A quiche inspired by the legendary bakeries of France is pretty much perfect for every meal, and is ideal for entertaining because you can make it ahead. This one’s filled with fan faves like cheddar and Parmesan, crispy bacon, caramelized onion, tangy ranch spice, and earthy spinach, a llbaked in a tender, flaky crust. No worries if you want to skip the crimping—this quiche is just as tasty with craggy edges for a more rustic feel (trés chic!).
