Bring large pot of salted water to a boil. Add spaghetti and cook per package instructions.
While your pasta is cooking, place shrimp, shell side down, in an oven proof casserole dish and broil in oven for approximately 3-5 minutes or until cooked through.
Remove shrimp from oven. Strain pasta and place into casserole dish.
Drizzle generously with olive oil and top with fresh parsley, lemon zest and cracked pepper and salt to taste.
