Turkey Shepherd’s Pie

  • 2 lb sweet potato (about 3 large), peeled and diced in half-inch cubes
  • 1/2 C grated Parmesan cheese
  • 2 T unsalted butter
  • 1 T fresh rosemary, finely chopped
  • 1/2 t cinnamon
  • 1 T canola oil
  • 1 yellow onion, diced
  • 2 large carrots, chopped
  • 1/2 lb crimini mushrooms, chopped
  • 1 C frozen green peas
  • 2 garlic cloves, minced
  • 1 lb lean ground turkey
  • 1/4 C tomato paste
  • 2 T Worcestershire sauce
  • 2 t dried thyme
  • salt to taste

Place sweet potato in a steamer basket set over 1 inch of water and steam until very tender, about 10 minutes. Alternatively, boil the potato cubes until tender. Mash potato with the cheese, butter, rosemary, cinnamon and a couple of pinches of salt. Set aside.

Preheat oven to 400 degrees Fahrenheit and grease an 11- x 8-inch casserole pan. Heat oil in a large skillet over medium. Add onion, carrot and mushrooms to pan; heat 10 minutes. Place green peas and garlic in pan; heat 1 minute. Stir in turkey, tomato paste, Worcestershire sauce and thyme. Heat until turkey is browned.

Place turkey mixture in baking pan and spread mashed sweet-potato mixture over top. Sprinkle some additional Parmesan on top. Bake for 30 minutes.
