In a small bowl, stir together Creole seasoning, salt, and pepper. Sprinkle both sides of catfish fillets with seasoning mixture.
In a 12-inch enamel-coated cast-iron skillet, melt butter over medium-high heat. Add catfish, and sear until fillets are golden brown, about 5 minutes. Carefully turn fillets; add lemon juice.
In a small bowl, stir together oil, garlic, thyme, and zest. Pour oil mixture over fillets, and sprinkle with cornbread crumbs.
Bake until golden brown, about 4 minutes. Garnish with thyme, if desired.
Notes
*If you only have fresh cornbread, bake it for 1 hour in a 200° oven to dry it out.
