Want to make this recipe gluten-free? It’s actually really simple! Just swap out the regular bread for your favorite gluten-free bread. These days, there are plenty of great gluten-free options that hold up really well in a bake like this. You’ll still get that same delicious, custardy texture without the gluten. Also, make sure your Bisquick mix (if using a substitute) and any pre-grated cheese you use are certified gluten-free to avoid any sneaky gluten. With these small tweaks, you’ll have a gluten-free version that’s just as cheesy and satisfying as the original.
