Instructions
Over medium-high heat, bring a large pot of water to boil. Add the potatoes and let cook for 15 minutes or until the potatoes are fork-tender.
Drain and add ½ cup milk, 3 tablespoons butter, ⅓ cup Parmesan cheese, 1 teaspoon salt, and ½ teaspoon black pepper. Mash to combine and set aside.
While the potatoes cook, in a large skillet, melt the butter over medium-high heat. Add the turkey and onion. Cook for 6 minutes, breaking up the meat with a spatula as it cooks.
Add the carrots, tomato paste, Worcestershire sauce, garlic, and remaining salt to the meat. Cook for 9 minutes or until the carrots are softened.
In a small bowl, whisk the flour or tapioca starch with the chicken broth until the starch is dissolved to create a "slurry".
Add the slurry to the skillet, along with the peas and dried thyme. Stir to combine and reduce the heat to low. Bring to a simmer and cook for an additional 3 minutes.
Spread the mashed potatoes over the turkey mixture and top with the remaining Parmesan cheese. Simmer for 3 to 5 minutes or until the potatoes are heated through.
Remove from heat, top with chives, and serve.
Notes
For a cheesy crust on top of the potatoes, set your oven on broil. Sprinkle ½ cup of shredded cheese over the mashed potatoes and place the oven-safe skillet in the oven. Broil for 2 minutes or until the cheese is melted and lightly browned.
