Ingredients for Cheesy Garlic Potatoes Gratin

Gathering these simple ingredients is the first step to creating this incredible potato gratin with cheese and garlic. The quality of your ingredients really shines through here!

  • 2 pounds Yukon Gold or Russet potatoes – peeled and thinly sliced (about 1/8-inch thick). Yukon Golds offer a creamy texture, while Russets provide a slightly starchier base.
  • 2 cups heavy cream – This is the base for our luscious sauce, providing richness and body.
  • 1 cup whole milk – Helps to lighten the cream slightly, creating a perfectly balanced sauce consistency.
  • 3 cloves garlic, finely minced or pressed – The star flavor! Fresh garlic is essential for that signature punch.
  • 2 tablespoons unsalted butter – Used to sauté the garlic and add a touch of richness to the sauce.
  • 1½ teaspoons salt, plus more to taste – Crucial for bringing out all the flavors.
  • ½ teaspoon black pepper – Freshly ground pepper adds a subtle warmth.
  • 1 teaspoon fresh thyme leaves (or ½ tsp dried thyme) – Thyme complements the garlic and cheese beautifully.
  • 1½ cups Gruyère cheese, freshly grated – Gruyère melts wonderfully and has a nutty, slightly sweet flavor that’s perfect for this dish.
  • 1 cup sharp cheddar cheese, freshly grated – Adds a familiar tang and beautiful golden color. Grating your own cheese is key!
  • ¼ cup Parmesan cheese, finely grated (optional, for topping) – For an extra savory crust.
  • Olive oil or butter, for greasing the baking dish – Prevents sticking and helps create a nice golden bottom.
  • Optional garnish: A few sprigs of thyme or chopped parsley for serving.

How to Make Cheesy Garlic Potatoes Gratin

Making this incredible cheesy garlic potatoes gratin is easier than you think! Follow these steps for a dish that’s bursting with flavor and comfort. The aroma alone will have everyone gathering in the kitchen!

  1. Step 1: Prepare the Potatoes. Start by peeling your potatoes and slicing them thinly, aiming for about 1/8-inch thickness. A mandoline slicer works wonders here for uniform slices, which is a technique often used in professional kitchens for consistent results. If you don’t have a mandoline, a sharp knife is perfectly fine too. Place the sliced potatoes into a large bowl filled with cold water and let them soak for about 15-20 minutes. This simple step is crucial for removing excess starch, which prevents the slices from clumping together and ensures you get that beautiful layered look in your potato gratin with cheese and garlic.
  2. Step 2: Make the Garlic Cream Sauce. In a medium saucepan, melt the 2 tablespoons unsalted butter over medium heat. Add the 3 cloves minced garlic and cook for just about a minute until you can smell its wonderful fragrance – be careful not to let it burn! Pour in the 2 cups heavy cream and 1 cup whole milk. Stir in the 1½ teaspoons salt, ½ teaspoon black pepper, and 1 teaspoon fresh thyme leaves. Let this mixture simmer gently for about 4-5 minutes, stirring occasionally, until it slightly thickens. This creates the base for our creamy garlic potato gratin recipe that’s rich and flavorful. Remove from heat and set aside.
  3. Step 3: Assemble and Bake. Preheat your oven to 375°F (190°C). Lightly grease your baking dish with butter or olive oil. Drain the soaked potato slices and pat them thoroughly dry with a clean kitchen towel. Begin layering the potatoes in your prepared dish, overlapping them slightly. Season each layer lightly with salt and pepper. Pour a portion of the garlic cream sauce over the potatoes and sprinkle generously with about half of the 1½ cups Gruyère cheese and 1 cup sharp cheddar cheese. Repeat this layering process until all potatoes and sauce are used, finishing with a final, generous layer of cheese on top. If using, sprinkle the ¼ cup Parmesan cheese over the very top. This layering ensures that every bite of your garlicky cheesy potato bake is packed with flavor.
  4. Step 4: Final Baking and Resting. Cover the baking dish tightly with aluminum foil. Place it in the preheated oven and bake for 35 minutes. This initial baking period allows the potatoes to steam and become tender without the cheese burning. After 35 minutes, carefully remove the foil. Continue baking for another 25-30 minutes, or until the top is beautifully golden brown and bubbling, and a knife inserted into the center easily pierces the potatoes. This second stage is where your baked cheesy garlic potatoes get that irresistible crispy topping. Once out of the oven, let the gratin rest for 10-15 minutes. This crucial resting period allows the sauce to thicken up, making it easier to serve neat slices.

Pro Tips for the Best Cheesy Garlic Potatoes Gratin

I’ve learned a few tricks over the years to make this dish truly spectacular. Follow these simple tips, and your cheesy garlic potatoes gratin will be the star of any meal!

  • Always use freshly grated cheese. Pre-shredded cheese has anti-caking agents that prevent it from melting smoothly, and you’ll miss out on that gorgeous, gooey texture.
  • Don’t skip the potato soaking step! Removing excess starch is key to preventing a gummy texture and ensuring those beautiful, distinct layers.
  • A mandoline slicer is your best friend for uniform potato slices, which cook evenly. If using a knife, take your time to get them as close in thickness as possible.

What’s the secret to perfect Cheesy Garlic Potatoes Gratin?

The real secret is in the layering and the sauce. Using a combination of heavy cream and milk creates the ideal richness for the sauce, and layering it with the cheese ensures flavor in every bite of your au gratin potatoes with garlic.

Can I make Cheesy Garlic Potatoes Gratin ahead of time?

Yes, you absolutely can! Assemble the entire dish up to 24 hours in advance, cover it tightly, and refrigerate. Just add about 10-15 minutes to the initial covered baking time when you’re ready to cook it.

