Ingredients

Scale
  • 45 lb bone-in, skin-on turkey breast
  • 4 tbsp unsalted butter, softened
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp smoked paprika
  • 1 tsp dried thyme
  • 2 tsp salt
  • 1/2 tsp black pepper
  • 1 large onion, peeled and cut into thick slices
  • Fresh thyme and rosemary sprigs (optional, for added flavor)

Gravy:

  • 4 tbsp unsalted butter
  • 4 tbsp all-purpose flour
  • 1 cup chicken broth (plus any drippings from the slow cooker)

Instructions

 

  1. Prepare the Herb Butter: In a small bowl, combine softened butter, garlic powder, onion powder, smoked paprika, thyme, salt, and pepper. Mix well to form a paste.
  2. Season the Turkey: Pat the turkey breast dry with paper towels. Gently loosen the skin with your fingers and spread half of the butter mixture under the skin and the remaining butter over the top.
  3. Arrange in Slow Cooker: Place onion slices in the bottom of the slow cooker, forming a base. Set the seasoned turkey breast on top of the onions.
  4. Cook the Turkey: Cover and cook on low for 5–6 hours, or until the internal temperature reaches 165°F (74°C). Start checking the temperature around the 5-hour mark to avoid overcooking.
  5. Broil for Crispy Skin (optional): Preheat the broiler to high. Transfer the turkey breast to a baking sheet and broil for 3–5 minutes until the skin is golden and crispy.
  6. Make the Gravy: Pour the cooking juices through a strainer into a bowl, discarding solids. In a saucepan, melt 4 tbsp butter over medium heat, then whisk in the flour. Cook for 1 minute, then slowly whisk in the turkey drippings and chicken broth. Stir until thickened, about 3–5 minutes. Season with salt and pepper to taste.
  7. Serve: Let the turkey breast rest for 10 minutes before slicing. Serve with the homemade gravy.

Notes

  • Optional Flavor Add-Ins: Add slices of lemon or sprigs of fresh rosemary for extra aroma and flavor.
