How to Make Keto Chicken Alfredo Casserole
This is a brief overview; see the recipe card below for exact measurements and full instructions.
Start by making the alfredo sauce on the stovetop and set it aside—the sauce will thicken as it cools. Preheat the oven to 350°F while you assemble the casserole. In a 7″ x 11″ (or similar) casserole dish, place the cubed cooked chicken and pour the warm alfredo sauce evenly over the top.

Layer shredded mozzarella and grated Parmesan over the sauced chicken, then sprinkle finely crushed pork rinds for a crunchy, low-carb topping.

Bake on the center rack for about 25 minutes until the cheese is melted and bubbly and the pork rind topping is golden brown. Remove from the oven, let it rest briefly, then serve and enjoy.

If you crave fettuccine, use konjac-based “Wonder Noodles” for a net-carb-free option. Rinse them thoroughly, warm briefly, and mix them into your portion of casserole or serve them underneath the baked chicken and sauce.
