Place the top oven rack in the center position and set temperature to 375°F.
In a large glass bowl, combine ricotta cheese, beaten egg, 3 tablespoons Italian seasoning, and fresh parsley. Stir to combine.
Spray a 13 x 9” glass baking dish with non-stick cooking spray.
Add enough meat sauce to cover the bottom of the pan and then cover with 3 lasagna noodles.
Top with an even layer of the ricotta cheese mixture, followed by a layer of shredded mozzarella and Gruyère cheese, using equal amounts of each.
Finish with a layer of grated Parmesan and Asiago cheese, also in equal amounts.
Repeat this process three more times: meat, noodles, ricotta mixture, shredded cheeses, and grated cheeses.
Sprinkle the remaining Italian seasoning across the final layer.
Loosely cover with aluminum foil and bake for 30 minutes.
Remove foil and continue baking for another 20-25 minutes.
Remove from oven and allow to rest for 20 minutes before slicing and serving. Enjoy!
