Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente.

Reserve 1 cup of pasta water, then drain the pasta in a colander.

In a large skillet, heat olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.

Reduce heat to low, then add the softened cream cheese and reserved pasta water. Stir until the cream cheese is melted and the sauce is smooth.

Season with salt and black pepper to taste.

Add the drained pasta to the skillet and toss to coat in the sauce. If the sauce is too thick, add more pasta water as needed.

Serve immediately, garnished with chopped parsley.
