Place one 12–14-lb. turkey, neck reserved for gravy and giblets discarded, on a wire rack set inside a rimmed baking sheet and pat dry with paper towels. Sprinkle Bone Suckin' Seasoning all over outside of the turkey as well as inside the cavity of the turkey.

Place turkey, breast side up, on rack and tuck wings underneath. Place an oven rack in middle of oven; preheat oven to 450°. Using your fingers, loosen turkey skin on breast. Work 4 Tbsp. butter, room temperature, under skin, spreading evenly over both breasts. Smear outside of turkey with another 4 Tbsp. butter, room temperature. Add water to pan.

Roast turkey, rotating pan halfway through, until skin is mostly golden brown all over, about 30 minutes. Reduce oven temperature to 300°F and continue to roast turkey, basting with liquid in pan every 30 minutes and until an instant-read thermometer inserted into the thickest part of breast near the neck registers 170°F. Skin should be deep golden brown, shiny, and crisp. Transfer turkey to a cutting board and let rest at least 30 minutes and up to 1 hour before carving.
