The day before preparing the stuffing, make the cornbread.
Preheat the oven to 350°F. Use a serrated knife to slice the cornbread into ¾” cubes. (See post for an image of how I sliced my cornbread.)
Transfer the cornbread cubes to a baking sheet and toast in the oven for 20 minutes.
Meanwhile, in a large skillet, sauté the onion and celery over medium heat for 7-10 minutes, until soft. Add a splash of vegetable broth if the veggies start to stick.
Add the toasted cornbread, parsley, sage, thyme, salt, and pepper to the pan. Toss gently and allow to toast for 1-2 minutes over the heat.
Turn off the heat and pour on the vegetable broth. Toss gently 2-3 times, careful not to break too many pieces.
Transfer the mixture to a medium sized baking dish. Cover with aluminum foil and bake for 30 minutes. Then uncover and bake 25-30 minutes more until the top of the stuffing is golden brown.
Let cool 5 minutes before serving. Garnish with fresh sage, thyme, and/or parsley.
