Preheat the oven to 375F.
To a 9x13-inch baking dish add the rice, drained beans, onion, pepper, celery, garlic, butter, tomato paste, Cajun seasoning, thyme, garlic powder, onion powder, and salt. Stir to combine.
Pour in the Worcestershire sauce and vegetable broth, stirring to combine. Cover tightly with a lid or foil.
Bake at 375F for 25 to 30 minutes, or until the rice is cooked through. While the rice bakes, pan-fry the sliced sausages in a lightly oiled pan until golden, just 4-5 minutes.
Remove the rice from the oven and stir in the pan-fried sausage and parsley. If the rice is a little liquidy you can return it to the oven to bake, uncovered, for 5 minutes. Otherwise, it is ready to serve. Enjoy!
