Cajun Alfredo Sauce, a great homemade alfredo sauce for the best dinner such as Cajun Chicken Alfredo or Cajun Shrimp Alfredo! This simple easy creamy sauce is full of cheese, Cajun seasoning, peppers, and onions. Add some pasta and chicken or shrimp, for a full meal!
People seem to be loving my Homemade Alfredo Sauce and Alfredo Sauce with Cream Cheese so thought I’d add this Cajun Alfredo Sauce! You can add your favorite pasta (or low carb option like zucchini noodles), a protein (chicken, shrimp or even sausage would be great), and your favorite other vegetables for an easy and delicious meal.
Tips for Making the Best Alfredo Sauce
- Use the best quality Parmesan cheese you can find and grate it yourself. It will melt better and you will be much happier with the results
- Use heavy cream. It will result in a much creamier and thicker sauce than a lower fat alternative
- Slowly add the cream and be sure it is hot before stirring in the Parmesan cheese
- Add your other ingredients such as vegetables, herbs, and proteins at the very end
- Cajun seasoning can vary a lot between brands, so add a little at a time
How to Make Cajun Alfredo Sauce
