Step‑by‑Step Instructions for Roasted Garlic Potatoes au Gratin
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C), allowing it to reach the perfect temperature for roasting. This prepares it to create that deliciously golden top on your Roasted Garlic Potatoes au Gratin. While the oven heats, gather your ingredients and equipment, including a baking dish and aluminum foil.
Step 2: Roast the Garlic
Cut the top off the head of garlic to reveal the cloves, then drizzle with 2 tablespoons of olive oil. Wrap the garlic in aluminum foil and place it in the oven for about 30-35 minutes or until it becomes soft and golden. Once done, let it cool before squeezing the roasted garlic into a bowl for mashing.
Step 3: Mix 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 black pepper, 1 teaspoon of thyme, and ½ teaspoon of paprika. Whisk until the ingredients are well blended, creating a flavorful base that will infuse your Roasted Garlic Potatoes au Gratin with richness.
Step 4: Layer the Potatoes
Grease a 9x13 inch baking dish to prepare for layering. Start with half of the thinly sliced 3 pounds of Yukon Gold potatoes, arranging them evenly across the bottom. Pour half of the creamy mixture over the potatoes, ensuring every slice is coated, then sprinkle half of the shredded Swiss and cheddar cheese on top for added indulgence.
Step 5: Repeat the Layering Process
For the second layer of your Roasted Garlic Potatoes au Gratin, add the remaining sliced potatoes evenly over the first layer. Pour the rest of the cream mixture over these potatoes, and top with the remaining Swiss and cheddar cheese. This double-layering technique guarantees a rich and cheesy experience in every bite.
Step 6: Bake Covered
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 and become tender while the flavors meld together beautifully. Keep an eye on the time; you'll know it's ready for the next step when a delicious aroma fills your kitchen.
Step 7: Bake Uncovered
After 45 minutes, carefully remove the foil from the baking dish. Continue baking for an additional 20-25 minutes until the top is golden brown and bubbly. The visual cue of a crisp, browned surface signals that your Roasted Garlic Potatoes au Gratin are nearing perfection and ready to impress everyone at your table.
Step 8: Let it Rest and Garnish
Once out of the oven, let your dish sit for about 10 minutes. This resting period allows the layers to set beautifully. Before serving, sprinkle with freshly chopped parsley to add a pop of color and freshness. Now, you're ready to delight your family and friends with this comforting and cheesy creation!

Expert Tips for Roasted Garlic Potatoes au Gratin
-
Choose the Right Potatoes: Yukon Gold potatoes are ideal for this dish due to their creamy texture. Avoid using starchy potatoes like Russets that can become mealy.

Roast Garlic Properly: Ensure you roast the garlic until it’s soft and caramelized to bring out its natural sweetness. Under-roasting can lead to a bitter taste.
-
Layering Technique: Always alternate layers of potatoes, cream, and cheese. This ensures even distribution of flavors and prevents the bottom layers from becoming soggy.
-
Watching Bake Times: Keep an eye on your dish during the last baking phase. The top should be golden brown and bubbly, but every oven is different—check at the 20-minute mark.
-
Let it Rest: Allowing the gratin to sit for about 10 minutes after baking helps it firm up, making it easier to serve while still being deliciously gooey.
