Instant Pot Mac and Cheese

Mac and cheese is incredibly easy to make in the Instant Pot and there’s no draining required! It is a one-pot process and it’s so easy to clean up.

The pasta absorbs the water and leaves very little behind. In fact, just enough to help make your cheeses creamy when adding it.

Pre-shredded cheese such as the kind that comes prepackaged contains cellulose and can make mac and cheese stringy or even gritty.

It’s best to opt for block cheese that you can cut up yourself and add to the pot to meltdown. This type of cheese doesn’t have any additives that prevent clumping.

This Irish Mac and Cheese is made with Dubliner cheese which is similar to cheddar. The main difference in cheeses is that Dubliner cheese has a delicious nutty flavor and has a wonderful balance of sweet and sharp flavors.

Dubliner makes an incredibly delicious mac and cheese but if you can’t find it, a sharp cheddar cheese is a good substitute.

As mentioned above, it’s a good idea to use block cheese when making mac and cheese to get the creamiest and smoothest texture. Dubliner cheese comes in a block and that makes it perfect for making this Irish Mac and cheese.

Mozzarella is added to this mac and cheese for a very creamy texture but the main flavor of this Instant Pot Mac and Cheese is the Dubliner cheese!

How To Make Instant Pot Irish Mac and Cheese

The steps to make this mac and cheese are very few and it’s very easy to do.

The first step to making this Instant Pot mac and cheese is to cook the bacon and set it aside to allow it to cool. Once it is cool, crumble the bacon and save as a garnishment.

The elbow pasta is added to the inner liner of the Instant Pot and the four cups of water is added to the pot. The pasta is then pressed down into the pot to ensure that it is completely submerged.

The salt, pepper, and cayenne are then sprinkled into the pot, and the Dijon mustard and hot sauce are also added in.

The lid is closed and the pressure cooker is set to 4 minutes on MANUAL/PRESSURE COOK. Once the four minutes are up, a quick release is performed carefully and intermittently. If you do a quick release all at once, the water will spew out of the venting valve and make a mess. Slowly releasing pressure is the way to go for this recipe.

Refer to your user manual for your pressure cooker for how to safely perform a quick release.

Once the pressure has been released, the lid is removed and the pot is to SAUTE. Once on sauté, the chopped Dubliner and Mozzarella cheese is then stirred in to melt.

TIP: While the mac and cheese is being pressure cooked, heat a skillet on the stove and add the panko crumbs with the garlic. Lightly toast the panko crumbs and remove them from the heat.

When it is time to serve, top with the toasted panko crumbs and crumbled bacon.
