Description

Creamy French Potato Gratin delivers comforting layers of sliced potatoes nestled in rich, velvety cheese sauce. Crisp golden edges and luxurious textures promise a memorable side dish you’ll savor with pure culinary delight.


Ingredients

Scale

Main Ingredients:

  • 4 medium russet potatoes, thinly sliced
  • 112 cups Cheddar cheese
  • 2 cups milk

Supplementary Ingredients:

  • 1 onion, sliced
  • 3 tablespoons butter
  • 3 tablespoons flour

Seasoning:

  • 12 teaspoons salt
  • Salt (to taste)
  • Pepper (to taste)

Instructions

  1. Preheat the oven to 400F (200C) and prepare a 1-quart baking dish with a light butter coating.
  2. Create the first layer of thinly sliced potatoes across the bottom of the dish, sprinkling with seasoning.
  3. Distribute finely chopped onions evenly over the first potato layer.
  4. Complete the layering with remaining potato slices, ensuring even coverage and adding another round of seasoning.
  5. In a saucepan, melt butter and incorporate flour and salt, stirring continuously for one minute to develop a roux.
  6. Slowly introduce milk while whisking, creating a smooth, creamy base and allowing the mixture to thicken slightly.
  7. Blend shredded cheese into the sauce until completely melted and integrated.
  8. Gently pour the cheese sauce over the layered potatoes, ensuring complete and even distribution.
  9. Cover the baking dish with aluminum foil to prevent excessive browning.
  10. Bake in the preheated oven for 90 minutes, watching for a golden, bubbling surface.
  11. Remove from oven and let the gratin rest for 10 minutes to set and cool slightly.
  12. Serve hot, allowing the creamy, cheesy potatoes to be the star of the meal.

Notes

  • Slice potatoes uniformly to ensure even cooking and consistent texture throughout the dish.
  • Use a mandoline or sharp knife to create thin, consistent potato slices for a smoother, more elegant gratin.
  • Experiment with different cheese varieties like Gruyère or sharp cheddar to add depth and complexity to the classic recipe.
  • Reduce baking time by 15-20 minutes for a lighter, less dense version that’s perfect for summer meals.
