This smoked sausage mac and cheese is a pressure cooked, one pot dinner made with Kielbasa or any smoked sausage. Family loved!

Who can argue the convenience and deliciousness of mac and cheese with sausage made right in your pressure cooker? It's just like Instant Pot Macaroni and Cheese with smoked sausage added to it. It makes weeknight cooking not like cooking at all! If you like one-pot Instant Pot entrees, you'll love my pressure cooker chicken alfredo and Instant Pot tuna casserole as much as kielbasa mac and cheese.

What is Kielbasa?
It’s a pre-cooked Polish sausage that's sold in retail packs at most grocery stores. In this recipe, we simply pressure cook it with the pasta, slice it, and add it back to the mac and cheese. You can use any smoked sausage for this recipe for a different flavor or texture, or due to limited availability.

Chantal says
This is definitely a kids favorite and my go-to when I am short on time! It's super easy and delicious. I often double the amount because we love having it for leftovers. I actually discovered an even shorter shortcut, if you could imagine, for the sauce. Instead of adding flour and milk, put in a can of condensed cream of mushroom soup. It pairs really well with the shredded cheese and comes out very creamy. Thank you Traci for the awesome recipe. This definitely makes the family weeknight list!
The Kitchen Girl says
Awesome Chantal! So glad you're enjoying the recipe 🙂 There's no flour added to this one, but the mushroom soup is def an option. Thanks for taking the time to leave feedback. Cheers!
Anna says
This would not be nearly enough for our 5 adult family . Can I double everything and use the same cooking time?
The Kitchen Girl says
Hi Anna, sure can! As long as you have a 6 quart cooker or larger. Thanks for asking! Let me know if you have other questions...enjoy! 🙂
Heather says
Hi! I measured out 2 cups of dried macaroni- should I have used a whole 16oz box instead? It turned out too wet. Thank you!
The Kitchen Girl says
Hi Heather, I wouldn't double because 1:1 macaroni and water is pretty standard for IP mac n cheese. Once cooked, there should be some liquid bc that (along with added milk and cheese) makes the cheese sauce creamy. Not sure what happened for you there but things to rule out would be A) shortened natural pressure release time B) different model cooker used C) different ingredients/measurements used.
Suzie says
This sounds wonderfully easy and delicious! Ca I add a vegetable? Maybe peas. How would this change the directions? Thanks!
The Kitchen Girl says
Hi Suzie! Yep, you can add peas either before or after the pressure cook cycle. If you like your peas barely cooked, add them after. It's a quick pressure cook cycle so if you cook them with the pasta, they'll still be in tact, just not as bright green. Hope that helps...enjoy!
