This old-fashioned Southern Cornbread Dressing is my grandmother's recipe, made with homemade cornbread, biscuits, stuffing mix, celery, and onions. Baked until golden with a soft, tender center and slightly crisp top, it's a family tradition for Thanksgiving and Christmas.
Heat oven to 350 degrees. Prepare a 10x15 (large 4.8 quart) baking pan with cooking spray. Set aside.
Add butter to a pan and saute celery and onions until tender.
Crumble cornbread and biscuits or bread into a large bowl. Add stuffing mix. Add cooked vegetables. Add in eggs and 4 cups of stock. Mix well. Add in salt, pepper, and celery salt. Mix again. Dressing mixture should be loose but not soupy. If too thick, add more stock. Pour dressing into prepared pan and bake for 30 - 45 minutes, until the top is golden around the edges.
Remove from oven and let cool for 5 minutes. Cut into squares or scoop out with a large spoon and serve.
