Prep the chicken: Pat the chicken breasts dry with a paper towel and cut them into 1-inch pieces.
Season the chicken: In a bowl, sprinkle the flour, oregano, basil, paprika, salt, and pepper over the chicken. Toss to coat evenly.
Heat the pan: Warm a cast iron skillet over medium-high heat. Add the olive oil and 1 tablespoon of butter.
Cook the chicken: Once the butter is melted, arrange the chicken in a single layer. Cook undisturbed for 3 minutes until golden on one side. Flip and cook another 2 minutes.
Add garlic and parsley: Stir in the remaining butter, garlic, and parsley. Cook for an additional minute, allowing the flavors to meld and the chicken to reach full doneness.
Serve hot: Enjoy immediately as is, or pair with your favorite sides like rice, pasta, or a crisp green salad.
