Place the chicken breasts in a 9x13 pan and pour the olive oil over them. With your hands or tongs, dredge the chicken breasts in the oil coating all sides.
Sprinkle half of the spice rub over one side of the chicken breasts then flip them over and sprinkle the other side with the remaining spices. Place one piece (1 Tablespoon) of butter on top of each chicken breast.
4 Tablespoons butter, cut into 4 pieces
Bake uncovered for 20-25 minutes or until the breasts reach 165F (see notes). Once the chicken breasts are removed from the oven, allow them to rest for 10 minutes before serving to allow the juices to redistribute.
Slice and serve with a generous drizzle of the pan drippings (they add so much flavor!). Store leftovers in the fridge in an airtight container for up to 5 days.

Notes
Baking Tips - We have found that 450F is the best temperature to bake chicken breasts. Use a digital read thermometer to check for doneness to prevent undercooking or overcooking. Resting is a very important step! It allows the chicken to redistribute the juices so the chicken stays tender. Larger chicken breasts or chicken more chilled from the fridge, may take closer to 25 minutes. For smaller chicken breasts, check for doneness after 15 minutes.Storage Tips - Freeze chicken breasts with pan drippings in an airtight container for up to 3 months.Calories are calculated for 2 pounds of uncooked chicken serving six people once cooked.
