  • 12 to 16 ounces fettuccine or substitute with your favorite pasta type
  • 1 ¼ cup heavy whipping cream; divided
  • 2 tablespoons butter
  • 1 ¼ cup finely grated parmesan cheese Romano cheese, or a combination of both; reserve ¼ cup for garnish
  • ½ cup pasta cooking water
  • Salt and Pepper to taste


  • Bring 1 cup heavy cream and 2 tablespoons butter to a simmer over medium heat. Reduce heat to medium low and let simmer for 12-15 minutes, stirring occasionally and until reduced slightly. Be careful not to let the cream scorch!
  • While cream simmers, cook pasta in heavily salted water according to package directions to al dente, or desired tenderness.
  • When the cream is reduced, remove from heat. Add ¼ cup reserved heavy cream and 1 cup grated parmesan cheese. Stir until the sauce is smooth. Add salt and pepper to taste.
  • When pasta is cooked, use a measuring cup to reserve ½ cup of the pasta water, set aside.
  • Drain pasta (don’t rinse) then immediately put into a large serving bowl (you want the noodles to be slightly wet).
  • Pour the Alfredo sauce over the pasta tossing to coat all the noodles. Add a few splashes of reserved pasta water (you won't use use all of it) until desired consistency is reached. Top with reserved parmesan cheese. Serve immediately.
  • Sauce will continue to thicken as it cools so add a few more splashes of pasta water to bowl if needed to loosen the sauce.


  • Don't boil the heavy cream, just let it simmer down nice and easy. You want to see some bubbles around the edges and some steam rising from the pan.
  • Be sure to salt the pasta water quite generously. I prefer kosher salt and use about 1-2 tablespoons. If you're using table salt, reduce to 1.2 to 1 tablespoon.
  • Don't forget to reserve ½  cup of the pasta water after the pasta has been cooked. Scoop some out using a measuring cup. If you forget it's totally okay. I've forgotten on several occasions and it's still delicious.
  • If you want your dish to be more saucy, use less pasta. I think the sweet spot lies somewhere between 12 and 16 ounces. I usually make 16 ounces of pasta (one pound).
  • Try different types of pasta. If I'm adding chicken or shrimp, I like to use farfalle (bowties) or penne.
  • If you want to add garlic, crush two cloves with the back of a knife and simmer it along with the heavy cream. Remove from sauce before adding the parmesan cheese.
  • A pinch of fresh nutmeg is common in Alfredo sauce, but is totally optional. If you'd like to try it, add it to the sauce after you've stirred in the cheese.
  • Store leftovers in the refrigerator. You can reheat by microwaving at 50% power or on the stovetop over low heat, stirring gently with a silicone spatula.
