Heat olive oil in a large skillet over medium heat, then add the sliced smoked sausage and cook until browned and fragrant.
Stir in the chopped onion and bell peppers, cooking until they soften and begin to turn golden at the edges.
Add the garlic, Cajun seasoning, smoked paprika, salt, and pepper, stirring for about 30 seconds until the garlic smells toasty.
Pour in the rinsed rice and stir well so every grain is coated in the seasoned sausage drippings.
Add the chicken broth, scraping the bottom of the pan to release any browned bits, and bring the mixture to a gentle boil.
Reduce the heat to low, cover the skillet tightly, and simmer for about 15 minutes, or until most of the liquid is absorbed.
Quickly arrange the shrimp on top of the rice, cover again, and cook for another 5 minutes, until the shrimp are pink and the rice is tender.
Remove from the heat, let rest covered for 5 minutes, then fluff the Shrimp Sausage Dirty Rice Recipe gently with a fork and garnish with green onions before serving.
