How to Make Cheesy Garlic Potatoes Gratin

Step 1: Prep the Oven and Baking Dish

Start by preheating your oven to 375°F (190°C). While it heats up, generously grease your favorite baking dish with a pat of butter. This step guarantees easy serving and adds a subtle flavor boost that’s unmistakable.

Step 2: Infuse the Creamy Sauce

In a medium saucepan, combine the heavy cream, whole milk, minced garlic, salt, black pepper, and nutmeg. Warm this mixture over medium heat until just steaming (no need to boil). This is where all those gorgeous flavors come together, filling your kitchen with the scent of pure comfort.

Step 3: Layer the Potatoes and Sauce

Arrange half of your thinly sliced Yukon gold potatoes into the bottom of your prepared dish. Pour over half of the warm cream mixture, making sure every potato gets a little bath in the garlicky goodness. Scatter half the shredded cheddar and Parmesan cheeses over this first layer—it’s already looking irresistible!

Step 4: Repeat and Top with Cheese

Add another layer with the remaining potatoes, followed by the rest of the creamy sauce. Finish by sprinkling the last of the cheeses right on top. Finally, dot the surface with small pieces of unsalted butter for an extra golden touch as it bakes.

Step 5: Bake to Perfection

Cover your dish with foil and bake for 40 minutes. This creates the soft, melt-in-your-mouth layers you expect from a great Cheesy Garlic Potatoes Gratin. After 40 minutes, remove the foil and continue baking for another 20 minutes. This is when the edges get bubbly, and the top develops that irresistible golden hue.

Step 6: Let Cool and Serve

Once your gratin is beautifully browned and bubbling, let it cool for a few minutes before serving. This little pause helps the sauce thicken up, making for perfect slices and easy plating. Now you’re ready to enjoy every creamy, cheesy forkful!

To freeze, cut the cooled Cheesy Garlic Potatoes Gratin into portions and wrap individually or in an airtight, freezer-safe dish. It will stay fresh for a month. Thaw overnight in the fridge for best results.

Can I make Cheesy Garlic Potatoes Gratin ahead of time?

Yes, you can assemble the gratin a day ahead and keep it chilled, then bake just before serving. It’s a lifesaver for holidays or dinner parties.

What cheeses can I substitute?

You can swap in Gruyere, Swiss, or even a smoky gouda for a different flavor profile, but cheddar and Parmesan give classic results every time.

Can I make this recipe vegetarian?

It already is vegetarian, as long as your cheeses don’t contain animal rennet. It’s a hearty, satisfying dish for everyone at the table!

How can I get an extra crispy top?

Broil the gratin for 2-3 minutes after baking to get that picture-perfect golden crust. Just keep a close eye to prevent burning!
