To make this Tasty Taco Bake with Crescent Rolls gluten free, replace the regular crescent rolls with certified gluten-free crescent-style dough or a gluten-free pastry dough suitable for baking. Use certified gluten-free taco seasoning, as some seasoning packets may contain gluten-based fillers or anti-caking agents. Confirm that the shredded cheese, sour cream, nonstick cooking spray, and any toppings are gluten free and processed without cross-contamination. Bake according to the gluten-free dough package directions, as the texture and baking time may vary.
