👩‍🍳 Instructions – Step by Step

1. Prepare the Turkey Breast

Remove the fully thawed turkey breast from its packaging.

Check for any netting, plastic, or packaging materials and remove them if appropriate for the product.

Place the turkey breast on a clean cutting board and gently pat the entire surface dry using paper towels.

Removing excess surface moisture helps the herb butter adhere evenly to the turkey.

Transfer the turkey breast directly into a 6-quart slow cooker, positioning it with the rounded surface facing upward.

Keep the thicker portion positioned toward the center of the slow cooker for more even cooking.

2. Prepare the Garlic Butter

Place ½ cup (113 g) softened unsalted butter into a small mixing bowl.

Allow the butter to soften at room temperature until it becomes smooth and easy to spread.

Add the three crushed garlic cloves.

Using a small spoon or spatula, mix the butter and garlic together until the garlic is completely incorporated into a smooth, fragrant paste.

Make sure there are no large pieces of garlic remaining.

3. Apply the Butter and Garlic

Spoon the softened garlic butter directly onto the upper surface of the turkey breast.

Using clean hands or a silicone spatula, gently spread the mixture over the entire rounded surface and visible sides.

Work the butter into an even layer, making sure the turkey is generously coated.

Pay particular attention to the thicker areas so they receive plenty of garlic butter.

Wash your hands thoroughly after handling the raw turkey.

4. Add the Fresh Rosemary

Sprinkle 1 tablespoon of finely chopped fresh rosemary evenly over the butter-coated turkey breast.

Distribute the rosemary across the entire upper surface.

Its aromatic, slightly pine-like flavor gives the turkey a delicious traditional herb-roasted taste.

5. Add the Fresh Thyme

Sprinkle 1 tablespoon of fresh thyme leaves over the turkey.

Spread the leaves evenly so they become incorporated into the garlic butter.

Thyme adds a subtle earthy flavor that pairs beautifully with poultry and butter.

6. Add the Fresh Parsley

Sprinkle 1 tablespoon of finely chopped fresh parsley over the turkey breast.

Distribute it gently across the surface.

Parsley adds freshness and balances the richness of the butter.

7. Season the Turkey

Add the seasonings individually and evenly.

First, sprinkle 1 teaspoon of salt over the turkey, reducing the amount if the turkey has already been brined.

Next, add ½ teaspoon freshly ground black pepper.

Finally, sprinkle ½ teaspoon paprika over the herb butter coating.

The paprika adds beautiful color and a mild, warm flavor.

8. Slow Cook the Turkey

Place the lid securely on the slow cooker.

Cook on LOW for approximately 4–6 hours, depending on the thickness of the turkey breast and your slow cooker.

Begin checking the internal temperature around the 3-hour mark.

During cooking:

  • The butter gradually melts into the turkey.
  • The garlic releases its savory aroma.
  • Rosemary and thyme infuse the cooking juices.
  • The turkey absorbs the flavors of the herbs and seasonings.
  • The buttery juices collect around the bottom of the slow cooker.

Keep the lid closed as much as possible to maintain a consistent cooking temperature.

Important: Cooking time is only an estimate. Insert a food thermometer into the thickest part of the turkey breast, avoiding the bottom of the slow cooker. The turkey must reach an internal temperature of 165°F (74°C) before serving.

Remove it once it reaches the required temperature to help prevent overcooking and dryness.

9. Check the Cooking Juices

Once the turkey is fully cooked, carefully remove the lid.

You should see melted garlic butter, fragrant herbs, and delicious turkey juices collected at the bottom.

The turkey should be tender and moist, with the herb butter coating softened beautifully.

Using a spoon, gently stir the buttery cooking juices to combine the melted butter, garlic, herbs, and natural turkey juices.

Taste the liquid and adjust the seasoning if necessary.

10. Transfer and Rest the Turkey

Carefully lift the turkey breast out of the slow cooker using large serving forks or sturdy tongs.

Transfer it to a warm serving platter.

Keep the softened herb coating intact as much as possible.

Allow the turkey to rest for approximately 10–15 minutes before slicing.

Resting helps the juices redistribute throughout the meat, making every slice more tender and moist.

11. Slice the Turkey Breast

Place the rested turkey breast on a clean cutting board.

Using a sharp carving knife, slice the turkey across the grain into even slices, approximately ½-inch thick.

Avoid pressing too hard while slicing because the meat should remain tender and juicy.

Arrange the slices neatly on a large white serving platter, slightly overlapping them for an attractive presentation.

12. Spoon Over the Garlic Herb Butter

Take the warm buttery cooking juices from the slow cooker.

Spoon a generous amount directly over the turkey slices.

Make sure the liquid reaches the exposed cut surfaces as well as the spaces between the slices.

This adds moisture, flavor, and a beautiful glossy finish.

13. Garnish and Serve

Finish with freshly chopped parsley, a few rosemary sprigs, and fresh thyme leaves.

Add a little freshly cracked black pepper if desired.

Serve immediately while warm, with plenty of garlic herb butter juices spooned over each portion.

💡 Expert Tips for the Best Results

  • Use fully thawed turkey: Never place a frozen turkey breast directly into the slow cooker.
  • Choose softened butter: Soft butter spreads more evenly and helps the herbs stick.
  • Use fresh herbs: Fresh rosemary, thyme, and parsley provide a wonderful aromatic flavor.
  • Create a smooth garlic paste: This helps distribute garlic flavor evenly without large raw garlic pieces.
  • Reduce the salt if brined: Some commercially prepared turkey breasts already contain added salt.
  • Don’t add unnecessary liquid: The butter and natural turkey juices create a flavorful cooking liquid.
  • Keep the lid closed: Frequent opening can increase cooking time.
  • Use a thermometer: Always check the thickest part and cook to 165°F (74°C).
  • Avoid overcooking: Remove the turkey as soon as it reaches the safe internal temperature.
  • Rest before slicing: Allowing the turkey to rest helps retain its natural juices.
  • Slice across the grain: This produces more tender, easier-to-eat slices.
  • Spoon over the juices: Don’t waste the garlic herb butter collected at the bottom of the slow cooker!

❓ Frequently Asked Questions

Can I use bone-in turkey breast?

Yes, but cooking time may differ depending on the size and shape. Always check the thickest part with a food thermometer.

Can I use salted butter?

Yes. However, reduce or omit the additional salt, especially if the turkey is already brined.

Do I need to add chicken broth or water?

No. The butter and natural turkey juices provide moisture for this recipe.

Can I cook this on HIGH?

LOW is recommended for more gentle, even cooking. If using HIGH, monitor the internal temperature closely because cooking time can vary considerably.

Why is my turkey breast slightly pale?

Slow cookers create a moist cooking environment, so the turkey generally won’t develop the browned exterior of an oven-roasted turkey. For a more golden finish, you can briefly place the fully cooked turkey under the oven broiler, watching carefully.

Can I make the turkey ahead of time?

Yes! Cook the turkey, slice it, and refrigerate it with some of the garlic herb butter juices. Reheat gently with the juices to help keep it moist.

Can I use dried herbs instead of fresh?

Yes. Dried herbs are more concentrated, so use approximately 1 teaspoon dried rosemary, 1 teaspoon dried thyme, and 1 teaspoon dried parsley instead of the fresh quantities.

Tender, juicy slices of boneless turkey breast coated in rich garlic butter, fragrant rosemary, fresh thyme, and parsley.
