Heat 1-1/2 tablespoons vegetable oil over medium-high heat in a large skillet.

Pat dry the chicken breasts with paper towels.

Drizzle a bit of oil over each chicken breast, or spray with cooking oil, and rub it all over.

In a small mixing bowl, combine salt, pepper, garlic powder, onion powder, basil, and paprika.

Season both sides of each chicken breast with the prepared seasoning; rub it all around.

Add 2 chicken breasts to the hot skillet and cook for 5 to 7 minutes without moving them.

Flip both chicken breasts over, add 1 tablespoon of butter to the skillet, swirl butter around, and continue to cook for 7 more minutes, or until the internal temperature reaches 165F.

Remove chicken breasts from the skillet; set aside and keep covered.

Repeat the same method with the remaining 2 chicken breasts.

Transfer chicken to a cutting board, let rest for 5 minutes, then slice and serve.
