How to Make It

Preparing this ground turkey shepherd’s pie involves a few distinct steps, from cooking the savory filling to creating the creamy potato topping and finally baking it all together. The process is organized to ensure efficiency, allowing you to prepare components concurrently.

1. Preheat the oven to 400°F. Thoroughly grease a 9×13-inch casserole dish to prevent sticking.
2. Heat the olive oil in a large skillet over medium-high heat. Add the ground turkey and diced onion to the skillet. Sauté this mixture for 5–7 minutes, stirring occasionally, until the turkey is mostly cooked through and the onion has softened.
3. Add the minced garlic to the skillet and continue to stir for about 30 seconds until fragrant.
4. Stir in the dried rosemary, dried thyme, salt, pepper, coconut aminos, and tomato paste. Ensure all ingredients are well combined with the turkey mixture.
5. Pour in the chicken broth, then add the frozen mixed peas and carrots, and the corn. Stir everything together and cook for 5–7 minutes, allowing the vegetables to heat through and the flavors to meld.
6. In a small bowl, combine the arrowroot powder and water to form a smooth slurry. Add this slurry to the turkey filling in the skillet and stir continuously for about 30 seconds, or until the mixture has visibly thickened.
7. Transfer the thickened ground turkey filling into the prepared 9×13-inch casserole dish, spreading it out into an even layer across the bottom.
8. While the filling is cooking, prepare the mashed potato topping. Place the peeled and chunked russet potatoes in a pot of cold water and bring to a boil. Cook for 15–18 minutes, or until the potatoes are fork tender.
9. Drain the cooked potatoes thoroughly and return them to the empty pot. Add the butter or ghee, Original Nutpods or half and half, garlic powder, salt, and pepper. Mash the potatoes until they are smooth and well combined with the other ingredients. Once mashed, stir in the parmesan cheese.
10. Carefully spread the mashed potatoes evenly over the turkey filling in the casserole dish. If you are using shredded cheddar cheese, sprinkle it over the mashed potato topping at this stage.
11. Bake the assembled shepherd’s pie for 25–30 minutes, or until the topping is lightly browned and the filling is bubbling around the edges.

Thicken the Filling

A well-structured filling is key for any casserole, and for this ground turkey shepherd’s pie, the arrowroot slurry plays an important role. After the broth and vegetables have simmered, you’ll introduce a mixture of arrowroot powder and water. This combination creates a slurry that, when stirred into the hot filling, thickens it effectively.

The thickening process takes approximately 30 seconds of stirring after adding the slurry. This step ensures the ground turkey dinner filling maintains its consistency and doesn’t become watery under the mashed potato topping. This firm base keeps each serving neat and delicious.

Mashed Potato Topping

The creamy mashed potato topping is an essential component of this Ground Turkey Shepherd’s Pie. For the best result, russet potatoes are the go-to choice. They should be peeled, cut into uniform chunks, and boiled for 15–18 minutes until they are fork tender, ensuring easy mashing.

Once drained, return the potatoes to the pot and add butter or ghee, along with Nutpods or half and half for richness. Garlic powder, salt, and pepper round out the seasoning. Mash everything until smooth and then stir in the parmesan cheese. This creates a fluffy, flavorful topping that spreads evenly over the turkey filling, with an optional sprinkle of cheddar cheese for extra flavor before baking.

Make It Dairy Free

Adapting this ground turkey shepherd’s pie to be dairy-free is straightforward, making it an accessible menu item. The key is in selecting appropriate substitutions that do not compromise the texture or richness of the dish.

When preparing the mashed potato topping, use vegan butter instead of traditional butter or ghee. For the creamy liquid, Original Nutpods are an excellent dairy-free alternative to half & half. Instead of parmesan cheese, nutritional yeast offers a savory, cheesy flavor without any dairy. If you typically add shredded cheddar cheese for the topping, simply omit it or use a dairy-free shredded cheese product. These specific swaps help achieve a similar desirable outcome while keeping the dish dairy-free.

Make-Ahead and Freezing

This ground turkey shepherd’s pie is an excellent choice for those who appreciate the convenience of ground turkey meal prep and make-ahead meals. You can assemble the entire shepherd’s pie, including both the filling and the mashed potato topping, the day before you plan to bake it. Just cover the unbaked casserole and refrigerate it overnight. Before baking, let it sit at room temperature for about 15 minutes.

For longer storage, this freezer meal can be frozen after it’s fully cooked. Tightly cover the baked and cooled casserole with foil. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it, thaw the casserole in the refrigerator overnight. Individual portions can then be reheated in the microwave for 2–3 minutes. If reheating a full frozen casserole, bake it at 350°F for about 1 hour, or until heated through and bubbling.
