Shepherd's Pie (Turkey version)

Mashed Potato Topping: 

3 large potatoes, peeled ¼ cup warm milk 2 tablespoons butter, room temperature salt and ground black pepper to taste 

Turkey Filling: 1 tablespoon olive oil 1 onion, chopped 1 pound ground turkey 1 (4.5 ounce) can sliced mushrooms 1 large carrot, shredded 1 tablespoon chopped fresh parsley 1 clove garlic, minced 1 teaspoon chicken bouillon powder ¼ teaspoon dried thyme salt and ground black pepper to taste 1 tablespoon all-purpose flour

Directions Start the topping:

Place potatoes in a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, 15 to 20 minutes. While the potatoes are cooking, preheat the oven to 375 degrees F (190 degrees C).

At the same time, make the filling: 

Heat olive oil in a skillet over medium heat; stir in onion. Sauté onion until soft and translucent, about 5 minutes. Stir in ground turkey, mushrooms, carrot, parsley, garlic, bouillon powder, and thyme.

Cook and stir until meat is broken up and cooked through, 5 to 7 minutes. Season with salt and pepper. Stir in flour and cook for 1 minute more. Remove from the heat and set aside. 

Finish the topping: Drain potatoes and transfer to a bowl. Add milk and butter and mash to desired consistency. 

Season with salt and pepper. Transfer filling to a deep-dish pie pan or casserole dish. Spread topping over filling and swirl with a fork.

Bake in the preheated oven until the topping is lightly browned, about 30 minutes.
