This elegant sweet potato gratin comes from Cooking Light’s Editor-in-Chief Hunter Lewis. Alternating layers of buttery-rich Yukon Golds and earthy sweet potatoes become even more delicious with Parmesan cheese and Gruyere cheese.

How to Make It

Step 1

Preheat oven to 350°F. Coat a 9- x 5- x 3-inch loaf pan with cooking spray.

Step 2

Combine first 6 ingredients in a bowl; toss.

Step 3

Add about 3 tablespoons milk to prepared pan. Arrange 1 layer of potatoes, shingle-style, over milk. Sprinkle with Parmesan. Repeat layers with remaining milk, potatoes, and Parmesan until pan is full. Top with Gruyère.

Step 4

Cover pan with foil; bake 35 minutes. Uncover; bake until browned and bubbly and knife slides easily through potatoes, about 30 more minutes. Cool for 45 minutes before serving.
