In a large pot, bring salted water to a rolling boil. Add your pasta and cook according to package instructions. In the last 2-3 minutes of cooking, add the broccoli florets to the pot. Once done, drain the pasta and broccoli, reserving 1/2 cup of the pasta cooking water, and set aside.
In a large skillet, heat the olive oil over medium heat until shimmering but not smoking.
Add the minced garlic to the skillet and sauté for approximately 30 seconds, stirring frequently to prevent burning until the garlic is fragrant and golden.
If you like a bit of heat, add the red pepper flakes and sauté for an additional 10 seconds to combine the flavors.
Introduce the drained pasta and broccoli to the skillet, tossing well to coat the ingredients in the garlic-infused olive oil.
Drizzle in the freshly squeezed lemon juice and sprinkle the lemon zest over the pasta. Toss everything together, adding some reserved pasta water gradually, until you achieve your desired creamy consistency.
Season the dish with salt and freshly ground black pepper, thoroughly mixing to ensure each bite is flavorful.
Plate the pasta immediately. Generously top with freshly grated Parmesan cheese, and finish with a sprinkle of chopped parsley for a bright touch.
Notes
Serve in warm bowls with an extra drizzle of olive oil and lemon zest for visual appeal.
