Recipe FAQs

What type of sausage works best?

Smoked sausages like andouille or kielbasa add a smoky depth, but turkey or chicken sausages can be used for a lighter variation.

Can I adjust the spice level?

Yes, adding extra Cajun seasoning, cayenne pepper, or hot sauce can increase the heat to your preference.

How should I cook the pasta?

Boil penne in salted water until al dente, then drain thoroughly before mixing with the sauce to maintain texture.

What alternatives exist for heavy cream?

For a lighter option, substitute half-and-half or use a dairy-free cream alternative, though the sauce may be less rich.

Can I prepare this ahead of time?

Yes, prepare the components separately and combine just before serving to keep textures fresh and flavorful.
