Ingredients
Scale
For the Dough
- 1 cup all-purpose flour
- 1/2 cup unsalted butter, chilled and cubed
- 1/4 cup cold water
- Pinch of salt
For the Filling
- 2 medium yellow onions, sliced
- 1 medium Granny Smith apple, diced
- 1 cup shredded aged cheddar cheese
- 2 tablespoons unsalted butter (for sautéing)
- Salt and pepper to taste
For the Custard
- 2 large eggs
- 1/2 cup heavy cream
Instructions
- Prepare the Dough: In a mixing bowl, combine the all-purpose flour and a pinch of salt. Cut in the chilled, cubed unsalted butter using a pastry cutter or fingers until the mixture is crumbly. Gradually add cold water, a tablespoon at a time, mixing until the dough comes together.
- Chill the Dough: Shape the dough into a disk, wrap it tightly in plastic wrap, and refrigerate for at least 30 minutes to firm up.
- Caramelize the Onions: In a skillet over medium heat, melt 2 tablespoons of unsalted butter. Add the sliced yellow onions and cook slowly, stirring occasionally, until they are soft and golden brown, about 20 minutes.
- Add the Apples: Stir the diced Granny Smith apple into the caramelized onions. Season with salt and pepper to taste, and cook for an additional 5 minutes until the apples soften slightly.
- Assemble the Tart: Preheat your oven to 375°F (190°C). Roll out the chilled dough on a floured surface and press it evenly into a tart pan. Pour the onion and apple mixture into the crust, then sprinkle the shredded aged cheddar cheese evenly over the top.
- Prepare and Pour Custard: In a bowl, whisk together the eggs and heavy cream until smooth. Pour this custard mixture over the filling in the tart shell, allowing it to settle evenly.
- Bake the Tart: Place the tart pan on the middle rack of the preheated oven and bake for 30-35 minutes. Bake until the crust is golden brown and the custard is set. Remove from the oven and allow to cool slightly before serving.
Notes
- This tart can be served warm or at room temperature.
- For added flavor, try incorporating fresh thyme or rosemary into the filling.
- Use aged cheddar for a sharper taste that complements the sweetness of the onions and apples.
- Ensure the dough is well chilled before baking to prevent shrinking.
- You can prepare the dough and filling a day ahead to save time on the day of baking.
