Today in 1660, a Mr. Isaack B. Fubine was granted a patent, naming him the inventor of Macaroni. That was in the Hague, in Holland.
Macaroni was known before that, but nobody seems to have thought to legalize the topic. So, good for Mr. Fubine.
Macaroni-and-cheese is a different question, and the YIR Research Department has gone to lunch. Sorry; these things happen.
