A comforting and easy scalloped potatoes recipe featuring roasted garlic and parmesan in a creamy sauce, perfect for holidays or weeknight dinners.

Ingredients

Scale
  • 2 pounds russet potatoes, peeled and thinly sliced
  • 1 whole bulb garlic, roasted until soft and caramelized
  • 1 cup freshly grated parmesan cheese (about 100g)
  • 2 cups heavy cream (480ml)
  • 4 tablespoons unsalted butter (55g)
  • 1 teaspoon fresh thyme, finely chopped (optional)
  • Salt and black pepper to taste
  • 2 tablespoons all-purpose flour (15g)
  • 1/2 cup milk (120ml)

Instructions

  1. Preheat oven to 400°F (200°C). Slice the top off the garlic bulb, drizzle with olive oil, wrap in foil, and roast for 35-40 minutes until soft and golden. Cool and mash the roasted garlic cloves into a paste.
  2. Peel and thinly slice potatoes about 1/8 inch (3 mm) thick using a mandoline or sharp knife.
  3. In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for about 1 minute, stirring constantly to form a roux.
  4. Slowly whisk in heavy cream and milk. Stir until sauce thickens slightly, about 4-5 minutes. Remove from heat and stir in mashed roasted garlic, parmesan, thyme, salt, and pepper. Add more milk if sauce is too thick.
  5. Butter a 9×13 inch (23×33 cm) baking dish. Layer half the potato slices evenly on the bottom. Pour half the cream sauce over the potatoes. Add remaining potato slices and pour remaining sauce on top. Sprinkle an additional 1/4 cup (25g) parmesan over the surface.
  6. Cover with foil and bake at 375°F (190°C) for 45 minutes.
  7. Remove foil and bake uncovered for 20-25 minutes until top is golden and bubbly. Let rest for 10 minutes before serving.

Notes

Use a mandoline for uniform potato slices to ensure even cooking. Roasting garlic softens its sharpness and adds a mellow, caramelized flavor. Cover the dish with foil during the first baking stage to steam potatoes gently, then uncover to brown the top. If sauce is too thin after baking, broil for 2-3 minutes to thicken and crisp the top, watching carefully to avoid burning.
