Keto Creamy Spinach Artichoke Chicken Casserole

This Keto Creamy Spinach Artichoke Chicken Casserole takes everything people love about warm spinach-artichoke dip and transforms it into a hearty, fully satisfying low-carb dinner. Tender pieces of chicken are folded into a rich mixture of cream cheese, mozzarella, parmesan, garlic, spinach, and artichoke hearts, creating a perfectly creamy texture without needing flour or starches. The casserole bakes into a bubbly, golden top while staying unbelievably moist underneath, giving every bite a mix of melted cheese, savory chicken, and tangy artichoke flavor. It’s a simple weeknight recipe that uses common keto staples, delivers maximum comfort-food vibes, reheats beautifully for meal prep, and fits effortlessly into any low-carb lifestyle.

About This Recipe

If you love the flavor of spinach-artichoke dip, this casserole takes everything indulgent about that iconic appetizer and turns it into a full dinner without adding a single gram of unnecessary carbs. The creamy base melts into the chicken while baking, giving you that rich, velvety consistency that feels like comfort food without being heavy or greasy. It’s the perfect balance of cheesy, savory, tangy, and hearty — all in one dish.

The magic comes from how well the ingredients work with keto staples. Cream cheese keeps the sauce thick and luxurious, mozzarella adds pull-apart meltiness, and parmesan gives a sharp, salty finish that ties the whole dish together. The artichokes bring brightness and acidity, while the spinach adds volume and nutrients without affecting carbs. Nothing tastes watered down or “diet” — it’s a fully satisfying, restaurant-style casserole.

Another reason this recipe shines is the convenience. Everything comes together in one bowl before being baked, which means minimal dishes and maximum payoff. It’s also extremely forgiving: whether you use rotisserie chicken, leftover meal-prep chicken, or pan-seared chicken breasts, the casserole always turns out creamy and flavorful. It reheats well, freezes well, and makes for an ideal low-carb dinner when you don’t want to spend an hour in the kitchen.

Visually, it’s as inviting as it is delicious. The top turns golden and slightly crisp, contrasting with the soft, creamy interior. Serve it on a clean, simple plate, and it instantly looks like a cozy, homemade comfort meal worth savoring any night of the week.
