Wash the parsley and let it dry. Peel fresh or defrosted shrimp if needed. Marinate the shrimp with finely chopped garlic and parsley. Add half of the olive oil, salt, and pepper. Put it in the fridge for at least half an hour to marinate (ideally a few hours or overnight).
Prepare zucchini. If you are using fresh pasta that takes only a few minutes to cook, then slice and fry zucchini in advance.
Heat the remaining olive oil over medium heat in a large pan. Add the sliced zucchini and cook for 1-2 minutes or more on each side until lightly browned and fully cooked. Season with salt and pepper
Bring a pot of salted water to boil for the pasta. Always opt for a larger-sized pot while cooking pasta to make sure it has enough room in the water, and add enough salt to the water as if you would put in a soup.
Add the marinated shrimp to the pan with zucchini and cook until they change color to pink and are cooked through.
Stir in the cream. Add 1 Tbls of cheese. Adjust salt and pepper to taste and lower the heat.
Before draining the pasta, preserve a cup of paste water and set aside.
Drain the pasta and add it to the pan with the sauce, stirring until well combined. Adjust the sauce thickness by adding preserved water if needed.
To serve, sprinkle freshly grated Parmesan cheese and black pepper over the pasta and garnish with optional fresh parsley for a vibrant finish.
