Cuisine: French
Serves: 6 servings
Ingredients
- 1 sheet pie crust
 - 2 large potatoes, thinly sliced
 - 1 cup mushrooms, sliced
 - 1 large onion, thinly sliced
 - 200g brie cheese, sliced
 - 2 tablespoons olive oil
 - Salt and pepper to taste
 
Instructions
- Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper and set aside.
 - In a large skillet, heat olive oil over medium-low heat. Add thinly sliced onions and cook slowly, stirring occasionally, until they become deeply golden and caramelized, approximately 20-25 minutes. Season with a pinch of salt.
 - While onions are caramelizing, wash and thinly slice potatoes using a mandoline or sharp knife. Pat potato slices dry with paper towels to remove excess moisture.
 - In the same skillet used for onions, sauté sliced mushrooms over medium heat until they release their moisture and become lightly browned, about 5-7 minutes. Season with salt and pepper.
 - Unroll the pie crust and place it on the prepared baking sheet. Leave a 2-inch border around the edges for folding.
 - Layer the ingredients on the pie crust: first spread caramelized onions, then arrange potato slices in overlapping circles, sprinkle sautéed mushrooms, and top with sliced brie cheese.
 - Fold the edges of the pie crust inward, creating a rustic, free-form tart. Brush the exposed crust with olive oil for a golden finish.
 - Bake in the preheated oven for 35-40 minutes, or until the crust is golden brown and potatoes are tender.
 - Remove from oven and let cool for 10 minutes before slicing. Serve warm as a main course or appetizer.
 
Tips
- Moisture is the Enemy: Always pat your potato and mushroom slices dry to prevent a soggy crust. Use paper towels to remove excess liquid.
 - Caramelization is Key: Take your time with the onions—low and slow is the secret to achieving that deep, sweet golden color.
 - Slice Uniformly: Use a mandoline or sharp knife to ensure even potato slices for consistent cooking and a beautiful presentation.
 - Don't Overcrowd: Leave space between ingredients to allow for proper browning and crisp edges.
 - Room Temperature Brie: Let the cheese sit out for 15-20 minutes before using to ensure it melts more evenly.
 - Olive Oil Brush: A light brush of olive oil on the crust creates a beautiful golden sheen and adds extra flavor.
 - Resting Time Matters: Allow the tart to cool for 10 minutes after baking to let the cheese set and make slicing easier.
