Learn how to make easily a Baked Macaroni and Cheese recipe in Instant Pot. Pasta and cheese casseroles are known since 14th century. Every country in the world including Italy, England, USA and Canada consider Mac and Cheese its own national dish. The third US president Thomas Jefferson fell in love with this delicious dish. He tried to re-invent a machine for extruding pasta. As the story goes, he didn't succeed much at this process, so he decided to start importing both macaroni and Parmesan cheese. In 1802, Jefferson served "a pie called macaroni" at a state dinner. So this is the official birth of homemade Mac and Cheese in the USA. Later on Kraft made it part the American life by adding the Old Cheddar Cheese.
