Ingredients

Units Scale

Cajun Seasoning 

  • 1 tbsp Black Pepper
  • 1 tbsp Paprika
  • 1 tsp Garlic Powder
  • 1/2 tsp Onion Powder
  • 1/2 tsp Cayenne Pepper
  • 1/2 tsp Thyme Leaves
  • 1/2 tsp Salt

Cajun Sauce

  • 2 tbsp Unsalted Butter
  • 2 tbsp Flour
  • 1 tbsp Cajun Seasoning
  • 1/8 tsp Salt
  • 1 cup Milk
  • 1/4 cup Parmesan Cheese
  • 2–4 tbsp Water (if needed)

Instructions

  1. In a small spice jar or mason jar, combine all the spices for the Cajun seasoning blend. Add a lid and shake to combine and set aside.
  2. In a large saucepan, melt 2 tablespoons of butter over medium-low heat.
  3. Once the butter is completely melted, reduce the heat and slowly mix in the flour stirring constantly. This should yield a smooth paste like texture. This is your roux.
  4. Then slowly whisk in the Cajun seasoning and the salt. This will create a thick red orange paste.
  5. Slowly pour in the milk stirring continuously. Increase the heat to medium still stirring until the buttery Cajun roux combines completely with the milk. About a minute or two. Make sure the roux is not sitting on the bottom of the saucepan or it will burn.
  6. Add the cheese a little at a time stirring until combined. Again make sure the cheese isn’t settling to the bottom and burning.
  7. Simmer on medium-low heat for about 5 minutes stirring occasionally. DO NOT allow the sauce to boil. The sauce will thicken as it cooks.
  8. Add a tablespoon of water at a time if the sauce needs thinning out until desired consistency is reached. If you are making this sauce for pasta, reserve a 1/4 cup of pasta water for this.

Notes

Note, you will have leftover Cajun spice mix which can be used to season chicken breast or shrimp to add to your pasta dish.
