Ingredients
Scale
- For the Roasted Garlic:
- 1 large head of garlic
- 1 tablespoon olive oil
- For the Potatoes:
- 2 pounds Yukon Gold potatoes (about 4–5 medium)
- 1 teaspoon salt, plus more to taste
- ½ teaspoon black pepper, plus more to taste
- For the Cream Sauce:
- 2 tablespoons unsalted butter
- 1 small yellow onion, finely minced
- 2 cloves garlic, minced
- 2 cups whole milk
- 1 cup heavy cream
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ⅛ teaspoon freshly grated nutmeg (optional)
- For the Topping:
- 1 ½ cups shredded Gruyère cheese (or a mix of Gruyère and Parmesan)
- ¼ cup panko breadcrumbs (optional, for extra crunch)
Instructions
- 1. Preheat oven to 400°F (200°C). Slice off the top ¼ inch of the garlic head, drizzle with olive oil, wrap in foil, and roast for 30-40 minutes until soft. Squeeze out the cloves, mash into a paste.
- 2. Wash, peel, and thinly slice potatoes (about ⅛-inch thick). Toss with 1 tsp salt and ½ tsp pepper.
- 3. Melt butter in a saucepan over medium heat. Sauté minced onion until softened (5-7 min). Add minced garlic and cook for 1 minute until fragrant.
- 4. Pour in milk and heavy cream. Stir in roasted garlic paste, ½ tsp salt, ¼ tsp pepper, and nutmeg (if using). Bring to a gentle simmer and cook for 5 minutes, stirring occasionally, until slightly thickened.
- 5. Lightly butter a 9×13 inch baking dish. Layer half the potatoes, pour half the sauce over, and sprinkle with half the cheese. Repeat with remaining potatoes, sauce, and cheese.
- 6. Cover dish tightly with foil and bake for 30 minutes.
- 7. Remove foil. If using panko, sprinkle over the cheese. Bake for another 20-30 minutes, until potatoes are tender and top is golden brown and bubbly.
- 8. Let rest for 10-15 minutes before serving.
Notes
Store completely cooled leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat in a moderate oven at 325°F (160°C) covered with foil for 15-25 minutes, or until heated through and bubbly.
