How Do You Make Jarred Alfredo Sauce Thicker?

Alfredo sauce is a rich and creamy pasta sauce that is loved by many. While you can easily find jarred Alfredo sauce at your local grocery store, sometimes you may find that it’s not as thick as you’d like it to be. Fortunately, there are several simple techniques you can use to thicken jarred Alfredo sauce to your desired consistency.

1. Add Cream Cheese

If you prefer a thicker Alfredo sauce, one easy way to achieve this is by adding cream cheese.

The cream cheese not only adds thickness but also enhances the creaminess of the sauce. To do this, simply melt some cream cheese in a separate pan and gradually whisk it into the jarred Alfredo sauce until well combined. The amount of cream cheese will depend on how thick you want the sauce to be, so start with a small amount and add more if needed.

2. Incorporate Grated Parmesan Cheese

Another method to thicken jarred Alfredo sauce is by incorporating grated Parmesan cheese. Parmesan cheese adds both flavor and thickness to the sauce.

Start by heating the jarred Alfredo sauce in a pan over low heat. Gradually sprinkle in some grated Parmesan cheese, stirring constantly until it melts and thickens the sauce. Be sure to use freshly grated Parmesan for best results.

3. Mix in Cornstarch Slurry

If you’re looking for a quick and effective way to thicken your jarred Alfredo sauce, using a cornstarch slurry can do wonders.

In a separate bowl, mix together equal parts cornstarch and cold water to create a slurry. Stir the slurry into the heated Alfredo sauce and continue cooking over low heat until it thickens to your desired consistency. Keep in mind that cornstarch can alter the flavor of the sauce slightly, so adjust accordingly.

4. Simmer and Reduce

If you have some extra time and want to intensify the flavors of your jarred Alfredo sauce while thickening it, simmering and reducing is a great technique.

Start by pouring the jarred sauce into a pan and bring it to a gentle simmer over low heat. Allow the sauce to simmer for around 10-15 minutes, stirring occasionally, until it reduces and thickens. This method concentrates the flavors of the sauce while giving it a thicker consistency.

5. Add Roux

A roux is a mixture of flour and fat used as a thickening agent in cooking.

To thicken your jarred Alfredo sauce with a roux, start by melting butter in a separate pan over medium heat. Gradually whisk in an equal amount of all-purpose flour until well combined to create a roux. Slowly pour the jarred Alfredo sauce into the roux, stirring constantly until fully incorporated and thickened.


Making your jarred Alfredo sauce thicker is an easy way to enhance its texture and make it more enjoyable. Whether you choose to add cream cheese, grated Parmesan cheese, use a cornstarch slurry, simmer and reduce, or incorporate a roux – these techniques will help you achieve your desired consistency without compromising on taste. Feel free to experiment with these methods and find what works best for you!
