Fill a large pot with water and add salt. Bring to a boil. Cook fettuccine according to package instructions.

Once the pasta becomes tender, drain it using a colander. Reserve a small cup of pasta water for later use.

Place a large skillet over medium heat. Add butter and let it melt slowly until it becomes smooth.

Add minced garlic to the melted butter. Cook for one minute while stirring gently to release the aroma.

Pour heavy cream into the skillet. Stir well and let the mixture simmer gently for about three minutes.

Add salt, black pepper and optional nutmeg. Stir well to combine all flavors in the creamy sauce.

Slowly add grated parmesan cheese into the sauce. Stir constantly until the cheese melts and the sauce thickens.

Place the cooked fettuccine into the sauce. Toss gently so every strand becomes coated in creamy Alfredo sauce.

If the sauce is too thick, add a little reserved pasta water. Stir until the sauce becomes smooth.

Taste the pasta and adjust seasoning if needed. Add more cheese or pepper according to preference.

Sprinkle chopped parsley on top for freshness and color. This also adds a light herbal flavor.

Serve the pasta warm in bowls. Enjoy this creamy comfort dish with family or guests.
