Instant Pot Cajun Pasta

I get so excited every time I successfully create an instant pot recipe that’s a “dump it and forget it” type of dinner!  These type of meals are what I love to use my instant pot for the most, but I’m really picky that the end result has to taste just as good as if I took the time to make it in a skillet on the stove. Learn all of my instant pot tips and tricks!

For this easy instant pot pasta recipe you simple sauté the veggies and sausages in the bottom of the pot first, and then add the liquid and dry pasta. In one click of a button you have a delicious meal ready to go, and only one dish to wash!

How to make Instant Pot Cajun Pasta in 8 Steps:

  1. Prepare your ingredients.  Chop the vegetables and sausage into bite sized pieces.
  2. Turn your Instant Pot to sauté and cook the sausage, bell peppers, celery and onion in a little bit of oil, and then add cajun seasoning and garlic.
  3. Turn Instant Pot OFF.  
  4. Add chicken broth, milk, and dry pasta.  Make sure to press down the pasta to submerge it in the liquid.
  5. Cook on high pressure (manual)n for 4 minutes.
  6. Quick release.  Start slowly and then fully release the pressure.  Give the pasta a gentle stir.
  7. Turn the IP pot to Sauté. Stir in the parmesan cheese and parsley.
  8. Add cornstarch and milk that have been stirred together.  Stir it gently until the sauce starts to thicken.

Can I double this recipe?

  • Yes, you can double this instant pot pasta recipe by doubling ALL of the ingredients, including the pasta and liquid!  The cook time will STAY THE SAME.  You will notice your pot will take a little longer to come to pressure because of the higher volume of ingredients inside.

Ways to Adapt this Recipe:

  • Add or substitute different kinds of meat. Chicken would work if you cut it into bite-size pieces first (you can sauté it in the pot, just like the sausage, but don’t cook it all the way through.) Ground turkey, sautéed at the beginning, or different type of sausages would also work. Use what you have.
  • Add more vegetables. I like to add seasonal vegetables to this dish as well, like zucchini, summer squash, broccoli, and peas. I think it tastes best to sauté additional vegetables in the pot at the beginning, until tender, and then remove them to a plate and stir them at the very end, after the Instant Pot has finished cooking. That way you avoid them being overcooked and mushy.

You really don’t need a side dish with this instant pot pasta, but if you’d like to stretch it to feed more people you could serve it with a big green salad and crusty bread.

Don’t Have an Instant Pot? Make it on the stove!

Heat the oil in a large pan on the stove. Add the sausage and veggies and sauté. Add the seasonings. Add the dry pasta, chicken broth and milk but add an extra 1 cup of chicken broth, and an extra ½ cup of milk. Bring to a gentle boil, then cover and reduce heat to a simmer.

Simmer for 15-20 minutes or until pasta is tender, stirring once or twice during this time. Remove from heat and stir in parmesan cheese, parsley and cornstarch slurry. Cook just until sauce begins to thicken.

    Very tasty! This recipe is great to make ahead of time and then eat throughout the week. I added a can of Rotel to my mix, which was a great addition.

    I’m a 75 year old man enjoying life and learning to cook. I accidentally reviewed my internet recipes and found that I had 3 of yours. Now that I’ve printed a few more to try, this one is my latest in a long line of hits. Thanks for making my life more fun and delicious.

    The recipe was good but it is spicy. I used andouille sausage and half the amount of seasoning and it was very spicy for our family.

    So fast, so easy, SO delicious! This is a constant on my dinner rotation list. My kids gobble this up! Only modification I did was I used kielbasa sausage instead of Cajun to take away the heat for my littles but the flavor is still very much there!
