2 bone-in, skin-on turkey breast halves (5 to 6 pounds total)
½ cup unsalted butter, softened
1½ tablespoons kosher salt
2 teaspoons ground black pepper
Sauce:
3 tablespoons all-purpose flour
1 cup low-sodium chicken broth
¾ cup dry white wine
1 tablespoon Dijon mustard
Instructions
Preheat oven to 450°.
For turkey: Place garlic, rosemary, sage, and thyme in a 12-inch cast-iron skillet. Place turkey breasts, skin side up, on top of garlic and herbs. Pat turkey dry with a paper towel. Rub butter over outside of turkey breasts. Sprinkle with salt and pepper.
Bake until turkey is golden brown and a meat thermometer registers 165°, about 1 hour and 10 minutes. Transfer turkey to a platter.
For sauce: Place skillet with drippings over medium heat. Sprinkle with flour; cook for 1 minute, stirring frequently. Whisk in broth, wine, and mustard, scraping browned bits from bottom of skillet. Cook until slightly thickened, about 3 minutes. Strain, if desired, and serve with sliced turkey.
