With its flaky crust and rich filling, it's a perfect centerpiece for any gathering or a cozy dinner at home.

Ingredients
- 1 pre-made pie crust or tart shell
- 2 cups mushrooms, sliced (such as cremini or button)
- 1 cup walnuts, chopped and toasted
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 2 tablespoons fresh thyme leaves, chopped
- 3 large eggs
- 1 cup heavy cream or crème fraîche
- 1 teaspoon salt, adjust to taste
- 1/2 teaspoon black pepper
- 1/4 cup grated Parmesan cheese (optional)
- Olive oil for sautéing
Instructions
- Prepare the Crust: Preheat the oven to 375°F (190°C). Roll out the pie crust and fit it into a tart pan. Prick the bottom with a fork and bake for 10 minutes until lightly golden. Remove from oven and set aside.
- Sauté the Vegetables: In a large skillet, heat olive oil over medium heat. Add chopped onions and garlic, sauté until translucent. Add sliced mushrooms and cook until they release their moisture and become golden brown. Stir in the toasted walnuts and fresh thyme, and season with salt and pepper. Remove from heat.
- Make the Filling: In a bowl, whisk together the eggs and heavy cream. Stir in the sautéed mushroom mixture and Parmesan cheese if using.
- Assemble the Tart: Pour the filling into the pre-baked tart shell, spreading it evenly. Bake in the preheated oven for 25-30 minutes, or until the filling is set and golden on top.
- Cool and Serve: Allow the tart to cool slightly before slicing. Serve warm or at room temperature, garnished with additional thyme if desired.
Cook’s tips
- Toast the walnuts in a dry skillet over medium heat until fragrant, about 5 minutes, to enhance their nutty flavor.
- Use a mix of mushroom varieties, such as cremini, shiitake, and oyster, for a more complex taste and texture.
- Blind-bake the crust fully before adding the filling to prevent a soggy bottom.
- Let the tart rest for 10 minutes after baking before slicing; this allows the filling to set for cleaner cuts.
Substitutions
- Use puff pastry instead of pie crust for a flakier, more buttery texture.
- Substitute heavy cream with half-and-half or a mix of milk and melted butter for a lighter filling.
- Replace Parmesan with Gruyère, cheddar, or a dairy-free alternative like nutritional yeast for a different flavor profile.
- If fresh thyme is unavailable, use 1 teaspoon dried thyme in place of the 2 tablespoons fresh.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F (175°C) oven for 10–15 minutes to restore the crust's crispness.
Frequently asked questions
Can I make this tart ahead of time?
Yes, you can assemble and bake the tart, then cool it completely and refrigerate. Reheat it in the oven before serving to restore the texture.
Can I use other nuts instead of walnuts?
Absolutely! Pecans, almonds, or hazelnuts work well in this recipe. Just make sure to toast them first to bring out their flavor.
How do I prevent a soggy crust?
Blind-bake the crust for 10 minutes before adding the filling, and ensure the mushrooms are cooked until their moisture evaporates before mixing with the cream.
Can I freeze the baked tart?
Yes, wrap the cooled tart tightly in plastic wrap and foil, then freeze for up to 2 months. Reheat from frozen in a 350°F oven until warmed through.
