This was so easy. I have never made mac&cheese in the instant pot before and this will be my new go-to.
I happened to have leftover sautéed onion and garlic in the fridge and added that to the pasta water, (could have added even more:).
Added about 1 cup cubed American pasteurized cheese (Velveeta) as well as the 2 cups shredded (cheddar, provolone, mozzarella mix). I added 1 cup of milk and did not add any other liquid.
It turned out fantastic! It is creamy, cheesy and the pasta is perfectly cooked.
