Place Colorful Goldfish crackers, Ritz crackers, and Creole seasoning in a resealable bag and crush to tiny pieces. Pour the crushed contents into a wide bowl. Pour Ranch dressing into another wide bowl.
Dredge the chicken strips in the Ranch, then coat with the colorful cracker mixture. Repeat for each of the pieces.
Line a 9x13 pan lined with tin foil and lightly coat with a non-stick spray. Place the chicken pieces in the pan. Cook in the preheated oven for 20-25 minutes.
