Bake your biscuits and cornbread up to 2 days ahead of time and leave them out on the counter to cool and dry out. If you buy pre-made biscuits or cornbread you should leave these out for a day or two also.
When you are ready to make your dressing start by pouring the broth into a large saucepan and then add celery and onions. Bring to a boil and then reduce to a simmer and let it cook until the celery and onion are soft.
Preheat oven to 400 degrees F.
In a large pot finely crumble the cornbread and biscuits, stirring to combine them.
When your broth is ready pour it over the bread mixture 1 cup at a time, stirring it together, until you reach a consistency like oatmeal. If you need to add more broth you don’t have to heat anymore up you can just add it straight to the mixture. Note: Make sure all of your celery and onions go into the mixture even if you don’t use all of the broth.
Next add salt and poultry seasoning a little at a time. Take your time, stir everything together well, and keep tasting until you think you have it right. Note: The sage flavor in the poultry seasoning does get stronger as it bakes so err on the side of too little rather than too much!
When you have the flavor where you like it add the eggs, stirring everything together until it is fully combined.
Pour the cornbread mixture into a 9 x 13 casserole dish and let it bake at 400 degrees F for 30-40 minutes, or until the outer edges are firm and the middle doesn't jiggle.
Remove from the oven and serve with turkey and gravy!
