Preheat your oven to 400°F. Season the chicken breasts with salt, black pepper, and ½ teaspoon of paprika, ensuring an even coating on all sides. Set aside while you prepare the garlic butter mixture.

In a small bowl, combine the melted butter, minced garlic, Italian seasoning, chopped parsley, and the remaining ¼ teaspoon of paprika. Stir well until the ingredients are fully incorporated, creating a rich, aromatic sauce.

Heat a cast iron skillet over medium heat and add the olive oil. Once the oil is shimmering and hot, place the seasoned chicken breasts in the skillet. Sear each side for about 1 to 2 minutes, just until a golden crust forms.

Pour the prepared garlic butter mixture over the chicken, making sure each piece is well-coated. Transfer the skillet to the preheated oven and bake for 20 to 30 minutes, or until the chicken reaches an internal temperature of 165°F.

Once cooked through, remove the skillet from the oven. Before serving, use a spoon to drizzle the flavorful butter sauce from the pan over each chicken breast, ensuring every bite is juicy and infused with garlic butter goodness. Serve immediately.
