How Long Does Lasagna Take to Cook


You’ve been craving lasagna for what feels like forever, so you finally decide it’s time to start cooking and slicing. You have all the ingredients out on your counter, but an hour later—after you’ve already eaten dinner—you’re still not done with this bad boy. “How long does lasagna take to cook?” you ask yourself as you stare at your timer and wonder why this thing isn’t working. It turns out that there are a lot of variables involved here: How big is your pan? What kind of oven do you have? Is it gas or electric? These questions can make things tricky when it comes to determining how long it’ll take for your dish of choice to properly come together. Lucky for us, we’ve got answers! Here’s everything you need to know about making lasagna:

Prep Time

The first thing you’ll want to do is get all the ingredients out and ready. This means washing and cutting up your vegetables, pre-cooking any meat that needs it (such as ground beef), and preparing any sauces. It may sound like a lot, but once you start cooking lasagna, everything will go by quickly!

Boil the lasagna noodles.

In a large pot, bring water to a boil. Add the lasagna noodles and cook for 8-10 minutes, until al dente. Drain the cooked noodles in a colander and set aside.

Place the lasagna into the oven.


  • Place the lasagna into the oven.
  • Make sure to set your oven to 350 degrees Fahrenheit, and make sure it’s preheated!
  • Place a baking sheet in the middle of your oven, then place your assembled lasagna on top of it (this will keep it from sticking). Cover with aluminum foil and bake for 45 minutes or until bubbling hot throughout. Remove from heat once done cooking; let cool slightly before serving.

Cooking time.

The cooking time varies depending on the type of lasagna and the oven temperature. The higher the temperature, the faster your lasagna will cook; conversely, if you set your oven to a lower temperature–say 350 degrees F–your dish may take longer to bake. In general, though, keep in mind that when making homemade lasagna:

  • Set your oven temperature at 350 degrees F
  • Use enough cheese and sauce to fill each layer (there should be no dry spots)

Remove from the oven and allow to cool for at least 10 minutes before cutting.

Once you’ve removed the lasagna from the oven and allowed it to cool for at least 10 minutes, cut into serving-sized portions. Do not slice through your lasagna while it is still hot–you’ll burn yourself! How long this takes depends on how hot your lasagna was when you removed it from the oven, but generally speaking, if your knife doesn’t melt after a few seconds’ contact with the dish then it’s probably safe to go ahead and eat (or at least try).

No one wants to burn their mouth on hot, fresh-cooked lasagna!

Let it cool for at least 10 minutes before you cut into it. After all, who wants to burn their mouth on hot, fresh-cooked lasagna? You can use a knife or pizza cutter to make the first slice. If you’re using an electric knife, be careful not to cut yourself! It’s also helpful if you have two people working on this step–one person can remove pieces from the pan while another person cuts them into smaller pieces.

If there are leftovers after dinner (and there probably will be), cover them with aluminum foil and refrigerate them within 2 hours of cooking time so they don’t get soggy when stored overnight in the fridge.


When you take the time to prepare lasagna, it’s worth it! Not only do you get to enjoy delicious food, but you also get to spend time with your friends and family. And if there are leftovers? Well then they can be eaten for breakfast or even lunch the next day!
