Imagine a golden, flaky crust cradling a creamy, savory filling of tender white fish and sweet, mellow leeks. This Open-Faced White Fish and Leek Tart is a celebration of simple, high-quality ingredients. It is a versatile dish that works beautifully as a sophisticated lunch, a light dinner, or an impressive starter. The recipe comes from the renowned Russian magazine "Gastronom" and offers a perfect balance of textures and flavors. If you cannot find a suitable white fish, the recipe suggests substituting salmon, which adds a richer, oilier profile. The key is to use fresh, sustainable fish and to cook the leeks slowly until they are meltingly soft. This tart is a testament to the idea that the best cooking often requires just a few ingredients, each allowed to shine.
About This Tart
This open-faced tart, or "pirog," is a classic of Russian home baking, yet it shares DNA with French quiche and Italian torta salata. The filling is a simple mixture of poached white fish and sautéed leeks, bound together with a custard of eggs, cream, and Parmesan. The crust is a store-bought puff pastry or shortcrust, which keeps the preparation quick and accessible. The tart is baked until the top is golden and the filling is just set, then cooled slightly before serving. This dish is perfect for using up leftover fish or for showcasing a delicate fillet of cod, haddock, or pollock. The leeks provide a subtle oniony sweetness that complements the fish without overpowering it.

Ingredients
- 2 large leeks (white and light green parts only)
- 30 g unsalted butter
- Salt, to taste
- 400 g white fish fillets (cod, pollock, haddock, or salmon)
- Freshly ground black pepper, to taste
- 1 sheet puff pastry or shortcrust pastry (about 300 g)
- 3 large eggs
- 200 ml heavy cream (35% fat)
- 50 g grated Parmesan cheese
Step-by-Step Instructions
Step 1: Prepare the Leeks
Cut the leek stems in half lengthwise and rinse thoroughly under cold water to remove any sand. Thinly slice the leeks crosswise into half-moons. In a large skillet, melt the butter over medium heat. Add the sliced leeks and a pinch of salt. Cook, stirring occasionally, until the leeks are very soft and translucent, about 5 minutes. Do not let them brown. A non-toxic immersion blender is not needed here, but a good quality skillet helps ensure even cooking.
Step 2: Prepare the Fish
Cut the fish fillets into 1.5 cm cubes. Add the fish cubes to the pan with the cooked leeks. Season with a little more salt and a generous amount of freshly ground black pepper. Gently stir to combine, then remove from heat.
Step 3: Prepare the Pastry
Preheat your oven to 170°C (without convection, if possible). If using a commercial countertop convection oven, adjust temperature as needed. Roll out the pastry on a lightly floured surface to a circle about 30 cm in diameter. Transfer the pastry to a 26 cm tart or pie dish, letting the excess hang over the edges. Prick the bottom of the pastry all over with a fork. Spread the fish and leek mixture evenly over the pastry.
Step 4: Make the Custard
In a medium bowl, whisk together the eggs, heavy cream, a pinch of salt, and a few grinds of black pepper until smooth. Stir in the grated Parmesan cheese. For perfect consistency, you can use a planetary mixer, but hand whisking works perfectly.
Step 5: Assemble and Bake
Pour the custard over the fish and leek mixture, ensuring it spreads evenly. Place the tart in the lower third of the oven and bake for about 40 minutes, or until the filling is set and the pastry is golden brown and puffed. Remove from the oven and let the tart cool on a wire rack for at least 20 minutes. For best results, use a steam canner for preserving any leftovers, though this tart is best fresh.
Tips for the Perfect Tart
- Don’t skip cooling: Letting the tart rest allows the custard to set fully and makes slicing cleaner.
- Pastry handling: If using puff pastry, keep it cold until ready to use. Overhanging edges can be trimmed after baking for a neat finish.
- Fish substitutions: Smoked fish like haddock or trout can replace fresh white fish for a deeper flavor. A wheatgrass juicer won’t help here, but a good fishmonger will.
- Leek washing: Leeks can be gritty; slice them and swish in a bowl of water, then lift out leaving sand behind.
Variations to Explore
This recipe is easily adaptable. Swap the white fish for salmon as suggested, or use a mix of seafood like shrimp and scallops. Add a handful of fresh spinach or dill to the custard. For a vegetarian version, substitute the fish with roasted mushrooms or artichoke hearts. A touch of nutmeg in the custard adds warmth.

FAQ
Can I use frozen fish for this recipe?
Yes, but thaw it completely and pat dry before cubing to avoid excess moisture in the filling.
What type of pastry is best?
Puff pastry gives a light, flaky crust. Shortcrust pastry is also excellent, offering a sturdier base. A food processor for nut butter can be repurposed to make pastry dough quickly.
Can I make this tart ahead of time?
Yes, you can assemble it a few hours in advance and bake just before serving. It also reheats well in a non-toxic air fryer.
How should I store leftovers?
Store in an airtight container in the refrigerator for up to 3 days. Reheat in a low oven or microwave.
What side dishes pair well?
A simple green salad with lemon vinaigrette or steamed asparagus complements the richness of the tart.
Can I substitute the cream with milk?
Milk will make the custard less rich and may not set as firmly. For a lighter version, use half-and-half.
