Add in the marinara sauce and stir. Take the pan off the heat.
24 ounces marinara sauce
In a bowl, combine the ricotta, 1½ cups mozzarella cheese, parmesan cheese, chopped herbs, egg, ½ teaspoon salt, and pepper.
15 ounces whole milk ricotta cheese, 3½ cups freshly shredded mozzarella cheese, ½ cup freshly grated parmesan cheese, ¼ cup chopped fresh parsley and/or basil, 1 large egg, ¼ teaspoon ground black pepper
Spread a thin layer (about ½ cup) of the meat sauce on the bottom of the prepared baking dish.
Spread 3-4 tablespoons of the cheese mixture over the each lasagna noodle.
Then, spread 2-3 tablespoons of the meat sauce over the cheese mixture.
Roll the lasagna noodles up, and place them, seam side down, in the casserole dish.
Pour the remaining meat sauce over the lasagna rolls, and top with the remaining mozzarella cheese.
Cover your lasagna pan with foil. Ensure the foil does not touch the cheese.
Bake for 20 minutes. Then, remove the foil, and bake for another 10-15 minutes until the edges are browned. If desired, broil the lasagna for 1-2 minutes to get the tops extra toasty.
