Want to make this recipe gluten-free? Easy fix! Just double-check that your sausage and cheese are certified gluten-free (most are, but it’s always good to check). The rest of the ingredients—squash, apples, onions, herbs, and Gruyère—are naturally gluten-free, so the only real switch you might need is the sausage. If you’re serving this to someone with gluten sensitivities, this small change will make sure everyone can enjoy this delicious dish without worry!
