Homemade Chicken Spaghetti Casserole

Homemade Chicken Spaghetti Casserole

Are you ready for Winter with piles of snow and cold cold weather? I grew up where some winters were at 40 below zero! What kind of comfort food do you fix in the winter? We love soups and casseroles and loaves of warm bread.

I remember coming home and my mother was taking homemade bread out of the oven and she had a big pot of soup cooking on the stove. She would make all kinds of cookies and raisin-filled were my favorite.

We are suppose to have a blizzard today so I am looking for a recipe to make with food I have in my kitchen to make for dinner. I have some leftover chicken and this Homemade Chicken Spaghetti Casserole is filling and always makes my family ask for seconds. They will be excited to see this on the table!

Casseroles are the ultimate comfort food. It reminds me of growing up at home and holds lots of memories. As you get older and married you bring all that food into your own families. Comfort food makes us happy.

Chicken Spaghetti Casserole is so easy to put together. Within 30 minutes you have a dinner that your family is going to love.

We like to serve a green salad and some warm french bread with this meal. A fruit cup or cobbler would be good.

Super delicious, comforting, and perfect for feeding your family any day of the week.
