This keto chicken casserole is loaded with tender chicken, spinach, leeks, and cheesy goodness! It’s an irresistible family dinner you’ll make again and again.
A cheesy casserole combined with tender chicken, bacon, leeks, and spinach in a deliciously cheesy sauce.
While it’s best enjoyed freshly cooked, you can easily prepare and mix all of the ingredients ahead of time in a pan. When you’re ready, pop it in the oven to bake to save time.

We used mozzarella cheese but feel free to use cheddar, edam or gouda cheese instead. They melt just as well and turn golden brown and bubbly in the oven!
