Spaghetti Casserole

Kimberly Kay


This is a little bit of a twist on traditional spaghetti that I found on Allrecipes. Although the original recipe didn't call for it, I added one pound of ground sirloin.

I also substituted Cottage cheese for the Ricotta and substituted grated Parmesan cheese for the shredded kind.
