Overnight French Toast Casserole

Liz’s mother and both brothers were diagnosed with celiac disease and her mom made everything from scratch in a gluten-free kitchen. When her first child tested positive for celiac disease, Liz pulled from her mom’s inspiration and began running a gluten-free household herself. She has witnessed firsthand how following a gluten-free diet reduces skin irritation, inflammation, and pain. With her website, Gluten-Free Mom Colorado, she is on a mission to help people discover amazing gluten-free options and to see that a celiac or gluten intolerance diagnosis is not a curse, but can actually be delicious and make you feel great! We’re thrilled to be a part of her mission.
