This gluten-free quiche lorraine with leeks is perfect for Mother’s Day brunch! The crisp cassava flour crust and custardy filling studded with leeks and bacon are both total crowd pleasers.
Mother’s Day is right around the corner, and if your mom is anything like mine, she would love this quiche. I’ve been working on it for weeks, playing with the proportions to make a crisp but sturdy crust with my new favorite grain-free flour, Otto’s cassava flour, and balancing the flavorings of the filling so that they’re just right. After more tries than I care to count, I’ve finally nailed it. This gluten-free quiche lorraine is good enough for your mother, skeptics who raise their eyebrows at the thought of grain-free pastries, and just about anyone else. Don’t tell your gluten-eating family members and I bet they won’t know there’s no wheat in here.
Quiche is a bit of a process, so setting aside my recent burst of quiche-testing mania, I don’t make it often. A frittata is quicker and easier and does just fine for a regular meal, but when the occasion is special or you want to treat yourself, a quiche is 100% worth it.
Despite the many recipes that try to bill a frittata as a crustless quiche, the absence of crust is not the only difference between the two. The fillings of quiches and frittatas, even when made with similar ingredients in similar proportions, are totally different in texture. In addition to the quiche crust being delicious and satisfyingly toothsome in its own right, it plays a vital role in ensuring that the filling is delicate, light, and custardy instead of chewy and overcooked. The crust shields the egg and cream mixture from getting too much direct heat, which allows it to bake into an impossibly smooth and irresistible sensation that’s worlds better than an omelette or frittata.
