Creamy Potato Gratin Ingredients
For the Potato Layers
- Russet potatoes – choose starchy potatoes for tender, creamy layers that hold their shape beautifully.
- Garlic cloves – thinly sliced to infuse subtle, aromatic flavor into every bite.
- Salt – enhances the natural potato flavor and balances the creaminess.
For the Cream Mixture
- Heavy cream – the secret to that luscious, velvety texture that defines Creamy Potato Gratin.
- Whole milk – lightens the cream without losing richness for perfect silky consistency.
- Fresh thyme – adds a fragrant herb note that complements the creamy base.
For the Cheese Topping
- Gruyère cheese – melts perfectly to create a golden, bubbly crust that’s irresistibly savory.
- Parmesan cheese – adds a sharp, nutty finish and helps crisp the top layer.
Additional Essentials
- Butter – dotting the top before baking gives a rich, golden finish.
- Black pepper – freshly cracked to add a gentle kick without overpowering the creamy layers.
How to Make Creamy Potato Gratin
- Preheat your oven to 375°F (190°C) and generously butter a 9×13-inch baking dish to prevent sticking and promote a golden crust.
- Slice peeled russet potatoes into 1/8-inch rounds using a mandoline or sharp knife, ensuring uniform thickness for even, tender layers.
For the Cream Mixture: - Combine heavy cream, whole milk, garlic, thyme, salt, and pepper in a saucepan over medium heat until just steaming, about 3 minutes.
- Simmer gently for 2 minutes more, stirring often until tiny bubbles form around the edges—this infuses herbs and spices fully.
- Arrange a single layer of potato slices in the prepared dish, overlapping slightly, to create a stable, evenly covered base.
- Pour the warm cream mixture evenly over the potatoes, pressing lightly so each layer absorbs luscious, velvety goodness.
- Top with shredded Gruyère and freshly grated Parmesan, dotting with butter to achieve a bubbly, golden-brown finish as it bakes.
- Bake uncovered for 45–50 minutes, until the top is deeply golden and the potatoes are tender when pierced with a knife.
- Rest the gratin for 10 minutes before serving, allowing the creamy layers to set and making slicing clean and easy.
Optional: Sprinkle chopped chives for a fresh, colorful garnish.

Creamy Potato Gratin Recipe FAQs
What is the best type of potato for Creamy Potato Gratin?
Russet potatoes are your best friend here! Their starchy texture breaks down just enough to become tender and creamy while still holding their shape beautifully—perfect for those silky, luscious layers.
How should I store leftover Creamy Potato Gratin, and for how long?
Store leftovers in an airtight container in the fridge for up to 3 days. When ready to enjoy again, cover it with foil and reheat in a 350°F (175°C) oven until warmed through to keep that creamy texture intact.
Can I freeze Creamy Potato Gratin, and what’s the best way?
Absolutely! Wrap the cooled gratin tightly in plastic wrap, then wrap again with aluminum foil to prevent freezer burn. It will keep well for up to 2 months. When you want to eat, thaw it overnight in the fridge, then reheat in a 350°F oven for 20–30 minutes until bubbly and warm.
What if my potatoes aren’t cooking through evenly or the top burns before the inside is tender?
This happens when potato slices aren’t uniform or oven heat is uneven. Use a mandoline for even 1/8-inch slices, and consider covering loosely with foil halfway through baking to shield the top if browning too fast. Removing the foil near the end will bring back that gorgeous golden crust.
Is Creamy Potato Gratin safe for pets or those with lactose intolerance?
While irresistibly delicious, this gratin is not safe for pets because of cheese and dairy. For lactose intolerance, try lactose-free cream and cheese alternatives, or substitute with a rich cashew cream—this can still create a lovely, creamy texture without the dairy.
