Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until tender but still firm to the bite, stirring occasionally, about 8 to 10 minutes. Drain pasta, reserving 1 cup of the pasta water.
Place the hot pasta in a large bowl. Add the tomatoes, olive oil, lemon zest and juice, ricotta salata cheese, salt, pepper, and 1/2 cup of the pasta water. Toss to combine, adding the remaining pasta water, if desired. Serve.
