Making Cajun Shrimp Dirty Rice is a straightforward process. Follow these easy steps:

1. Heat Oil: In a large skillet, heat the olive oil over medium heat.
2. Sauté Aromatics: Add the diced onion and bell pepper (if using) to the skillet. Cook until softened, about 3-5 minutes.
3. Add Garlic: Stir in the minced garlic and sauté for an additional minute until fragrant.
4. Incorporate Shrimp: Add the peeled shrimp into the skillet. Season with Cajun seasoning, salt, and pepper. Cook until the shrimp turn pink, about 3-5 minutes.
5. Add Rice: Stir in the uncooked rice, making sure it mixes well with the shrimp and aromatics.
6. Pour in Broth: Add the chicken broth to the skillet, bringing the mixture to a boil.
7. Simmer: Once boiling, reduce the heat to low. Cover and let it simmer for about 15-20 minutes, or until the rice is tender and has absorbed all the liquid.
8. Fluff and Serve: Remove the skillet from heat. Fluff the rice with a fork and let it sit covered for an additional 5 minutes.
9. Garnish: Before serving, sprinkle fresh parsley on top for a touch of color and flavor.

With each step, you will be whisked away to the rich culinary tradition of Cajun cooking, all from the comfort of your home.
