Sprinkle the chicken with your favorite chicken seasonings (mine is listed above: my go-to 'trinity' for everything I grill).
Melt the butter.
Blend in basil.
Brush the chicken breasts with basil-butter mixture.
Grill chicken breasts about 8 minutes on each side depending on how large they are (we select large sized chicken breasts) and how well-done you like your chicken (we like our moist and not dry).
Continually baste chicken with any remaining mixture while grilling to keep them ultra-moist and super flavorful.
Prepare Basil-Butter Sauce by combining all ingredients.
Serve grilled chicken breasts with the basil-butter sauce at the table for guests to top on their own.
Serve with fresh, thickly-cut Italian bread to dip into the basil-butter sauce and/or mop up what is on the plate.
