Preheat Oven: Preheat your oven to 375°F (190°C). Grease an 8x8-inch baking dish or similar-sized casserole dish to prevent sticking.
Prepare the Creamy Mixture: In a large mixing bowl, combine the room-temperature cream cheese and heavy cream. Stir until smooth and well blended.
Add Seasonings and Cheese: Add the herb and garlic seasoning (or Italian seasoning), salt, and half of the shredded cheese to the cream mixture. Mix the ingredients thoroughly until everything is well blended.
Assemble the Casserole: Add the shredded rotisserie chicken, frozen cauliflower rice, and chopped bacon to the bowl. Mix everything until the cauliflower rice and chicken are fully coated in the creamy sauce.
Transfer to Baking Dish and Top with Cheese: Transfer the mixture to the prepared baking dish, spreading it out evenly. Top with the leftover shredded cheese and spread it evenly.
Bake the Casserole: Place the casserole in the preheated oven and bake for 20–25 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.
Serve and Enjoy: Remove the casserole from the oven and allow it to cool slightly before serving. Garnish with fresh herbs if desired, and enjoy this hearty keto-friendly meal!
