Yes. Reduce the amount of Cajun seasoning or use a mild homemade blend for a creamier, less spicy dish.
Can I use frozen shrimp?

Penne is ideal because it holds the creamy sauce well, but fettuccine, rigatoni, and linguine are also excellent choices.

It’s best served fresh, but leftovers reheat well for lunch or dinner.
