The Story Behind This Gluten Free Casserole Recipe
Hi! I’m Abby Pinkmann, founder of EAT WELL WELL and a chef just outside Austin, Texas.
Some of my favorite childhood memories happened around a casserole dish sitting in the middle of our kitchen table. My mom had a gift for turning simple ingredients into meals that brought everyone together. She could take leftover chicken, rice from the night before, a handful of vegetables, and a little cheese and create something warm, comforting, and filling.
That lesson stayed with me throughout my cooking career.
Today, many families need gluten-free meal options, whether because of celiac disease, gluten sensitivity, or personal preference. The challenge is finding recipes that still feel satisfying and comforting.
That’s exactly why I created this gluten free casserole recipe.
It delivers creamy texture, savory flavor, golden-brown cheese, and wholesome ingredients without relying on gluten-containing products. Even family members who don’t follow a gluten-free diet enjoy this casserole because it simply tastes good.
