One of my all-time favorite Quiche Lorraine recipes is this one from Ina Garten, made with all-purpose flour, kosher salt, unsalted butter, ice water for the crust, yellow onion, bacon, fresh thyme leaves, shredded Gruyere, heavy cream, and large eggs for the filling. It needs around 4 hours and 15 minutes to complete, including chilling and cooling times. You can pair your Quiche Lorraine with sides such as a simple green salad, roasted vegetables, fresh fruit, or a bowl of soup.
