To Make This Recipe Gluten-Free: To prepare a gluten-free version of this sausage gravy, replace the all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum or another binding agent. Additionally, ensure your breakfast sausage is certified gluten-free, as some pre-seasoned varieties may contain gluten-based fillers or flavorings. Follow the same preparation steps, whisking carefully to achieve a smooth, thickened texture.
