Ingredients

Servings 6
  • 1 (3 to 4 lb) boneless skin-on turkey breast
  • 2 tablespoons olive oil
  • 1 tablespoon lemon zest (from about 1 lemon)
  • 3 tablespoons fresh lemon juice
  • 4 cloves garlic, minced
  • 2 teaspoons fresh thyme leaves (or 1 teaspoon dried thyme)
  • 1 teaspoon fresh rosemary, chopped (or 1/2 teaspoon dried rosemary)
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 pound carrots, peeled and cut into 2-inch pieces
  • 1 pound parsnips, peeled and cut into 2-inch pieces
  • 1 pound baby potatoes, halved if large
  • 1 large onion, quartered
  • 1 cup low-sodium chicken broth
  • 1 tablespoon unsalted butter (optional, for finishing)
  • Fresh parsley, chopped (for garnish)

Instructions

  1. 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.
  2. Rub the marinade evenly all over the turkey breast, ensuring to get under the skin for maximum flavor infusion.
  3. Arrange the carrots, parsnips, baby potatoes, and onion evenly in the bottom of the slow cooker.
  4. Place the marinated turkey breast on top of the vegetables, skin side up.
  5. Pour the chicken broth around the vegetables (avoid pouring directly on the turkey) to maintain moisture during cooking.
  6. 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).
  7. About 30 minutes before cooking completes, carefully transfer the turkey and vegetables to a sheet pan or oven-safe baking dish.
  8. Preheat the oven to 425°F (220°C) while leaving the slow cooker on warm.
  9. 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.
  10. Remove from oven; if desired, dab the turkey with butter and let rest for 10 minutes before slicing.
  11. Garnish turkey and vegetables with chopped fresh parsley before serving.
  12. Serve warm, spooning pan juices over the turkey and vegetables for extra flavor.
  13. To freeze leftovers, allow to cool completely, then portion into airtight containers and freeze for up to 3 months.

Frequently Asked Questions

Customize this Slow Cooker Lemon Herb Turkey Breast with Roasted Root Vegetables to suit dietary preferences or ingredient availability with these simple substitutions:

  • Turkey Breast: Swap for boneless chicken breasts or thighs for a faster, budget-savvy option. Firm white fish fillets can serve pescatarian diets, adjusting cooking time accordingly.
  • Olive Oil: Use avocado oil or melted coconut oil as flavorful alternatives.
  • Lemon Zest and Juice: Substitute with lime zest and juice for a different citrus twist.
  • Fresh Herbs (Thyme, Rosemary): Use one-third the amount of dried herbs if fresh aren’t available, or use an Italian herb blend.
  • Root Vegetables: Replace carrots, parsnips, and potatoes with sweet potatoes, turnips, or butternut squash for variety or lower-carb options.
  • Low-Sodium Chicken Broth: Use vegetable broth for vegetarian or dairy-free adaptations.
  • Butter: Swap with additional olive oil or plant-based margarine to keep the dish dairy-free.

These substitutions preserve the recipe’s nutritious, easy-to-make, and family-friendly nature while offering flexibility to your pantry and preferences.

Pan Or Pot Required

This recipe falls under Slow Cooker One-Pot meals, requiring a slow cooker to perfectly tenderize the turkey breast and root vegetables with minimal hands-on effort. Slow cooking gently infuses flavors and creates a juicy, melt-in-your-mouth texture.

For a crispy skin and beautifully caramelized vegetables, finish the cooking in the oven using a sheet pan or oven-safe baking dish. This step adds a golden crust and depth of flavor not possible in the slow cooker alone.

Essential Cookware:

  • Slow Cooker: For low and slow cooking that melds flavors while keeping ingredients moist.
  • Sheet Pan or Oven-Safe Dish: To crisp turkey skin and roast vegetables to a perfect caramelization.

This combination ensures a convenient, family-friendly, and budget-conscious cooking approach with easy cleanup — ideal for busy weeknights or meal prepping in advance.

Cookware Size Guidance

Use a 6 to 7-quart slow cooker to comfortably fit a 3 to 4 lb turkey breast along with approximately 3 pounds of mixed root vegetables. This size provides ample space for even heat circulation and prevents overcrowding, ensuring moist, evenly cooked results.

When roasting, opt for a rimmed baking sheet or shallow roasting pan approximately 9x13 inches or larger. This allows vegetables and turkey skin to caramelize evenly without steaming.

Choosing the right size slow cooker is important: too small causes crowding and uneven cooking; too large may dry out ingredients due to excess air circulation.

Cookware Swap Guidance

If you don’t have a slow cooker, you can still enjoy this recipe with alternate equipment that maintains convenience and flavor:

  • Instant Pot or Electric Pressure Cooker: Use sauté mode to brown the turkey breast, then pressure cook with broth and vegetables. Finish by crisping skin under the broiler or in a hot skillet.
  • Oven-Safe Dutch Oven or Heavy Casserole: Brown turkey on stovetop, then add vegetables and broth and cover. Slow roast at 275°F (135°C) for 3-4 hours. Finish uncovered to crisp skin and caramelize vegetables.
  • Covered Sheet Pan Roasting: Arrange marinated turkey and vegetables on a sheet pan covered with foil or a lid. Roast gently, then uncover near the end to achieve crisp skin and caramelized vegetables.

Regardless of method, slow and low cooking maintains turkey tenderness and vegetable softness. Finishing with a high-heat roast enhances skin crispness and flavor depth. These alternatives maintain the recipe’s ease, family-friendly qualities, and comforting appeal.

Leftovers Quality

Leftovers from this Slow Cooker Lemon Herb Turkey Breast with Roasted Root Vegetables keep well refrigerated in airtight containers for 3 to 4 days, making this recipe ideal for easy meal prep and quick family dinners throughout the week.

Allow leftovers to cool completely before refrigerating. To reheat, gently warm in a 325°F (165°C) oven covered loosely with foil for 20-25 minutes to preserve moist turkey and tender vegetables. Microwaving is an option but may lead to dryness.

For long-term storage, freeze in airtight freezer-safe containers or heavy-duty bags for up to 3 months. Thaw overnight in the refrigerator and reheat as directed.

This recipe’s blend of juicy turkey and caramelized vegetables retains its delicious flavor and texture well, making it a dependable, time-saving, and budget-friendly meal solution.
