Keto Creamy Chicken and Vegetable Bake

Preheat the oven to 350 degrees F (175 degrees C).

Heat 1 tablespoon butter over medium heat in a large pot. Add bacon, onion, and garlic; cook until onion is soft, about 5 minutes. Add chicken and cover the pot. Cook until chicken is no longer pink in the centers, stirring occasionally, about 10 minutes.

Stir in broccoli, cauliflower, leek, mushrooms, chicken stock, and garlic and herb seasoning. Replace the lid and cook until vegetables are soft, about 10 minutes.

Meanwhile, heat a saucepan over medium heat. Add remaining butter and heavy cream and heat through, 2 to 3 minutes. Add cream cheese and cook until melted, stirring often, 3 to 4 minutes. Remove sauce from heat. Stir in Parmesan cheese.

Drain and discard excess liquid from chicken mixture, if necessary. Transfer mixture to a large baking dish. Pour sauce on top and add grated Cheddar cheese.

Bake in the preheated oven until cheese is melted and browned to your liking, about 10 minutes.
