Sweet Potato Gratin

What You'll Need:

• 2 tablespoons butter
• 1/2 cup finely chopped onion
• 2 cups heavy cream
• 3/4 teaspoon dried thyme leaves
• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 4 pounds sweet potatoes, peeled, cut in half, then thinly sliced

Preheat oven to 400 degrees F. Coat a 2-1/2 quart casserole dish with cooking spray.

In a medium saucepan over medium heat, melt butter; saute onion 6 to 8 minutes, or until translucent. Stir in cream, thyme, garlic powder, salt, and pepper; simmer 5 to 7 minutes, or until hot.

In a large bowl, combine potatoes and cream sauce; mix well. Pour into casserole dish and cover.

Bake 30 minutes, then uncover, stir potatoes, and continue cooking 25 to 30 additional minutes, or until fork-tender and bubbly.
