Directions

Prep 20 minCook 88 min

1
Heat the oven to 375°F. Lightly coat a 14-inch oval (or similar 3–3.5 qt) casserole dish with cooking spray.
2
Spiralize the carrots, turnips, and potato on a thick-noodle setting, trimming long strands to about 8 inches. Alternatively, slice very thinly with a mandoline or peeler.
3
In a small saucepan, combine the half-and-half, milk, thyme, rosemary, and about one-quarter of the salt. Bring to a gentle simmer over medium-low for 5 minutes, then remove from heat to steep.
4
Melt the butter in a large nonstick skillet over medium heat. Add the onion and garlic; cook until softened, about 5 minutes. Season with the remaining salt and the pepper, add the ground turkey, and cook over medium-high, breaking it up, until browned, 8–10 minutes.
5
Strain out the herb solids from the warm dairy, then pour it into the turkey. Simmer, stirring, for about 3 minutes to slightly thicken and coat the meat.
6
In a large bowl, combine the spiralized turnips, potato, and carrots with the turkey mixture. Toss until evenly coated.
7
Transfer to the prepared dish. Sprinkle evenly with the scallions and Gruyere.
8
Cover tightly with foil and bake for 1 hour. Uncover and broil on low until the top is golden, about 5 minutes. Let rest 5 minutes before serving.
