Heat the vegetable oil in a large Dutch oven over medium-high heat.

Add the sliced andouille sausage and cook for about five minutes until nicely browned on both sides. Browning the sausage develops deep, smoky flavor and leaves behind flavorful bits in the bottom of the pot that will season the rest of the dish.

Remove the sausage with a slotted spoon and set it aside, leaving the drippings in the pot.

Add the chicken pieces to the same pot.

Season lightly with a little Cajun seasoning and cook until browned on all sides, about six to eight minutes. The chicken doesn’t need to be fully cooked yet because it will continue cooking later with the pasta and broth.

Once browned, transfer the chicken to the plate with the sausage.

Using the same pot, add the diced onion, celery, and green bell pepper. This combination is known in Cajun cooking as the “Holy Trinity,” forming the flavorful base of many Louisiana dishes.

Cook the vegetables for about 5–6 minutes, stirring occasionally, until they become soft and fragrant. Add the minced garlic during the last minute of cooking to prevent it from burning while releasing its rich aroma.

Return the cooked sausage and chicken to the pot.

Stir in the Cajun seasoning, smoked paprika, garlic powder, onion powder, dried thyme, black pepper, and bay leaves. Mix everything well so the meat and vegetables are evenly coated with the spices.

Pour in the diced tomatoes with their juices and the chicken broth. Stir thoroughly, scraping the bottom of the pot to loosen any browned bits, which add incredible depth of flavor.

Bring the mixture to a gentle boil.

Once the broth reaches a boil, add the uncooked pasta.

Reduce the heat to medium-low and stir frequently during cooking to prevent the pasta from sticking together or settling at the bottom of the pot.

Simmer for 12–15 minutes, or until the pasta is tender and most of the liquid has been absorbed. The finished dish should be rich, creamy, and saucy rather than dry.

Taste and adjust the seasoning with additional Cajun seasoning or salt if needed.

Remove the bay leaves before serving.

Sprinkle the chopped parsley and sliced green onions over the pastalaya for a burst of freshness and color.

Serve hot, either on its own or with crusty French bread, garlic bread, or a simple green salad.

For an extra kick, offer your favorite hot sauce at the table.
