Today we are making 5 of my favorite comforting casseroles. These are perfect for chilly evenings, weekend dinners with family and friends, or even to make ahead for a busy weeknight meal. They freeze really well, and are the epitome of comfort food! We will be making my Apple Sausage Mac & Cheese, French Onion Chicken Casserole, Reuben Casserole, Chicken Parmesan Casserole, and Classic Shepherd's Pie.
