Recipe Q&A

What type of sausage is best for this dish?

Andouille sausage brings a smoky and spicy flavor that complements the Cajun seasoning well. Smoked turkey sausage is a lighter substitute.

Can I use different pasta types?

Penne or fettuccine work best to hold the sauce, but other short or ribbon pastas can be used based on preference.

How is the Cajun seasoning incorporated?

Cajun seasoning is added during shrimp cooking and combined in the sauce to balance heat and flavor throughout the dish.

What is the purpose of chicken broth in the sauce?

Chicken broth adds depth and helps thin the cream sauce slightly, creating a smooth and rich consistency.

How can I adjust the spice level?

Add cayenne pepper or hot sauce for more heat, or reduce Cajun seasoning to soften spice intensity.

What garnishes enhance this skillet?

Fresh chopped parsley adds a bright herbal note and color contrast to the rich creamy sauce.
