Follow these simple steps to prepare the Best Ever Chicken and Rice Casserole:

1. Preheat Your Oven: Start by preheating your oven to 375°F (190°C).
2. Cook the Chicken: Heat the olive oil in a large skillet over medium heat. Add the chicken breasts and season with salt, pepper, and paprika. Sear until golden brown, about 5-7 minutes per side. Remove from heat and set aside.
3. Prepare the Base: In a large mixing bowl, combine the uncooked rice, cream of chicken soup, chicken broth, frozen mixed vegetables, chopped onion, and minced garlic. Stir well to combine.
4. Layer the Ingredients: In a greased 9×13 inch baking dish, spread the rice and vegetable mixture evenly across the bottom.
5. Add the Chicken: Place the seared chicken breasts on top of the rice mixture, ensuring they are evenly spaced.
6. Cover and Bake: Cover the baking dish with aluminum foil, then place it in the preheated oven. Bake for 30 minutes.
7. Remove Foil: After 30 minutes, remove the foil and bake for an additional 15 minutes, allowing the dish to become slightly crispy on top.
8. Check for Doneness: Ensure the chicken is cooked through—internal temperature should reach 165°F (75°C).
9. Garnish: Once done, remove from the oven. Let it rest for a few minutes before garnishing with fresh parsley, if desired.
10. Serve: Dish out servings and enjoy the warm, comforting flavors.
