In the Loire Valley, mushrooms have long been cultivated in old troglodyte caves, where the cool, damp air creates the perfect growing conditions. This savory tart combines those earthy mushrooms with another Loire Valley specialty: creamy goat cheese. It’s easy to make and perfect for lunch or a light dinner with a green salad.
Ingredients (serves 4)
- 1 sheet frozen puff pastry (thawed)
- 2 tablespoons olive oil
- 1 small yellow onion, thinly sliced
- 2 garlic cloves, minced
- 12 oz (340 g) fresh mushrooms (button or cremini), sliced
- 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
- Salt and freshly ground black pepper
- 4 oz (115 g) soft goat cheese (chèvre)
- 1 large egg, beaten (for brushing the pastry)
Instructions
- Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
Prepare the pastry:
- Lightly flour your countertop.
- Roll out the puff pastry into a rectangle or circle (whatever fits your baking sheet).
- Place it on the prepared sheet.
- Using a small knife, score a ½-inch border around the edge of the pastry (don’t cut all the way through). This will help the edges puff up as it bakes.
Cook the filling:
- Heat the olive oil in a large skillet over medium heat.
- Add the sliced onion and cook for about 5–6 minutes, stirring often, until it starts to soften and turn golden.
- Add the garlic, mushrooms, thyme, a pinch of salt, and some black pepper.
- Continue to cook for 8–10 minutes, stirring occasionally, until the mushrooms are soft, any liquid has evaporated, and everything smells delicious.
Assemble the tart:
- Spoon the mushroom mixture evenly over the puff pastry, keeping it inside the border.
- Crumble the goat cheese over the top.
Brush and bake:
- Use a pastry brush (or clean fingers) to brush the beaten egg around the border of the pastry.
- Bake for 20–25 minutes, or until the edges are golden brown and puffed up.
Serve:
- Let the tart cool for a few minutes before cutting it into slices
- Serve warm or at room temperature with a simple green salad.
Bon appétit !
