Bring a large pot of salted water to a boil. Cook the pasta according to the package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, melt the butter. Add the minced garlic and sauté for 1–2 minutes until fragrant.
Stir in the heavy cream and bring it to a gentle simmer. Let it cook for 3–4 minutes, stirring occasionally.
Add lemon zest and juice, then toss in the grated Parmesan cheese. Stir until the cheese melts into the sauce.
Season with salt and black pepper to taste.
Add the cooked pasta to the skillet and toss to coat in the creamy sauce.
Serve warm, topped with a sprinkle of parsley if you’re feeling fancy.
