Easy Authentic Alfredo Sauce, Made Easy

Now, let’s get to the heart of the matter—making your Easy Authentic Alfredo Sauce. Follow these simple steps for a creamy, delicious result.
Step 1: Cook the Fettuccine
Bring a large pot of salted water to a boil. Add the fettuccine pasta and cook according to package instructions until al dente. Reserve about 1 cup of the starchy pasta water, then drain the pasta.
Step 2: Prepare the Sauce
In a skillet or saucepan over medium heat, melt the unsalted butter. Allow it to bubble gently, but do not let it brown. This will create a smooth base for your sauce.
Step 3: Combine Ingredients
Once the butter has melted, add the reserved starchy pasta water to the skillet. Stir to combine, then gradually add in 1 cup of the freshly grated Parmesan cheese, whisking continuously until the cheese has melted and the sauce is smooth.
Step 4: Season
Taste the sauce and season with kosher salt and freshly ground black pepper to your liking. Remember, the cheese is salty, so start with a little salt and adjust as needed.
Step 5: Toss the Pasta
Add the drained fettuccine to the skillet with the sauce. Toss the pasta in the sauce until it is fully coated. If the sauce is too thick, you can add a bit more pasta water, a tablespoon at a time, until you reach your desired consistency.
Step 6: Serve
Remove the skillet from heat and serve immediately. Garnish with additional Parmesan cheese and chopped fresh Italian parsley for a pop of color and flavor.
