Potato Bake with Root Vegetables and Goat Cheese Recipe
This is a Polish take on French gratin – thinly sliced potatoes, carrot, parsley root and leek baked in cream with herbs. The vegetables soften in a creamy sauce, while the goat cheese on top adds a slightly tangy, bold note and a golden crust. The recipe uses simple ingredients but is technically refined, so the bake cooks evenly and slices cleanly.
This is a variation on French gratin dauphinois, but with typically Polish root vegetables and goat cheese instead of classic Gruyère. It combines a bistro feel with ingredients that are easy to find at a local market.
Instead of a plain potato gratin, the sweetness of carrot and parsley root here balances the tanginess of goat cheese., The bake is creamy but not bland, and works well as a main dish, not just a side., It bridges French-style comfort food with familiar Polish vegetables.
Why this version works
- Thin, even 2–3 mm slices ensure all the vegetables soften in the same amount of time.
- Leek adds sweetness and juiciness, so the bake does not dry out despite the long baking time.
- Placing the goat cheese on top keeps it from overpowering the flavour and prevents the sauce from becoming too heavy.
- Baking first covered and then uncovered softens the vegetables and nicely browns the cheese.
Chef's tips
If you are slicing by hand, compare the thickness of the slices every few minutes – a few much thicker pieces can prevent the whole dish from cooking through., If after 30 minutes of baking the fork still meets a lot of resistance in the centre, cover with foil again and bake until you feel a clear softening., Taste the sauce before seasoning – thyme is easy to overdo and can overpower the delicate aroma of goat cheese.
How to serve
Serve with a simple salad and vinaigrette based on French mustard and wine vinegar to refresh the creamy flavour., As a side dish it pairs best with roast chicken or pork loin, which do not compete with the aroma of goat cheese., For a more elegant dinner, serve in small portions alongside roasted beetroot or fish.
Watch out for
- Slices of potato that are too thick will stay hard even when the top is browned.
- Too much cream will make the centre watery instead of creamy.
- If the cheese browns too quickly, move the dish to a lower rack or cover it loosely with foil.
- If you cut the bake immediately after taking it out of the oven, it will fall apart on the plate.
Substitutions
- You can replace goat cheese with feta or soft blue cheese if you like a more intense flavour.
- You can swap 30% cream for 18% cooking cream, adding a tablespoon of butter for extra creaminess.
- Replace the leek with thinly sliced onion or shallot, sautéed in butter beforehand.
- Swap thyme for rosemary or marjoram, using it more sparingly.
Ingredients
- potatoes peeled - 600 g
- carrot medium - 2 piece
- parsley root root - 1 piece
- leek white part - 0.5 piece
- goat cheese log or soft - 120 g
- cream 30% or 18% - 250 ml
- garlic finely chopped - 2 cloves
- butter for the dish - 15 g
- thyme dried herb - 1 teaspoon
- salt to taste
- black pepper to taste
Preparation
- Preheat the oven to 190°C, top and bottom heat. Thoroughly butter a baking dish, including the sides – the layer of fat should be clearly visible but not in clumps.
- Peel the potatoes, carrot and parsley root and slice into 2–3 mm slices. Check a few slices on a plate – if they are clearly thicker than a coin, cut them thinner, otherwise the centre will stay hard.
- Cut the leek lengthwise, rinse very thoroughly between the layers, dry on a towel and slice into thin half-moons. If you see droplets of water after slicing, dry them again so the bake does not turn watery.
- In a bowl mix the cream with the pressed garlic, thyme, salt and pepper. Taste the sauce – it should be slightly oversalted and clearly herby, because the flavour will be spread across all the layers.
- Arrange a layer of potatoes on the bottom of the dish, slightly overlapping like roof tiles so there are no gaps. Spread some of the carrot, parsley root and leek on top to form an even, thin layer.
- Lightly season the vegetables with salt and pepper and drizzle with a thin layer of cream. Repeat the layers of potatoes and vegetables, gently pressing each one down with your hand – the surface should be even and compact.
- Arrange a final layer of potatoes on top and pour over the remaining cream so the top slices are moistened but the sauce does not stand above the vegetables. Cover the dish tightly with aluminium foil, shiny side facing in.
- Bake for 30 minutes covered, until a fork goes into the vegetables with noticeable but not great resistance and small bubbles of sauce appear around the edges. If the centre is still hard, bake for another 5–10 minutes under foil.
- Remove the foil. Slice or crumble the goat cheese and distribute it evenly over the top; for a more intense flavour, tuck some of the cheese between the top potato slices, gently prying them apart.
- Bake for 15 minutes uncovered, until the cheese is lightly golden and the edges are starting to brown. After removing from the oven, let the bake stand for 10–15 minutes – the sauce will thicken and the portions will hold their shape when cut.
Storage
Store tightly covered in the fridge for up to 3 days – the sauce will thicken further and the edges will become more set. Reheat covered at 170°C or in a pan with a spoonful of cream; the cheese will be less creamy but the flavour will stay concentrated.
I most often make this bake on Saturday after coming back from the market with a bag of small potatoes and carrots with their tops from the same farmer. I always save a piece for Sunday – fried in butter in a pan it develops a crispy, lightly caramelised crust.
