This Instant Pot Cajun Pasta was born on one of those nights where we needed dinner fast, and I had to use what we had on hand. A quick Instant Pot pasta dish always comes to the rescue, and this one turned out so delicious I just had to share!

What Ingredients Will I Need for Spicy Cajun Pasta?

The first time I made Instant Pot Cajun Pasta I used venison sausage because it’s what I had on hand. It was delicious, but I really wanted to make it strictly Cajun for the recipe I’d share on the blog. So, in order to perfect it, I now make it with Andouille Sausage. It’s not necessary to use Andouille, but it gives it the perfect touch.

Of course, you’ll need some Cajun seasoning. I love Tony Chachere’s, it’s perfect in this dish. Other than that, some cheddar cheese, a couple cans of Ro-tel, pasta and you’re set!

Avoiding a Mess When Cooking Pasta in the Instant Pot

You may have heard, or it may have even happened to you, that when you cook pasta in the Instant Pot, sometimes the release can be messy! I have a solution for this, and you can read all about it here.

The trick really works, and I always use it when making plain pasta. The first time I made this pasta dish though, I didn’t do it, and I had a bit of a mess when releasing. Rigatoni seems to be especially messy when doing a pressure release. So I decided to use the trick the next time I made this recipe, and it made a huge difference.

An Instant Pot Pasta Dinner Perfect for Busy Nights

This Instant Pot Cajun Pasta is the perfect recipe for those nights when you’re running kids around, and you need dinner on the table fast. On nights like those, which often happen around here, pasta is my go to. The kids love it and making it in the Instant Pot is so easy and fast. If your kids love pasta, then you’ll also want to try my Instant Pot Cheeseburger Mac and my Instant Pot Taco Pasta.

This Cajun Pasta does have some spice to it, so make sure to take that into consideration. My family is a fan of spicy food, so it’s perfect for us. My Instant Pot Cajun Pasta is not killer spicy, but it definitely has a nice kick.

Kitchen Prep Tools, Utensils & Appliances

Here is a list of the kitchen prep tools, utensils, and appliances I used to make this recipe.

Prep Tools & Utensils

This recipe uses only a few simple ingredients that are just dumped into the pot. You’ll need very few utensils and cleanup will be a breeze.

  • You will need a large measuring cup for measuring the water and a set of measuring spoons for the Cajun seasoning.
  • I make sure to purchase two 2-cup bags of shredded cheese to make things easy for this recipe. But, if you are buying a large bag or shredding your own cheese, then you’ll need a measuring cup. I love saving space where I can, and a good set of stackable measuring cups really does help save valuable space in a crowded kitchen drawer.
  • When mixing the evaporated milk and cheese into the pasta, you’ll want to use a wooden or silicone spoon. I love my silicone spoon because it’s just so pretty. 
Appliances & Cookware

This recipe is perfect for both the 8-quart and 6-quart Instant Pot.

    I’m thinking of making this one night but can you use a different pasta?

  • Lori says:

    I don’t have an Instant pot! Could I make this in a crock pot?

    • Hi Lori! I would say make it on the stove if you don’t have an Instant Pot. It’ll be quick and easy, just a little more clean up than the IP since you’ll make the pasta and then drain it, and then add the rest of the ingredients. Thanks for stopping by!

  • Ellie says:

    Can I make this work the delay setting (2hr delay), or will the pasta get too mushy?

  • Ellie Mae says:

    Both times I’ve made this, the family gobbled it right up! I decreased the cheese a bit and it still tasted FANTASTIC! Thanks for the great recipe and tips!

  • Danielle says:

    Hi there! I am planning to make this for dinner tonight but I’m confused about the pressure release. I see you say Natural release for 2 minutes but then state to use the trivet trick—wouldn’t you only do that for the rapid release? My pin never drops from natural release after only 2 minutes and I don’t want my noodles to overcook. I typically always see rapid release for pasta dishes in the IP so they don’t overcook. Can you clarify for me?! Thanks so much!

    • Hi Danielle! When a recipe asks for 2 minutes natural release that means you let the two minutes go by after cooking and then you do a quick pressure release. So if a recipe calls for 10 minutes NPR, you let it naturally release for 10 minutes and then release the rest of the pressure manually (quick pressure release) until the pin drops. So for this recipe, when your counter reads L0:02, then you release the rest of the pressure manually u til pin drops. I hope this make sense, let me know if you still have any doubts. And yes, you can also do the trivet trick on this one. It will still help when you release the pressure after the 2 minute NPR. Let me know if you have any other questions!

  • Gina says:

    Loved this recipe! Used three cans of Ro-tel: two of the mild, and one hot with the habaneros, gave it a little extra spice but it still turned out wonderful.

  • Laura Strobel says:

    Hi Valerie, would there be any difference in the amount of water/cooking time if you were using a gluten free, rice based pasta? Thanks, Laura

    • Hi Laura! I have never cooked gluten-free pasta (it’s on my to-do list!), but from what I understand you do need to cook it longer than regular pasta. I couldn’t give you an exact time though as I’ve never tried it. Thank you for stopping by the blog!
