Set your oven to 350°. While it is warming up, chop your onions and fry them in the 2 T. butter until thay are a little browned.

Add to the onions, everything except for the mozzarella cheese and lasagna noodles. Incorporate everything well. Continue to cook for a couple of minutes.

Grease a 10×13 pan, then spoon a little of the Alfredo mixture onto the bottom of the pan. Lay three pieces of lasagna noodles in the pan, spoon a layer of Alfredo sauce, add a layer of mozzarella, then noodles again. keep layering with noodles, sauce, cheese. Make sure you stop with a layer of sauce and cheese on top. :)

Top your Alfredo Lasagna dish with aluminum foil and bake for 35 minutes. Remove foil and bake another 5 minutes.
