01 - Melt butter in a large skillet over medium heat. Add diced celery, onion, and carrot. Sauté until softened, approximately 5 to 7 minutes. Remove from heat and set aside.
02 - Combine crumbled cornbread, sautéed vegetables, parsley, salt, pepper, sage, thyme, and garlic powder in a large mixing bowl. Toss thoroughly to distribute seasonings evenly.
03 - Pour broth and beaten eggs over the cornbread mixture. Stir until evenly moistened and mixture holds together when pressed. Add additional broth by the 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 for easier handling.
05 - Prepare 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 into egg mixture, ensuring complete coverage. Press firmly into panko, coating thoroughly and shaking off loose crumbs.
07 - Heat 2 inches of neutral oil in a deep pot or skillet to 350°F. Fry breaded balls in batches without overcrowding, approximately 2 to 3 minutes per batch, until deep golden brown and crispy throughout.
08 - Transfer fried balls to a paper towel-lined plate or wire rack to drain excess oil. Serve immediately while hot and crispy, accompanied by gravy or sauce of choice.
