A creamy, cheesy low-carb chicken Alfredo bake with cauliflower and homemade Alfredo sauce, ready in 40 minutes and perfect for weeknight dinners or meal prep.
Preheat your oven to 375°F and grease an 8x8 baking dish.
Heat a large skillet over medium heat and melt the butter. Add the minced garlic and saute for 1 minute until fragrant. Add the chicken pieces, season with salt, pepper, and Italian seasoning, and cook until no longer pink, about 6 to 8 minutes.
Lower the heat and pour in the heavy cream, stirring constantly. Add the grated Parmesan and continue stirring until the sauce thickens slightly, about 3 to 4 minutes.
In a large mixing bowl, combine the steamed cauliflower, the cooked chicken with all its Alfredo sauce, and 1 cup of the shredded mozzarella. Stir until everything is evenly coated. Taste and adjust seasoning.
Transfer the mixture to the greased baking dish and spread it out evenly. Sprinkle the remaining mozzarella over the top.
Bake uncovered for 20 minutes until the cheese is bubbly and golden brown on top.
Remove from the oven and let rest for 5 minutes. Garnish with chopped fresh parsley before serving.
