This Ground Turkey Shepherd's Pie is made in a cast iron skillet with tender ground turkey, flavorful vegetables, and fresh herbs for the best tasting shepherd's pie you'll ever try.
Preheat the oven to 400°F. Add diced potatoes and crushed garlic cloves to a pot and cover them with cold water. Bring the water to a boil over medium-high heat and boil the potatoes for 10 minutes or until they're fork tender. Remove from heat and drain completely.
2 large russet potatoes, 2 cloves garlic
Transfer the drained potatoes and garlic back into the cooking pot and add butter, salt, and pepper. Mash until smooth using a potato masher or fork. Stir in half and half until well combined. Set aside.
4 tablespoons unsalted butter, 1 ½ teaspoons kosher salt, 1 teaspoon black pepper, ½ cup half and half
Make the Ground Turkey Shepherd's Pie
Melt butter in a cast iron skillet over medium heat. Add the diced onion, carrot, peas, and corn and cook, stirring occasionally, for 5-7 minutes or until softened and beginning to brown. Add the garlic, herbs, salt, and pepper and cook for an additional 1-2 minutes.
2 tablespoons unsalted butter, ½ large yellow onion, 2 large carrots, 1 cup sweet corn, ½ cup green peas, 3 cloves garlic, 2 teaspoons fresh thyme leaves, 1 teaspoon fresh rosemary, ½ teaspoon kosher salt, ½ teaspoon black pepper
Push the vegetables aside in the skillet and add the ground turkey. Cook the turkey, breaking it up with a wooden spoon, until most of the liquid has evaporated and the turkey is no longer pink.
1 ¼ pounds ground turkey
Add the flour, tomato paste, and soy sauce to the ground turkey mixture and stir well to combine. Pour in the chicken stock and simmer until slightly thickened. Remove the skillet from the heat. If using a casserole dish, transfer the filling to the casserole dish.
1 tablespoon all-purpose flour, 1 tablespoon tomato paste, 1 teaspoon low-sodium soy sauce, ½ cup chicken stock
Dump the mashed potatoes on top of the filling and use a fork to spread them out evenly. Bake for 25-30 minutes or until the filling is bubbly and the mashed potatoes are golden-brown. Cool for 15 minutes before serving.
