Ingredients in Potatoes au Gratin
Let’s talk about the simple yet magic ingredients that come together to create this decadent dish. You don’t need anything fancy—just a few staples that pack a big punch.
- Potatoes: The star of the show! Creamy, starchy potatoes are the perfect base. Russet potatoes work beautifully because they hold up well and cook perfectly tender.
- Heavy Cream: This is where the magic happens! Heavy cream gives the sauce that rich, velvety texture that’s so satisfying. If you’re feeling a little indulgent, this is your moment to shine.
- Cheese: A combination of sharp cheddar and Gruyère cheese creates the perfect balance of creamy, nutty, and savory flavors. Plus, it melts beautifully on top, creating that irresistible golden crust.
- Butter: A little butter goes a long way to bring richness to the dish, both in the sauce and for greasing the pan. It’s all about that extra layer of flavor.
- Garlic & Herbs: A touch of garlic and fresh thyme (or rosemary, if you prefer) adds an earthy, aromatic flavor that elevates the dish to something special.
- Seasonings: Salt and pepper are all you need to bring everything together and let the flavors shine.

Instructions
Now let’s get to the fun part: making these Potatoes au Gratin! Follow these steps, and you’ll have a cheesy masterpiece in no time.
Preheat the Oven:
Start by preheating your oven to 375°F (190°C). This is crucial for ensuring even cooking and that perfect golden top.
Prep the Potatoes:
Peel and thinly slice the potatoes (about 1/8-inch thick). The thinner the slices, the creamier the dish will be. Arrange them in overlapping layers in a greased baking dish.
Make the Cream Sauce:
In a saucepan, melt butter over medium heat. Add minced garlic and cook for about 1 minute until fragrant. Stir in the heavy cream, salt, pepper, and fresh thyme (or rosemary). Bring the mixture to a gentle simmer, then remove it from the heat.
Assemble the Dish:
Pour the cream mixture evenly over the potatoes, making sure all the layers are covered. Top it off with a generous layer of grated cheddar and Gruyère cheese. The more cheese, the better, right?
Bake to Perfection:
Cover the dish with aluminum foil and bake for about 45 minutes. After that, remove the foil and bake for an additional 20 minutes, or until the top is golden and bubbly. The potatoes should be fork-tender when done.
Finishing Touches:
Once you remove the dish from the oven, let it cool for about 5 minutes before serving. This helps the flavors settle and makes it easier to serve.
Serve and Enjoy:
Scoop up that creamy, cheesy goodness and serve it warm. It’s the ultimate comfort food, and you won’t be able to resist going back for another helping!
How to Serve Potatoes au Gratin
These Potatoes au Gratin are perfect on their own, but if you want to make the meal extra special, here are a few ideas for pairing:
- Fresh Green Salad: A light, crisp salad with a tangy vinaigrette provides a refreshing contrast to the richness of the gratin.
- Grilled Meat or Chicken: Potatoes au Gratin pairs beautifully with roasted chicken, steak, or even grilled fish. The richness of the potatoes complements the savory flavors of the protein.
- Roasted Vegetables: Roasted Brussels sprouts, carrots, or green beans add a pop of color and extra nutrients to your meal.
- Crusty Bread: Serve with warm, crusty bread to soak up any leftover creamy sauce. You won’t want to leave any behind!
Additional Tips
Want to make this dish even more amazing? Check out these tips:
- Prep Ahead: You can assemble the potatoes and cream mixture ahead of time and store them in the fridge. When you’re ready to bake, just pop them in the oven.
- Spice It Up: If you like a little heat, add a pinch of cayenne pepper or red pepper flakes to the cream sauce for a subtle kick.
- Dietary Adjustments: If you’re looking for a lighter version, you can use half-and-half instead of heavy cream or try a dairy-free cream alternative for a vegan-friendly twist.
- Storage Tips: Leftovers? Store them in an airtight container in the fridge for up to 3 days. Reheat gently in the oven to keep the cheese nice and melty.
