Watching the clock, I noticed … in just 18 minutes we went from walking in the door to scooping piping-hot Instant Pot gluten free mac n cheese into everyone’s bowls.  A delicious home-cooked weeknight dinner that uses all real ingredients? Yes please.  I especially love that it’s a one-dish meal, minimizing the amount of dishes made too.

A tradition over from my childhood, we use frozen peas to add a veggie and cool down our mac n cheese.

If you’re feeling fancy,  add an additional 5 minutes under the broiler for a crispy breadcrumb top- still completely doable for a fast meal.

I love this Instant Pot Mac n Cheese for a few reasons:

  1. It’s fast and contained. No more pasta water boiling over onto the stovetop.
  2. It’s truly a one-dish meal.  You don’t even need to dirty a colander!
  3. Because you measure the liquid that cooks the pasta exactly, you can replace some of it with chicken stock and it’ll be absorbed into the pasta.
  4. You control the ingredients. Use the quality and type of cheese that you prefer, your own milk.
  5. It is inexpensive.  As my children have grown, we do occasionally get Annie’s Gluten Free Mac n Cheese, but we end up using 2 full boxes and having no leftovers.  This recipe makes enough for dinner tonight, and a couple thermoses full for lunch tomorrow.

Instant Pot Gluten-Free Mac n Cheese Recipe Notes:

Mac n Cheese is a favorite that can be completely nourishing while still being fast, easy, and inexpensive.  We set the Instant Pot to cook for 4 minutes, but it does take time to come to pressure and for the pressure to release, so allow about 15 minutes to cook the pasta, even though I only listed 4 minutes of cook time.
