Why Make This Slow Cooker Herb Turkey Breast
The biggest challenge with cooking turkey is keeping it from drying out. Traditional roasting can be tricky, but the slow cooker creates a moist environment that practically guarantees juicy meat. Since the turkey simmers in its own juices and aromatics, the texture stays tender and the flavors remain concentrated.
Another reason to love this recipe is the convenience. It is a “set it and forget it” meal that allows you to go about your day. Plus, the liquid left behind in the pot makes the most incredible base for a homemade gravy that tastes like it came from a high-end restaurant.
How to Make Slow Cooker Herb Turkey Breast
Getting this turkey started takes just a few minutes of preparation before the slow cooker takes over the hard work for the rest of the afternoon.
Ingredients
- 1 (4 to 6 pound) bone-in turkey breast, thawed completely
- 1/2 cup unsalted butter, softened
- 3 cloves garlic, minced
- 1 tablespoon fresh rosemary, finely chopped
- 1 tablespoon fresh thyme, finely chopped
- 1 tablespoon fresh sage, finely chopped
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 medium yellow onion, quartered
- 2 stalks celery, cut into large chunks
- 1/2 cup chicken broth
Directions
Step 1: Prepare the Turkey
Remove the turkey breast from its packaging. Pat the skin very dry with paper towels. This helps the herb butter stick to the surface and helps the skin color better during the cooking process.
Step 2: Mix the Herb Butter
In a small bowl, combine the softened butter, minced garlic, rosemary, thyme, sage, salt, and pepper. Use a fork to mash everything together until the herbs are evenly distributed throughout the butter.
Step 3: Season the Bird
Gently loosen the skin over the turkey breast with your fingers. Rub about half of the herb butter directly onto the meat under the skin. Spread the remaining butter all over the outside of the skin, covering it as evenly as possible.
Step 4: Load the Slow Cooker
Place the onion quarters and celery chunks at the bottom of the slow cooker to act as a natural roasting rack. Pour in the chicken broth. Place the herb-rubbed turkey breast on top of the vegetables, breast-side up.
Step 5: Slow Cook
Cover the slow cooker with the lid. Cook on Low for 5 to 7 hours, or until the internal temperature reaches 165°F (74°C) when checked with a meat thermometer in the thickest part of the breast.
Step 6: Rest and Serve
Carefully remove the turkey from the slow cooker and place it on a cutting board. Tent it loosely with aluminum foil and let it rest for at least 15 to 20 minutes before carving. This allows the juices to redistribute so the meat stays moist.
How to Serve Slow Cooker Herb Turkey Breast
For a classic meal, serve thick slices of the turkey alongside creamy mashed potatoes and a generous ladle of gravy made from the cooking liquids. It also pairs beautifully with roasted root vegetables or a crisp green salad. If you want a bit of crunch, you can quickly broil the turkey in the oven for 3-5 minutes after it finishes in the slow cooker to crisp up the skin.
How to Store Slow Cooker Herb Turkey Breast
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. If you want to keep it longer, you can freeze the sliced meat in a freezer-safe bag for up to 3 months. When reheating, add a splash of broth to keep the turkey from drying out in the microwave or oven.
Expert Tips for Perfect Slow Cooker Herb Turkey Breast
Always use a meat thermometer to check for doneness. Slow cookers can vary in temperature, so checking at the 5-hour mark is a smart move. Also, try to keep the lid closed as much as possible; every time you “peek,” you lose heat and add to the total cooking time.

Delicious Variations
You can easily customize the flavor profile of this turkey. For a citrus twist, add lemon slices and orange zest to the herb butter. If you prefer a bit of heat, add a teaspoon of smoked paprika or a pinch of cayenne pepper to the rub. You can also swap the chicken broth for dry white wine to add a more sophisticated depth to the sauce.
Frequently Asked Questions
Q: Can I cook this turkey breast from frozen?
It is not recommended to cook a frozen turkey breast in a slow cooker because it stays in the “danger zone” for bacteria growth too long. Always thaw it completely in the refrigerator before starting.
Q: Do I need to add liquid to the slow cooker?
While the turkey will release its own juices, adding a small amount of chicken broth or water at the beginning helps prevent the vegetables from burning and creates a better base for gravy.
Q: How do I get crispy skin?
The slow cooker produces very tender skin but it won’t be crispy. To get that golden crunch, transfer the cooked turkey to a baking sheet and broil it in the oven for a few minutes until the skin bubbles and browns.
Q: Can I use dried herbs instead of fresh?
Yes, you can use dried herbs. Since dried herbs are more concentrated, use 1 teaspoon of dried herbs for every tablespoon of fresh herbs called for in the recipe.
Q: Will a 6-pound turkey breast fit in a standard slow cooker?
Most 6-quart or larger slow cookers will comfortably fit a 6-pound bone-in turkey breast. If your turkey is particularly tall, you may need to tent the top with foil if the lid doesn’t close perfectly, though a proper seal is always best.
