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 the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.

Stir in the lemon juice, lemon zest, salt, and pepper. Cook for 2-3 minutes to combine the flavors.

Add the drained pasta to the skillet and toss to coat in the sauce. If the sauce is too thick, add reserved pasta water a little at a time until desired consistency is reached.

Remove from heat and stir in the grated parmesan cheese.

Serve immediately, garnished with chopped parsley.
