Notes

Optional ingredients.
  • Cranberry sauce. - I personally don't add my gluten-free cranberry sauce to the casserole. I prefer it on the side. But if you love cranberry sauce, feel free to drizzle some in. If you are using turkey in your casserole, you can toss it in the cranberry sauce for a delicious addition.
  • Mac and cheese. - I don't usually have a ton of leftovers when I make my gluten-free mac and cheese for Thanksgiving, so I don't typically add it. But if you do, and you love it, feel free to add some to the casserole.
  • Cheddar cheese. - If you don't have any leftover stuffing but you have a ton of mashed potatoes, feel free to top with the mashed potatoes and then sprinkle the top with cheese before baking. It will create a delicious gluten-free cheesy potato casserole.
  • Gluten-free bread crumbs. - If you don't have any leftover gluten-free stuffing but want that breading topping, feel free to use some gluten-free bread crumbs on top instead for that little bit of crispy breaded topping.
 
Tips and tricks.
  • Use what you like and not what you don't. - Don't try and add a recipe to your casserole just because it's a leftover. If you don't like it by itself, you aren't likely to like it in this leftover casserole either.
  • Don't be afraid to experiment. - This leftover Thanksgiving casserole is honestly never the same from year to year, and to me, that's the fun part. Using up leftovers without them getting boring is what this gluten-free casserole recipe is all about.
