave to start cooking the lasagna for you. That job belongs to the oven!


While there isn’t necessarily a super-fast way to cook frozen lasagna, there are a few things you can do to make the process go smoothly.

You should expect a cooking time of about 90 minutes total for a frozen lasagna. A thawed lasagna will take about 60 minutes to cook.

The fastest way to cook frozen lasagna is to thaw it first, but you must remember to take it out the night before or take the time to defrost it in your microwave. You can also cook it a little faster in a convection oven.
