This classic fettuccine Alfredo is made with cream, butter, Parmesan cheese, and parsley. It's a pasta comfort food at its finest, and an Italian dish made with just a few basic ingredients that most home cooks are likely to have on hand.

As with any recipe that has few ingredients, it is important that each one is fresh and of the best quality you can get. Make sure you use freshly grated Parmesan cheese—the kind you buy in a block and grate yourself, not the kind from a can.

You also want to use fresh parsley and not dried, if possible. For a special treat, buy fresh fettuccine instead of using dried pasta from a box—or make your own homemade pasta. Fettuccine is a fresh pasta that's not hard to make.

Tip

When making cream-based sauces, you might be tempted to substitute milk or half and half for the heavy cream, but these ingredients do no behave the same way in the pan. Milk and half-and-half will curdle when simmered, but heavy cream is more stable, which is why it's the choice for cream sauces.

How to Store and Freeze Fettuccine Alfredo

Fettuccine Alfredo will keep covered in the refrigerator for 3 to 5 days. If you would like to freeze this dish, it's advised to undercook the pasta slightly. This way, when you freeze and reheat it, the pasta will be tender and not mushy.

Recipe Variations

  • You can make fettuccine Alfredo even more special by adding protein or vegetables. Some grilled chicken, sliced into strips, is great, and so is cooked shrimp.
  • For a vegetarian Alfredo, toss in some sautéed mushrooms or steamed asparagus. Peas, broccoli, and/or sliced green onion tops are also a nice addition to any versions of fettuccine Alfredo.
  • If you are eating vegan, there are a few ways to alter this recipe to accommodate your needs, whether you use a dairy-free roux in place of the cheese or tofu and vegan cream cheese.
  • Saute 2 to 3 cloves of garlic, minced, in half of the butter for about 2 minutes. Add to the cream along with the remaining butter pieces and continue with the recipe.
  • Make it a spicy chicken Alfredo. Slice 4 chicken tenderloins into small pieces. Brown the chicken in a small amount of vegetable oil or butter in a skillet. Sprinkle with seasoned salt or Cajun or Creole seasoning. Toss the cooked chicken with the fettuccine and sauce.
