Heat the olive oil in a heavy-bottomed pot or Dutch oven over medium heat.
Add the sliced chicken andouille sausage and sear for 4 to 5 minutes until beautifully browned and caramelized.
Toss in the diced onion, green bell pepper, and celery, sautéing for 6 minutes until the vegetables soften and become translucent.
Stir in the minced garlic and creole seasoning, cooking for 60 seconds until the spices are toasted and fragrant.
Add the dry brown rice, crushed tomatoes, and chicken broth, stirring well to combine and scraping any browned bits from the bottom.
Bring the mixture to a gentle boil, then reduce the heat to low, cover tightly, and simmer for 35 to 40 minutes until the rice has absorbed the liquid.
Fold in the shrimp, cover again, and cook for an additional 4 to 5 minutes until the shrimp are pink, curled, and perfectly tender.
Season with sea salt and black pepper to taste, then garnish with a sprinkle of fresh chopped parsley before serving hot.
