If you’ve ever baked lasagna, you must know that it’s quite tough to determine the exact time it needs in the oven. The best-baked lasagna requires sufficient heat to cook it through. While blending all the flavors, but not too much heat to burn or overcook the pasta.

So, if you’re wondering how long you should bake lasagna at an ideal temperature of 350 degrees Fahrenheit; this article is for you.

How Long to Bake Lasagna at 350?

Well, the answer isn’t that straightforward.

How long you should bake lasagna depends on many factors. Such as its overall size, how many layers it has, the amount of moisture in its main components, etc. In addition, how long will the pasta layers, vegetables, meat, and other elements take to fully cook? (although they have been previously cooked in a pan) as all of the cheese melts into them. 

So factoring in all these aspects, the average bake time for lasagna is about 45 minutes in a preheated oven.

Also, remember that preheating and baking temperatures may vary for conventional and convection ovens. So be sure to find a recipe that meets your requirements.

Tips for Cooking the Perfect Lasagna at 350

So now that we know the basic temperature requirement; let’s dive into the details of baking amazing lasagna at the right temperature.

  • Once you’ve layered and assembled your lasagna in a baking dish, wrap an aluminum foil around it and bake it in a preheated oven at 350 degrees Fahrenheit for about 45 minutes.

Just in case you were curious, 350 degrees Fahrenheit is the best oven temperature for baking lasagna because it provides the right amount of heat to warm the sauce, melt the cheese, and cook the noodles without burning anything.

  • Remove the foil and bake for another 15 minutes to get that crispy/crusty top layer and edges.
  • Insert a toothpick into the lasagna to ensure the noodles are fully cooked. If it goes through easily and doesn’t show resistance, you’re good to go. Also, once the sauces start bubbling around the edges of the baking pan, it’s time to remove the lasagna from the oven.
  • Let the lasagna rest for about 15 minutes before slicing into it.

Here’s an interesting tip for you: If you’re looking for a way to save some time and effort, use no-boil noodles! Not having to boil noodles for the lasagna takes at least 10 minutes off your recipe and reduces the baking time. But remember to add more sauce than usual to the lasagna since these noodles absorb more moisture than regular noodles.

Should You Bake Lasagna Covered or Uncovered?

So this is another debate you might find between recipes. And to be honest, it’s mostly a matter of taste and appearance.

Baking the lasagna uncovered might make it dry and overcooked. That’s why most recipes generally instruct to bake lasagna after covering it with aluminum foil. Once it’s baked halfway through, i.e., for about 30 to 35 minutes, remove the foil to bake the top for another 15 minutes as mentioned above.

However, if you don’t mind reasonably moist lasagna and you’re not into the golden brown crusty top layer, just bake the lasagna uncovered for 45 minutes, and you’re done.

How Long Should You Bake Refrigerated Lasagna?

It’s a no-brainer that refrigerated lasagna will take a higher temperature and longer time to cook since nobody likes lasagna that’s stone-cold in the center!

Preheat the oven to 400 degrees Fahrenheit before baking refrigerated lasagna. Bake lasagna for at least 40 to 50 minutes in an 8-inch square pan, 55 to 70 minutes in a 9-inch by 13-inch pan, and 70 to 85 minutes in a jumbo-sized pan.

How Do You Reheat Leftover Lasagna in the Oven?

To reheat refrigerated lasagna, cover it with aluminum foil and bake it in a preheated oven at 325 to 350 degrees Fahrenheit for about 3-5 minutes, or until it is well heated.

You can also use a microwave to reheat refrigerated lasagna. Place a slice of lasagna on a microwave-safe plate and give it about 2-3 minutes in the microwave at high heat till it is heated through. Remember to cover the lasagna with a paper towel or microwave-safe cover to avoid splatters.
