Preparation instructions
Prepare the Marinade
1In a bowl, combine the olive oil, minced garlic, chopped rosemary, thyme leaves, lemon zest and lemon juice, salt, and freshly ground black pepper. Mix well to create a fragrant marinade.
Marinate the Turkey
2Place the turkey breast in a large zip-top bag or a shallow dish. Pour the marinade over the turkey, making sure it is evenly coated. Seal the bag or cover the dish and refrigerate for at least 4 hours, ideally overnight, to allow flavors to penetrate.
Prepare the Slow Cooker
3Remove the turkey from the refrigerator and allow it to come to room temperature for about 20 minutes. Transfer the turkey along with the marinade into the slow cooker. Ensure the turkey breast is skin-side up for optimum tenderness and moisture retention.
Slow Cook the Turkey
4Cover and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours. The exact time depends on your slow cooker model and size of turkey breast. Use a meat thermometer to check the internal temperature.
Check for Safe Internal Temperature
5Insert an instant-read meat thermometer into the thickest part of the turkey breast. The turkey is safely cooked when the internal temperature reaches 74°C (165°F). If it hasn’t reached this temperature, continue cooking and check every 30 minutes.
Rest the Turkey Breast
6Once cooked to safe temperature, remove the turkey breast from the slow cooker and place it on a cutting board. Tent with foil and let it rest for 10 to 15 minutes to allow the juices to redistribute, ensuring juicy slices.
Slice and Serve
7Slice the turkey breast against the grain into desired thickness. Serve with your favorite sides, and enjoy tender, flavorful turkey.
Cooking Tips
1Use an instant-read meat thermometer to precisely check the internal temperature and avoid under or overcooking.
2Marinating overnight yields deeper flavor and more tender meat, but 4 hours is the minimum to taste good.
3For a gluten-free version, double-check that your salt and spices are pure and free from additives.
4If you prefer skinless turkey breast, remove skin before marinating; cooking time remains similar.
5Use tongs and clean hands when handling raw turkey to avoid cross-contamination; always wash surfaces and utensils afterward.
