Follow the same ingredient list from above BUT only use 1/4 cup milk and NO flour.
In your instant pot, add 2 cups macaroni noodles, 2.5 cups of water, salt, pepper, ground mustard, garlic, and Worcestershire sauce.
Close the lid of the instant pot and set to manual for 6 minutes. Once the noodles have cooked, immediately use a quick pressure release to release the steam. Open the lid.
There will be extra water in your Instant Pot. That is okay! Add 1/4 cup milk and 4 oz of Velveeta cheese into the pot. Stir until the cheese melts.
Then, add the mozzarella and cheddar cheese into the pot, along with the rest of the Velveeta. Stir again until all of the cheese has melted. Add a little more milk if you like your macaroni and cheese a thinner consistency
Finish by mixing in the parmesan cheese.
