Preheat the Air Fryer to 375 degrees F, air fryer setting.
In a skillet, melt 4 tablespoons of butter over medium heat. Saute the celery and onion in the melted butter until soft and the onion is translucent.
Place the cornbread crumbs into a large bowl. Add the sauteed celery and onion - be sure to use a spatula to scrape all of the butter from the pan and into the breadcrumb bowl as well.
Combine the chicken broth, remaining 4 tablespoons of melted butter, garlic salt, pepper, and onion powder. Add the eggs to the broth mixture and whisk to fully combine.
Pour the liquid mixture over the breadcrumb mixture and toss to combine and mix thoroughly.
Butter a casserole dish that will fit in your air fryer. I suggest a deep dish 8” round casserole dish.
Spread the cornbread mixture into the buttered dish and cover with aluminum foil.
Cook in the air fryer at 375 degrees F, air fryer setting, for 30-45 minutes, covered until the stuffing mixture is cooked through.
Uncover, stir, and bake for 5 minutes more until the top is golden brown.
Sprinkle with chopped fresh parsley.
Plate, serve, and enjoy!
