Slovak French Potatoes (Francúzske zemiaky) with Sausage and a Crispy Cheese Crust
A traditional Slovak potato casserole with eggs, cream and a deeply golden, crispy cheese topping
Francúzske zemiaky, literally “French potatoes”, are a classic of Slovak and Central European home cooking. Layers of potatoes, hard-boiled eggs, sausage and cream have been served at family tables for generations.
The name, however, is slightly misleading. What Slovaks call French potatoes is essentially a Central European potato casserole – and the French probably have no idea about our “French potatoes” at all.
The key to making them particularly good is contrast. The inside should remain soft, creamy and juicy, while the top should develop a deeply golden and crispy crust.
In this recipe, the potatoes are therefore baked with the creamy egg mixture first. The cheese is added only towards the end, when the temperature is increased to create that irresistible crispy topping.
Smoked sausage is the traditional choice, but you can easily replace it with diced cooked ham for a lighter version or leave out the meat completely for a vegetarian variation.
Why this Slovak potato casserole works
• potatoes cooked in their skins retain more flavour and hold their shape during baking
• sour cream provides creaminess and a pleasant tang
• eggs bind the individual layers together
• smoked sausage adds paprika, smokiness and richness
• cheese is added towards the end rather than at the beginning
• higher heat during the final stage creates a golden, crispy cheese crust
Ingredients for Slovak French Potatoes
Potato casserole
• 1.2 kg potatoes, preferably waxy or all-purpose
• 5 hard-boiled eggs
• 250–300 g good-quality smoked sausage
• 1 medium onion
• 1 tbsp butter, for greasing the baking dish
• salt
• freshly ground black pepper
Cream mixture
• 250 ml sour cream
• 150 ml cooking cream
• 2 eggs
• salt
• freshly ground black pepper
For the crispy cheese crust
• 120–150 g cheese, such as Gouda, Edam or Cheddar
• 1–2 tbsp fine breadcrumbs, optional
Lighter version
Replace the sausage with:
• 250–300 g good-quality cooked ham, diced or cut into small strips
Vegetarian version
Simply omit the sausage.
For a little more depth, add sautéed onions or mushrooms between the potato layers.
How to make Slovak French Potatoes
1. Cook the potatoes in their skins
Wash the potatoes and cook them in salted water until almost tender.
Do not cook them completely soft. They should remain slightly firm as they will continue cooking in the oven.
Allow them to cool, peel and cut into slices approximately 4–5 mm thick.
Let the potatoes steam-dry for a few minutes before assembling the casserole. Less excess moisture means a better crust later.
2. Prepare the eggs and sausage
Hard-boil the eggs, cool and peel them, then cut into slices.
Slice the sausage into rounds or smaller pieces.
Briefly sauté the sausage with the finely chopped onion in a dry frying pan.
The aim is not to make the sausage crispy, but to release some of its fat and intensify its smoky flavour.
If using cooked ham, there is no need to fry it first.
3. Make the cream mixture
Combine the sour cream, cooking cream and two eggs.
Season lightly with salt and freshly ground black pepper.
Be careful with the salt, particularly when using smoked sausage and a well-seasoned cheese.
4. Layer the potato casserole
Grease a baking dish with butter.
Arrange a layer of sliced potatoes on the bottom and season lightly with salt and pepper.
Add some of the sliced hard-boiled eggs, sausage and onion.
Repeat the layers and finish with a layer of potatoes on top.
Do not press the layers together too firmly.
5. Add the cream mixture
Pour the cream and egg mixture evenly over the potatoes.
Gently shake the baking dish to help the cream work its way between the layers.
Do not add the cheese yet.
This small detail makes a considerable difference to the final crust.
6. Bake until creamy and set
Preheat the oven to 190°C / 375°F.
Bake for approximately 30–35 minutes, until the casserole is thoroughly heated and the creamy egg mixture begins to set.
7. Make the crispy cheese crust
Remove the dish from the oven and cover the surface with coarsely grated cheese.
For an even crispier topping, mix the cheese with 1–2 tablespoons of fine breadcrumbs.
Increase the oven temperature to 220°C / 425°F and bake uncovered for another 10–15 minutes, until the surface is deeply golden brown.
For extra colour and crunch, finish under the broiler/grill for 1–3 minutes.
Watch it carefully at this stage – the difference between beautifully browned cheese and burnt cheese can be surprisingly short.
8. Let the casserole rest
Allow the baked French potatoes to rest for 10–15 minutes before serving.
This gives the creamy filling time to set slightly and helps the individual layers hold together when portioned.
TGCC Tip: The secret to a crispy cheese crust
Excess moisture is the enemy of a crispy crust.
Let the cooked potatoes steam-dry before assembling the dish and, most importantly, add the cheese only towards the end of baking.
The first stage cooks the creamy interior and allows some moisture to evaporate. The second, hotter stage is all about browning the surface.
For extra crunch, add a small amount of breadcrumbs to the grated cheese.
And don’t be afraid of colour. Pale melted cheese is not yet a crispy crust. Look for a rich golden-brown surface with a few darker toasted spots.
Sausage, ham or vegetarian?
Smoked sausage produces the richest and most traditional version. Choose a good-quality sausage with plenty of meat and a pleasant paprika and smoky flavour.
Cooked ham makes a lighter version of French potatoes. Dice it or cut it into small strips and layer it in the same way as the sausage.
For vegetarian French potatoes, simply omit the meat. Potatoes, eggs, cream and baked cheese already provide plenty of flavour. Sautéed mushrooms are an excellent addition if you want more umami.
What to serve with Slovak French Potatoes
This creamy, rich potato casserole benefits from something fresh, crunchy and acidic on the side.
In Slovakia, the classic accompaniment is pickled cucumbers, just as in our photo.
Pickled vegetables, čalamáda – a Central European mixed vegetable pickle – or a simple green salad with a sharp vinaigrette also work beautifully.
The acidity cuts through the richness of the cream, cheese and sausage and makes the whole dish feel more balanced.
Are French Potatoes actually French?
Despite the name, Slovak French potatoes with eggs, sausage and cream are not a classic French recipe.
Potato gratins and baked potato dishes exist throughout Europe, but the version known in Slovakia as francúzske zemiaky belongs primarily to the tradition of Slovak and Central European home cooking.
The French have their gratins.
We have francúzske zemiaky.
And the French probably don’t even know about them.
Wine pairing
Grüner Veltliner – fresh acidity and subtle peppery notes work particularly well with cream, cheese and smoked sausage.
Riesling – choose a dry, lively Riesling to cut through the richness of the casserole.
For the lighter ham or vegetarian version, a fresh Sauvignon Blanc is another good option.
And there is no need to make this humble comfort food overly sophisticated – a well-chilled Slovak lager is a great match too.
