How to Make Roasted Garlic Potatoes Au Gratin
Roast the Garlic: Preheat your oven to 350 °F (180 °C). Cut the tops off the garlic heads, drizzle with olive oil, and wrap them in foil. Roast for 30 minutes, until they re soft and fragrant.
Prepare Potatoes: Peel and slice the potatoes thinly using a mandoline for even thickness. Arrange them upright in a greased 9Ã13-inch baking dish, making sure they re snugly packed.
Make Creamy Sauce: In a medium saucepan, combine heavy cream, whole milk, butter, half of the parmesan cheese, thyme, nutmeg, salt, and pepper. Heat gently until the butter melts, then stir in the sweet roasted garlic, creating a creamy mixture.
Combine and Bake: Pour your delicious sauce over the potatoes. Cover the dish with foil and bake for 40 minutes. Afterward, remove the foil, sprinkle on the remaining cheese, and bake uncovered for another 30 minutes until the top is golden brown and bubbly.
Optional: For additional flavor, sprinkle some extra fresh thyme on top before serving.
