Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
500g (1 pound) waxy salad potatoes
3 large leeks, trimmed
A small bunch of fresh dill
A few sprigs of fresh mint
3 cloves garlic
1 tbsp unsalted butter plus extra for greasing the dish
Salt and black pepper, to taste
6 tbsp crème fraiche
200g (7 oz) grated hard cheese such as Cheddar, Comte, or Gruyere
100ml (1/3 cup) dry white wine
30g (2 tbsp) grated Parmesan
Directions
Boil the potatoes in salted water until tender. Drain and let them cool slightly.
Slice the leeks into 2cm thick discs. Finely chop the dill and mint leaves, and peel and finely chop the garlic.
Melt 1 tablespoon of butter in a pan over medium-high heat. Add the leeks and cook until they start to brown and soften, about 5 minutes. Stir in the garlic, dill, and mint, and season well with salt and pepper.
Slice the cooled potatoes into medium-thick slices.
Preheat the oven to 200°C (400°F, gas mark 6). Butter a large gratin dish.
Layer the potatoes at the bottom of the dish. Season with salt and pepper, then spread 2 tablespoons of crème fraiche over the potatoes and sprinkle a quarter of the hard cheese on top. Add half of the cooked leeks. Repeat with another layer of potatoes, seasoning, crème fraiche, cheese, and the remaining leeks. Top with the remaining potatoes and cheese.
Pour the white wine evenly over the dish and sprinkle with half the Parmesan. The bake can be refrigerated at this point if preparing ahead of time.
Bake for 25–30 minutes until the top is golden and bubbling. Allow to rest for 5 minutes before serving, then sprinkle with the remaining Parmesan.
Add mushrooms: Sauté 150g of mushrooms with the leeks for an earthy twist.
Vegan version: Use a plant-based crème fraiche and vegan cheese alternative.
Herb swap: Replace dill and mint with thyme or parsley for a different flavor profile.
Spicy touch: Add a pinch of smoked paprika or chili flakes to the leek mixture.
Single-layer bake: Mix all ingredients together in one layer for a quicker assembly.
Storage/Reheating
Storage: Keep leftovers in an airtight container in the refrigerator for up to 3 days.
Freezing: Bake fully and allow to cool, then freeze in a sealed container for up to 2 months.
Reheating: Reheat in a 180°C (350°F) oven for 15–20 minutes until warmed through. Microwaving is possible but may make the top less crispy.
