Ingredients for Slow Cooker Lemon Herb Turkey Breast with Roasted Root Vegetables

Instructions

In a small bowl, whisk together olive oil, lemon zest, lemon juice, minced garlic, thyme, rosemary, salt, and black pepper to create the lemon herb marinade.
Rub the marinade evenly all over the turkey breast, ensuring to get under the skin for maximum flavor infusion.
Arrange the carrots, parsnips, baby potatoes, and onion evenly in the bottom of the slow cooker.
Place the marinated turkey breast on top of the vegetables, skin side up.
Pour the chicken broth around the vegetables (avoid pouring directly on the turkey) to maintain moisture during cooking.
Cover and cook on low for 6 to 7 hours, or until a meat thermometer inserted into the thickest part of the turkey reads 165°F (74°C).
About 30 minutes before cooking completes, carefully transfer the turkey and vegetables to a sheet pan or oven-safe baking dish.
Preheat the oven to 425°F (220°C) while leaving the slow cooker on warm.
Roast the turkey skin side up and vegetables for 20-25 minutes, or until the turkey skin is golden brown and crispy and the vegetables are caramelized to your preference.
Remove from oven; if desired, dab the turkey with butter and let rest for 10 minutes before slicing.
Garnish turkey and vegetables with chopped fresh parsley before serving.
Serve warm, spooning pan juices over the turkey and vegetables for extra flavor.
To freeze leftovers, allow to cool completely, then portion into airtight containers and freeze for up to 3 months.
