This Italian dish comes together with mostly pantry staples.
In a large pot of boiling salted water, cook pasta until al dente. Reserve 1/2 cup pasta water; drain pasta, and return to pot. Add butter, 1/4 cup Parmesan, and 1/4 cup pasta water; toss to combine.
Add artichokes, tomatoes, parsley, and, if necessary, enough remaining pasta water to create a thin sauce that coats pasta; season with salt and pepper. Top with remaining 1/4 cup Parmesan, and serve immediately.
