Million dollar spaghetti casserole is an ooey-gooey comfort food. And easy to use up those leftovers from Spaghetti dinners. Literally It was left over spaghetti, meat sauce, a jar of mozz cheese sauce or you can use mozz , ricotta for that layer.
Grease a casserole dish
Toss the pasta and sauce together and put that layer in.
Next you want a cheese layer- your choice, I like to ad a jar of the mozzarella cheese sauce.
Next layer a healthy layer of meat sauce, in my case I had left over meatballs do crumbled them and some sauce.
Topped that with grated cheese and a few Pepperoni's.
Bake 350 for about 40 minutes
Top-notch let sit for 15 minutes before serving.
