Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. In a small bowl, combine 2 tbsp olive oil, 2 tbsp chopped fresh rosemary, 1 tbsp chopped fresh thyme, 3 minced garlic cloves, 1 tsp sea salt, and 1/2 tsp ground black pepper. Rub this herb mixture evenly all over 2 lbs boneless turkey breast.
  2. Step 2: Place turkey breast on a roasting pan and roast for 50-60 minutes, or until internal temperature reaches 165°F. Remove from oven and let rest 10 minutes before slicing.
  3. Step 3: While turkey roasts, place 4 chopped carrots and 3 chopped parsnips (about 2 lbs total) in a large pot. Cover with water, add 1/2 tsp sea salt, and bring to a boil. Cook for 20 minutes until vegetables are very tender.
  4. Step 4: Drain vegetables and return to pot. Add 1 tbsp olive oil, 1/4 cup unsweetened almond milk, 1 tsp sea salt, and 1/2 tsp ground black pepper. Mash with a potato masher or hand mixer until smooth and creamy.
  5. Step 5: Slice turkey breast and serve alongside the carrot and parsnip mash.
