Preheat the oven to 450°F. Prepare a roasting pan by lining the bottom with foil and spraying the roasting rack with oil.
Mix the almond meal, salt, pepper, garlic powder, onion powder, paprika, dried thyme, dried oregano, and cayenne pepper in a shallow bowl.
In another shallow microwave-safe dish, melt the butter in the microwave.
Blot the fish fillets dry with paper towels.
Dip each catfish fillet in the melted butter.
Dredge each fillet in the almond meal mixture, pressing to ensure the coating adheres.
Place the coated fish fillets on the prepared roasting rack. Spray them with oil.
Place the pan in the preheated oven. Bake the fish for about 15 minutes, until crisp and golden on the outside and tender and opaque inside. Serve immediately.

Notes
The nutrition info assumes that almond meal was used as a coating. It reflects the fact that some of the butter and almond meal mixture will be left behind in the dishes. You still need all of it to properly coat the fish, but you will not use all of it.
If your catfish fillets are very uneven - one thin and one thick - you can slice the thick one into two thinner fillets.
You can keep the leftovers in the fridge, in an airtight container, for 3-4 days. They won't be as good as the freshly baked fish - the coating will lose its crispiness. It's best to reheat the leftovers in a 350°F oven for about 10 minutes or until heated through, but microwaving them gently works too.
