Yes! Overcooked lasagna will become dry, and the noodles may brown around the edges and turn crispy. Homemade lasagna needs to cook at 350 degrees for about 45 minutes. But, you can start checking for doneness around 35-45 minutes as ovens vary. Lasagna is done when it reaches an internal temperature of at least 165 degrees. You can also check for doneness by inserting a toothpick or fork into the center of your lasagna. If it comes away clean, it's ready to eat. Your lasagna may also be ready if the top layer of the lasagna is golden brown, the sauce bubbles up around the edges of the pan, or you taste test a small portion of the lasagna and it is warm all the way through.
