Bring a large pot of salted water to a rolling boil. Add pasta and cook according to package instructions until al dente, about 8-10 minutes.

Heat a skillet over medium heat and melt butter. Add minced garlic and sauté for 1-2 minutes until fragrant.

Reduce heat to low, stir in milk, and gradually add Parmesan cheese while stirring until melted and combined.

Drain the pasta, reserving some pasta water. Add pasta to the skillet and toss to coat. Add reserved water if the sauce is too thick.

Serve immediately, garnished with fresh parsley.
