01 - Preheat the oven to 400°F. Lightly grease a medium-sized baking dish with cooking spray or butter.
02 - Heat a large skillet over medium heat. Add diced chicken and cook until no longer pink, about 5–6 minutes. Remove from heat and set aside.
03 - In the same skillet, sauté minced garlic for 1 minute until fragrant. Add broccoli florets, diced zucchini, and red bell pepper. Cook for 3–4 minutes until slightly tender.
04 - In a mixing bowl, whisk together heavy cream, softened cream cheese, shredded cheddar, grated Parmesan, dried thyme, smoked paprika, salt, and black pepper until smooth and creamy.
05 - Combine cooked chicken, sautéed vegetables, and cream sauce in the prepared baking dish. Mix thoroughly to ensure all ingredients are evenly coated.
06 - Transfer to the preheated oven and bake for 25 minutes until the sauce is bubbly and the top is golden brown.
07 - Remove from oven and sprinkle with chopped fresh parsley before serving, if desired. Serve hot alongside a simple green salad.
