About This Recipe

The preparation begins on the stovetop, where minced garlic is sautéed in butter before being simmered with heavy cream and grated Parmesan. This process creates a stable, concentrated emulsion seasoned with garlic and onion powders to ensure a deep, savory profile throughout the base. As the raw chicken pieces bake directly in this sauce, they release their natural juices, further enriching the cream while the meat remains succulent and tender.

The flavor is characterized by the sharp, salty notes of the Parmesan and the warm, mild spice of the paprika. High-fat dairy provides a dense, mouth-coating richness that replaces the need for traditional starch-based thickeners, allowing the sauce to remain glossy and cohesive. During the final stage of baking, a layer of shredded mozzarella melts into a stretchy, protective topping that browns slightly, adding a toasted finish to the aromatic garlic base.

Typically served hot in deep portions, this casserole is well suited for family dinners or as a reliable centerpiece for weekly meal planning. It retains its creamy consistency and savory depth when reheated, making it a functional choice for those seeking a calorie-dense, low-carb meal. The combination of its straightforward assembly and its refined, steakhouse-style flavor makes it a sophisticated option for a satisfying keto dinner.
