In a large pot, combine the egg noodles, water, 2 tablespoons of butter, minced garlic, salt, and black pepper.
Bring the mixture to a boil over medium-high heat, stirring occasionally to prevent the noodles from sticking.
Reduce the heat to medium and simmer, stirring frequently, until the noodles are tender and most of the water has been absorbed, about 10 to 12 minutes.
Remove the pot from heat and stir in the remaining 2 tablespoons of butter until melted and well combined.
Add the grated Parmesan cheese and stir until the cheese is fully melted and the noodles are creamy.
Sprinkle the chopped fresh parsley over the noodles and toss gently to combine.
Serve immediately while warm.
