how long to bake lasagna at 400

The baking time for lasagna at 400°F (200°C) can vary depending on the size of the dish, the number of layers, and the type of cheese used. Here are some general guidelines:

* Small lasagna (6-8 inches square, 2-3 layers): 25-35 minutes
* Medium lasagna (8-10 inches square, 3-4 layers): 35-45 minutes
* Large lasagna (10-12 inches square, 4-5 layers): 45-55 minutes
* Extra-large lasagna (12 inches square or larger, 5-6 layers): 55-65 minutes

It’s also important to check the lasagna for doneness by looking for the following signs:

* The cheese is melted and bubbly
* The edges are golden brown
* The lasagna is hot and steaming when you insert a knife or fork

To ensure the lasagna is cooked through, you can also check the internal temperature. It should reach 165°F (74°C) in the center of the dish.

Remember to cover the lasagna with aluminum foil for the first 30 minutes of baking to prevent the cheese from burning. Remove the foil for the remaining baking time to allow the cheese to brown and bubble.
