I was going to change the name of this dish to just ‘spaghetti casserole’ because (before I made it) I thought that calling it Million Dollar Spaghetti was a bit pretentious. Well, as you can tell, I didn’t change the name. That’s because, yeah, Million Dollar Spaghetti is the perfect name for it.

If you close your eyes and take a bite of this spaghetti you’ll almost think you are eating lasagna. Actually, it’s very close in flavor to my mom’s easy lasagna, a recipe I make and devour regularly. Spaghetti sauce, Italian sausage, pasta, a little Italian seasoning and plenty of cheese. What’s not to love?

Million Dollar Spaghetti

Million Dollar Spaghetti was a huge hit in our house. We were sad when the last piece disappeared. But not super sad since we knew it won’t be long until we make this again. And again.

You can easily change this recipe up to meet your own tastes. Maybe add some fresh mushrooms in when you cook the sausage. Or a few bell peppers. For me, a pinch or two of red pepper flake is always a good idea too. You don’t have to use an expensive jarred spaghetti sauce, either. Good ole Prego (I used Italian Sausage and Garlic) works just great!

I highly recommend that you shred or grate your own cheese at home. Don’t buy the pre-shredded or pre-grated stuff. It has stuff added to it to keep it from sticking together. That ‘stuff’ affects how the cheese melts. Shred it yourself and use the good stuff.

To really amp up this dish, use my smoked spaghetti sauce instead of jarred.
