How to Make Purple Potato Gratin

  1. Preheat oven to 350°F (175°C).
  2. Make the gratin sauce: In a small saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 4 tablespoons of all-purpose flour and cook for 1 minute, stirring constantly.
  3. Gradually whisk in 2 cups of milk until smooth and thickened. Stir in 1 cup of shredded Gruyère cheese (or similar) until melted. Season with salt and pepper to taste.
  4. In a large skillet, heat 1 tablespoon olive oil over medium heat. Add 1/2 cup thinly sliced shallots and sauté until caramelized, about 5-7 minutes.
  5. Remove shallots from skillet and set aside. Add 4 slices of bacon to the skillet and cook until cooked through but not crispy. Remove from skillet, chop into 1-inch pieces, and set aside.
  6. Peel and thinly slice 2 pounds of purple potatoes.
  7. Grease a gratin dish (approximately 9x13 inches). Layer half of the sliced potatoes in the dish.
  8. Sprinkle half of the caramelized shallots over the potatoes, followed by the remaining potato slices.
  9. Pour the gratin sauce evenly over the potatoes, spooning it into any gaps. Top with remaining shallots, the parmesan cheese, and bacon pieces.
  10. Bake for 40-45 minutes, or until potatoes are tender and the top is golden brown and bubbly.
  11. Let rest for 5-10 minutes before serving. Enjoy!
