To make this Joanna Gaines’ Pecan Pie Recipe gluten-free, use a certified gluten-free 9-inch pie crust or homemade gluten-free pie dough. Confirm that the light corn syrup, brown sugar, salted butter, eggs, cinnamon, Ancho chili powder, pecans, and toppings are gluten-free and free from cross-contact. Some spice blends, nuts, and prepared toppings may be processed in facilities that handle wheat, so check labels carefully. Use clean utensils, a clean pie plate, and separate prep surfaces to prevent cross-contamination.
