Sometimes Shrimp is the Only Acceptable Answer to the Question, Y'all...

I almost always have shrimp on hand in my freezer. Mark and I both love it. And since shrimp don't take a long time to cook, it's an easy lunch or dinner protein choice for me to whip up within the hour.

So, when I had a craving for creamy Cajun tartar sauce, the only question that I had to answer next was what to serve alongside of the condiment. And, it didn't take me long to figure out that I wanted to update my Louisiana fried shrimp recipe. It had certainly been a while since I revisited the original. And it was great to look at one of the earliest recipes on my blog with fresh eyes.

I honestly didn't change much, y'all. But, I did use all of my tried-and-tested ingredients and cooking methods. As a home cook, I've grown a lot over the years. So, I'm passing everything I know over to you now.

Partly because I just can't help but share. And partly because more and more people are finding out that they are gluten intolerant or celiac.

So, I'm still here doing the best I can to share recipes like this authentic Cajun fried shrimp. I'm doing my part to preserve the Cajun and Creole culture for those of us who have to be grain and gluten free.

And I Have Just The Right Flour for It, Too...

And, I'm using my favorite flour, cassava, for this recipe. It's sooo amazing, y'all! It's the most wheat-like choice for frying. It's not expensive or hard to find, either. And it gives this grain and gluten free Cajun fried shrimp recipe its super authentic texture, too.

So, even if you've stumbled onto my blog for the first time as a wheat-eater, I think if you give cassava flour a try for Louisiana fried seafood you'll be MORE than pleased. Indeed.

How to Make Cajun Fried Shrimp

Start the Cajun fried shrimp by grabbing all of the main ingredients. You'll also need a generous amount of your favorite cooking oil, too:

Ingredients for Cajun fried shrimp. — Peeled, deveined shrimp, cassava flour, hot sauce, lemon juice and zest, and south Louisiana seasonings are all you need to make Authentic Cajun Fried Shrimp at home.

Grab the shrimp and the seasonings:

Shrimp and south Louisiana seasonings in bowls. — Seasoning the shrimp for just a few minutes injects the finished seafood with just the right amount of spice and heat.

And pour the hot sauce, citrus and south Louisiana spices right over the shrimp:

Seasonings on top of raw seafood. — Just pour the seasonings right on top of the shrimp.

Then, coat the shrimp with the mixture. I like to use my hands to really get as much seasoning as I can on the shrimp:

Let the oil in your cast iron skillet heat up to 350 degrees F. While that's going, get two shallow bowls or plates out. Beat the eggs lightly in one bowl, then pour the cassava flour into the other bowl or plate:

When the oil is ready, start dipping the shrimp in the egg wash:

Now, press the shrimp into the flour, turning a few times to coat, then shaking off the excess:

Finally, fry in small batches until all of the Cajun fried shrimp are golden brown and cooked throughout. A digital thermometer inserted into the thickest part of the shrimp should read at least 145 degrees F before you transfer it to a paper towel-lined plate.
