Cajun Shrimp Pasta

Seafood is one of my favorite lean, quick-cooking protein sources which you’ve probably figured out by now due to my extensive and growing collection of seafood recipes. Fortunately, my entire family loves seafood as well. From Shrimp and Broccoli Penne, Pesto Pasta with Shrimp and Peas, to Lemon Shrimp Pasta with Arugula, we enjoy shrimp at least one or two nights a week.

Cajun Seasoning

To help save time and get dinner on the table faster during busy weeknights, I always keep a bag of frozen shrimp stashed in my freezer. Most recently I decided to use a bag of frozen shrimp I had on hand to create a flavor-packed pasta recipe using Cajun spices, peppers and onions.

To begin cooking, simply prep the vegetables, boil the pasta and begin seasoning the shrimp. If using frozen shrimp, be sure to fully defrost before use. Then, pat them dry and season liberally with Cajun spices.

Next, heat half of the olive oil in a deep skillet. Cook the peppers in onions with garlic until they begin to caramelize, and remove them from the pan. Now, add the rest of the oil and shrimp until they turn a bright pink color. Be sure to turn them every 2-3 minutes! Finally, combine all the ingredients, add salt and pepper, and garnish with minced scallions.

Tips for Cooking with Shrimp

  • Use frozen shrimp for convenient and affordable recipes.
  • Although shrimp are labeled in size as small, medium, and large, there is no official regulation. Instead, look for the count number on the bag to get the most bang for your buck.
  • Buy de-veined shrimp to make preparation super easy.
  • Cook shrimp in their shells to increase their flavor.
