Preheat the oven to 350°F. Grease a 9x13-inch baking dish with cooking spray.
In a large mixing bowl, crumble the cornbread and bread slices into large chunks.
In a medium skillet, melt 4 tablespoons of butter over medium-high heat. Add the onion, celery, and sage. Cook, stirring frequently, until tender, about 5 minutes. Add the remaining 6 tablespoons of butter and stir until melted. Transfer the onion mixture to the bowl with the cornbread.
To the cornbread-onion mixture, add the chicken stock, beaten eggs, salt, and pepper, and stir just until just combined. Spoon into the prepared baking dish.
Bake for 45 minutes or until golden brown and the mixture is set. Let cool for a few minutes before serving. Cover and refrigerate any leftovers for up to 4 days.
Notes
You could substitute 2 teaspoons of fresh sage for the 1 teaspoon of dried sage.
Stale bread is perfect for dressing as fresh bread tends to become soggy in the cooking process.
I like to crumble the cornbread and tear the bread as you get extra texture to the dressing.
Not a fan of dried sage? You can try dried thyme, dried rosemary, or dried parsley.
Other things you can add to the dressing include dried fruit, chopped nuts, cooked protein, or vegetables.
Careful not to overcook the cornbread dressing as it’ll lead to a dry dressing.
If you think the top of your dressing has browned too quickly, cover it with foil so it can continue to bake without burning.
