Why You’ll Love This Crispy Parmesan and Gruyère Potato Gratin
- It’s comforting and elegant at once — the ideal side for holiday dinners and cozy weeknights.

- It holds up well as leftovers and reheats beautifully, which means more time for yourself and less for washing extra dishes.
Ingredients
Makes one 9×13-inch gratin (serves 6–8)
- 3 pounds Yukon Gold or Russet potatoes, peeled and thinly sliced (about 1/8-inch thick)
- 2 cups heavy cream (or 1 cup cream + 1 cup whole milk for a lighter touch)
- 2 cloves garlic, minced
- 1 tablespoon unsalted butter (plus extra for greasing)
- 1 teaspoon salt (more to taste)
- 1/2 teaspoon freshly ground black pepper
- Pinch of ground nutmeg (optional but lovely)
- 1 1/2 cups shredded Gruyère cheese, divided
- 1 cup finely grated Parmesan cheese, divided
- 1 cup panko breadcrumbs (optional, for extra crunch)
- 2 tablespoons fresh chives or parsley, chopped (for garnish)
Note on cheese: If Gruyère is hard to find, an aged Swiss or Emmental will do. For the Parmesan, a finely grated Parmigiano-Reggiano gives the best flavor.
Step-by-Step Instructions
Prep: Preheat your oven to 375°F (190°C). Butter a 9×13-inch baking dish well so the gratin slides out easily after baking.
Step 1 — Thin-slice the potatoes
Using a mandoline or a very sharp knife, slice your potatoes about 1/8-inch thick. Consistent thickness is the secret to even cooking. As you slice, place the potatoes in a bowl of cold water to keep them from browning.
Step 2 — Make the cream mixture
In a medium saucepan over low heat, warm the heavy cream with the minced garlic, salt, pepper, and nutmeg. Heat until fragrant and just starting to steam — don’t let it boil. Remove from heat and stir in 1 cup of the Gruyère and 1/2 cup Parmesan until melted and smooth. This step flavors the cream and helps the cheese integrate through the gratin for creaminess in every bite.
Step 3 — Layer the potatoes
Drain the sliced potatoes and pat dry with a clean towel. Arrange a single overlapping layer of potato slices in the prepared dish. Spoon about a quarter of the cheesy cream over that layer, spreading gently. Repeat: potatoes, cream, potatoes, cream, until you use all the potatoes and cream, finishing with a thin layer of cream.
Step 4 — Top it off
Sprinkle the remaining 1/2 cup Gruyère and 1/2 cup Parmesan evenly over the top. If you crave extra crunch, mix the panko breadcrumbs with a tablespoon of melted butter and scatter them across the cheese layer. The breadcrumbs will brown and give that irresistible crisp.
Step 5 — Bake
Cover the dish tightly with foil and bake for 40 minutes. Remove the foil and bake for another 20–25 minutes, until the top is bubbling and golden brown and a knife slides easily into the potatoes. If the top browns too quickly, tent with foil to prevent burning.
Step 6 — Rest and serve
Let the gratin rest 10–15 minutes before serving. The resting time helps the cream set a bit so your slices hold their shape. Garnish with chopped chives or parsley and serve warm.
Serving Suggestions
This gratin pairs beautifully with roasted or grilled proteins like lemon-herb chicken, pan-seared salmon, or even a simple roast pork tenderloin. For a cozy vegetarian meal, serve alongside braised greens or a crisp arugula salad to cut through the richness.

Cooking Tips & Tricks
- Slice evenly: A mandoline is a game-changer here. If you don’t have one, take your time with a sharp knife. Consistency = even cooking.
- Keep it creamy: If you’d like a lighter dish, substitute half-and-half for heavy cream, but know the final result will be a touch less silky.
- Make-ahead: Assemble the gratin, cover tightly, and refrigerate up to 24 hours. Add about 10–15 minutes to the baking time if you bake it straight from the fridge.
- Extra crisp top: Broil for 1–2 minutes on high after baking, watching closely so it doesn’t burn. The panko + Parmesan combo is especially happy under the broiler.
- Leftovers: Reheat in a low oven (350°F/175°C) until warmed through to keep that lovely texture. Microwave works in a pinch but can make it a bit softer.
Personal Anecdote
My sister Patricia and I stumbled into this exact combination one chilly November when guests were due to arrive and I’d misjudged the timing of our main. I grabbed what I had — potatoes, a knob of Gruyère Patricia had bought on a whim, and a wedge of Parmesan — and layered everything together. The cheese crust? Instant crowd-pleaser. From that night on, this gratin became our go-to for entertaining. It’s the kind of dish that makes you look like you planned ahead even when you didn’t.
FAQ
Q: Can I use a different cheese instead of Gruyère?
A: Yes. Aged Swiss, Emmental, or even a sharp cheddar will work. Gruyère gives a nutty, slightly sweet flavor that melts beautifully, but don’t be afraid to experiment.
Q: Can I make this gluten-free?
A: Absolutely. Omit the panko breadcrumbs, or choose a gluten-free breadcrumb. The gratin will still get a lovely cheesy crisp without them.
Q: How thin should the potatoes be?
A: Aim for about 1/8-inch thick. Too thick and they’ll take ages to cook evenly; too thin and the texture gets mushy. A mandoline makes this easy.
Q: Is this dish freezer-friendly?
A: You can freeze baked slices wrapped tightly for up to 2 months. Thaw overnight in the fridge and reheat in a 350°F oven until warmed through.
Q: What’s the difference between a potato gratin and scalloped potatoes?
A: “Potato gratin” often implies cheese (like Parmesan or Gruyère) and a crisper top, while “scalloped potatoes” are typically cooked in a milk or cream sauce without cheese. Both are delicious — this recipe leans into the gratin tradition with a crispy cheese finish.
Quick Troubleshooting
- Too watery? You likely had too much liquid or the potatoes weren’t layered tightly. Let it rest longer, and the sauce will thicken as it cools.
- Not brown enough? Move the dish under the broiler for 1–2 minutes. Watch it like a hawk — it goes from golden to burnt fast.
- Potatoes not soft? They might have been sliced too thick or oven temperature too low. Cover again and bake until tender.
Why this recipe works for busy cooks
This gratin is forgiving. You can prep it in stages, make it ahead, and it reheats like a dream. For busy American households — working parents, weekday entertainers, or anyone who wants a little culinary indulgence without drama — this dish delivers big on comfort and small on stress. The cheese melt makes it feel special; the hands-off baking time gives you room to tidy up, set the table, or check homework.
