This pasta with lemony ricotta, zucchini and arugula is the perfect easy dish to put together, not to mention the light and fresh flavors blend together perfectly!
Bring large pot of water to boil.
In the mean time, in a pan, saute onion in olive oil until about half way cooked, about 3 minutes. Add zucchini, season with salt and pepper and cook until tender- about 10-12 minutes.
At this point, add penne to boiling water.
Add ricotta and lemon zest to the pan with zucchini, and turn heat to low.
When pasta is al dente, reserve 1/2 cup of pasta water.
Drain pasta and add to pan with ricotta and zucchini. Turn heat to medium and add about 1/4 cup of pasta water to make the sauce creamy. You can add more if needed. Add salt and pepper if needed. Add parmesan cheese and stir until combined.
Add arugula and stir all ingredients together in the pan, until they're mixed together well and excess liquid is absorbed.
Plate, season with additional parmesan cheese and enjoy!
