Step‑by‑Step Instructions for Roasted Garlic Potatoes au Gratin
Step 1: Roast the Garlic
Preheat your oven to 400°F (200°C). Cut the top off a head of garlic to expose the cloves, drizzle with olive oil, and wrap it snugly in foil. Place the wrapped garlic in the oven and roast for about 30-35 minutes until it’s soft, golden, and fragrant. Once done, let it cool slightly before squeezing the roasted garlic into a bowl and mashing it into a smooth paste.
Step 2: Prepare the Cream Mixture
In a mixing bowl, combine 1 cup of heavy cream, 1 cup of whole milk, the mashed roasted garlic, 1 teaspoon of salt, ½ teaspoon of pepper, 1 teaspoon of thyme, and ½ teaspoon of paprika. Whisk the mixture until all ingredients are well blended, ensuring a creamy texture that will envelop the potatoes in rich flavor as you make your Roasted Garlic Potatoes au Gratin.
Step 3: Layer the Potatoes
Grease a 9x13 inch baking dish to prevent sticking. Start by layering half of the thinly sliced Yukon Gold potatoes evenly at the bottom of the dish. Pour half of the creamy mixture over the potatoes, followed by a handful of both shredded Swiss and cheddar cheeses. Repeat this process with the remaining potatoes, cream mixture, and cheeses, ensuring a deliciously layered effect.
Step 4: Bake and Brown
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for about 45 minutes, allowing the potatoes to cook through and absorb the creamy flavors. After 45 minutes, carefully remove the foil and continue baking for an additional 20-25 minutes, or until the top is golden brown and bubbly, providing that enticing oven-fresh aroma.
Step 5: Rest and Garnish
Once the baking time is complete, take your Roasted Garlic Potatoes au Gratin out of the oven and let it sit for about 10 minutes. This resting period helps the dish set and makes it easier to serve. Finally, garnish with freshly chopped parsley to add a touch of color and brightness, elevating your delicious creation even further.
