Step‑by‑Step Instructions for Roasted Garlic Potatoes au Gratin

Step 1: Preheat and Roast the Garlic
Begin by preheating your oven to 400°F (200°C). While it heats, slice the tops off the garlic heads to expose the cloves. Drizzle them with olive oil, then wrap each head in foil. Place them in the oven and roast for 30-35 minutes, until they are soft, golden, and fragrant. Once done, let them cool before squeezing the roasted garlic into a bowl and mashing it into a smooth paste.

Step 2: Prepare the Creamy Sauce
In a medium mixing bowl, combine the heavy cream and whole milk. Add the mashed roasted garlic, salt, black pepper, thyme, and paprika. Whisk the mixture thoroughly for about 1-2 minutes until all the ingredients are well blended and creamy. This luscious sauce will envelop the potatoes in rich, garlicky goodness, setting the stage for your Roasted Garlic Potatoes au Gratin.

Step 3: Layer the Potatoes
Take a greased 9x13 inch baking dish and begin layering by placing half of the thinly sliced Yukon Gold potatoes evenly across the bottom. Pour half of your prepared creamy sauce over the potatoes, ensuring they are well coated. Sprinkle half of both the Swiss and cheddar cheeses on top, allowing the flavors to meld beautifully in your Roasted Garlic Potatoes au Gratin.

Step 4: Repeat the Layers
Now, repeat the layering process with the remaining potatoes, pouring the rest of the creamy sauce over them. Top with the rest of the Swiss and cheddar cheeses, creating a deliciously cheesy crust. This second layer is crucial for achieving the perfect texture, marrying the flavors of the garlic and cheese with the tender potatoes.

Step 5: Bake to Perfection
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 45 minutes, allowing the potatoes to steam and soften. After this initial baking time, carefully remove the foil and let it bake uncovered for an additional 20-25 minutes. This will help the top achieve that gorgeous golden brown color and bubbly texture that makes Roasted Garlic Potatoes au Gratin irresistible.

Step 6: Let it Rest and Serve
Once out of the oven, let the dish sit for about 10 minutes to settle. This resting time allows the flavors to deepen and the cheese to firm up a bit. Just before serving, garnish with freshly chopped parsley for a pop of color and freshness. Your Roasted Garlic Potatoes au Gratin are now ready to delight your family and friends!

Make Ahead Options

These Roasted Garlic Potatoes au Gratin are perfect for meal prep enthusiasts! You can slice the Yukon Gold potatoes and store them in a bowl of cold water to prevent browning, making them ready for up to 24 hours. Additionally, the creamy sauce can be prepared ahead of time; just combine the heavy cream, whole milk, and seasonings, and refrigerate for up to 3 days. When you’re ready to serve, simply layer the potatoes with the sauce and cheeses in a baking dish, cover, and bake as directed. This prep ahead strategy not only saves you time but also ensures your dish comes out just as delicious as if you made it fresh on the spot!
