Two of my favorite conversations that happen around my new book The Homemade Flour Cookbook is when someone realizes that grinding flour at home isn’t just about making wheat flour for bread and that not all flour requires buying a grain mill. I find it really fun and exciting to play with grains, legumes, nuts, and seeds in unexpected ways, and this recipe for mini breakfast quiches with their easy flax crust is the perfect example.

Flaxseed meal is one of the easier items to grind at home; you can make it just by using a coffee grinder or high-powered blender (though I’ve found the seeds to be a bit small for the food processor to really break them down). Flax is also best milled in small batches and then used right away, as ground flaxseeds can go rancid rather quickly.

The crust of this quiche plays into the idea that flaxseed meal acts like a binding agent (think flax-egg), creating a cohesive crust with the help of an egg white. After baking, the crust is crisp and crunchy — a fun, gluten-free spin on the traditional quiche crust. These mini-quiche are perfect for parties and brunches, and the filling can be changed based on what you have on hand.

Recipe Notes

In recent years, quiche has made an appearance at every family holiday. It started out as a way to serve a substantial vegetarian main dish but has turned into a tradition. If I’m having people over for breakfast, quiche is my first go-to recipe. Using flaxseed meal instead of traditional piecrust is a fun way to add a bit of crunch to the quiches.

Because of the crisp nature of this crust, it’s easier to manage in the smaller servings. This quiche could be made in a 9-inch (23-cm) pie pan, but solid pieces that hold together may be hard to cut.
