In a Dutch Oven, add 2 tbs of the oil and set heat to medium. When the oil is hot, add in the chicken.
Season the chicken with the above spices and cook thoroughly. When finished, remove and set aside.
Add the smoked sausage, and cook until nice and crispy on both sides. Remove it and set it aside.
Add the butter to the pan and then add the shrimp. Season with the same spices used for the chicken. Cook until pink and no longer translucent. This should only take about 4-5 minutes. Remove it and set it aside.
Add the remaining 2 tbs of the oil then add the onion, celery and bell pepper. Cook that for at least 15-20 minutes until it turns a rich brown color, stirring frequently.
Add the garlic and cook for one minute, just until garlic becomes fragrant.
Add the chicken and sausage back in, then the rice. Give it a quick stir then add the Cajun blend. Stir in the broth, place the bay leaves on top, place the lid on and reduce to a simmer. Cook for about 20 minutes until the rice is fully cooked.
Remove the lid and take out the bay leaves. Stir in the shrimp and it is ready to serve!
You can add salt if needed.
