This ultra low-carb, one-pan Keto Cajun Shrimp recipe has about 1 net carb per serving! You only need one pan and 20 minutes to create an easy low-carb dinner.

I don’t know what I love more about this recipe — the actual Cajun shrimp or the Cajun cream sauce for the shrimp. Regardless, this is a super simple recipe that takes about 20 minutes to make from start to finish. 

I used a homemade Cajun shrimp seasoning to make this recipe since I know that not everyone keeps the pre-made kind on hand. Cajun shrimp seasoning is a blend of of paprika, Italian seasoning, onion powder, garlic powder, and red pepper flakes. Simple! 

Enjoy the low-carb Cajun shrimp right away, or meal prep for later in the week. Whenever you eat the shrimp in Cajun cream sauce, I know you’re going to love it!

Ingredients in Cajun Shrimp

What I love most about this recipe — aside from how quickly it comes together — is that I always have these ingredients on hand.

The ingredients for this Cajun shrimp recipe are mostly pantry staples you probably already have. Since shrimp is handy to keep in the freezer, you’ll find this is a go-to recipe for busy nights! 

Here’s what you’ll need to make the shrimp, seasoning, and the Cajun sauce for the shrimp:

• Shrimp
• Butter
• Garlic
• Spices
• Heavy cream

Is Shrimp Keto? 

Yes! Shrimp is a great source of keto-friendly protein. It’s low in carbs but high in protein! 

How to Make Cajun Shrimp

1. Begin by heating a large heavy bottom skillet over medium heat. I prefer to use my cast iron skillet.
2. Melt butter in the skillet and add the garlic, shrimp and spices. Stir well to make sure the spices are evenly distributed and the shrimp is covered.
3. After 3-4 minutes, the shrimp will begin to turn pink (however, this will depend on how big your shrimp are). Add the additional butter and heavy cream.
4. Cover and reduce the heat to low. Allow the butter to melt completely and a creamy Cajun sauce will develop.
5. Stir the shrimp very well so it’s completely coated and serve immediately. If you wish, you can garnish with fresh lemons, parmesan cheese, or hot sauce.

Can This Recipe Be Meal Prepped? 

Yes, this dish would be a great way to prepare a healthy protein that could be used for multiple meals throughout the week!

Need to speed up dinners during a busy week? Double this recipe on your prep day and then throw together shrimp and grits (maybe even this keto version) or Cajun shrimp tostados or maybe some tacos.

How Many Net Carbs Are in This Recipe? 

This recipe has about as close to zero net carbs as you can possibly get! For one serving of this keto Cajun shrimp, there are about 1 net carb per serving.

This is the kind of dish you can pair with a side that is slightly higher in carbs than you might normally choose. 

How to Store and Reheat Cajun Shrimp

Cajun Shrimp should be stored in the refrigerator in an air-tight container up to four days. To reheat, pour the shrimp and sauce into a skillet and simmer on low until all shrimp are warmed throughout.

You can also microwave in 30-second increments, but be careful to stir often to try to get an even reheat.
