For the Filling

- Cooked chestnuts – the star ingredient, adding a warm, nutty flavor and creamy texture to the tart.
- Heavy cream – creates a rich, luscious base that binds the filling ingredients together.
- Eggs – for a silky custard that sets the tart filling with a delicate finish.
- Garlic – finely minced to add a subtle punch without overpowering the other flavors.

How to Make Chestnut & Leek Tart
For the Crust:
- Combine the all-purpose flour, salt, and cold butter cubes in a food processor; pulse until mixture looks like coarse sand, ensuring bits of butter remain visible.
- Add the ice water one teaspoon at a time while pulsing, stopping when the dough clumps together but isn’t sticky to the touch.
- Chill the dough tightly wrapped in plastic wrap for at least 30 minutes, firming up the butter and preventing shrinkage during baking.
- Roll the chilled dough on a lightly floured surface to about 1/8-inch thickness, then gently transfer and press into a 9-inch tart pan.
- Blind-bake the crust at 375°F for 15 minutes using parchment and pie weights; remove weights, then bake another 5 minutes until edges turn light golden.
For the Filling:
- Sauté the sliced leeks and minced garlic in a tablespoon of butter over medium heat until soft, fragrant, and lightly golden, about 5 minutes.
- Stir together chopped chestnuts, heavy cream, eggs, fresh thyme, salt, and pepper in a bowl until ingredients are just combined.
- Pour the chestnut and leek filling into the warm tart crust, using a spatula to smooth the surface for even baking and a neat finish.
- Bake the tart at 350°F for 25 to 30 minutes, until the filling is just set and turns a delicate golden brown around the edges.
- Cool the tart on a wire rack for at least 10 minutes before slicing, allowing the creamy custard to firm up for clean, beautiful slices.
Optional: Sprinkle chopped parsley or drizzle aged balsamic glaze before serving.

How to Store and Freeze Chestnut & Leek Tart
Fridge: Store any leftover Chestnut & Leek Tart tightly covered in plastic wrap or in an airtight container for up to 3 days, ensuring it retains its creamy texture.
Freezer: For longer storage, freeze unbaked tart before pouring in the filling. Wrap it well in plastic and then foil. It can be frozen for up to 2 months; bake directly from frozen.
Reheating: To reheat baked tart, place it in a preheated oven at 350°F for 15–20 minutes. This refreshes the flaky crust while warming the filling.
Make-Ahead Tip: Prepare and refrigerate the filling a day in advance for a quick assembly and baking on the day of serving.
Expert Tips for Chestnut & Leek Tart
- Keep butter cold: Always use cold unsalted butter and chill your dough well to achieve that flaky, tender crust everyone loves in a Chestnut & Leek Tart.
- Don’t overmix dough: Pulse just until the mixture resembles coarse sand with visible butter pieces to avoid a tough crust.
- Sauté leeks gently: Cook leeks slowly over medium heat to bring out their natural sweetness without browning or burning.
- Blind-bake thoroughly: Use pie weights and bake the crust until lightly golden to prevent a soggy bottom once the filling is added.
- Check custard set: Bake the tart until the filling is just set—slight jiggle is okay; it firm up as it cools for perfect texture.
- Season thoughtfully: Taste your filling mixture before baking to balance salt, pepper, and thyme flavors, ensuring the chestnut shines through.

Chestnut & Leek Tart Recipe FAQs
How do I know if my leeks are fresh and ready for the tart?
Fresh leeks should feel firm with bright, green leaves and clean white stalks. Avoid any with dark spots all over or slimy textures—those are signs they’re past their prime. I recommend choosing medium-sized leeks for a perfect balance of sweetness and earthiness.
What’s the best way to store leftover Chestnut & Leek Tart?
Absolutely store leftovers in an airtight container or tightly wrapped with plastic wrap in the fridge. It will keep beautifully for 3 to 4 days. Before sealing, make sure the tart has cooled completely to avoid sogginess. This way, you can enjoy second helpings that stay just as tasty as day one!
Can I freeze the tart, and if so, how should I do it?
Very! The best method is to freeze the tart crust before adding the filling. After rolling out and placing it in the tart pan, wrap it tightly in plastic wrap and then foil to prevent freezer burn. Freeze for up to 2 months. When you want to bake, add the filling right on top of the frozen crust and bake as directed, adding a few extra minutes to cooking time to ensure it’s cooked through.
What should I do if my tart crust turns out tough instead of flaky?
Tough crust usually means the butter melted too much or the dough was overworked. Next time, keep butter as cold as possible and handle the dough gently, pulsing just until combined. Also, chill the dough well before rolling—this helps create those beautiful, flaky layers everyone loves in a Chestnut & Leek Tart!
Is this tart safe for pets or those with nut allergies?
This tart features cooked chestnuts, which are tree nuts. It’s best to avoid serving it to pets or people with nut allergies to prevent any risk. If you’d like a similar savory tart without nuts, consider swapping chestnuts for mushrooms or roasted squash for that cozy, hearty vibe.
