Cook the rice according to the package.
Sauté the diced onion, pepper, and celery in 1 tbsp butter over medium heat for 6 minutes. Add the beans, 1 tsp Cajun seasoning, and a splash of water and simmer 5 minutes, mashing a few beans to thicken. Stir in the rice.
Rub the catfish with the remaining Cajun seasoning.
Heat the remaining butter in a cast-iron skillet over medium-high heat and cook the fish 3 minutes per side until blackened and flaky.
Serve the fish over the red beans and rice, topped with green onions.
