Is it better to cook lasagna covered or uncovered?
It is best to cover the lasagna when cooking. Cover the lasagna with foil for most of the cooking time to prevent it from drying out and ensure even cooking. Remove the foil towards the end to allow the top to brown, bubble properly, and get a nice crispy texture.

The foil helps distribute heat evenly, ensuring the middle of the lasagna cooks thoroughly before the top gets too brown. It also prevents the cheese from burning on top while the lasagna cooks.
What is the best way to ensure your homemade lasagna doesn’t dry out when cooking in the oven?
The best method to prevent your lasagna from drying out while baking is to use enough sauce in each layer, pre-cook the pasta noodles, cover the dish with foil while baking to trap moisture, and consider adding a creamy béchamel sauce to your layers; this will help the noodles absorb liquid and keep the lasagna moist throughout cooking.
Here are some key tips to ensure your homemade lasagna doesn’t dry out when cooking in the oven.
1. Don’t skimp the sauce.
Don’t skimp on the sauce, ensuring a generous amount is spread between each layer of pasta and cheese.

3. Cover with foil
To retain moisture, use aluminum foil to cover your lasagna during baking.
4. Add béchamel sauce
