Boil a large pot of salted water and cook the fettuccine according to package instructions until al dente.

In a separate saucepan, melt the butter over medium heat.

Add the heavy cream to the melted butter and stir to combine.

Simmer the mixture for about 5 minutes, allowing it to thicken slightly.

Gradually whisk in the grated Parmesan cheese until fully melted and smooth.

Season the sauce with salt and pepper to taste.

Drain the cooked fettuccine and add it to the sauce, tossing to coat evenly.

Cook for an additional minute, allowing the pasta to absorb some sauce.

Serve hot, garnished with chopped parsley.

Enjoy your delicious homemade Alfredo pasta!
