Clean the catfish fillets and pat them dry with paper towels.
Drizzle both sides of the catfish fillets with olive oil.
Sprinkle both sides of the catfish fillets with cajun spice.
Rub to ensure both sides are evenly coated with seasoning.
Slice a lemon into 8 round slices.
Place the catfish fillets on the baking dish in an even layer. Place each fillet on top of 2 lemon slices. You can skip this step if you choose.
Put in the oven and bake for 15-18 minutes or until well done.
Enjoy!
Notes
OH YEAH . . . Before I forget: If your catfish is cold, allow it to come to room temperature before baking. You want it to cook evenly. About 15 minutes out of the refrigerator should be fine.
