Ingredients

Potatoes

  • 2 pounds Yukon Gold Potatoes, thinly sliced

Cream Mixture

  • 1 ½ cups Heavy Cream
  • 1 bulb Roasted Garlic, mashed into a paste

Cheese

  • 1 ½ cups Gruyère Cheese, shredded
  • ½ cup Parmesan Cheese, grated

Other

  • 2 tablespoons Unsalted Butter
  • 1 teaspoon Salt
  • ½ teaspoon Black Pepper, freshly ground
  • 2 tablespoons Fresh Chives, chopped

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C). Lightly butter a medium baking dish to ensure the potatoes don’t stick and to add flavor.
  2. Infuse Cream with Roasted Garlic: In a saucepan, gently warm the heavy cream with the mashed roasted garlic paste. Stir gently to infuse the flavors without boiling, then remove from heat to keep the cream warm.
  3. Layer Potatoes and Cheese: Grease the baking dish with butter again if needed. Arrange a layer of thinly sliced potatoes vertically or slightly overlapping at the bottom of the dish. Sprinkle evenly with salt, black pepper, shredded Gruyère, and grated Parmesan. Repeat layering the potatoes and cheese mixtures until all ingredients are used, finishing with a layer of cheese on top.
  4. Add Cream and Bake Covered: Pour the warm roasted garlic cream mixture evenly over the layered potatoes. Cover the baking dish with foil and place it in the oven. Bake for 45 minutes to allow the potatoes to soften and flavors to meld.
  5. Uncover and Finish Baking: Remove the foil and continue baking for an additional 20 to 25 minutes until the top is bubbly, golden, and slightly crisp.
  6. Rest and Garnish: Take the dish out of the oven and let it rest for 10 minutes to set the sauce and make it easier to serve. Sprinkle freshly chopped chives on top for a fresh, herbaceous finish.
  7. Serve: Scoop out generous portions of the creamy, cheesy au gratin and serve hot as a hearty side dish to your favorite mains.

Notes

  • Use a mandoline slicer for perfectly even and thin potato slices, ensuring uniform cooking.
  • Warming the cream before pouring helps it absorb better into the potatoes, enhancing the dish's creaminess.
  • Allowing the dish to rest after baking thickens the sauce and improves texture.
  • Experiment with different cheeses like cheddar or fontina for a unique twist on flavor.
