1 Garlic head
1 tablespoon Olive oil
2-1/2 cups Whipping Cream
2 teaspoons Rosemary, chopped
2 teaspoons Thyme
2 teaspoons salt
3/4 teaspoon ground black pepper
2 pounds sweet potatoes, peeled, cut into 1/4" thick rounds
1 pound parsnips, peeled and cut into 1/4" thick strips
2 cups Gruyere cheese, shredded (can use Parmesan or Romano)

Steps:

Preheat oven to 375 degrees. Butter a 13x9x2" glass baking dish. Spray generously.
Cut 1/2" off the garlic head, so that all of the cloves are exposed. Drizzle with a little olive and place in a garlic baker. Roast the garlic in the oven for 25 minutes, or until the cloves are tender and golden brown. Remove the garlic head from the baker and squeeze all of the cloves out. Mash/chop the cloves on a cutting board with the back of your knife.
In a medium size bowl, whisk together the cream, garlic, rosemary, thyme, salt and pepper to blend.
Place half of the potatoes and parsnips in prepared baking dish, overlapping slightly. Sprinkle with 3/4 cup cheese. Top with second layer of potatoes and parsnips. Pour cream mixture over potatoes and parsnips in dish. Sprinkle with remaining cheese. Cover gratin with foil that has been sprayed with cooking spray and bake 1 hour. Uncover and bake until top is golden brown and potatoes and parsnips are tender, about 45 minutes longer. Let gratin cool 10 minutes before serving.
