I start by bringing a large pot of salted water to a boil. Once boiling, I add the pasta and cook it according to the package instructions until al dente. After draining, I reserve a bit of the pasta water to adjust the sauce later.
While the pasta cooks, I heat olive oil in a large skillet over medium heat. I add the minced garlic and sauté it until fragrant, about 1–2 minutes, making sure it doesn’t burn.
Next, I toss in the fresh spinach. It wilts quickly, so I stir it for just a few minutes until tender but still bright green. This step keeps the flavors fresh and vibrant.
I add the lemon zest, lemon juice, salt, pepper, and red pepper flakes. I stir everything together to combine the flavors. The lemon lifts the dish and gives it a refreshing zing.
I add the drained pasta to the skillet and toss it with the spinach and garlic mixture. If it seems dry, I add a splash of reserved pasta water. Finally, I sprinkle freshly grated Parmesan on top.
I plate the pasta while it’s hot, making sure each serving gets a little extra cheese and a touch of lemon zest. It’s ready to enjoy immediately!
