Makes one 9-inch quiche; serves 6 to 8
Ingredients
- 2 tbsp extra-virgin olive oil
 - 2 1/2 cups thin sliced yellow onions
 - 3/4 cup heavy cream
 - 3/4 cup whole milk
 - 3 large eggs
 - 1/2 tsp kosher salt
 - 1/4 tsp freshly ground black pepper
 - 1 1/4 cups grated provolone
 - One 9-inch Pie Crust, pre-baked
 
Directions
- Preheat oven to 350°F. Heat the oil in a sauté pan over medium heat. Add the onions and sauté stirring frequently, until golden and very soft (caramelized), about 35 minutes. Remove from the heat and reserve.
 - In a medium bowl, whisk together the cream, milk, eggs, salt, and pepper. Stir in the prepared onions and 1 cup of the cheese. Pour the egg mixture evenly into the pie crust. Sprinkle the remaining cheese evenly over the top of the quiche.
 - Set the quiche pan on a baking sheet and return the quiche to the oven. Bake until a knife blade inserted in the center comes out clean, 40 to 45 minutes.
 - Serve the quiche hot or at room temperature. The quiche can be cooled, wrapped, and stored in the refrigerator for up to 2 days. Reheat in a 325 F until hot, about 15 minutes.
