Mix everything well to combine.
6
Add the cooked pasta and mix thoroughly.
7
Divide the mixture between two casserole dishes that have been sprayed with non-stick cooking spray.
8
Open the can of Frenchs fried onions and pour into a small ziploc bag crush until theyre the consistency of breadcrumbs.
9
Sprinkle the remaining 1 cup of cheese and the crushed fried onions evenly between the two casseroles.
10
Bake for 20-30 minutes until the cheese has melted and the edges are bubbling.
