Turkey Shepherd’s Pie Recipe
Prep Time: 25 minutes
Cook Time: 35 minutes
Servings: 4
Ingredients
- 6 cups peeled and diced sweet potatoes
- 2 cloves garlic
- ½ teaspoon salt
- ¼ cup milk
- 1 tablespoon butter
- 1 pound lean ground turkey, uncooked
- ½ cup diced onion
- 1¼ cups diced zucchini
- 1 cup finely diced carrots
- ½ cup frozen corn
- ¼ cup chicken broth
- 1 cup ketchup
- 2 tablespoons Worcestershire sauce
- ½ teaspoon dried poultry seasoning (or dried sage)
- Salt and freshly ground black pepper, to taste
Instructions
- Preheat: Heat the oven to 375°F (190°C).
- Cook the sweet potatoes: Place the diced sweet potatoes and the whole garlic cloves in a large saucepan. Cover with cold water and bring to a boil. Reduce heat and simmer, covered, for 15–20 minutes or until a fork slides through the sweet potato easily. Drain and return to the pot.
- Mash: Mash the sweet potatoes and garlic with the butter. Gradually stir in the milk and the ½ teaspoon salt until the mash is smooth and fluffy. Keep covered and warm.
- Prepare the filling: While the potatoes cook, brown the ground turkey with the diced onion in a large skillet over medium heat. Cook until the turkey is no longer pink and the onions are translucent. Drain any excess fat. Add the zucchini, carrots, corn, and chicken broth. Bring to a simmer, cover, and cook 10 minutes or until the vegetables are tender. Stir in the ketchup, Worcestershire sauce, and dried poultry seasoning. Season with salt and pepper and heat through.
- Assemble and bake: Spoon the turkey and vegetable filling into the bottom of an ungreased 1½-quart casserole dish (or divide among individual dishes). Spread the mashed sweet potatoes over the top, starting at the edges and working toward the center for an even layer. Bake uncovered for 35–40 minutes, until the casserole is heated through and the top is warmed. Makes about 4 servings.
About this recipe
This turkey shepherd’s pie was developed as a healthier casserole option without sacrificing comfort-food flavor. Lean ground turkey replaces traditional lamb or beef, and sweet potato mash adds natural sweetness, color, and vitamins. The filling is versatile — you can swap vegetables to match what’s in season or what you have on hand.
What is classic shepherd’s pie?
Traditionally, shepherd’s pie is a British baked dish made with ground lamb, mixed vegetables, and a mashed potato topping. This version uses turkey and sweet potatoes for a lighter, nutrient-dense variation while preserving the comforting layered casserole format.
Freezing and make-ahead tips
This recipe freezes well. Assemble the casserole (or individual portions), wrap tightly with plastic wrap and foil, and store in the freezer for up to one month. To bake from frozen, thaw overnight in the refrigerator and then bake until heated through, or bake from partially frozen adding extra time and covering loosely with foil until fully warmed.
Variations and substitutions
- Use ground beef instead of turkey for a more traditional flavor.
- Swap corn for any frozen vegetable mix (peas, green beans, mixed vegetables).
- Replace sweet potatoes with butternut squash, cauliflower mash, or regular white potatoes.
- Top with stuffing instead of mashed potatoes for a unique twist.
- Use fresh or dried sage in place of poultry seasoning.
- If zucchini is out of season, swap in red bell pepper or additional carrots.
- For individual servings, split the recipe among four small casserole dishes for easy reheating.
Helpful tips
- To prevent the mashed potatoes from sinking, let the turkey filling cool slightly before topping with hot mash.
- Spread mashed sweet potatoes beginning at the edges and work inward for an even seal and attractive finish. A piping bag can also be used for a decorative top.
- Adjust seasoning and the amount of broth to get a saucy, but not watery, filling.
