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 of 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 the pressure. 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.

  1. Can I sub heavy whipping cream for the evaporated milk? Also, can I use chicken broth instead of water for deeper flavor?

    1. I would like to cook this in crock pot. Do you have instructions for a crock pot way of cooking this tadty recipe

      1. Hi Karen! I would just cook the pasta on the stove and drain it. Then just add the rest of the ingredients and mix. You can brown the sausage on the stove if you want, but it’s not necessary, since the recipe calls for fully cooked sausage. Hope this helps!

    1. 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!

  2. 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!

  3. 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!

    1. 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!

  4. 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.

    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

    1. 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!
