Turkey shepherd's pie with mashed sweet potatoes

Instructions

1. Preheat oven to 400ºF.
2. Place potatoes in a medium saucepan and pour in enough water to cover potatoes. Set pan over high heat and bring to a boil; boil until fork-tender, about 8 minutes. Drain potatoes; return potatoes to pan. Mash potatoes with buttermilk and garlic powder until smooth; season to taste with salt and pepper.
3. Meanwhile, heat oil in a large skillet over medium heat. Add onion and garlic; sauté until tender, about 3 minutes. Add carrots; sauté 1 minute. Remove vegetables from skillet; set aside.
4. Add sausage to skillet; sauté until browned, breaking up sausage as it cooks with a wooden spoon, about 5 minutes. Return vegetables to skillet; stir to combine. Add oregano, thyme and 1/4 teaspoon of black pepper; cook 1 minute. Add soup; simmer until liquid is absorbed and mixture is thick, about 2 minutes. Remove skillet from heat and spoon mixture into a 9-inch pie plate.
5. Spoon mashed potatoes over turkey mixture and spread into an even layer using the back of a wooden spoon.
6. Bake until filling is bubbly, about 25 minutes. Slice into 6 pieces and serve. Yields 1 piece per serving.
