Creamy, delicious, and topped with sweet potatoes, this shepherd's pie bakes in just one pan. To give it a twist from your usual shepherd's pie, make homemade turkey meatballs so this dish becomes extra special.
Preheat oven to 400 degrees F. Coat a 2-qt. rectangular baking dish with cooking spray. In a large bowl combine onion, cheese, 2 Tbsp. of the cilantro, the garlic, 1/4 tsp. salt, and 1/4 tsp. pepper. Add ground turkey; mix well.
Using 1 Tbsp. for each meatball, shape turkey mixture into 1 1/4-inch balls; place in prepared baking dish. Bake 15 minutes; cool slightly.
Pour Alfredo sauce over meatballs and liquid in dish; stir in peas. Layer sweet potato over mixture, overlapping slices. Brush with melted butter and sprinkle with 1/8 tsp. salt and 1/8 tsp. pepper.
Bake, covered, 30 minutes. Bake, uncovered, 10 minutes more or until potatoes are tender and sauce is bubbly. Cool on a wire rack 20 minutes. Sprinkle with remaining 1 Tbsp. cilantro.
