Make the Crust

  1. Gather the ingredients.

  2. Preheat the oven to 350 F. Place a baking tray in the oven.

  3. Using the pastry, line the base and sides of a 10-inch tart pan with a removable bottom. Gently press the pastry up against the sides, making sure there are no air bubbles. Trim to fit and prick the base with a fork. Place in the freezer for 15 minutes or until firm.

  4. Line the pastry with foil and add baking beads or uncooked rice to blind bake.

What Is the Difference Between a Quiche and a Frittata?

Although they are both egg-based dishes that are normally made to be a round shape, quiche and frittatas do have some significant differences. First, a quiche has a crust while a frittata does not. Second, there is more dairy in a quiche than in a frittata—in fact, many frittata recipes don't have any dairy at all. And finally, these brunch recipes differ in the way they are cooked; a quiche is fully baked in the oven and a frittata is cooked on the stovetop and often finished in the oven.
