Ingredients

Scale

Potatoes & Vegetables

  • 4 large Russet potatoes, peeled and sliced 1/8 inch thick
  • 1 medium onion, thinly sliced
  • 2 cloves fresh garlic, minced

Dairy & Fat

  • 2 cups heavy cream
  • 4 tablespoons unsalted butter, divided
  • 2 cups sharp cheddar cheese, shredded

Seasonings

  • Salt, to taste
  • Black pepper, to taste
  • Pinch of nutmeg (optional)

Instructions

  1. Prepare the Ingredients: Peel the Russet potatoes and slice them evenly about 1/8 inch thick using a mandoline or sharp knife for consistent thickness. Peel and thinly slice the onion and mince the garlic. This preparation ensures even cooking and layering.
  2. Make the Cream Sauce: In a saucepan over medium heat, melt 2 tablespoons of unsalted butter. Add the minced garlic and cook until fragrant, about 1 minute. Pour in the heavy cream and season with salt, pepper, and a pinch of nutmeg if using. Warm the mixture gently without boiling, allowing the flavors to meld together.
  3. Layer the Dish: Grease a baking dish with the remaining 2 tablespoons of butter. Arrange a layer of potato slices evenly on the bottom. Sprinkle some sliced onions and shredded cheddar cheese over the potatoes. Pour a portion of the cream sauce on top. Repeat the layering process—potatoes, onions, cheese, and cream sauce—until all ingredients are used, finishing with a generous layer of cheese on top.
  4. Bake Until Golden and Bubbling: Cover the baking dish with foil. Bake in a preheated oven at 350°F (175°C) for 45 minutes. Remove the foil and continue baking for an additional 15 to 20 minutes, or until the top is golden brown and the sauce is bubbling through the potatoes.
  5. Rest and Serve: Remove the dish from the oven and allow it to rest for 10 minutes before serving. This resting period helps the layers set for easier slicing and enhances the overall texture.

Notes

  • Use a mandoline slicer to achieve uniform potato slices for even cooking and texture.
  • Cook the dish low and slow to allow potatoes to soften perfectly and absorb the cream sauce.
  • Distribute cheese between layers and on top for a rich, melty experience.
  • Season each potato layer lightly with salt and pepper to build flavor throughout.
  • Let the scalloped potatoes rest after baking to firm up and make slicing neater.
