This is a stunning side dish to serve company. The robust blend features earthy root vegetables in a lightly herbed cream sauce. It’s a perfect make-ahead dish for special occasions. —Carla Mendres, Winnipeg, Manitoba
3 medium russet potatoes, peeled
2 large carrots
2 medium turnips, peeled
1 large onion, halved
1 medium fennel bulb, fronds reserved
1/2 cup all-purpose flour
1 cup heavy whipping cream
1 tablespoon minced fresh thyme, plus more for topping
1 tablespoon minced fresh rosemary
1/2 teaspoon salt
1/2 teaspoon pepper, plus more for topping
1 cup shredded Asiago cheese, divided
Preheat oven to 350F. With a mandoline or vegetable peeler, cut the first 5 ingredients into very thin slices. Transfer to a large bowl; toss with flour. Stir in the cream, thyme, 1 tablespoon rosemary, salt and pepper.
Place half of the vegetable mixture into a greased 9-in. springform pan. Sprinkle with 1/2 cup cheese. Top with remaining vegetable mixture. Place pan on a baking sheet and cover with a double thickness of foil.
Bake until vegetables are tender and easily pierced with a knife, 1-3/4 to 2 hours. Remove from oven and top foil with large canned goods as weights. Let stand 1 hour. Remove cans, foil and rim from pan before cutting.
Top with remaining cheese. Add reserved fennel fronds and, as desired, additional fresh thyme and pepper. Refrigerate leftovers.
