Ingredients
- One 4-6 pound bone-in turkey breast
- 4 tablespoons unsalted butter, softened
- 2 tablespoons fresh sage, finely chopped (or 1 tablespoon dried)
- 1 tablespoon fresh thyme, finely chopped (or 1 teaspoon dried)
- 2 teaspoons fresh rosemary, finely chopped (or 1 teaspoon dried)
- 2 teaspoons kosher salt
- 1 teaspoon freshly ground black pepper
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/4 teaspoon cayenne pepper (optional, for a hint of heat)
- 1 cup low-sodium chicken broth
- 1/2 cup dry white wine or apple juice
- 1 medium yellow onion, quartered
- 4 cloves fresh garlic, smashed
- 2 medium carrots, cut into 2-inch pieces
- 2 celery stalks, cut into 2-inch pieces
- 2 bay leaves
- 1 tablespoon honey
- 2 tablespoons cornstarch (for thickening gravy, optional)
- 3 tablespoons cold water (for slurry, optional)
- Fresh herbs for garnish (optional)
Instructions
- Pat your turkey breast completely dry using paper towels. This step is crucial for better browning and seasoning adherence. Make sure to dry both the skin and the underside thoroughly.
- In a small bowl, combine the softened butter, fresh sage, thyme, rosemary, kosher salt, black pepper, garlic powder, onion powder, and cayenne pepper (if using). Mix until you have a fragrant, well-combined herb butter.
- Using your fingers or a small spatula, gently loosen the skin of the turkey breast by sliding your hand between the skin and the meat. Be gentle to avoid tearing the skin.
- Spread half of the herb butter mixture directly under the turkey skin, distributing it evenly across the meat. This creates an incredibly flavorful and moist interior.
- Rub the remaining herb butter all over the outside of the turkey breast, making sure to coat it completely. Don’t skip this step—it creates beautiful seasoning throughout.
- Place the quartered onion, smashed garlic cloves, carrot pieces, and celery pieces in the bottom of your slow cooker, arranging them to create a vegetable bed.
- Add the bay leaves to the vegetable mixture in the slow cooker base.
- Carefully place the herb-buttered turkey breast skin-side up on top of the vegetables in the slow cooker.
- Pour the chicken broth and white wine (or apple juice) around the turkey breast, being careful not to pour liquid directly over the seasoned skin. This maintains the herb coating.
- Drizzle the honey over the top of the turkey breast for a subtle sweetness that complements the savory herbs.
- Cover the slow cooker with its lid and cook on LOW for 5 to 6 hours, or on HIGH for 3 to 4 hours. The turkey is done when the thickest part of the breast reaches an internal temperature of 165°F when measured with a meat thermometer.
- Check the temperature at the 4.5-hour mark if cooking on low, or at the 2.5-hour mark if cooking on high. Every slow cooker varies in temperature, so this helps prevent overcooking.
- Once the turkey reaches 165°F internally, remove it from the slow cooker and place it on a cutting board. Tent it loosely with foil and let it rest for 10 minutes. This resting period allows the juices to redistribute throughout the meat.
- While the turkey rests, strain the cooking liquid through a fine-mesh sieve into a saucepan, discarding the vegetables and bay leaves (or save them for stock if desired).
- If you’d like to make gravy, skim any excess fat from the top of the strained cooking liquid using a spoon or fat separator.
- For thickened gravy, whisk together the cornstarch and cold water to create a slurry. Bring the cooking liquid to a simmer in the saucepan over medium heat.
- Slowly whisk the cornstarch slurry into the simmering liquid, stirring constantly until the gravy thickens to your desired consistency, about 2 to 3 minutes.
- Taste the gravy and adjust seasoning with additional salt and pepper as needed.
- Carve the rested turkey breast into thin slices against the grain for maximum tenderness.
- Arrange the carved turkey on a serving platter, drizzle with some of the gravy or cooking liquid, and garnish with fresh herbs if desired. Serve the remaining gravy on the side.
Pro Tips
Slow Cooker Size Matters: Use a 6-quart slow cooker for best results. A smaller cooker may cause the turkey to cook too quickly and unevenly, while a larger one might result in slower cooking times.
Temperature is Everything: Don’t skip using a meat thermometer. Turkey breast can dry out quickly if overcooked, so checking at 165°F internal temperature is absolutely essential for food safety and optimal moisture.
Wine Substitutions: If you don’t have white wine, apple juice, chicken broth, or even vegetable broth work beautifully. The liquid is crucial for keeping the meat moist during the long cooking process.
Herb Customizations: Feel free to swap out herbs based on your preferences. Tarragon, marjoram, or Italian seasoning all work wonderfully. Fresh herbs provide more vibrant flavor than dried, but dried herbs are perfectly acceptable.
Leftover Storage: Store cooled turkey in an airtight container in the refrigerator for up to four days. It’s perfect for sandwiches, salads, soups, or reheating gently with a bit of gravy.
Freezing Instructions: Wrap cooled turkey tightly in plastic wrap and then aluminum foil. Label with the date and freeze for up to three months. Thaw overnight in the refrigerator before reheating.
Gravy Consistency: If your gravy is too thin, let it simmer longer to reduce and concentrate the flavors. If it’s too thick, whisk in more broth a little at a time until you reach your desired consistency.
Vegetable Recycling: Don’t discard those cooked vegetables! They’re delicious as a side dish or can be pureed into a soup base.
Scaling the Recipe: This recipe can be doubled in a very large slow cooker, though you may need to add 30 minutes to the cooking time. It can also be halved using a smaller turkey breast, reducing cooking time to 4-5 hours on low.
Food Safety Reminder: Always ensure the thickest part of the turkey reaches 165°F for food safety. Never partially cook turkey ahead of time, as this creates a danger zone for bacterial growth.
