Step 1: Prepare the Herb Butter Mixture
Create an aromatic compound by combining softened butter, minced garlic, fresh herbs, lemon zest, salt, pepper, and paprika in a small bowl. This fragrant mixture will penetrate the turkey skin, creating layers of flavor that develop throughout the slow cooking process.
Step 2: Season and Prep the Turkey
Pat the turkey breast completely dry using paper towels – this crucial step ensures better seasoning adherence and prevents excess moisture. Gently loosen the skin and spread half the herb butter mixture directly onto the meat, then smooth the skin back down. Rub the remaining mixture over the entire surface.
Step 3: Sear for Enhanced Flavor
Heat olive oil in a large skillet over medium-high heat. Sear the turkey breast skin-side down for 3-4 minutes until golden brown. This optional step adds nearly some of more flavor complexity through the Maillard reaction, creating deeper taste notes.
Step 4: Layer the Slow Cooker Base
Arrange onion slices in the bottom of your slow cooker, creating a natural rack that prevents sticking while adding sweetness to the cooking liquid. Pour chicken broth around the edges, being careful not to wash off the herb seasoning.
Step 5: Slow Cook to Perfection
Place the seasoned turkey breast skin-side up in the slow cooker. Cover and cook on low for 4-6 hours, or until the internal temperature reaches 165°F in the thickest part. Avoid lifting the lid unnecessarily, as this releases heat and extends cooking time.
Step 6: Rest and Finish
Remove the turkey and let it rest for 10 minutes before carving. This resting period allows juices to redistribute, ensuring each slice remains succulent and flavorful.
