Difficulty Level
Medium – Great for home cooks ready to elevate their side dish game with approachable techniques
Ingredients
- 3 large heads of garlic,whole
- 2 tablespoons olive oil
- 2 ½ pounds Yukon Gold potatoes,peeled and thinly sliced (about 1/8 inch thick)
- 1 ½ cups whole milk
- 1 cup heavy cream
- 4 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 1 ½ cups sharp white cheddar cheese,shredded
- 1 cup Gruyère cheese,shredded
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon fresh thyme leaves,finely chopped (optional)
- Fresh parsley,chopped,for garnish

Instructions
- Roast the garlic: Preheat oven to 400°F (200°C).Slice the tops off the garlic heads to expose cloves. Place on aluminum foil, drizzle with olive oil, wrap tightly, and roast for 40-45 minutes untill cloves are soft and caramelized. Let cool, then squeeze out the softened garlic to a paste.
- Prepare the potatoes: While garlic is roasting,peel and slice the Yukon Gold potatoes. Rinse slices in cold water to remove excess starch, then pat dry with paper towels to ensure even cooking and prevent sogginess.
- Make the cheese sauce: In a medium saucepan over medium heat, melt butter. Whisk in flour and cook, stirring constantly for 1-2 minutes, until pale golden and fragrant but not browned.
- Gradually whisk in the milk and heavy cream, ensuring a smooth mixture. Bring to a gentle simmer,stirring frequently until the sauce thickens and coats the back of a spoon,about 5-7 minutes.
- Reduce heat to low and stir in the roasted garlic paste,cheddar,Gruyère,salt,pepper,and thyme (if using). Stir until cheese melts completely and sauce is silky.
- Assemble the dish: Butter a 9×13-inch baking dish. Layer half of the potato slices evenly, pour half of the cheese sauce over, then repeat with remaining potatoes and sauce. Press down gently to ensure even layers.
- Finish baking: Cover with foil and bake in a preheated 350°F (175°C) oven for 40 minutes. Remove foil and bake another 10-15 minutes until top is golden brown and bubbling. If desired,broil for 2-3 minutes to intensify the golden crust-watch carefully to avoid burning.
- Remove from oven and let rest 10 minutes before serving to allow the sauce to set and intensify flavors.
Tips for Success: Elevate Your Creamy Roasted Garlic Potatoes au Gratin
- Potato Choice: Yukon Gold potatoes provide a buttery flavor and hold their shape well while becoming tender. Avoid starchy varieties like Russet, which break down too much.
- Garlic Roasting: For even deeper, sweeter garlic notes, roast the garlic low and slow wrapped in foil. You can prepare the garlic a day ahead to save time on the cooking day.
- Cheese Variations: Substitute Gruyère with fontina or mozzarella for a creamier melt, but maintain sharp cheddar for tangy balance.
- Make-Ahead: Assemble the dish a few hours ahead; keep covered in the refrigerator. Bring to room temperature before baking for an even cook.
- bubbling top Tip: A thin brushing of melted butter on the surface before baking encourages an irresistibly golden, crisp crust.
- Slicing Precision: Use a mandoline slicer for uniform potato thickness, which ensures even cooking and consistent creaminess throughout.
