How to Make Roasted Garlic Potatoes au Gratin

Ready to create your masterpiece? Let’s get to the fun part—making this luxurious Roasted Garlic Potatoes au Gratin!

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C) and let the magic begin!

Step 2: Roast the Garlic

Cut the top off the head of garlic to expose those gorgeous cloves. Drizzle it with olive oil, season with a pinch of salt, and wrap it tightly in aluminum foil. Roast in the oven for about 30 minutes, until the cloves are soft and golden. Let it cool slightly—don’t burn those fingers!

Step 3: Prepare the Baking Dish

While the garlic works its wonders, grease a 9×13-inch (23×33 cm) baking dish to ensure your potatoes release beautifully.

Step 4: Slice the Potatoes

Peel and thinly slice your starchy potatoes. A mandoline slicer is your best friend here for those perfectly even slices!

Step 5: Layer the Potatoes

Take a stack of those splendid potato slices and arrange them upright in the greased dish, layering them snugly until the dish is filled to the brim.

Step 6: Make the Creamy Sauce

In a saucepan, combine the heavy cream, milk, butter, half of the grated parmesan, thyme, nutmeg, and a pinch of salt and pepper. Heat over medium until the butter melts, mixing everything together without letting it boil.

Step 7: Add the Roasted Garlic

Once your garlic is roasted, squeeze the sweet, caramelized cloves out of their skins and mash them into a paste. Stir this luscious paste into the creamy mixture until fully combined.

Step 8: Coat the Potatoes

Carefully pour the creamy garlic mixture over the layered potatoes, ensuring each slice is coated in that dreamy goodness. Cover the dish tightly with kitchen foil.

Step 9: Bake to Perfection

Bake the potatoes au gratin in the preheated oven for 40 minutes, letting those flavors meld beautifully.

Step 10: Cheese It Up!

Remove the foil and sprinkle the shredded Gruyère or mozzarella cheese along with the remaining parmesan cheese over the potatoes.

Step 11: Bake Until Golden

Return the dish to the oven, uncovered, and bake for an additional 30 minutes, or until golden brown and bubbly, with the potatoes fork-tender and calling your name.

Step 12: Cool and Garnish

Once done, take the dish out of the oven and let it cool for a few minutes. Garnish generously with fresh chives for a pop of color and flavor.

Step 13: Serve and Enjoy!

Scoop out a generous portion of those creamy, cheesy roasted garlic potatoes au gratin and revel in the deliciousness!
