Skip the boxed stuff and make this creamy homemade shells and cheese in your Instant Pot. It's perfect for busy weeknight when you want a quick one-pot dish with minimal prep and cleanup.
Start by adding your pasta shells, water, salt, butter and squirt of mustard into your Instant Pot and stir.
Seal the lid and cook on high pressure for 5 minutes.
When the 5 minutes are up, let it naturally release for 10 minutes, then manually release any remaining pressure (see tip below).
Stir the pasta, (it will look watery), add the evaporated milk and stir again.
Gradually add in the shredded cheese in handfuls and stir constantly until the cheese has melted.
Adjust the seasoning if needed (salt and garlic powder). It will thicken as it sets.
This makes a very creamy and soft mac and cheese as we like our pasta soft, however if you want your pasta to be more al dente, then do a quick release instead of a natural release.
Notes
Variations:
You can change up your cheese by adding in some Monterey Jack with your sharp cheese. You can also add some mozzarella (if you want a cheese pull), or some Pepper Jack cheese for a little extra spice.
Add in some protein like ham, bacon, or shredded rotisserie chicken.
Love spice? Try adding in a little hot sauce or cayenne.
Mix in some broccoli or peas to add in some veggies.
Helpful Tips:
Make sure to add your cheese gradually or it can turn grainy.
Use freshly shredded cheese instead of the packaged pre-shredded cheese as it melts better.
Storage:
Store your leftovers in the fridge for 3-4 days in an airtight container.
