Put the pasta, water, and salt into the Instant Pot. Cook for 4 minutes using the manual function. Quick release the steam so your noodles don’t get overcooked.
Gently stir in the butter until melted. Add the cheese and milk (use 2-3 tablespoons of milk at a time, as needed, up to ½ cup). Add more seasoning or liquid if necessary. For best results, let it sit for 5-10 minutes to let it thicken up a bit. MWAH! Enjoy. It’s so, so good.
