Brown the sausage: Heat a skillet over medium-high heat. Then add the sliced sausage in a single layer. Cook for about 2 minutes per side until lightly browned. Transfer the sausage to a plate and set aside.

Make the roux: In a large pot over medium-low heat, add oil. Whisk in flour gradually until combined. Continue to cook, stirring constantly for about 20 to 30 minutes until the mixture reaches a brown color as milk chocolate. Keep a close eye on the roux and not to let it burn, adjusting the heat if needed. You can add more flour or oil if necessary.

Cook the veggies: Add veggies, garlic, bay leaves, and green onions. Then add chicken broth to the roux. Turn the heat to medium and stir well. Bring to a boil and cook for 5-6 minutes or until the veggies are slightly tender.

Season the broth: Add Cajun seasoning and salt. Taste and add more if needed.

Cook the seafood: Add seafood mix and cook for 2 minutes. Then add shrimp and cook for 3 minutes or until the shrimp turns pink. Add back the cooked sausages and mix well. Serve warm over rice and enjoy!
