If you’re looking for a rich and savory side dish for your holiday party, look no further than this Yukon and Sweet Potato Au Gratin from Executive Chef Wally Weaver of Salt Creek Grille – Princeton. This dish will warm your guests up with butter, Asiago, Parmesan, and heavy cream. Chef Weaver’s cheesy, indulgent side dish only takes 30 minutes to prep!

Ingredients

3  tablespoons unsalted butter
5  cups heavy cream
1½ cups grated Asiago
1½ cups grated Parmesan
6 large Yukon Gold potatoes, peeled
1 sweet potato, peeled
Salt and freshly ground black pepper, for seasoning
3  tablespoons fresh thyme and rosemary

Directions

    1. Heat oven to 300°F and generously butter a 9-by-13-inch baking pan or shallow gratin dish.   
    2. In a medium pot, bring cream, herbs and a pinch of salt to a simmer. Simmer until reduced by ¼, about 10 minutes.  
    3. Strain the cream and reserve the mixture. Mix the two cheeses together.
    4. Using a mandoline, slice the potatoes into 1⁄8-inch-thick rounds.
    5. Ladle a thin layer of cream on the bottom of the dish. Place 1 layer of potatoes in the pan, slightly overlapping as you go, and completely covering the bottom.
    6. Sprinkle with salt and pepper (not too much pepper!), then pour some of the cream mixture over potatoes.
    7. Top with a level layer of the cheese mixture.
    8. Make 2 additional layers with the Yukon potatoes and then 1 layer of the sweet potato and then 3 more layers of Yukon potatoes. Don’t put cheese on the top (you will add a top layer of cheese later). Press down to compact the potatoes.
    9. Cover and bake until potatoes are tender, about 2½ hours, then sprinkle top with remaining cheese and bake until browned and bubbling, 10 to 15 minutes.
    10. Garnish with herbs. Let cool slightly, then serve.
