Ingredients with Measurements:
- 1 pre-made pie crust
- 2 tablespoons unsalted butter
- 2 large onions, thinly sliced
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- 1/2 teaspoon garlic powder
- 4 eggs
- 1 cup heavy cream
- 1 cup grated Abertam cheese
Special equipment needed:
- 9-inch tart pan
- Rolling pin
- Parchment paper
- Pie weights or dried beans
Step-by-step instructions:
1. Preheat the oven to 375°F.
2. Roll out the pie crust on a lightly floured surface to fit the tart pan. Transfer the crust to the pan and press it into the bottom and sides. Trim the edges and prick the bottom with a fork.
3. Line the crust with parchment paper and fill it with pie weights or dried beans. Bake for 10 minutes.
4. Remove the parchment paper and weights and bake for an additional 5 minutes, until the crust is lightly golden. Set aside to cool.
5. In a large skillet, melt the butter over medium heat. Add the onions, salt, pepper, thyme, rosemary, and garlic powder. Cook, stirring occasionally, for 15-20 minutes, until the onions are caramelized and golden brown.
6. In a medium bowl, whisk together the eggs and heavy cream. Stir in the grated Abertam cheese.
7. Spread the caramelized onions evenly over the bottom of the tart crust. Pour the egg and cheese mixture over the onions.
8. Bake for 30-35 minutes, until the filling is set and the top is golden brown.
9. Let the tart cool for 10 minutes before slicing and serving.
