Heat the olive oil in a large skillet over medium heat. Add the sliced sausage and cook until browned on both sides, about 5 minutes.
Add the diced onion and bell peppers to the skillet. Cook until the vegetables soften, about 4 minutes.
Stir in the minced garlic, Cajun seasoning, paprika, salt, and black pepper. Cook for 1 minute until fragrant.
Add the rice and stir to coat it with the oil and seasonings. Pour in the chicken broth and bring the mixture to a boil.
Reduce the heat to low, cover the skillet, and simmer for 18 minutes until the rice is tender and the liquid is absorbed.
Remove the skillet from the heat and let it rest covered for 5 minutes. Fluff the rice with a fork and top with sliced green onions before serving.
