Instant Pot Kraft mac and cheese is insanely quick and easy to make. With just a 4 minute cook time, you will have have dinner on the table in next to no time.

Pressure cooker mac n cheese is one of my favorite ‘I can’t be bothered to cook’ dinners (another is this air fryer frozen pizza). I also have a great recipe for 1 pot homemade mac and cheese if you prefer a more traditional version.
Cooking macaroni cheese in a pressure cooker means minimal prep and cook time, and is very low effort (no straining required). The perfect comfort food.
My favorite brand to use is Kraft blue box, but other brands of boxed macaroni like Annie’s, Trader Joe’s, or Velveeta mac and cheese will also work.

Cooking boxed macaroni cheese in an Instant Pot

1 – Add butter to the instant pot first, and use it to grease the bottom of the pan. This will help to prevent the macaroni from sticking as it cooks. You can use margarine as per packet instructions, but I think butter adds more flavor (especially since this recipe skips the milk).
2 – Then add in two cups of water, and gently pour the Kraft macaroni on top. Spread out the macaroni noodles so they are all covered by the water, but do not stir it.
3 – Place lid on and ensure the valve is in the sealing position. Pressure cook on high for 4 minutes. Use quick release and open the instant pot – don’t leave it to release naturally as this will lead to overcooked macaroni.
4 – Add in the contents of the cheese packet and some shredded cheese to make the cheese sauce. Adding extra cheese is optional, but really improves the flavor (sharp cheddar cheese is best!).
Stir until well combined. You can add a splash of milk or water if the sauce becomes too dry.

In the unlikely event of any leftovers, store in the fridge within two hours of cooking, and consume within 3 days.
