Step by step directions
You can find the full list of ingredients and full printable recipe card at the bottom of this post, however I love to share tips along the way in case it’s helpful!
- Heat your butter and oil using the sauté function on your instant pot. After
your butter is melted, add sausage and celery and cook until your
sausage is beginning to brown and your celery is soft (Image 1).
- Add your minced onion, grated garlic, Cajun seasoning, and paprika to your
pot and mix using a wooden spoon until the sausage and celery are coated.
- Add your chicken broth and continue to cook while stirring occasionally until
your chicken broth has reached a slow simmer.
- Add pasta into your broth mixture, turn off the sauté function on
your Instant Pot, place your pressure cooker lid on your pot, set the valve
to the sealing position, and pressure cook on manual high pressure for 6 minutes (Image 2).
- Once your pasta is done cooking, initiate a quick release on your Instant
Pot. (“Quick release” or “manual release” means to turn the pressure valve to “vent” to release the steam and pressure. Natural release means to allow the Instant Pot to release the pressure on its own, which takes longer and typically makes the food cook longer inside, since it’s pressurizing for a longer time while naturally releasing.)
- Once all the pressure has been released, remove the lid and quickly stir in
your half and half and parmesan (Image 3).
- Add parsley to the top of the pasta and serve (Image 4).
How to make this recipe healthier
There are a few easy things you can do to make this recipe slightly healthier. You can easily throw in veggies like bell peppers, mushrooms, and/or broccoli when you add in your pasta.
In addition to including more vegetables, you can also use chickpea pasta or another lentil pasta. These types of pasta are more nutrient-dense and have more protein than typical pasta. Those types of pasta cook the same as regular noodles and you can find them at most grocery stores. Or, feel free to use gluten-free pasta as well!
Yes, you can use a different style of noodles. I’ve found that penne gives this instant pot pasta recipe a nice texture and flavor but spaghetti noodles, bowtie, or rigatoni would also work. Each pasta may have different cook times so adjust if needed.
Yes! You put uncooked pasta in the instant pot. For best results and to achieve al dente tender pasta, make sure you follow the directions because it can be tricky to get the perfect pasta texture.
Creole seasoning is a great substitute for Cajun seasoning. If you do not have Cajun or creole seasoning, you can make your own by combining paprika, salt, garlic powder, black pepper, white pepper, onion powder,
oregano, and cayenne.
How do I store leftover instant pot pasta?
This instant pot spaghetti recipe reheats so well and is great for leftovers the next day! To store this dish, simply put your leftovers in an airtight container and place them in the refrigerator for up to 5 days. To reheat, you can add a splash of milk and parmesan cheese to the pasta and cook on the stove or reheat in the microwave. You could also add more pasta sauce if desired!
Substitutions and Add-ins
- Andouille sausage is a slightly spicy sausage that can be hard to find at the grocery store but you can easily swap that out with Polska Kielbasa sausage. For a healthier alternative, you can buy a turkey Polska Kielbasa-style sausage. Or, feel free to change up the meat totally and use ground beef, chicken, ground turkey or leftover meats from the night before!
- If you like your pasta thick, you can use cream instead of half and half. If you’d prefer to stay away from cream altogether, you can use any type of milk and a thickening agent like corn starch.
- I don’t know about you, but I ALWAYS top my pasta with shredded parmesan cheese and fresh basil. I think it gives this instant pot pasta extra flavor and texture which is always welcomed in my recipes!
- If you find that spicy pasta isn’t your favorite, you leave out the cajun seasoning and use seasonings such as garlic powder, paprika, parsley, Italian seasoning, red pepper flakes, and/or onion powder. Simply add these spices along with the rest of the spices in this instant pot recipe.
