Garlic cloves: Whole cloves simmer to a mellow, aromatic flavor without any sharpness.
Carrots: Diced into 2-inch pieces, they add a bit of subtle sweetness and body to the cooking liquid.
Chicken broth: Locks in moisture and adds flavor depth without extra salt.
Fresh rosemary and sage: Sprigs infuse the turkey with an earthy herbal fragrance while it slow cooks.
Softened butter: The base of the herb rub, distributing flavor and helping the dried herbs stick.
Garlic powder, dried onion flakes, salt, paprika, dried sage, rosemary, thyme, black pepper: These spices combine to make a deeply savory and fragrant butter rub that penetrates the turkey.

Variations

I love tweaking this Slow Cooker Herb Turkey Breast Recipe depending on the season and what herbs I have fresh in the garden. Feel free to make it your own by swapping herbs or boosting the flavor with extras you enjoy.

Using fresh herbs only: I once swapped all the dried herbs for fresh thyme and oregano, which gave the turkey a brighter, more vibrant flavor—definitely worth trying.
Adding citrus zest: Adding lemon or orange zest to the butter mix adds a lovely zing that complements the savory herbs beautifully.
Spicier twist: A sprinkle of smoked paprika and a dash of cayenne can give this recipe a smoky heat that my family adored!
Gluten-free modification: This recipe is naturally gluten-free, but double-check your chicken broth brand just to be safe.

How to Make Slow Cooker Herb Turkey Breast Recipe

Step 1: Prep Your Slow Cooker and Veggies

Start by lining your slow cooker with a liner or giving it a good spray with non-stick cooking spray—this helps with cleanup later, which is always a win. Then place the peeled and quartered onion, whole garlic cloves, diced carrots, chicken broth, and the fresh rosemary and sage sprigs directly into the bottom of the slow cooker. This creates a flavorful bed that steams the turkey perfectly.

Step 2: Make the Herb Butter Rub

In a bowl, mix your softened butter with garlic powder, dried onion flakes, salt, paprika, and all the dried herbs—sage, rosemary, and thyme—plus black pepper. Stir until it’s evenly combined and smelling fabulous. This butter rub is the real hero of the recipe, giving that rich, herby flavor throughout the turkey breast.

Step 3: Coat the Turkey and Start Cooking

Generously spread the herb butter all over your turkey breast roast, making sure to cover every inch. Then carefully place the turkey on top of the veggies and broth in your slow cooker. Set it to LOW for 6 hours or HIGH for about 4 hours—whichever suits your schedule. The turkey is done when it reaches 165°F inside; using a meat thermometer is a game-changer here and ensures safe, perfectly cooked meat every time.

Step 4: Rest and Slice

Once the turkey’s cooked, lift it out carefully and let it rest for about 5 minutes. This step is key to locking in juices. Then slice against the grain and serve. You’ll be amazed at how juicy and flavorful this turkey tastes, and all with minimal effort!

Pro Tips for Making Slow Cooker Herb Turkey Breast Recipe

Prep Ahead: Soften the butter and mix the herb rub the night before for super quick assembly.
Use a Meat Thermometer: This ensures your turkey hits that perfect 165°F without drying out—my slow cooker was never the same after I started using one.
Don’t Skip Resting: Letting your turkey rest for a few minutes makes slicing easier and keeps the meat juicy.
Carrot Chop Size: Cutting carrots into larger chunks prevents them from getting mushy and keeps texture in the veggie bed.

Garnishes

I personally love garnishing the sliced turkey breast with a few fresh rosemary sprigs or a sprinkle of freshly chopped parsley to brighten the plate. A little lemon wedge on the side adds a nice zing when squeezed over the meat just before eating.

Side Dishes

My go-to sides here are creamy mashed potatoes or roasted garlic cauliflower mash, plus steamed green beans tossed with a bit of butter and toasted almonds. Sometimes I throw together a simple wild rice pilaf, and that combo never disappoints. You’ll find the turkey pairs beautifully with earthy and buttery flavors.

Creative Ways to Present

For special occasions, I’ve layered slices of the herb turkey over a bed of fresh arugula with dried cranberries and toasted pecans, drizzled with balsamic glaze. It looks gorgeous and tastes like a restaurant dish—impressive but so easy to put together!

Make Ahead and Storage

Storing Leftovers

I let leftovers cool completely, then store slices in an airtight container in the fridge. The turkey keeps well for 3-4 days, making it perfect for quick lunches or easy dinners throughout the week.

Freezing

If you want to freeze the turkey, I wrap slices tightly in plastic wrap, then place them in a freezer-safe bag. It freezes beautifully and stays moist after thawing, so you can batch-cook and save time on busy days.

Reheating

To reheat, I prefer warming slices gently in the microwave with a damp paper towel on top to keep moisture in, or popping them in a covered dish in a 325°F oven until warmed through. This helps maintain that tender, juicy texture you love.

FAQs

Can I use bone-in turkey breast instead of boneless?

You absolutely can! Just note that bone-in pieces might take a little longer to cook, so add extra time and always check the internal temperature to make sure it reaches 165°F.
Is it okay to cook this Slow Cooker Herb Turkey Breast Recipe on high instead of low?

Yes! You can cook it on high for about 4 hours instead of 6 hours on low. Just keep an eye on it towards the end and check the internal temperature often to avoid overcooking.
Can I add other vegetables to the slow cooker?

Definitely! Feel free to add celery, parsnips, or even small potatoes—they’ll cook alongside the turkey and soak up some wonderful flavors.
How do I make sure the turkey stays moist?

The key is not skipping the broth and the veggies that steam while cooking, plus that herb butter rub. Also, resting the turkey before slicing helps the juices redistribute so every bite stays juicy.
Can I prepare this recipe ahead and refrigerate before cooking?

You sure can. Apply the herb butter rub to the turkey and cover it tightly in the fridge up to 24 hours before cooking. This even helps deepen the flavor.
