Ingredients

Instructions

  1. Step 1: In a large heavy pot over medium heat, combine 1/3 cup vegetable oil and 1/3 cup all-purpose flour. Stir continuously for 15-20 minutes until the mixture turns a deep brown color, resembling chocolate, creating a dark roux.
  2. Step 2: Add 1 large diced onion, 1 medium diced green bell pepper, and 3 diced celery stalks to the roux. Cook, stirring often, for 6-8 minutes until vegetables are soft and fragrant.
  3. Step 3: Stir in 4 minced garlic cloves and cook for 1 minute until aromatic.
  4. Step 4: Pour in 4 cups chicken broth and 14 oz canned diced tomatoes with their juice, stirring to combine. Add 2 tbsp Cajun seasoning and 2 whole bay leaves.
  5. Step 5: Bring the mixture to a boil, then reduce heat to low and simmer uncovered for 45 minutes, stirring occasionally until broth thickens slightly.
  6. Step 6: Add 12 oz sliced Andouille sausage and 1 lb peeled, deveined raw shrimp. Simmer for 5-7 minutes until shrimp turn pink and are cooked through.
  7. Step 7: Remove bay leaves. Stir in 1/4 cup chopped fresh parsley and 3 sliced green onions. Serve hot over 4 cups cooked white rice.
