To make this Alice Springs Chicken (copycat) gluten-free, confirm that the bacon and shredded cheddar cheese are certified gluten-free or labeled free from gluten-containing additives. Some bacon products and pre-shredded cheeses may contain flavorings, preservatives, or anti-caking agents that could include gluten or have cross-contact concerns. The chicken, salt, black pepper, and green onions are naturally gluten-free, but all packaged ingredients should still be checked carefully. Use clean cookware, utensils, cutting boards, and baking dishes to prevent gluten contamination.
