A savoury French pumpkin tart for something special and a great vegetarian option for Thanksgiving or Christmas.
Packed with roasted pumpkin, mushrooms, leeks and sage, it’s extra delicious with a rustic chestnut flour pastry base. For non-vegetarians add some leftover turkey. A taste of Autumn on a plate!
Savoury Pumpkin Tart
Every time Autumn arrives, the girls always ask for this tart. If entertaining, this also works well as mini pumpkin tartlets as a starter, just to be posh.
Why do we love it at this time of year? Because the combination of chestnut flour with pumpkin, mushrooms with some leek and sage is simply divine. Trust me, it’s totally worth the effort to make the pastry.
Somehow the lush, smooth taste of the chestnut flour pastry base fools us into thinking that there’s bacon or chicken in it. However, it’s vegetarian.
A Vegetarian Alternative for Christmas or Thanksgiving
Which means these pumpkin and mushroom tarts are perfect as a vegetarian no-turkey alternative for Thanksgiving or Christmas – or just a family treat to fall for! It’s also a versatile recipe: often I throw in the mushrooms and leek, topping it with some walnuts.
For non-vegetarians, if you want to add leftover turkey, it’s perfect together too.
Go Nuts with Pumpkin Tart
For this pumpkin tart, nuts go so well with pumpkin and mushrooms so are lovely when thrown on top before baking in the oven.
As you can see from the photos below, it’s also delicious topped with pecan nuts if you don’t like mushrooms. Alternatively add walnuts for that extra seasonal crunch! Add a few pre-cooked chestnuts to add that extra chestnut flavour, so popular in French supermarkets, sold as either vaccum-packed or in jars.

What is Potimarron in English?
French potimarron is so popular in France, perhaps even more so than regular pumpkin (potiron), sold by the slice at our local markets. Known more widely as Chestnut Pumpkin, Japanese Red kuri squash or red Hokkaido, the potimarron is best for this tart recipe. That’s because it’s less watery than regular pumpkin or butternut and it even tastes of chestnut – hence the part, ‘marron’ in the French name, which means chestnut. There’s no need to peel off the skin, either, as it’s edible.
If you can’t find potimarron, use regular pumpkin or butternut squash. As they give off more liquid, I would recommend blind-baking the pastry first for an extra 10 minutes, covered in parchment and baking beans.
Homemade Tart Pastry with Chestnut Flour
Chestnut flour is easily available in health food stores and in the organic healthy sections of many supermarkets in France. If you haven’t tried it yet, I urge you to do so. It’s one of the staple ingredients in Corsican cooking and popular in France. It’s also so powerful and rustic in flavour – that’s why I mix it with plain (all-purpose) flour.
Please don’t be put off by making the pastry. This pastry is a pleasure to work with if you follow this recipe to the letter, using measurements in grams or ounces with a digital kitchen scale (find out why measuring by weight rather than volume by cups makes baking life easier).
It’s totally worth it.
What Wine to Match with Savoury Pumpkin Tart?
The flavours of chestnut, pumpkin & mushroom in a tart or as mini tartlets match well with a light and fruity red wine.
What’s more, in Autumn, France goes slightly crazy over the basic Beaujolais and Beaujolais Nouveau the 3rd Thursday in November (that’s how I met my Frenchman, but that’s another story!). As our student days are over, we prefer the more sophisticated medium bodied Beaujolais Crus (e.g. Morgon, Brouilly, Julienas) – excellent value for money, in my humble opinion, compared with their expensive neighbours up the road in Bourgogne.
A light Loire red is also a great match with the tart – such as Chinon or Saumur reds.
Savoury Pumpkin Tart Recipe
Makes one large tart (28cm diameter) or 8 individual mini tartlets
Pumpkin Tart with Mushrooms and Chestnut Flour
Chestnut Flour Tart Base:
- 100 g (3.5oz) chestnut flour sifted
- 150 g (5.5oz) plain flour (all-purpose T55)
- 125 g (4.5oz) unsalted butter softened
- 1/2 tsp salt (fleur de sel)
- 4-5 tbsp water
Pumpkin Tart Filling:
- 300 g (11oz) pumpkin ( (or red kuri squash/potimarron) roughly chopped into small chunks
- 3 tbsp olive oil
- 1 leek, white part sliced finely
- 300 g (11oz) mushrooms (Parisian mushrooms, cremini) cut into big pieces
- 1 tsp sage leaves finely chopped
- 3 eggs organic
- 250 g (9oz) crème fraîche or half fat cream (I use 15% fat)
- good pinch ground nutmeg
- good pinch salt and pepper
- 2 tbsp freshly grated parmesan* (not the packaged grated stuff)
- Preheat the oven to 200°C/180°C fan (400°F/Gas 6).
For the chestnut flour pastry base:
- Mix all the ingredients together in a stand mixer or food processor and mix just until the dough forms a ball. Wrap in cling film and leave to rest in the fridge for 30 mins. Remove the dough from the fridge and leave to stand about 10 minutes, to make it easy to roll it out.
- Roll out the pastry on a lightly floured surface. Then, roll the pastry around the rolling pin to transfer it to a 28cm tart tin.
- Press the pastry well into the sides. Roll over the top of the tin to clean up any rough edges. Chill in the fridge for 30 minutes (this is important so the sides won't fall during baking later).
- If making a large tart, blind bake for 15 minutes covered in parchment and baking beans. No need for tartlets.
For the filling:
- If using a hard pumpkin like potimarron/Red Kuri squash, roast whole in the oven for 15 minutes. This will make it easier to cut into small chunks (no need to cut off the skin, it's edible). Let cool slightly to spoon out the seeds.Place the chopped pumpkin with 2 tbsp of the olive oil and chopped sage in a roasting tin. Roast in the oven for 20 minutes.
- Meanwhile, over medium heat, dry fry the mushrooms: there’s no need to add any oil. Wait until the mushrooms give off their liquid then transfer to a plate. Set aside to cool slightly. In the same pan, add the remaining olive oil and gently fry the sliced leek until translucent but not brown.
- In a bowl, whisk together the eggs, crème fraîche, nutmeg, grated cheese and season to taste.
- Sprinkle the roasted pumpkin and sage over the tart base, top with the leek and mushrooms and pour over the creamy egg mix. Bake in the oven for about 30 minutes.
