Keto/ Low Carb Fiesta Chicken Casserole

This chicken casserole is the perfect way to use up leftover or chicken, or a Rotisserie chicken for a quick & easy dinner recipe. This chicken casserole takes just 10 minutes to prep, its packed with cheesy Tex-Mex flavors, and is an easy meal prep idea or weeknight dinner.

I am a big believer in easy casseroles. Maybe because they are so effcient (everything in one place), maybe because you can pretty much add any kind of meat and top any casserole with cheese…whatever the reason is, I am onboard with a casserole recipe. AND if you can somehow get Tex-Mex flavors in there as well, it’s basically the perfect meal!

I use Cream of Chicken soup in this casserole. I make my soup and always keep it in my fridge for an easy grab and create kind of thing. Click on this link for the easy recipe.
