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

Drain the pasta in a colander and set aside.

In a skillet over medium heat, melt the butter. Add the minced garlic and sauté for about 1 minute until fragrant.

Stir in the lemon juice, lemon zest, salt, and pepper.

Add the cooked pasta to the skillet and toss to coat evenly with the sauce.

Sprinkle with grated parmesan cheese and mix well.

Garnish with chopped parsley and serve warm.
