Ingredients

The following ingredients have 4 Servings
  • 6 medium russet potatoes, rinsed, peeled, and cut into 1/4-inch thick slices
  • 2 tbsp. unsalted butter
  • 1/2 c. diced yellow onion
  • 2 cloves garlic, minced
  • 2 tbsp. all-purpose flour
  • 2 c. half & half
  • 1 1/2 tsp. kosher sea salt
  • 1/4 tsp. ground black pepper
  • 1 1/2 c. total grated cheddar and colby jack cheese mixture (divided in half)
  • 1 tbsp. sliced chives (optional)

Instruction

  • 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.
  • 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.
  • 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. Add in 3/4 cups of the cheese mixture and whisk until the cheese is melted into the sauce.
  • Pour mixture over the potatoes. Top with the remaining 3/4 cup of the cheese mixture.
  • 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.
  • Let cool for 15 minutes before serving. Top with fresh chives, if desired.
