Remove bone from turkey breast, leaving skin and meat intact.
Place turkey between 2 sheets of heavy-duty plastic wrap, and flatten to 1-inch thickness using a meat mallet or rolling pin. Rub skinless side of turkey breast with rosemary and garlic; spread with rice mixture. Starting at a long side, tightly roll up breast, jellyroll fashion; secure at 2-inch intervals with kitchen string. Sprinkle with salt and 1 tablespoon pepper; place on a lightly greased rack in a roasting pan.
Bake at 375° for 2 hours or until a meat thermometer inserted into thickest portion registers 180°. Remove from pan, reserving drippings; let stand 10 minutes.
Melt butter in a heavy saucepan over low heat; stir in reserved drippings. Whisk in flour until smooth. Cook, whisking constantly, 1 minute. Gradually add reserved wine and remaining 1 1/2 cups broth; cook over medium heat, whisking often, 5 minutes or until thickened. Serve with turkey.
