It’s a Saturday afternoon that smells of melted cheese and sweet smoke. The Maroilles starting to ooze over the edges of the dish, the quiet bubbling of cream beneath the crust—this northern gratin is not a recipe you dash off between meetings. It’s exactly the kind of dish you take the time to make when you have the kitchen to yourself.
Taken from the oven, the gratin presents with an irregular crust, golden in places, almost burned where the Maroilles has caramelized against the dish’s edge. Underneath, the potatoes have absorbed the cream and the fat from the cheese—they are melting, almost confit. The slices of smoked sausage have infused their aroma throughout, that smoky note tempering and complementing the intensity of the Maroilles. The first spoonful resists a second, then comes away with a soft, satisfying sound.

Ingredient Notes
Four ingredients that do all the work: potatoes, smoked turkey sausages, Maroilles, and good crème fraîche.
- Potatoes (1 kg) : They are the structure of the dish. For a melting result that holds well in the dish, prefer a firm-fleshed variety like Charlotte or Nicola—they withstand long cooking better than Bintje, which tends to disintegrate and disappear into the sauce. Cut into 3-4 mm slices, they cook evenly and retain some bite.
- Smoked turkey sausages (2 to 3) : They provide the meaty counterpoint and smoky note that balances the power of the Maroilles. Choose well-flavored sausages with a skin that snaps when bitten—avoid overly lean versions that dry out during cooking. A quick sear in the pan before assembly develops their flavor and allows them to release the water they would otherwise release into the dish.
- Maroilles (150 g) : This cheese gives the dish its identity. Its powerful flavor melts and spreads throughout the cream during cooking, without being aggressive once mixed with the other ingredients. For a milder taste, remove the orange rind before slicing—for authenticity, keep it, it brings a slight fermented bitterness that plays well with the richness of the cream.
- Full-fat crème fraîche (20 cl) : It binds the layers, hydrates the potatoes during cooking, and prevents the dish from drying out. Use full-fat crème fraîche with at least 30% fat—a lighter cream may curdle when heated and leave an unappetizing watery base. Whole milk can work as a substitute, but the result will be noticeably less creamy.
- Garlic (1 large clove) : It’s not visible in the dish, but you feel it in the background. The idea is to rub the gratin dish with the halved clove—the garlic doesn’t cook directly but leaves its aromas on the surface of the dish, which flavors every layer without ever dominating. If you like it more present, mince half a clove and slip it between two layers of potatoes.
The potatoes deserve a proper knife cut
Start by peeling the potatoes and cutting them into regular slices—3 to 4 mm thick, no more, no less. Too thick, they will remain firm in the center even after forty minutes in the oven. Too thin, they will disappear into the cream and you will lose all texture. A mandoline solves the issue in thirty seconds, but a sharp knife works perfectly if you take your time. Once cut, rinse them quickly under cold water to remove surface starch—this prevents them from sticking together during assembly and guarantees well-defined layers. If your slices exceed 4 mm, a ten-minute precook in boiling salted water is not superfluous: they will enter the oven already half-cooked and the final cooking will be even from top to bottom.
A minute in the pan, and the smoked sausages change dimension
Cut the sausages into 1 cm slices. Sauté them for two to three minutes over medium heat in a dry pan—they are already fatty enough on their own. The direct contact with the hot surface will create a slight caramelization on each side, a lightly colored edge that adds texture to the finished dish. Along the way, they will release some water: by removing it now, you avoid it ending up in your gratin and soaking the potatoes during cooking. The smell at this stage is already very appetizing—the smoke awakens, the pan bottom starts to color. That’s enough. No need to cook them completely; they will finish in the oven.
The assembly determines the gratin you will have in an hour
Preheat the oven to 180°C. Generously rub the gratin dish with the halved garlic clove—this takes twenty seconds and changes the aftertaste of the entire dish. Start with a layer of potato slices, slightly overlapping, then add a few sausage slices, then a few Maroilles slices. Repeat until you run out of ingredients. The idea is not to be obsessive about the uniformity of the layers, but to ensure that the cheese is well distributed at each level—it is the cheese that will melt and coat the potatoes during cooking. Finish with a top layer of potatoes, then pour all the crème fraîche in a steady stream over the top. It will slowly seep down between the layers in the oven, carrying the aromas of the Maroilles with it.
What the oven does while you’re not looking
Bake for 35 to 40 minutes. In the first twenty minutes, not much happens on the surface—the cream starts to heat, the potatoes soften gently, the Maroilles melts between the layers without being visible yet. Then around halfway through, it shifts: the smell of the cheese becomes distinct and fills the kitchen, the surface begins to color in places. To check doneness without cutting into the gratin, insert the tip of a knife into the center—it should sink in without resistance, like soft butter. If the top browns too quickly and the potatoes still seem firm, cover with aluminum foil and continue for five to ten minutes. Once out of the oven, let it rest for five minutes before serving—the cream stabilizes slightly, the layers hold better on the plate, and the flavors are clearer when hot than when scalding.
