Ingredients for Cajun Shrimp Pasta

Ingredient Info and Substitution Suggestions

SHRIMP – You can use frozen or fresh, but if they are frozen, allow them to thaw completely before beginning and pat them dry. You can typically find grilling shrimp at the seafood counter at your local grocery store.

PASTA – Penne pasta is our go-to for this dish, but you can easily substitute it with your favorite noodle shape. Ziti, rigatoni, fusilli, and cavatappi are all great substitutes but even long noodles such as fettuccine, spaghetti, or angel hair would work well.

SEASONING – I highly recommend using our homemade cajun seasoning. Not only can you use it on a ton of other recipes, but it’s super quick to make and packs powerful flavor!

Frequently Asked Questions & Expert Tips

How do you know when shrimp is done cooking?

Shrimp does not take long to cook, which also means it can easily be overcooked. The shrimp will curl and turn opaque with pink and red hues when it is finished cooking. Overcooked shrimp tend to turn a whiteish grey and are rubbery in texture.

How do you store leftover cajun shrimp pasta?

Store leftovers in an airtight container kept in the refrigerator for up to 3 days. Reheat on the stovetop over medium-low heat just until warmed through. You can add a dash of water or additional cream to loosen it back up if needed.

Serving Suggestions

Though this cajun shrimp pasta is hearty and satisfying all on its own, you can pair it with chunks of bread for dipping and mopping up any excess sauce. It also pairs well with a crisp dinner salad on the side. Optionally garnish with fresh chopped parsley and extra parmesan cheese.
