I love quiches. They are a super versatile dish that can be served at brunch, lunch, or dinner, as an appetizer or main dish paired with a bowl of soup and a green salad. You can eat them hot, warm, or at room temperature… What can be better than that?

The Secret for a Flavorful Quiche Crust

Not only I do it with sweet Vidalia onions, that I sauté in butter until they caramelize while infusing them with the subtle flavor of fresh thyme. There is one more secret.

To add more complexity to my quiche crust, I let it cool down and cover the bottom with grated Parmesan cheese once the crust is baked. Then I add the sautéed onions to finally add the mixture of eggs, heavy cream, and more Parmesan. Trust me: the Parmesan addition brings the crust to the next level.

One more thing about the crust recipe: it’s made with the same pie or quiche dough that I’ve been using forever. I only adjusted the ingredient quantities, so there is no waste.

Vidalia onions are the sweetest, whitest onions ever. These beautiful pristine onions are hand cultivated and picked by around 100 registered growers. They only grow them in the low sulfur soils of 20 South Georgia counties. The mild winters of Southern Georgia contribute to the unique sweetness of the wonderful Vidalia crop.
