Creating Easy Cajun Chicken Étouffée is a breeze if you follow these simple steps:

1. Prepare the Ingredients: Dice the chicken and chop the vegetables. Gather all the ingredients together for easier preparation.
2. Make the Roux: In a large skillet, heat the vegetable oil over medium heat. Gradually whisk in the flour. Stir constantly until the roux turns a light brown color, about 5-7 minutes.
3. Sauté the Vegetables: Add the chopped onion, bell pepper, and celery to the roux. Cook for about 5 minutes until the vegetables are softened.
4. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
5. Incorporate Chicken: Add the diced chicken to the skillet. Cook for 5-7 minutes, stirring frequently, until the chicken is browned.
6. Add Broth and Seasonings: Pour in the chicken broth and add the Cajun seasoning, salt, black pepper, and cayenne pepper (if using). Stir well to combine.
7. Simmer the Étouffée: Bring the mixture to a gentle simmer. Reduce the heat to low and let it cook for about 15-20 minutes, stirring occasionally, until the chicken is cooked through and the sauce thickens.
8. Taste and Adjust: Before serving, taste the étouffée and adjust seasonings as needed.
9. Serve: Ladle the chicken étouffée over a bed of cooked white rice. Garnish with sliced green onions.
