Tarte aux Champignons (Mushroom Tart)

Tarte aux Champignons has a way of settling into the pace of the day. It’s not something you rush through—it happens when things slow down a little, when the kitchen feels quieter and there’s time to let ingredients do what they’re meant to do. The first sign is always the smell, mushrooms hitting a hot pan, releasing that deep, earthy aroma that fills the space almost immediately.

They take their time. At first there’s moisture, more than you expect, but it cooks off gradually, leaving something more concentrated behind. The color deepens, the texture changes, and what started out light becomes richer, almost meaty in a way that feels surprising every time. A bit of garlic, a touch of thyme, just enough to frame it without pulling focus.

The custard comes in gently, softening the edges without taking anything away. It moves through the mushrooms rather than over them, holding everything together while still letting each part stay present. Then there’s the crust, golden and buttery, giving just enough structure to support it all without making the dish feel heavy.

Once it’s baked, it settles into itself.

You slice into it without much thought, the filling just set, still soft, still warm. It doesn’t ask for attention—it holds it quietly. Earthy, balanced, a little indulgent but never overwhelming, the kind of dish that works its way through a meal without needing to be the center of it.

And before you realize it, you’ve gone back for another piece.

Prep Time1 hrCook Time1 hrTotal Time2 hrs

For the Pastry:
 1 1/4 cups all-purpose flour
 1/2 teaspoon salt
 1/2 cup (113g) cold unsalted butter, cubed
 3-4 tablespoons ice water
For the Filling:
 2 tablespoons olive oil
 1 lb (450g) mixed mushrooms (such as cremini, shiitake, and button), sliced
 2 garlic cloves, minced
 1 shallot, minced
 1 teaspoon fresh thyme leaves
 Salt and pepper to taste
 1/2 cup crème fraîche or heavy cream
 2 eggs
 1/2 cup grated Gruyère or Parmesan cheese

1

Prepare the Pastry: In a bowl, combine flour and salt. Add butter and mix until the mixture resembles coarse crumbs. Gradually add ice water until the dough comes together. Form into a disk, wrap in plastic, and chill for at least 1 hour.

2

Pre-bake the Crust: Preheat the oven to 375°F (190°C). Roll out the dough to fit a 9-inch tart pan. Press into the pan, trim the edges, and prick the bottom with a fork. Line with parchment and fill with pie weights. Bake for 15 minutes, remove weights and parchment, and bake for another 5 minutes.

3

Prepare the Filling: In a skillet, heat olive oil over medium heat. Sauté mushrooms, garlic, shallot, and thyme until mushrooms are browned and tender. Season with salt and pepper. Let cool.

4

Assemble the Tart: In a bowl, whisk together crème fraîche, eggs, and cheese. Stir in the mushroom mixture. Pour into the pre-baked crust.

5

Bake the Tart: Bake at 375°F (190°C) for 25-30 minutes or until the filling is set and the top is golden.

6

Serve: Garnish with fresh parsley. Serve warm or at room temperature.

Perfect Wine Pairing:

  • Chardonnay: A buttery Chardonnay with oak notes can complement the mushrooms’ earthy flavors and the tart’s richness.
  • Alternative: A Pinot Noir or Beaujolais offers a lighter, fruitier contrast to the savory tart, beautifully balancing the flavors.
