To make these Cheesy Garlic Bites gluten free, replace the canned biscuit dough with a certified gluten-free biscuit dough or gluten-free refrigerated dough if available. You can also use homemade gluten-free biscuit dough. Be sure to check that the garlic powder, Italian seasoning, shredded mozzarella, and marinara sauce are all certified gluten free, since some packaged products may contain additives or cross-contact risks. Because gluten-free dough can be a bit more delicate, handle it gently when dipping and coating, and watch the baking time closely, as it may vary slightly depending on the brand used.
