Ingredients

  • 2 pounds Yukon Gold Potatoes or Gold Potatoes peeled and sliced
  • 1 small yellow onion peeled and sliced
  • 3 Tablespoons butter
  • 4 large garlic cloves minced
  • 1/4 cup all-purpose flour
  • 1 cup chicken broth
  • 2 cups whole milk
  • 1 teaspoon Kosher salt
  • 1/2 teaspoon black pepper
  • 2 cups freshly-grated sharp cheddar cheese (or more if you please)
  • 1/2 cup grated Parmesan cheese

Instructions

  1. Prepare Cream Sauce

    Preheat oven to 400 degrees Fahrenheit. Grease a 2-quart baking dish with cooking spray and set aside. Melt butter in a medium saucepan on medium heat. Add onion and sauté for 4-5 minutes. Add minced garlic and stir for an additional minute. Gradually add flour and stir until well combined. Add chicken broth, salt, pepper, and stir until smooth. Slowly add milk and continue stirring until combined. Simmer over low heat for 1-2 minutes stirring constantly.

  2. Prepare Potatoes

    Spread half of the potatoes evenly in baking dish. Pour half of the cream sauce over potatoes. Sprinkle with Parmesan cheese and 1-cup of the grated cheese. Place the rest of the potatoes on top. Cover with remaining cream sauce and cheese.

  3. Bake

    Cover baking dish with foil and bake for 45-minutes. Hint: not a bad idea to place a sheet of foil on oven rack under the baking dish in-case the cream sauce should boil over. Remove foil and continue baking uncovered for 30-minutes or until potatoes are cooked through. Remove from oven and allow resting time of 10-minutes prior to serving. Enjoy!
