Easy Chicken Marinara Casserole

I know it is cliche, but we love a good casserole.  I think it’s because I am from the casserole capital of the world (Minnesota). The beauty of a casserole is in its simplicity.  You can typically prepare them in advance and pop them in the oven when you are ready to eat. This recipe is no exception. With just a few simple ingredients, you can have a hearty and tasty meal on the table.

How to Make Easy Chicken Marinara Casserole

This is one of those meals that is as easy to make as it is delicious. It starts with the seasoned shredded chicken. In a large bowl, add salt, pepper, and garlic powder to the cooked chicken. Spread the chicken out on the bottom of a 9×13-inch baking dish that has been sprayed with nonstick spray.

On top of the chicken, pour the jar of marinara sauce. Next, add the Italian seasoning and both kinds of cheese. Top it off with the crushed red pepper flakes and bake the casserole for 30-35 minutes, or until the cheese is bubbly. If you are not big on spiciness, just leave out the crushed red pepper flakes. Serve with a basket of Garlic Breadsticks and a side of  Roasted Parmesan Green Beans.

Can I Make this Meal Ahead of Time?

Yes! That is what is so nice about casseroles; many of them can be made ahead of time and frozen until you are ready to eat them. In this recipe, layer all of the ingredients in the pan and cover it with plastic wrap and aluminum foil. Try to get as much air out of it as you can. Label and date the container; it will freeze for up to 3 months. 

When you are ready to bake the casserole, let it thaw in the refrigerator overnight and bake it according to the instructions. If it still a little frozen, just bake it a little longer.
