How Long to Reheat Lasagna in Oven? – 3 Easy & Quick Ways

You can have a quick, no-fuss entree any night of the week by reheating your perfect hearty meal – lasagna. It can be even better as leftovers if we properly take time to reheat it. Sometimes we do a lot of hard work for making our delicious lasagna either by making pasta by ourselves or lasagna sauce. So, you can enjoy all of its cheesy decadence for a couple of days by properly reheating in the oven. Now you only need to know how to reheat lasagna in the oven properly and how long to reheat lasagna in oven. You will find all the answers below.

Best Way to Reheat Lasagna

There is no complaint that using the oven is the best preferred method to reheat lasagna. It mimics the actual cooking environment for the casserole. When you take the lasagna out from the normal chamber of the fridge, you will need shorter time. But when you are reheating frozen lasagna in the oven, you need to add more 5 to 10 minutes to the time. 

That means if you want to have lasagna very quickly, put it in the oven for about 20 minutes and reheat it for 350⁰F or above. However, if you want to eat a perfect delicacy, then we will prefer that you keep it in the oven for 40 minutes or more. 

Remember, this reheating lasagna method takes the longest like 30 to 45 minutes, so plan ahead and use it if you have time to spare. 

Step 1: Preheat the oven to 325°F

If you want to enjoy lasagna as good as it was first cooked, you have to be patient about reheating it. If you assume that higher temperatures will cook the lasagna faster, you are wrong.

The hot temperature will steal all the moisture and dry out more quickly than gentle oven temperatures. So, resist the urge to turn up the heat and turn the heat down to 325°F.

Step 2: Cover with aluminum foil

While heating lasagna in the oven, you don’t need to add any extra water. The gentle heat will keep all juices inside and will not dry up the lasagna. All you need to do is cover the casserole dish tightly with aluminum foil to keep all the moisture inside and then pop it in the middle rack of the oven. 

When you are reheating a single piece of lasagna, you can apply the toothpick trick to keep the foil from touching the cheesy upper layer. 

The toothpick trick is quite simple. Take a toothpick and gently stick in the center of the lasagna piece. Remember the toothpick should stick out a few inches. Then, cover the piece, and thus the cover could not touch the melty cheese.  And for reheating whole lasagna or multiple pieces, we should use an oven-proof baking dish covered in foil. 

Step 3: Bake until it’s thoroughly heated

Bake for 30 to 45 minutes and wait until the temperature rises to 165°F in the center.

If you don’t have any grilling thermometer, look at the edges to have a sizzling and melted cheese on top. Or, you can stick a fork in the center. If it comes out warm, then it is done. 

Knowing the minimum temperature is very important to eat healthily. If your leftover isn’t heated properly, then the bacteria in your food have not been eliminated completely. This could cause dangerous circumstances as you eat.
