Ingredients You’ll Need

- Whole milk: Softens the richness just enough for balance, so the potatoes don’t feel too heavy.
- Salt: Brings out all the subtle flavors in the potatoes, cheese, and garlic—seasoning is key here.

How to Make Roasted Garlic Potatoes au Gratin Recipe
Step 1: Roast the Garlic
Transforming raw garlic into a nutty, caramel-sweet paste is effortless and totally worth doing. Simply slice the top off an entire garlic head, drizzle it with olive oil, and wrap it snugly in foil. Slide it into a hot oven for about 35 to 40 minutes—your kitchen will start to smell incredible! When it’s done, the cloves will be soft and golden, just waiting to be squeezed out and mashed into a spreadable paste that’s ready to amp up your sauce.
Step 2: Prepare the Creamy Garlic Sauce
Once your roasted garlic is ready, grab a saucepan and melt the butter over medium heat. Stir in that glorious garlic paste until it’s completely combined. Next, whisk in the heavy cream, milk, salt, black pepper, and a whisper of ground nutmeg. Keep an eye on it—heat just until it’s barely simmering so the flavors can meld, then remove it from the heat before it boils. This step ensures your sauce is smooth, rich, and infused with garlic goodness from the start.
Step 3: Layer and Assemble
Grease a 9×13-inch baking dish to help avoid sticking and make serving a breeze. Arrange half the potato slices in the dish, overlapping slightly like shingles. Pour half of your creamy, fragrant garlic sauce over them, then scatter over half of each kind of cheese for a gooey, melty layer. Repeat with the remaining potatoes, pour the rest of the sauce, and finish with the last of the cheeses—each layer ensures every bite is packed with flavor.
Step 4: Bake to Perfection
Cover your masterpiece with foil and bake at 375°F for forty minutes. This gentle baking time lets the potatoes soak up all that sauce and become fork-tender. Then, for the magic: remove the foil and bake for another 20 to 25 minutes to let the top crisp up and turn gloriously golden-brown with bubbling edges. Let it rest for about 10 minutes after baking, so the sauce thickens and the slices hold their shape when served.
Step 5: Garnish and Serve
Just before serving, sprinkle with fresh thyme if you’re using it. The little green flecks look gorgeous against the golden top and add a lovely burst of herbal aroma. Now your Roasted Garlic Potatoes au Gratin Recipe is officially ready for the spotlight!

Garnishes
A sprinkle of freshly chopped thyme or chives is all you need for a pop of color and brightness. You could also try a dusting of extra Parmesan right out of the oven for even more golden crunch. For an extra-special occasion, add a light drizzle of truffle oil just before serving to really up the luxury factor.

Creative Ways to Present
Try baking individual portions in ramekins for a dinner party or holiday table—everyone loves having their own mini gratin. Feeling rustic? Serve straight from the baking dish, or use a ring mold to create tidy stacks for a more modern look. Either way, those layers will look stunning.
Make Ahead and Storage
Storing Leftovers
Leftover Roasted Garlic Potatoes au Gratin Recipe are an absolute treat. Cool any extras to room temperature, then transfer them to an airtight container. They’ll keep in the refrigerator for up to 3 days (if they last that long!).
Freezing
Want to stash some away for later? This dish freezes nicely! Let it cool completely, wrap portions tightly in foil and then plastic wrap, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating for best texture.
Reheating
To reheat, cover the dish with foil and warm in a 350°F oven until heated through—about 20 to 25 minutes. Uncover for the last few minutes to revive that signature golden top. You can also reheat slices in the microwave, though the oven yields the tastiest results.
FAQs
Can I use a different type Side Dish
Yukon gold potatoes are ideal for their buttery texture and thin skin, but you can substitute with russet potatoes if necessary. Peel russets first for the best result, and keep slices thin for even cooking and creaminess.
Do I have to roast the garlic, or can I use raw garlic?
Roasting garlic mellows its bite and deepens the flavor, making it sweet and creamy—a signature part of this dish. Raw garlic won’t offer the same richness, so take the extra time for roasting if you can!
Can this be made gluten-free?
Absolutely! The Roasted Garlic Potatoes au Gratin Recipe is naturally gluten-free—no flour required. Just double-check your cheeses to ensure they’re made without additives containing gluten.
How do I get perfectly thin, even slices?
A mandoline slicer is your secret weapon! It helps slice the potatoes evenly and quickly, which ensures uniform cooking and those beautiful layers. If slicing by hand, go slow and steady for best results.
Can I assemble the gratin ahead of time?
Yes, you can assemble the full dish (stop before baking), cover tightly, and refrigerate for up to 24 hours. Bring to room temperature before baking and enjoy all the convenience (and anticipation!).
