If you would like to heat up your lasagna, return it to the oven at 350 degrees F, 180 degrees C, for 10 minutes.

At the end of the cooking time, you will broil the lasagna for one to two minutes to allow the cheese to bubbly up at the top. There will be 2 minutes of broiling once it is baked, so that the cheese on top is nicely browned and bubbly. If you take the lasagne out at about 20 minutes, the cheese has finished melting and is beautifully browned. Then, pour the sauce of your choice on top of your finished lasagna and let cook for a couple minutes.
The lasagna will take at least 5 hours to chill and let the sauce loosen up the noodles, but you can prepare your lasagna the night before (or even 3 days before) and bake it whenever you need to. The best made-ahead lasagna needs at least 5 hours to chill and allow one awesome homemade tomato sauce to soften the noodles, but you can certainly make it the night before–or even 4 days before–and bake it when you need it. You do not have to bake one pan of lasagna ahead (otherwise, you are going to end up baking it twice). If you would rather, you can allow the lasagna to cool a bit before serving.
The layers will have all set, and your lasagna can be heated up without worrying about breaking. The absolutely best way to heat up leftover lasagna from the freezer is by placing it into a baking-safe bowl, adding about 2 tablespoons of water, and covering with aluminum foil. When baking, you will want to cover the lasagna with foil for the last 20 minutes of baking.
At 350 degrees F, let your lasagne made with the noodles that have been prepared for cooking sit in the oven 30 to 45 minutes, covered with aluminum foil, and slightly tented to prevent contact between it and the noodles or the sauce. If baked covered with foil and made with cooked noodles, it will take about 30-45 minutes to fully cook your lasagna in a preheated 350degF oven, but if made using uncooked noodles, it will take 45-60 minutes to bake at 350degF. If you are not using no-boil noodles for your lasagna, simmer noodles until halfway done before baking, since the noodles will continue cooking in the oven while being bathed in the sauce.
If you have normal boiling-first types of noodles, you will have to cook them and strain them before baking. You should use caution here so that you do not overuse sauce, which can lead to a watery lasagna. If using the non-boiled noodles, you will need to use some additional sauce. The non-boiled noodles can soak up extra moisture as they bake, so plan accordingly. Re-run through the process!After laying the second sauce layer, add another noodle layer, followed by your seasonings, cheese, and another layer of sauce.
The pre-cooked noodles should be just barely al dente, since they will continue cooking for 40-60 minutes as your lasagna is baking. If you notice your lasagna is getting browned too much on top before the noodles are cooked, you can lower your heat slightly and extend your baking time a few minutes. If using dried noodles, make sure you cook them according to the directions on the package before you put together your lasagna.
Depending on your method of cooking, the amount of time your Lasagna takes to bake depends on when you place your sheet of dough into the pan.
