01 - Melt butter in a large skillet over medium heat. Add celery, onion, and carrot. Sauté until softened, approximately 5–7 minutes. Remove from heat and set aside.
02 - In a large mixing bowl, combine crumbled cornbread, sautéed vegetables, parsley, salt, pepper, sage, thyme, and garlic powder. Mix thoroughly to distribute seasonings evenly.
03 - Pour broth and beaten eggs over the cornbread mixture. Stir until evenly moistened and mixture holds together when squeezed. Add additional broth tablespoon by tablespoon if mixture appears too dry.
04 - Using a 2-tablespoon scoop or spoon, portion mixture and gently roll into balls. Arrange on a baking sheet and refrigerate for 20 minutes to firm structure for breading.
05 - Set up three shallow bowls: place flour in the first, beaten eggs in the second, and panko breadcrumbs in the third. Line up in assembly order for efficient coating.
06 - Roll each chilled ball lightly in flour, shaking off excess. Dip in egg mixture, allowing excess to drip off. Press firmly into panko, ensuring complete coverage. Transfer to a clean surface.
07 - Heat 2 inches of neutral oil in a deep pot or skillet to 350°F. Fry balls in batches of 6–8 for 2–3 minutes until deep golden brown and crispy throughout. Maintain oil temperature between batches.
08 - Remove balls with a slotted spoon and transfer to a paper towel-lined plate to drain excess oil. Serve immediately while hot and crispy.
