The easy fix is to go crustless: a crustless quiche or a frittata is essentially the same egg custard without the pastry, and is naturally gluten-free (just confirm no flour was added to the filling). You can also use a gluten-free crust.
For a safe option, make or order a crustless quiche/frittata, or use a certified gluten-free pie crust; avoid standard bakery and frozen quiche, which are wheat-based.

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten — a protein found in wheat, barley, and rye — triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces — such as shared cutting boards, toasters, fryers, or utensils — rendering otherwise safe food dangerous for people with celiac disease.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten — stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
