Instructions:
- To make the seasoning, whisk together all of the ingredients for the Cajun seasoning in a small bowl until thoroughly combined.
- Remove from the equation.
- To make the roux, heat the oil in a medium-sized pot (Note 6) over medium heat.
- Mix in the butter and flour.
- Cook, stirring constantly, for about 15 minutes, or until the roux has developed a dark caramel color.
Cook the vegetables:
- In the same saucepan as the roux, add the chopped bell peppers, onions, and carrots.
- Stir in the roux until it is thoroughly combined.
- Cook, stirring periodically, for about 10 minutes, or until veggies soften and become fragrant.
Simmer:
- In the same saucepan, combine the crushed tomatoes, chicken broth, scallions, and Cajun seasoning.
- Bring to a boil, then reduce to a low heat and continue to cook over medium heat.
- With the lid on, cook for 1 hour.
- Uncover and add the meat. Stir the shrimp and sausage into the saucepan.
- Cook, uncovered, for 5 minutes or until shrimp is opaque and cooked.
- Remove the pan from the heat and serve (Note 7).
