Measure rice into a pot and rinse. Add water and bring to a boil. Reduce heat, cover and simmer for 20 minutes.
In a large cast iron skillet, melt the butter over medium heat.
Add onion, bell pepper, and celery to the skillet and sauté until tender.
Once the vegetables are soft, season with cajun seasoning, chili powder, salt and pepper.
Add the diced tomatoes, tomato sauce, Worcestershire sauce, and Louisiana hot sauce.
Stir to combine all ingredients and simmer for 25-30 minutes.
Add the shrimp to the skillet. Cook the shrimp in the sauce flipping after 3-4 minutes. Continue to cook for an additional 3 minutes or until the shrimp are pink and cooked through.
To serve, scoop 1/2 cup of rice onto a plate. Generously cover the rice with the shrimp creole.
