Believe it or not, making boxed macaroni and cheese is even easier in the Instant Pot!  No need to drain or babysit the pasta while it cooks and everything simply mixes together in one pot.  While making macaroni and cheese from scratch is the best.  We keep a few boxes of Annie’s Macaroni and Cheese on hand for when we need a quicker version.  

What is so great about Instant Pot Boxed Macaroni & Cheese?

The biggest advantage of using the Instant Pot for an already easy process is that you simply combine everything and walk away. No waiting for the water to boil, stir your pasta, or babysit it while it cooks.  There is also no need to drain the pasta after it cooks.

After you quick release the pressure, you add a little butter to loosen up the noodles.  Then add your cheese powder and a little milk and it’s that simple.  You can use the heat from the instant pot or turn it on sauté function for a couple minutes if your sauce is too thin.