How do I avoid common mistakes with Cheesy Garlic Potatoes Gratin?

The most common mistakes are not slicing potatoes thinly enough or not soaking them. Also, be careful not to overcook; the potatoes should be tender, not mushy. Finally, always let it rest after baking for the sauce to set.

Frequently Asked Questions About Cheesy Garlic Potatoes Gratin

What makes Cheesy Garlic Potatoes Gratin so creamy?

The creaminess comes from a combination of heavy cream and whole milk gently simmered with butter and garlic. This creates a rich, velvety sauce that infuses the potatoes as they bake. Grating your own cheese, especially Gruyère and cheddar, also contributes to a smoother, gooier texture compared to pre-shredded varieties. For more information on dairy, you can explore resources on dairy composition analysis.

Can I add other vegetables or cheeses to this recipe?

Absolutely! You can definitely customize this recipe. Sliced leeks or thinly sliced onions can be added along with the garlic for extra flavor. For cheeses, consider adding a touch of fontina or even a mild provolone for a different twist. Experimenting is part of how to make cheesy garlic potato gratin your own!

How can I make my Cheesy Garlic Potatoes Gratin less greasy?

To reduce greasiness, ensure you’re using potatoes that aren’t too starchy, like Yukon Golds. Also, be mindful not to over-pour the cream sauce; the goal is to coat the potatoes, not drown them. Draining excess fat after baking, if any appears, can also help. Using good quality cheese that melts well also means you need less to achieve that cheesy goodness.

What’s the best way to slice the potatoes for this gratin?

For the most consistent results when preparing your potato gratin with cheese and garlic, a mandoline slicer is ideal for achieving thin, uniform slices (about 1/8-inch thick). If you don’t have a mandoline, a very sharp knife and a steady hand will work. Uniformity is key because it ensures all the potato slices cook evenly in the creamy sauce.

Variations of Cheesy Garlic Potatoes Gratin You Can Try

While this classic cheesy garlic potatoes gratin is undeniably delicious, I love experimenting with different flavors and methods. Here are a few variations that are equally fantastic and offer a slightly different take on this comforting dish. These ideas will help you explore how to make cheesy garlic potato gratin your own!

  • Spicy Kick: Add a pinch of cayenne pepper or a finely minced jalapeño to the garlic cream sauce for a subtle heat that complements the cheese beautifully.
  • Herbed Delight: Incorporate other fresh herbs like rosemary or chives into the cream sauce along with the thyme. This adds another layer of aromatic complexity to your garlicky cheesy potato bake.
  • Dairy-Free Option: For a dairy-free version, use unsweetened cashew cream or full-fat coconut milk (the kind from a can) instead of heavy cream and milk. Use your favorite dairy-free shredded cheeses. This variation offers a similar richness to traditional scalloped potatoes with garlic and cheese.
  • Sweet Potato Twist: Swap half of the potatoes for sweet potatoes. Their natural sweetness creates a wonderful contrast with the savory garlic and cheese, making for a unique and delicious flavor profile.

Each forkful is rich, flavorful, and melts in your mouth, delivering comfort and indulgence in equal measure. This garlicky cheesy potato bake is a crowd favorite and a guaranteed hit.


Ingredients

Scale
  • 2 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced
  • 2 cups heavy cream
  • 1 cup whole milk
  • 3 cloves garlic, finely minced or pressed
  • 2 tablespoons unsalted butter
  • 1½ teaspoons salt, plus more to taste
  • ½ teaspoon black pepper
  • 1 teaspoon fresh thyme leaves (or ½ tsp dried thyme)
  • 1½ cups Gruyère cheese, freshly grated
  • 1 cup sharp cheddar cheese, freshly grated
  • ¼ cup Parmesan cheese, finely grated (optional, for topping)
  • Olive oil or butter, for greasing the baking dish
  • Optional garnish: A few sprigs of thyme or chopped parsley for serving

Instructions

  1. Peel and thinly slice the potatoes using a mandoline or a sharp knife (about 1/8-inch thick). Place them in a large bowl of cold water to soak for 15–20 minutes. This step removes excess starch and helps prevent the slices from sticking together.
  2. In a medium saucepan over medium heat, melt the butter. Add minced garlic and cook for about 1 minute until fragrant — don’t let it brown. Pour in the heavy cream and milk, then stir in salt, pepper, and thyme. Let the mixture simmer gently for 4–5 minutes, stirring often. Remove from heat and set aside.
  3. Preheat your oven to 375°F (190°C). Lightly grease your baking dish or cast iron skillet with butter or olive oil to prevent sticking and enhance browning.
  4. Drain the potato slices and pat them dry with a clean towel. Arrange one layer of potato slices at the bottom of the dish, slightly overlapping. Lightly season with a pinch of salt and pepper. Pour a bit of the garlic cream sauce over the top and sprinkle a small handful of Gruyère and cheddar cheese. Repeat layering until all potatoes, sauce, and cheese are used, finishing with a generous cheese layer on top. Add Parmesan if using.
  5. Cover the dish with aluminum foil and bake for 35 minutes. This allows the potatoes to steam and soften without over-browning.
  6. Remove the foil and continue baking for another 25–30 minutes, or until the top is golden brown and bubbling, and a knife easily pierces through the potatoes.
  7. Let the gratin rest for 10–15 minutes after baking. This helps the sauce thicken and makes it easier to slice. Garnish with a sprig of thyme or a sprinkle of chopped parsley before serving.

Notes

  • Grate your own cheese for the best melt and flavor — store-bought shredded cheese can be dry and coated with anti-caking agents.
  • Add a pinch of nutmeg to the cream sauce for a subtle depth that enhances the savory notes.
  • Let it rest before serving — this helps everything set and makes slicing much cleaner and easier.
