The Players for this Cajun Shrimp Sauce Recipe

Ingredients:

• Shrimp – You’ll need about a pound and a half of deveined and rinsed raw shrimp.  The shrimp will be cooked in the Cajun sauce!
• Butter – For this recipe, you’ll need 3 tbsp butter, but you can use olive oil if you prefer.
• Shallot – Using shallots in this recipe gives a more delicate, sweet flavor to our delicious sauce. You can also use an onion or onion powder if you’d like.
• Garlic – You’ll need 4 cloves of garlic for this recipe or you can use garlic powder, 
• Flour – To make our sauce thick and creamy, we’ll need a little bit of white flour to create a roux.
• Vegetable Broth – You’ll need some vegetable broth for this recipe.  Alternatively, you can use chicken broth or seafood stock if you’d like!
• Tomato Paste – You won’t need much tomato paste for this recipe, so freeze the remaining in tablespoonfuls on wax paper and move to a freezer bag for later use!
• Worcestershire Sauce – Adding a splash of Worcestershire sauce will give our sauce a savory element.
• Cajun Seasoning – To make our Cajun cream sauce, you’ll need lots of Cajun seasoning.  If you prefer to make your own seasoning, head to down to the bottom of the post for a quick recipe.
• Paprika – Paprika will give a more mild flavor to the sauce.
• Red Pepper Flakes – To make this a spicy Cajun shrimp sauce, add as little, or as much, red pepper flakes as you’d like!
• Salt and Pepper – Season with salt and black pepper to taste.
• Heavy Cream – To make our Cajun creamy sauce, you’ll need some heavy cream.
• Parmesan Cheese – Adding Parmesan cheese will give a nice saltiness and cheesiness to our sauce.  

Tools:

• Skillet – You’ll need a large skillet to make this Cajun shrimp sauce recipe. I also use a large skillet to make my Easy Shrimp Scampi with Linguine Recipe.

How to make Creamy Cajun Shrimp Sauce Recipe

In a large skillet over low heat, melt butter or warm up olive oil if using. To the melted butter, add your diced shallots and saute for 2 minutes.  Add in your minced garlic and cook for 30 seconds, taking care not to burn fresh garlic if using.

To your shallots and garlic, sprinkle in your flour and cook the flour for 2 minutes. Add in your vegetable broth and whisk well, breaking up any lumps that may have formed from the flour.  Whisk until smooth.

Add in your tomato paste, Worcestershire sauce, and all of the seasonings, and allow the mixture to come up to a simmer for 5 minutes.  

To your Cajun sauce, pour in the heavy cream and your grated Parmesan cheese.  Allow the mixture to come back up to a simmer, and once it begins simmering, add in your uncooked shrimp, stirring occasionally.  Note: I found a Cajun cheese at my local ALDI, so subbed that for Parmesan and it was delicious!

The shrimp should take only 5-6 minutes to cook completely.  Serve on top of penne pasta or rice and top with additional hot sauce and chopped green onions.  

Homemade Cajun Seasoning Recipe

You can make your own simple homemade seasoning with ingredients you might already have on hand!  This recipe will make 2 tablespoons of Cajun seasoning:

Storage and Reheating Instructions

Place any leftover cajun shrimp sauce in an airtight container and place it in the fridge.  It will keep in the fridge for up to 3 days. To reheat, place your shrimp on a microwave-safe plate and reheat in the microwave for 2-3 minutes on 50% power until heated through.
