Step 1

Preheat oven to 350 degrees. Lighty spray or butter a 9x13-inch baking dish. Arrange potatoes by fanning them in three lines across the pan. Set aside.

Step 2

In a medium saucepan set over medium heat, add the butter. Once melted add the onion and saute for 3-5 minutes or until tender. Add the garlic and continue cooking for 1 additional minute.

Step 3

Whisk in the flour, cook until lightly golden in color, then slowly pour in the half & half, whisking until all of the liquid has been incorporated. Whisk in salt and pepper.

Step 4

Pour mixture over the potatoes. Top with cheese.

Step 5

Cover with aluminum foil and bake for 45 minutes. Remove the foil and continue baking for 15-30 minutes or until golden brown and potatoes are fork-tender.

Step 6

Let cool for 15 minutes before serving. Top with fresh chives, if desired.
