Lupin Free Gluten Free Pie Crust

A flaky, golden pie crust is the foundation of so many beloved desserts and savory dishes, and this one delivers that satisfying snap and tender bite without a trace of wheat or lupin flour. Lupin is increasingly common as a protein-boosting flour substitute in gluten-free baking blends, so store-bought crusts and mixes can be tricky territory — making your own from scratch is the cleanest way to stay safe. Here, white rice flour, tapioca starch, and potato starch team up to create a crust that's genuinely light and crisp rather than gummy or dense. The cold butter technique — cutting it in until you still have pea-sized pieces — is the same trick that makes traditional pastry so irresistibly flaky, and it works beautifully in this dough. A splash of apple cider vinegar and a cold egg help bind everything together and keep the texture tender, while xanthan gum gives the dough just enough elasticity to roll out without falling apart. Rolling it between two sheets of parchment makes the whole process far less stressful, and any cracks along the edges press back together easily. Whether you blind-bake it for a custard filling or load it straight up with fruit, this crust holds its shape and tastes like the real thing.
