Key Ingredients
- All-purpose flour — gives structure to the crust; use room temperature for best results.
- Unsalted butter (cold and cubed) — ensures flakiness in the tart crust; must be cold before using.
- Ice water — keeps the dough cool, preventing gluten development that can make the crust tough.
- Olive oil — provides a mild flavor to the filling; use high-quality for best taste.
- Onions (thinly sliced) — add depth and sweetness to the tart; ensure they are finely sliced for even cooking.
- Mushrooms (sliced, such as cremini or button) — provide earthy flavors and moisture content; slice them thinly too for consistent cooking.
- Garlic (minced) — adds a subtle pungency that complements the vegetables.
- Thyme — provides aromatic depth and herby notes; dried works if fresh is not available.
- Heavy cream — gives richness to the filling; use full-fat for best results.
- Eggs — bind the ingredients together, ensuring a smooth texture in the tart.
- Cheese (grated Gruyère or Parmesan) — adds a sharp flavor and melts beautifully into the filling.
Step-by-Step Instructions
- Prepare the Tart Crust:
– In a large mixing bowl, combine 1 1/4 cups of all-purpose flour and 1/2 teaspoon salt.
– Add 1/2 cup of cold cubed unsalted butter to the flour mixture.
– Using a pastry blender or your fingers, cut the butter into the flour until the mixture resembles coarse crumbs.
- Forming the Dough:
– Gradually add 3–4 tablespoons of ice water to the flour-butter mixture, mixing just until the dough comes together in a ball.
– Wrap the dough in plastic wrap and refrigerate for at least 15 minutes before rolling out.
- Rolling Out the Crust:
– On a floured surface, roll the chilled dough into a circle about 1/4-inch thick.
– Carefully transfer the rolled-out dough to a tart pan with a removable bottom; trim any excess crust around the edges.
- Blind Bake the Crust:
– Line the crust with parchment paper and fill it with pie weights or dried beans.
– Preheat your oven to 350°F (180°C).
– Blind bake for about 15 minutes, then remove the parchment and weights; continue baking for another 5 minutes until lightly golden.
- Cooking the Filling Ingredients:
– In a large skillet over medium heat, add 2 tablespoons of olive oil.
– Add 2 sliced onions and 8 ounces of mushrooms to the skillet; cook for about 10 minutes or until the vegetables are tender and caramelized.
– Stir in 2 minced cloves of garlic and 1 teaspoon of fresh thyme (or dried); sauté for an additional minute.
- Assembling the Tart:
– Remove the tart crust from the oven; preheat your broiler.
– Pour the cooked vegetable mixture into the cooled tart shell, spreading it evenly.
– Beat 2 large eggs in a small bowl and gently stir them with 1/2 cup of heavy cream. Pour this mixture over the vegetables.
- Baking the Tart:
– Sprinkle 1/2 cup of grated cheese (Gruyère or Parmesan) over the top.
– Place the tart under your broiler for about 5 minutes, watching carefully so that it does not burn; remove when the cheese is golden and bubbly.
- Serving:
– Allow the tart to cool slightly before slicing and serving. It can be enjoyed warm or at room temperature with a side salad.
