Ingredients You’ll Need

Don’t be intimidated by the list—these ingredients are simple, fresh, and each one plays a vital role in building layers of flavor while keeping the turkey moist and tender throughout the hours in the slow cooker.

• 2.5 – 3 kg / 5-6 lb single turkey breast (skin on, bone in): Choosing bone-in adds depth to the flavor and helps keep the meat juicy while cooking.
• 1/2 tsp salt: To balance and enhance the natural flavors of the turkey.
• Black pepper: Freshly ground for a gentle kick and aromatic warmth.
• 1 brown onion (halved): Adds natural sweetness and earthy undertones while slow cooking.
• 1 head of garlic (halved horizontally): Infuses the meat with bold, mellow garlic flavor.
• 3 sprigs rosemary, 8 sprigs thyme (optional): Classic herbs for a fragrant, garden-fresh aroma.
• Oil (for drizzling): Used for crisping the skin without burning the butter.
• 150 g / 10 tbsp unsalted butter (softened): The creamy base for the garlic herb butter that keeps the meat luscious.
• 1 1/2 tsp salt: For seasoning the garlic herb butter perfectly.
• 1/2 tsp black pepper: Brings mild warmth to the butter mix.
• 4 large garlic cloves (minced): Concentrated garlic punch to infuse the butter.
• 1 tbsp each finely chopped fresh sage, rosemary leaves, thyme leaves, and parsley: A medley of fresh herbs for aromatic freshness and complexity.
• Chicken broth or stock: For topping up moisture if needed during cooking.
• 1/3 cup / 50g flour: To thicken the gravy made from the reserved turkey juices.
• 1/2 tsp soy sauce or gravy coloring: Enhances the gravy’s richness and adds a beautiful deep color.

How to Make Garlic Herb Slow Cooker Turkey Breast Recipe

Step 1: Prepare the Garlic Herb Butter

Start by combining the softened butter with salt, black pepper, minced garlic, and the finely chopped fresh herbs—sage, rosemary, thyme, and parsley. This luscious butter mix will be your flavor bomb, infusing the turkey with garlicky, herbal goodness from the inside out.

Step 2: Loosen the Turkey Skin

Pat the turkey breast dry to ensure the butter adheres well. Using a small knife, carefully slide the blade between the skin and flesh to create pockets without tearing. Then, use a tablespoon to gently separate the skin from the meat all over. This step is key because it allows you to tuck most of the garlic herb butter beneath the skin, directly seasoning the turkey breast as it cooks.

Step 3: Slather on the Butter

Take about two-thirds of your garlic herb butter and spread it evenly under the loosened skin, making sure to cover the entire surface. Use the remaining butter to coat the outside of the turkey, including the underside—it’s all about layering that rich flavor everywhere!

Step 4: Season the Skin

Lightly sprinkle the turkey skin with the remaining 1/2 teaspoon of salt and some black pepper. If you have time, you can let the turkey marinate with the butter and seasoning overnight or up to 2 days refrigerated; this deepens the flavors and makes the meat even tastier.

Step 5: Arrange in the Slow Cooker

Place the halved garlic head and brown onion at the bottom of your slow cooker to create a flavorful base. Set the turkey breast, skin side up, right on top of the onions and garlic. Tuck in the sprigs of rosemary and thyme around the turkey for extra herbal aroma as it cooks.

Step 6: Slow Cook the Turkey

Cover and cook on low for about 6 hours. It’s good to check around 4 hours to ensure everything is moist and to prevent overcooking, but the turkey is done when it reaches an internal temperature of 75°C (165°F). Slow cooking means your turkey will stay tender and juicy, soaking in all the garlic and herb flavors.

Step 7: Let It Rest

Once cooked, transfer the turkey to a baking tray, reserving the cooking juices for gravy. Cover the turkey loosely with foil and let it rest for 20 minutes, allowing the juices to redistribute for ultimate moistness.

Step 8: Crisp the Skin

To get that irresistible crispy and bronzed skin, drizzle the turkey with a little oil (avoid butter here as it can burn). Place the tray under a broiler or grill on high heat about 30 cm (12 inches) from the heat source for 5 to 10 minutes. Keep a close eye so it crisps perfectly without burning.

Step 9: Prepare the Gravy

Use the reserved juices to make a luscious gravy by whisking in flour and a splash of soy sauce or gravy coloring for richness and depth. Simmer until thickened and smooth, ready to drizzle over your turkey.

How to Serve Garlic Herb Slow Cooker Turkey Breast Recipe

Garnishes

Fresh herbs such as sprigs of rosemary or thyme look stunning when scattered over sliced turkey. A generous dollop of cranberry sauce adds a beautiful color contrast along with a burst of sweet tartness that complements the savory herbs perfectly.

Side Dishes

This recipe pairs wonderfully with creamy mashed potatoes, roasted root vegetables, or a simple green salad with a zesty vinaigrette. For a comforting feast, try buttery dinner rolls and seasonal steamed greens, which balance the rich flavors of the turkey beautifully.

Creative Ways to Present

Serve sliced turkey breast on a rustic wooden platter with fresh herb sprigs and small bowls of gravy and cranberry sauce alongside for an inviting family-style presentation. Or get fancy by layering turkey slices over thick toasted bread for herbaceous turkey sandwiches with a garlic aioli spread.

Make Ahead and Storage

Storing Leftovers

Once cooled, store leftover turkey breast tightly wrapped in airtight containers in the fridge. It will keep well for up to 3 days, making it perfect for delicious next-day sandwiches or quick reheated meals.

Freezing

If you want to save some for later, sliced turkey breast freezes beautifully. Wrap portions in plastic wrap and foil or vacuum seal before freezing. It will keep its quality up to 3 months and is easy to thaw in the fridge overnight.

Reheating

Reheat slices gently in a low oven wrapped in foil or warm them in a covered skillet with a splash of broth to prevent drying out. To revive crisp skin, finish under a hot broiler for a few minutes just before serving.

FAQs

Can I use a boneless turkey breast for this recipe?

Yes, you can substitute with boneless turkey breast, but keep in mind the bone adds flavor and helps retain moisture. Adjust cooking time slightly as boneless pieces may cook faster.

Do I have to use fresh herbs in the garlic butter?

Fresh herbs are best for bright, vibrant flavor, but if you only have dried herbs, you can use about one-third of the quantity. Just be sure to crush them to release their oils before mixing.

What if I don’t have a slow cooker?

You can adapt this recipe for the oven by roasting the turkey at 160°C (320°F) for approximately 2 to 2.5 hours, covering loosely with foil and following the crisping skin step at the end.

Is it okay to cook the turkey breast overnight?

Absolutely! Slow cooking overnight on the low setting is convenient and safe, making your turkey perfectly tender by morning. Just check it early to avoid overcooking if your slow cooker runs hot.

How do I know when the turkey is done?

Use a meat thermometer inserted into the thickest part of the breast. When it reads 75°C (165°F), the turkey is safely cooked through and ready to rest before serving.
