Bring a large pasta pan of water to the boil.

When the water is boiling add 3 tablespoons of salt.

Add the fettuccine and cook for 5 minutes, stirring occasionally.

Whilst the pasta is cooking, melt your butter in a medium sized bowl and add the parmesan.

Mix until the cheese almost dissolves, and forms a smooth cream, about 3-4 minutes.

Drain the pasta leaving just a small amount of water and toss the fettuccine with the Alfredo sauce.

If you're a real cheese lover serve with extra parmesan grated on top.
