Step 1: Bring a large pot of heavily salted water to a boil. Cook the pasta according to package directions until just under al dente.
Step 2: While the pasta is cooking, whisk together the olive oil, lemon juice, lemon zest, minced garlic, and red pepper flakes in a large mixing bowl.
Step 3: Before draining the pasta, reserve approximately 1 cup of the starchy pasta water.
Step 4: Drain the pasta and immediately add it to the bowl with the lemon and oil mixture. Toss vigorously to coat.
Step 5: Add the halved cherry tomatoes, fresh basil, and parsley. If the pasta seems too dry, add the reserved pasta water a tablespoon at a time until a light sauce forms.
Step 6: Season with salt and pepper. Garnish with Parmesan cheese if desired and serve immediately or at room temperature.
