Keto Chicken Broccoli Casserole

This Keto Chicken Broccoli Casserole is the kind of comfort food I never get tired of. Tender broccoli and juicy chicken are topped off a creamy sauce and cheese to create a dish both children and adults are crazy about. This recipe isn't particularly fussy, so feel free to play with it a bit. Cauliflower would work in place of broccoli, and most any cheese will do. You can steam the broccoli instead of blanching it, just make sure you don't over do it to the point that the broccoli gets mushy when baked.
