Ingredients You’ll Need
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Turkey
3 lb boneless turkey breast – If it comes trussed with string, leave it as-is so it stays together.
Butter & Aromatics
4 tablespoons butter, softened – Helps the seasoning adhere and keeps the meat moist.
1 large yellow onion, cut into ½-inch slices – Acts as a flavorful bed for the turkey.
Seasonings
2 teaspoons kosher salt
½ teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon dried oregano or 1 tablespoon fresh
1 teaspoon dried thyme or 1 tablespoon fresh
1 teaspoon paprika
½ teaspoon turmeric (optional)
For Garnish
Fresh herbs such as parsley, thyme, or rosemary (optional)
Let’s Get Started
1. Prepare the Turkey Breast
Pat the turkey breast dry with paper towels. This helps the butter rub stick and improves the overall flavor.
2. Make the Herb Butter
In a small bowl, mix together the softened butter, salt, pepper, garlic powder, oregano, thyme, paprika, and turmeric until it forms a smooth, well-blended paste.
3. Season Generously
Rub the butter mixture all over the turkey breast—on all sides and underneath any loose areas of the skin (if applicable). This is key for flavor and keeping the breast moist as it cooks.
4. Build the Base in the Slow Cooker
Place the sliced onions in the bottom of the slow cooker. This acts like a roasting rack and infuses the turkey with savory aroma as it cooks.
5. Add the Turkey
Set the seasoned turkey breast on top of the onions. If it’s trussed with string, keep it tied for even cooking.
6. Slow Cook to Juicy Perfection
Cover and cook:
- On LOW for 5–6 hours
- Or on HIGH for 3–4 hours
The turkey is done when it reaches 165°F in the thickest part.
7. Rest Before Slicing
Remove the turkey from the slow cooker and let it rest for 10–15 minutes. This helps the juices redistribute for clean, tender slices.
8. Garnish and Serve
Top with fresh herbs and serve warm alongside your favorite sides.
Servings and Pairing
This recipe serves 6–8 people, depending on appetite and portion size.
Perfect Pairings
- Mashed potatoes or garlic herb roasted potatoes
- Steamed green beans or roasted vegetables
- Cranberry sauce
- Stuffing or rice pilaf
- Homemade gravy made from the slow cooker drippings
You can also slice the turkey for sandwiches, wraps, salads, or grain bowls.
Variations
- Citrus Herb Turkey: Add sliced lemon or orange under the turkey.
- Garlic Lover’s Version: Add 5–6 whole garlic cloves with the onions.
- Spicy Turkey: Add ½ teaspoon cayenne or crushed red pepper flakes.
- Butter-Free Option: Replace butter with olive oil if needed.
- Herb-Heavy Version: Use extra fresh thyme, rosemary, and sage for a holiday flavor profile.
Storage Tips
- Refrigerator: Store sliced or shredded turkey in an airtight container for up to 4 days.
- Freezer: Freeze in meal-size portions for up to 3 months. Add some cooking juices to keep it moist.
- Reheating: Warm gently in the oven or microwave. For best results, drizzle a little broth over the turkey before reheating to keep it tender.
FAQs
How do I know when the turkey is done?
Use a meat thermometer. It’s fully cooked at 165°F in the thickest part.
Can I use bone-in turkey breast instead?
Yes! It may take slightly longer, especially on low. Add 30–60 extra minutes of cook time.
Can I cook vegetables with the turkey?
Absolutely—carrots and celery work well and create a delicious base for gravy.
What if my turkey breast is frozen?
Thaw it completely in the refrigerator before slow cooking to ensure even cooking.
Can I brown the turkey after slow cooking?
Yes! Broil it for 3–5 minutes for a golden, crisp exterior.
