Absolutely, adapting this Brunch Casserole for a gluten-free lifestyle is simple and ensures that everyone can indulge in this comforting dish without hesitation. To guarantee it meets gluten-free standards, select a sausage that is labeled as gluten-free; many sausages contain fillers that may include gluten. Next, double-check your hash browns — though inherently gluten-free, as they're made from potatoes, they can sometimes be processed in facilities that handle wheat products. Opt for a brand that confidently asserts its gluten-free status. As for the remaining ingredients — eggs, milk, cheese, and spices — they are naturally gluten-free.
