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.

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.
