Bring a large pot of water to a boil and cook the pasta according to the package.
Meanwhile, in a large bowl, mix together the capers, lemon zest, lemon juice, olive oil, parmesan cheese, basil, parsley, garlic powder, salt, and pepper.
Once the spaghetti is al dente, add it to the same bowl as the lemon sauce and mix together. Finish with a drizzle of olive oil and serve.