Tips & Tricks
- Cut the potatoes to a consistent thickness. Uneven slices cook at different speeds: the thin ones dissolve into the sauce while the thick ones still resist. A mandoline or patience with a good knife—both work, but you have to choose one and stick to it.
- Don’t salt before cooking. The Maroilles and smoked sausages are already quite salty—adding salt before the oven can make the dish frankly too salty after the flavors concentrate. Taste on the plate and adjust if necessary.
- Reheat in the oven rather than the microwave. In the microwave, the potatoes soften and the cream liquefies. At 160°C for twenty minutes with a splash of water poured into the dish, the gratin regains its texture, the crust reforms slightly, and the whole is almost as good as the day before.
- If you find the Maroilles too strong, mix it in equal parts with grated Gruyère. You keep the northern character of the dish but the taste is more accessible, and the crust browns even better thanks to the Gruyère which caramelizes easily.
Can I replace the Maroilles with another cheese?
Yes, if you can’t find Maroilles, a Munster or Livarot gives a similar result—same family of washed-rind cheeses, same way of melting. The taste will be different but the principle of the dish holds. Avoid mozzarella or Emmental alone, too mild; they don’t bring the character that makes this gratin interesting.
Can I prepare this gratin in advance?
Absolutely. You can assemble the entire gratin the day before, cover it with plastic wrap, and keep it in the refrigerator. Take it out twenty minutes before baking so it’s not too cold at the center, then add five minutes to the cooking time. The cream won’t have penetrated the layers yet, which sometimes gives an even more melting result after a night’s rest.
How to reheat the gratin without ruining it?
In the oven at 160°C for twenty to twenty-five minutes, with a little water poured into the dish before baking—the moisture prevents the potatoes from drying out. Cover with aluminum foil for the first ten minutes, then uncover to let the crust re-form slightly. The microwave works in a pinch but the potatoes soften and the cream loses its creaminess.
Do I have to precook the potatoes?
No, it’s optional if you cut them thinly, at 3 mm maximum. Thin slices cook completely in forty minutes in the oven without precooking. A ten-minute precook in boiling water becomes useful if you cut thicker or if your oven heats unevenly—it guarantees even cooking from center to edges.
Can I freeze this gratin?
It’s possible but not ideal. Fresh cream does not freeze well and can develop a grainy texture upon thawing. If you want to freeze, do so right after cooking and complete cooling, in individual portions. Thaw in the refrigerator overnight and reheat in the oven—the result remains edible, but less creamy than fresh.
What to serve with this gratin to make it a complete meal?
A green salad with a mustard vinaigrette is the classic accompaniment—the acidity cuts the richness of the dish. Simple crudités also work very well. No need to add starches or bread in quantity; the gratin is already very filling on its own.
Gratin with Maroilles and Smoked Sausages
French
Main course
A hearty gratin from northern France, with layers of melting potatoes, smoked turkey sausages, and Maroilles that melts into a creamy, flavorful sauce. Simple to assemble, boldly characterful.
Ingredients
- 1 kg firm-fleshed potatoes (Charlotte or Nicola)
- 300 g smoked turkey sausages (2-3 sausages)
- 150 g Maroilles
- 20 cl full-fat crème fraîche (30% min)
- 1 large garlic clove
- salt and black pepper from the mill
Instructions
- 1Peel the potatoes and cut them into regular 3-4 mm slices. Rinse them quickly under cold water to remove starch, then drain.
- 2Precook the slices in a large pot of boiling salted water for 10 minutes. They should be slightly tender but still firm. Drain and set aside.
- 3Cut the smoked sausages into 1 cm slices. Sauté them for 2 to 3 minutes over medium heat in a dry pan until lightly browned on the sides. Set aside.
- 4Slice the Maroilles into thin pieces. Remove the orange rind if you prefer a milder taste, keep it for a more authentic result.
- 5Preheat the oven to 180°C. Generously rub the inside of a gratin dish with the halved garlic clove.
- 6Place a first layer of potato slices in the dish. Add a layer of sausage slices, then a few Maroilles slices. Season lightly with pepper. Repeat until all ingredients are used, finishing with a layer of potatoes.
- 7Pour the crème fraîche in a steady stream over the entire surface. It will seep down between the layers during cooking.
- 8Bake for 35 to 40 minutes. The surface should be nicely golden and the tip of a knife inserted in the center should go in without resistance. If the top browns too quickly, cover with aluminum foil and continue for 5 minutes.
- 9Let rest for 5 minutes out of the oven before serving.
Notes
• No need to salt the dish before cooking: the Maroilles and smoked sausages already provide enough salt. Taste on the plate and adjust.
• For a milder version, replace half of the Maroilles with grated Gruyère—the character of the dish remains but is more accessible.
• The gratin keeps for 2 to 3 days in the refrigerator. Reheat at 160°C in the oven with a little water in the dish to maintain moisture.
