Recipe Help

What type of sausage is best for this dish?

Andouille sausage provides a smoky, spicy flavor that complements the Cajun seasoning well. Smoked turkey or chicken sausage can be used for a milder taste.

Can I use a different pasta shape?

Penne and fettuccine work best to hold the creamy sauce, but other medium-width pasta like rigatoni or linguine can also be used.

How can I adjust the spice level?

Adjust the Cajun seasoning amount or add a pinch of cayenne pepper for extra heat. Reducing seasoning will mellow the spice.

What is the best way to cook shrimp for this meal?

Sauté peeled, deveined shrimp briefly until just pink to avoid overcooking, ensuring tender and juicy seafood.

Can this be made gluten-free?

Yes, by substituting regular pasta with gluten-free pasta and checking that sausage and broth are gluten-free.

How should leftovers be stored?

Store in an airtight container in the refrigerator and consume within 2 days. Reheat gently to preserve texture and flavor.
