Recipe FAQ

What type of sausage works best?

Andouille sausage adds a smoky, spicy flavor ideal for this dish, but smoked turkey sausage or chicken sausage can be used as alternatives.

Can I substitute the pasta with gluten-free options?

Yes, gluten-free pasta like penne or fettuccine works well without sacrificing texture or taste.

How do I prevent the shrimp from overcooking?

Sauté the shrimp quickly until just pink and opaque, usually 2-3 minutes, then remove them from the heat to avoid toughness.

What adds the Cajun flavor in the sauce?

Cajun seasoning is incorporated during cooking along with sautéed vegetables, creating a spicy, smoky depth in the creamy sauce.

Can I add extra heat if desired?

For more spice, add a pinch of cayenne pepper or a few dashes of hot sauce during cooking to enhance the heat level.

What side dishes pair well with this meal?

A crisp green salad and garlic bread complement the creamy pasta, while a lightly chilled Chardonnay provides a balanced accompaniment.
