How to Make It
Bring 8 cups chicken broth to a boil in a large Dutch oven over medium-high heat; stir in chopped celery and onion. Reduce heat to medium, and simmer 20 to 30 minutes or until celery and onion are very tender. Remove from heat, and stir in 4 cups chicken broth. Cool 30 minutes.
Meanwhile, stir together Cornbread Crumbles and next 2 ingredients in a very large bowl.
Preheat oven to 350°. Stir broth mixture, eggs, and next 4 ingredients into cornbread mixture until thoroughly combined. If needed, stir in up to 2 more cups chicken broth, 1/4 cup at a time, until mixture is slightly soupy.
Spoon mixture into 2 (13- x 9-inch) lightly greased (with cooking spray) baking dishes. Bake at 350° for 50 to 60 minutes or until done and top is light brown.
