Ingredients
Method
- Place macaroni, water, milk, salt, and mustard powder (if using) in the pressure cooker pot. Stir to combine.
- Secure the lid and cook on high pressure for 5 minutes. Quick-release pressure immediately when time is up.
- Open the lid, add butter and shredded cheese. Stir gently until the cheese is fully melted and the sauce is smooth.
- Spoon into bowls and serve right away with black pepper on top.
Notes
If you prefer an even thicker sauce, let the macaroni sit off the heat for 1 minute after stirring in the cheese—it will continue to firm up. Shredding the cheese from a block gives the smoothest, most velvety sauce.
