Heat 1-1/2 tablespoons vegetable oil over medium-high heat in a large skillet; use a 10-inch or 12-inch skillet.
Pat dry the chicken breasts with paper towels.
Drizzle just 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.
Cook chicken breasts for 5 to 7 minutes without moving them around.
Flip both chicken breasts over, add 1 tablespoon of butter to the skillet; swirl butter around and continue to cook the chicken for 7 more minutes, or until internal temperature reaches 165F. Cooking time will always depend on the thickness of the chicken breasts.
Remove chicken breasts from skillet; set aside and keep covered.
Repeat the same method with the remaining 2 chicken breasts.
When finished, transfer chicken to a cutting board; let rest for 5 minutes, then slice and serve.
