Notes
Watch the Video Recipe – For a better understanding of the recipe, I recommend watching the step-by-step video tutorial. It will guide you through the cooking, and texture of the sauce to help you achieve the best results.
Check the FAQs – If you have any questions about ingredient substitutions, cooking methods, or storage tips, be sure to check the FAQs section located under the recipe card.
Make-Ahead & Storage Tips – Alfredo sauce is not ideal to make-ahead, so it's recommended to be done just before serving. Store leftovers in an airtight container in the fridge for up to 3 days.
Can I Use Different Cheese? – You can use Parmesan cheese, or Pecorino Romano cheese for this recipe, to achieve the best flavor and result.
Do I need cream in Alfredo sauce? - No, the authentic recipe is made with just 3 ingredients: pasta, butter and parmesan.
Don't forget the pasta water. Pasta water is full of starch released by the pasta and it's essential to make a creamy sauce.
Work quickly. Butter hardens quickly even at room temperature, so work while the pasta is still hot and serve immediately on warmed plates to keep the sauce creamy.
