One-Pan Chicken Florentine Spaghetti Bake

This is about simplifying your day!

There’s very little prep work here ~ it’s a no fuss dish:  dry pasta, uncooked chicken, your favorite sauce, all blanketed with mozzarella cheese. 

To begin, break raw uncooked spaghetti in half, or thirds, over a layer of your favorite sauce; homemade or jarred, in a casserole baking dish. 

Cut the chicken into bite-size chunks and spread over the top, along with mushrooms and spinach.  Do this in two layers, finishing with mozzarella sprinkled over the top, then bake for an hour or so. 

That’s it!  One-pan, no fuss, little clean-up and a delicious comforting dinner for you and your family on a chilly day like it is here today!

It doesn’t get much easier!
