Ingredients
Dough
- 1 cup all-purpose flour
- 1/2 cup unsalted butter (chilled, cubed)
- 1/4 cup cold water
- Salt to taste
Filling
- 2 medium yellow onions (sliced)
- 1 medium Granny Smith apple (diced)
- 1 cup shredded aged cheddar cheese
- 2 large eggs
- 1/2 cup heavy cream
- Salt and pepper to taste
Instructions
- Prepare the Dough: In a bowl, mix the all-purpose flour with a pinch of salt. Cut in the chilled, cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Gradually add the cold water, a tablespoon at a time, mixing until a dough forms.
- Chill the Dough: Shape the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes to firm up and rest, ensuring a tender crust.
- Caramelize Onions: Heat a skillet over medium heat and melt some butter. Add the sliced yellow onions and cook, stirring occasionally, until they become golden brown and caramelized, approximately 20 minutes. This process enhances their sweetness and depth of flavor.
- Add Apples: Stir the diced Granny Smith apples into the caramelized onions. Season with salt and pepper, then cook for an additional 5 minutes to slightly soften the apples and meld the flavors.
- Assemble the Tart: Preheat the oven to 375°F (190°C). Roll out the chilled dough on a lightly floured surface to fit a tart pan. Press the dough evenly into the pan, trimming any excess. Pour the onion and apple mixture into the crust. In a separate bowl, whisk together the eggs and heavy cream, then pour this mixture over the filling. Sprinkle the shredded aged cheddar cheese evenly on top.
- Bake: Place the tart in the preheated oven and bake for 30-35 minutes, or until the crust is golden brown and the filling is set. Remove from the oven and allow to cool slightly before serving.
Notes
- Using chilled butter and cold water is key for a flaky tart crust.
- For extra flavor, you can add a teaspoon of fresh thyme or rosemary to the caramelized onion and apple mix.
- Serve warm or at room temperature with a green salad for a complete meal.
- Leftovers can be stored in the refrigerator for up to 3 days.
