Creating this incredible Creamy Chicken Bake is straightforward. Just follow these steps for success:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Chicken: Cut the chicken breasts into bite-sized pieces. Season them with salt, pepper, garlic powder, onion powder, and paprika.
3. Sauté the Chicken: In a large skillet, heat the olive oil over medium-high heat. Add the seasoned chicken and cook until golden brown, about 5-7 minutes.
4. Add Vegetables: Once the chicken is browned, add the broccoli florets or your choice of vegetables into the skillet. Stir to combine and cook for an additional 2-3 minutes.
5. Mix the Sauce: In a separate bowl, combine the sour cream and cream of chicken soup. Stir until smooth and mixed well.
6. Combine Ingredients: Pour the creamy sauce over the chicken and vegetables in the skillet. Mix gently until everything is evenly coated.
7. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish.
8. Add Cheese and Breadcrumbs: Sprinkle the shredded cheese evenly over the top of the chicken mixture. Then, sprinkle breadcrumbs on top for an added crunch.
9. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the cheese is melted and bubbly, and the edges are slightly golden.
10. Let It Cool: After baking, let the dish cool for a few minutes before serving. This allows the sauce to thicken slightly.

By following these steps, you will create a comforting and fulfilling Creamy Chicken Bake that everyone will love.
