Back when I had my first baby, my husband’s grandma brought over a big casserole dish full of mac and cheese.
You guys, I was ecstatic. I loved mac and cheese and I was exhausted beyond belief. An already cooked dinner that I knew I was going to enjoy. Yasss.
Then I peeled back the foil to heat it up and I saw all of this weirdness happening in there. To be specific, there was smoked sausage. All up in my macaroni and cheese.
I admit to nothing, but there may have been tears.
I mean, who would ruin mac and cheese that way and then give it to a hormonal new mother?
I decided to just pick around the sausage until my husband convinced me to just grow up and try a bite of the sausage.
Y’all. I am forever in that man’s debt. I’m now hooked on mac and cheese with smoked sausage. Why is it so good? I will never know. But I will always keep eating it and trying to find out.
Anyway, I jumped on the Instant Pot craze, along with the rest of the country, and I figured I’d better learn how to make some pressure cooker mac and cheese. I’ve made this a few times now, experimenting a little each time until I came to this piece of perfection. I started this off with a base recipe I picked up in one of those huge Instant Pot facebook groups, but I’ve changed things up a bit to suit my taste.
I think you’re going to love how this turns out. It’s so creamy and super cheesy. The smoked sausage is divine in here and, in my opinion, switches this over from a side dish to a main dish. Serve with a green salad and you’re good to go.

This was amazing! I was afraid that it was going to be too heavy, but followed the recipe exactly and it was delicious. My kids suggested to maybe add peas on the next batch. Also, if you’re wondering if you should rinse the pot after sauteing the sausage…DON’T. It adds great flavor
Karly says
Peas are a great addition – and I love that your kids suggested them. Mine would never. 😉 Glad you enjoyed the recipe!
Tammy says
This was amazing! My whole family loved it! Definitely a keeper for us.
Karly says
Yay! Glad to hear that!
Amber says
Just half the recipe! 🙂
Leigh says
I have a 3 quart instant pot, are the amounts more in this recipe? Should I cut the amounts in half?
Karly says
I’m not sure how much would fit in a 3 quart. I’ve only ever used a 6 quart.
Jan says
I have all ingredients except evaporated milk……:( any ideas of a decent substitution? I have regular organic milk and heavy whipping cream…….? Thanks~
Karly says
No, I’m sorry, I don’t know of any substitutions. I haven’t tried making this with regular milk or cream, so I’m not sure how well it would work.
Brandy says
We use the Cajun Smoked Sausage with your recipe, it really adds that extra edge to the mac n cheese. Love this recipe!
Karly says
I bet the extra spice is delicious in the mac and cheese! 🙂

My husband travels for work, and our son and I recently had the opportunity to visit him on the road. After working on the road for weeks at a time, it’s safe to say he gets burnt out on eating at restaurants, and after 10-12 hour work days he sure doesn’t feel like grocery shopping and cooking (and I can’t blame him). So on this visit, we brought along our express cooker, and I tried this beauty out! Not only did we get to have a delicious home cooked meal as a family, but he now has leftovers for dinner after we return home! Thanks for this super fast, easy, tasty recipe that allowed us to spend a little more time together.
I may or may not have taste tested throughout the cooking process ?
Karly says
So glad you and your family enjoyed this one and it gave you a little extra time together. My husband travels for work too and it can be rough! <3
Adele says
Since there are many different sizes of Instant Pot, what size is this recipe designed for? I always have trouble with recipes that don’t indicate pot size.
Karly says
I use a 6 quart and have only ever tried this in that.
Adele says
Thanks. I have the 3 Qt so I will half the recipe.
Sara says
What kind of smoked sausage? Like a kielbasa?
Karly says
Yep, kielbasa is perfect.
Christina says
I’ve always wondered about this. Is it 16 oz of cheese before shredding or after?
Karly says
Since it’s a weight measurement, it wouldn’t matter if you measure before or after grating. Certainly easier to measure before though, since cheese is often sold in 8oz blocks. 🙂
Fern says
After a busy Saturday working outside in perfect weather for late October, I came in and looked for something to instant pot using smoked sausage. I came across this recipe. It is fantastic! Very easy to make and great flavor and consistency. Often when I make homemade mac and cheese it is gummy, but not this one. This is a keeper receipe.
Fern says
For those of you wondering if you should invest in an instant pot. The answer is yes. There is just the two of us and unknowingly I bought the 8 quart which is plenty big. I love using it.
Karly says
So glad you enjoyed it, Fern! 🙂
Mistie at Kitchen Ria says
This looks so hearty and delicious, I am going to try it out tonight. I LIVE for Mac n Cheese.
Anna says
Oh my gosh!! You are too funny!! This recipe looks amazing!!! And so easy!! I don’t have an instapot, but I do have a pressure cooker. Can I cook in that?? if so, how long would you recommend?
Karly says
Yes, it should work just the same in any brand of electric pressure cooker.
Maggie says
Wow what an interesting way to use Instant pot! Can’t believe it takes like 10 minutes to cook the whole dish. And plus your mac n’ cheese looks totally perfect! Can’t wait to try it out this weekend 🙂
Kimberly @ Berly's Kitchen says
We don’t have an instant pot. Urg!! Wish we did because we would definitely make this. How can you not love macaroni and cheese with sausage?
Laura Dembowski says
I have heard so much about the instant pot craze and this mac and cheese alone makes me want to get one. Pure comfort!
Flavor Quotient says
Gorgeous! Love love love this smoked sausage idea in mac n cheese! Sharing!!
Karly says
It’s such a great addition!
Abeer Rizvi says
I have got to start using my instant pot more often! I can bet anything I would have no leftovers with this meal coz come on… look at all that cheesy goodness! 😉
Karly says
I think this is my favorite use for the IP!
Agness of Run Agness Run says
I love cheese and I think I could eat it every day, Karly! This is a mouth-watering recipe.
