Herb-Garlic Butter Spatchcocked Chicken

Heat oven to 375°F. Line 15 x 10 x 1-inch pan with foil.

Pat chicken dry with paper towels. Place chicken, breast side down, on cutting board. Using heavy-duty kitchen scissors or poultry shears, cut closely along one side of backbone from thigh end to neck. Repeat on other side. Remove backbone; save for making Chicken and Broth or Roasted Chicken and Broth or discard. Turn chicken over; flatten breast area by pressing firmly with heel of hand. Place chicken, breast side up, in pan. Tuck wings under breast.

In small bowl, beat remaining ingredients with electric mixer on medium speed until light and fluffy. Starting at leg end of chicken, gently separate skin (do not peel back) from chicken breast using fingers, being careful not to tear or puncture skin. Rub half of butter mixture under skin to cover entire breast area; gently replace skin. Rub remaining butter mixture on outside of chicken.

Roast uncovered 30 minutes. Brush chicken with pan juices. Roast 30 to 35 minutes longer or until thermometer inserted in thickest part of breast reads at least 165°F. Serve chicken with pan juices, if desired.
