Method
Make the potato topping
- Heat the oven to 400°F.
- Put the potatoes in a large saucepan and cover with cold water by 1 inch.
- Bring the water to a boil, then simmer for 15–20 minutes until the potatoes are fork-tender.
- Drain the potatoes and return them to the saucepan.
- Mash with 3 tablespoons butter, the milk, and 1 teaspoon salt until smooth.
Cook the filling
- Heat the olive oil in a 12-inch skillet over medium heat.
- Add the onion and carrots and cook for 5 minutes, stirring occasionally.
- Add the turkey and cook for 8–10 minutes, breaking it up, until browned and it reaches 165°F.
- Stir in the garlic and cook for 30 seconds.
- Mix in the tomato paste, flour, and thyme.
- Stir in the Worcestershire sauce, chicken broth, remaining 1/2 teaspoon salt, and pepper.
- Simmer for 3–5 minutes, stirring, until the sauce thickens.
- Stir in the peas and cook for 2 minutes.
Assemble and bake
- Grease a 9x13-inch baking dish with the remaining 1 tablespoon butter.
- Spoon in the filling.
- Spread the mashed potatoes evenly over the top.
- Bake for 20–25 minutes, until the filling is bubbling and the topping is golden; check that the center reaches 165°F.
- Let the shepherd’s pie rest for 10 minutes before serving.
Notes
For a smooth topping, mash the potatoes until no lumps remain. Refrigerate leftovers for 3–4 days; freezing is suitable for up to 3 months. For a dairy-free variation, use plant-based butter and unsweetened plant milk.
