Cajun Shrimp Close Up

This recipe is SO simple, and packed with flavor. I was gifted the cast iron shrimp pan for Mother’s Day, and I knew I had to make something fantastic. My older two sons were at my parent’s for a sleepover, so I could up the spicy factor for dinner without much complaint!

1. If you have a premade Cajun seasoning blend on hand, you can use 2 tbsp instead of the full blend below. I really like Bill Baron’s Cajun Seasoning.

2. While the cast iron is not necessary, I have to say, it’s such a game changer. It holds the juices and moisture while the shrimp cook, making the flavor that much more delicious
