For the turkey

  • 6 lb bone-in, skin-on turkey breast
  • 4 tablespoons butter softened
  • 1 teaspoon garlic powder
  • 2 teaspoons onion powder
  • 2 teaspoons smoked paprika
  • 1 teaspoon dried thyme
  • 1 teaspoon salt
  • 1/2 teaspoon pepper
  • 1 large onion peeled and cut into 1 inch thick slices
  • fresh herbs for garnish optional
  • cooking spray

For the gravy

  • 4 tablespoons butter
  • 4 tablespoons flour
  • 1 cup chicken or turkey broth


  • Place the 4 tablespoons of butter, garlic powder, onion powder, smoked paprika, thyme, salt and pepper in a bowl. Stir until combined.
  • Loosen the skin of the turkey. Spread half of the butter mixture under the skin of the turkey and spread half all over the top of the turkey.
  • Coat a large oval slow cooker with cooking spray and line the bottom of the slow cooker with the onion slices.
  • Place the turkey breast on top of the onion slices. Cover and cook on low for 6 hours or until a thermometer inserted into the thickest part of the breast registers 165 degrees F.
  • Transfer the turkey breast to a baking sheet. Preheat the broiler.
  • Broil the turkey for 4-5 minutes or until skin is browned and crispy.
  • Pour the liquid from the slow cooker through a strainer; discard the solids.
  • Melt 4 tablespoons of butter in a medium pan over medium heat. Add the flour and whisk to combine.
  • Cook the flour and butter mixture for 1 minute.
  • Pour 1 cup of strained drippings and 1 cup of chicken broth in the pan.
  • Cook for 4-5 minutes or until just thickened, stirring constantly. Season to taste with salt and pepper.
  • Slice the turkey and serve with the gravy. Garnish with fresh herbs if desired.



You can make this recipe with a larger turkey breast. Simply double the amount of seasoned butter and add another hour to the cook time.
