Easy Quiche Recipe With Bacon and Spinach (Basic Quiche Recipe) from The Food Charlatan. Quiche is not a breakfast casserole baked in a pie shell, oh no. It is a creamy concoction that is more custard like, with plenty of cheese to boot. This is my favorite basic spinach quiche recipe because it is easy, incredibly flavorful, and hello, bacon. I will show you step-by-step how to make quiche for the perfect brunch! This is the perfect breakfast for Christmas, Easter, Thanksgiving, or any holiday!
