How Long to Cook Lasagna in Oven


I love lasagna. It’s the ultimate comfort food, and it’s easy to make if you have a few hours to spare. In fact, I always use my slow cooker to cook lasagna because it requires much less attention that way than using an oven would. But what do you do if you don’t have all day? Luckily there is a solution! You can still enjoy your favorite dish even if you’re short on time by cooking it in the oven at 350 degrees F for 1 hour 15 minutes instead of simmering it on low heat all day long. Here are some tips for how long to cook lasagna in your oven:

Preheat oven.

To preheat an oven, you’ll need to set it to the desired temperature and allow time for it to reach that temperature. If you don’t do this, your lasagna will take longer than expected to cook–and may be undercooked or overcooked when you remove it from the oven.

To preheat an oven:

  • Set your oven dial to 400 degrees Fahrenheit. If you want a higher temperature (say 450), set your dial accordingly then turn on all burners on high heat for 5 minutes before turning them off again; this will help get things going faster when you put food into them later on in preparation for cooking!
  • Place any dishes containing warm ingredients like tomato sauce or cheese directly onto countertops so they can come up to room temperature while heating up their surroundings as well as themselves; otherwise they might cool down too quickly once placed inside hot ovens later on during cooking times.”

Prepare your lasagna pan.

Prepare your lasagna pan.

Use a 9×13 inch pan, greasing it with butter and dusting with flour or spraying it with nonstick spray. If you have a nonstick pan, this will work even better!


Layer in ingredients, beginning with sauce and ending with cheese.

  • Spread a layer of sauce across the bottom of your baking dish.
  • Add a layer of ricotta cheese, followed by mozzarella and parmesan cheeses in that order (the latter two are optional but highly recommended).
  • Top with uncooked lasagna noodles, making sure there’s enough sauce to cover them completely; if not, add more until they’re fully submerged in it.
  • Repeat steps 1-3 until all ingredients are used up or your heart desires stop!

Cover with foil or a lid and bake for 1 hour 15 minutes.

Covering the lasagna with a lid or foil helps to keep it moist, which is especially important if you’re cooking it at a lower temperature. Make sure that your lid isn’t too tight, as this will make it harder for steam to escape and could cause your lasagna to be watery.

Bake for 1 hour 15 minutes; then remove from oven and let stand for 10 minutes before serving (this will allow some of the liquid from inside your pan to evaporate). You can cook this dish longer than 1 hour 15 minutes if needed–but don’t cook it any shorter than that!

A lasagna cooked in the oven should be allowed to cool before being cut into slices, otherwise it will be very difficult to cut through.

A lasagna cooked in the oven should be allowed to cool before being cut into slices, otherwise it will be very difficult to cut through. If you try cutting it while it’s hot, your knife will just bounce off of the lasagna and make a mess of things.

The best way to avoid this is by allowing your dish time to cool down after baking or cooking it.


So there you have it! The best way to cook lasagna in the oven. If you want to make sure your lasagna comes out perfect every time, be sure to follow these tips and tricks for making sure your dish does not stick or burn while baking.
