To make this recipe gluten-free, just swap out the regular crackers for gluten-free butter crackers (like gluten-free Ritz or a similar option). Also, double-check that your half and half, cheese, and any spices you use are gluten-free—most are, but it never hurts to be sure. With these easy swaps, you’ll still get that creamy, cheesy goodness and crunchy topping, totally gluten-free!
