This homemade Alfredo sauce is just as good, if not better, than the Olive Garden original! A rich creamy sauce comes together in under 30 minutes and is ready to coat your favorite pasta.
Once fragrant, whisk in the flour. It will start to thicken.

Notes
Store leftover alfredo sauce covered in the fridge for up to 3 days.
Keep in mind the sauce will continue to thicken as it sits and cools. If it’s not thick enough for you, give it a moment.
Before adding the Parmesan cheese, bring it to room temperature. It will melt faster that way.
I use unsalted butter so I can control the amount of salt I add in. If you plan to use salted butter, keep in mind there is also salt coming from the Parmesan, so taste it before you decide to add more.
Add the pasta to the sauce just before serving. Letting it sit together for too long will cause the pasta to absorb too much of the sauce.
