IS THIS A REALLY SPICY SAUCE?
This recipe yields a nice medium spicy level. You can easily make this spicier by adding more Cajun seasoning or milder with using less.
WHAT IS THE BEST CHEESE TO USE FOR THIS RECIPE?
Freshly shredded parmesan cheese will melt the best if you have time to do that yourself.
Otherwise you can use canned parmesan, or the shredded parmesan that comes in the plastic containers.
HOW TO THICKEN/THIN THIS ALFREDO SAUCE:
While this sauce will thicken on its own, especially with the addition of the cream cheese in the recipe which really gives it a nice and creamy texture.
You can also add some more parmesan cheese, you can never go wrong with more cheese.
Alternatively if you want the sauce a little thinner then add a few Tablespoons of heavy cream at a time until you reach your desired consistency.
WHAT ARE DIFFERENT WAYS TO SERVE THIS SAUCE?
While a lot of people thing that making pasta sauce is that you just serve it over past, there is much more to do with it than that. Some of my favorites include:
- Dip for breadsticks and garlic bread
- Using in a baked casserole especially served with chicken or andouille sausage
- Lasagna Rolls
- Lasagna
- Served over vegetables
- As a sauce on pizza
HOW TO STORE:
This sauce can be stored in an airtight container in the refrigerator where it will keep for up to 4-5 days.
You can also freeze this sauce, place in a freezer bag and press out any air that remains in the bag. This will keep for up to 3 months in the freezer.
To defrost, remove to the refrigerator until thawed. To reheat, place in a pan and slowly heat up on the stove, if needed to thin out add a little bit more cream to the mixture.
TIPS AND TRICKS:
- Using full-fat cream cheese is best for the flavor and richness of this sauce.
- If you use salted butter, you may want to consider using an unsalted Cajun seasoning or your sauce will be pretty salty.
- This can be frozen, see above on how to do that.
- You can use this in other ways that just serving over pasta, see above on ideas.

I’m sorry that this came out too salty for you. Sometimes people have a lower salt tolerance and also the brand of cajun seasoning can make a difference. I will update the recipe to start with a lesser amount and add and taste along the way for personal preference.
