Ingredients
  

For the cream sauce

  • ¼ cup salted butter
  • 1 large yellow onion, diced
  • 2 cloves garlic, minced
  • ¼ cup all-purpose flour to remove the raw flour taste
  • 2 cups milk whole milk recommended
  • 1 cup chicken broth
  • ½ teaspoon salt divided
  • ⅛ teaspoon black pepper divided

For the layered potatoes

  • 3 pounds Yukon gold or red potatoes, sliced about ⅛-inch thick alternatively, use Russet potatoes
  • ¾ teaspoon salt divided
  • ¼ teaspoon black pepper divided

Instructions
 

Preparation

  • Preheat the oven to 350°F. Grease a 9×13-inch baking dish and set aside.
  • In a large saucepan, melt the butter over medium-low heat. Add the diced onion and minced garlic, cooking until the onion begins to soften, about 3 to 4 minutes.
  • Stir in the flour and cook for an additional 2 minutes to remove the raw flour taste.
  • Gradually whisk in the milk and chicken broth, adding a little liquid at a time and whisking constantly until smooth.
  • Increase the heat to medium and bring the sauce to a boil while whisking continuously. Stir in ½ teaspoon salt and ⅛ teaspoon pepper.
  • Allow the sauce to boil for 1 minute to thicken.

Layering and Baking

  • Layer one-third of the sliced potatoes in the prepared baking dish. Season with ¼ teaspoon salt and ⅛ teaspoon pepper. Pour one-third of the cream sauce over the potatoes.
  • Repeat the layering process two more times, seasoning each layer and finishing with sauce.
  • Cover the dish tightly with aluminum foil and bake for 45 minutes.
  • Remove the foil and bake for an additional 35 to 45 minutes until the potatoes are tender and the top is golden brown.
  • Optionally, broil for 3 to 4 minutes for a crispier top.
  • Let the scalloped potatoes rest for at least 20 minutes before serving.

Notes

Use a mandoline slicer for even potato slices. Adding cheese between layers is a great variation. Make sure to let the dish rest before serving.
