Ingredients You’ll Need

- 8-9 medium starchy potatoes (about 1.2kg), thinly sliced: Look for Russets or Yukon Golds for the best texture.
- 1 large head garlic, cut the top off: Roasting garlic transforms its flavor into something sweet and mellow.
- 1 cup (250 ml) heavy cream: This is what gives the gratin its luxurious texture.
- 1/4 cup (60 ml) whole milk: Helps lighten the cream while keeping it rich.
- 1 tablespoon unsalted butter, plus more for greasing the baking dish: Adds richness and flavor.
- 1 tsp fresh thyme leaves (or 1/3 tsp dried thyme): Fresh herbs elevate the dish beautifully.
- 1/4 tsp nutmeg: A pinch of nutmeg enhances the creaminess.
- 1/2 cup (40g) grated parmesan cheese, divided: Adds a salty, nutty flavor.
- 2 cups (about 220g) shredded Gruyère or mozzarella cheese: Choose Gruyère for a more complex flavor or mozzarella for a milder taste.
- Salt and pepper to taste: Essential for bringing all the flavors together.
- Fresh chives, for garnish: A pop of color and freshness.
How to Make Roasted Garlic Potatoes au Gratin

Let’s get cooking! Follow these simple steps to create your own masterpiece:
- Preheat your oven: Start by preheating your oven to 375°F (190°C) to set the stage for deliciousness.
- Roast the garlic: Cut the top off the head of garlic to expose the cloves. Place it on a piece of aluminum foil, drizzle with olive oil, and sprinkle a pinch of salt. Wrap it tightly and roast for about 30 minutes, or until soft and golden.
- Prepare the baking dish: Grease a 9×13-inch (23×33 cm) baking dish with butter and set it aside.
- Slice the potatoes: Peel and thinly slice the potatoes, ideally using a mandoline for even slices.
- Layer the potatoes: Arrange the sliced potatoes upright in layers within the baking dish; this not only looks stunning but also ensures even cooking.
- Make the creamy sauce: In a saucepan over medium heat, combine heavy cream, milk, butter, half of the grated parmesan, thyme, nutmeg, salt, and pepper. Heat until well combined, but don’t let it boil.
- Incorporate the roasted garlic: Once roasted, squeeze the garlic cloves out of their skins and mash into a paste. Stir this into the cream mixture until fully combined.
- Assemble the gratin: Pour the creamy mixture over the layered potatoes, ensuring they are evenly coated. Cover the dish tightly with foil.
- Bake: Place in the oven and bake for 1 hour and 15 minutes.
- Add more cheese: After the initial baking time, remove the foil, sprinkle the remaining cheese on top, and return to the oven uncovered for an additional 15 minutes or until the cheese is bubbling and golden brown.
- Cool and garnish: Once baked, let it cool for a few minutes, then garnish with fresh chives before serving.
Pro Tips for Perfect Roasted Garlic Potatoes au Gratin
Want to take your dish to the next level? Check out these expert tips!
- Choose the right potatoes: Starchy potatoes like Russets create the best texture, while waxy potatoes hold their shape but can be less creamy.
- Don’t skimp on the cream: For the ultimate indulgence, use heavy cream instead of milk. Trust me, it’s worth it!
- Layering is key: Make sure to layer the potatoes snugly; this helps with even cooking and flavor distribution.
- Experiment with cheeses: Feel free to mix and match your favorite cheeses to create a unique flavor profile.
- Let it rest: After baking, allow your gratin to rest for at least 10 minutes before serving. This helps the layers set and makes serving easier.
- Garnish generously: Fresh herbs like chives or parsley add a burst of color and fresh flavor to your dish.
- Broil for a crispy top: If you love a crunchy top, broil for an extra 2-3 minutes after baking—just keep an eye on it!
- Make it ahead: Prepare the dish up to the baking step, cover with foil, and refrigerate for up to 24 hours before baking.
- Freeze leftovers: If you have any leftovers (and that’s a big ‘if’), they freeze well. Just reheat in the oven when you’re ready to enjoy again!
- Adjust seasoning to taste: Always taste as you go! Adjust the salt and pepper as needed to suit your palate.
Common Mistakes and Troubleshooting
Even the best chefs face challenges! Here are some common pitfalls and how to avoid them:
- Potatoes not cooking through: Ensure your slices are evenly cut and thin. A mandoline can help!
- Gratin too watery: Avoid boiling the cream mixture; heat gently to combine ingredients.
- Cheese burning on top: If you notice the cheese browning too quickly, cover with foil and continue baking.
- Garlic flavor too strong: If you’re not a huge garlic fan, reduce the amount of garlic or roast it less for a milder taste.
Variations to Try
Want to mix things up? Here are some delightful variations to consider:
- Herb-infused: Add fresh herbs like rosemary or oregano for an aromatic twist.
- Spicy kick: Incorporate diced jalapeños or a pinch of cayenne pepper for a layered heat.
- Vegetable medley: Swap out some potatoes for thinly sliced zucchini or sweet potatoes for added flavor and nutrition.
- Smoky flavor: Add smoked cheese or a touch of smoked paprika to give your gratin a rich, smoky undertone.
Storage and Make-Ahead Instructions
Want to prepare in advance? Here’s how to store and make the most of your gratin:
- Refrigerate: Store any leftovers in an airtight container in the fridge for up to 3 days.
- Freeze: You can freeze portions in an airtight container for up to 3 months. Just reheat in the oven when you’re ready to enjoy!
- Make ahead: Assemble the gratin a day in advance, cover tightly with foil, and refrigerate. Bake when needed, adding an extra 10-15 minutes to the cooking time.
