What is in this Vegetarian Cajun Pasta Recipe?

So this dish came around when I was getting ready to re-make my beloved Instant Pot Butter Parmesan Spaghetti but, I turned out I was out of parmesan cheese. So that was not going to work. It was time for a new plan.

This Creamy Cajun Pasta began when I recently made Deviled Crab Cakes and decided it might be fun to see if I could make a combination twist of the two. And, thus began the Instant Pot Creamy Cajun Pasta.

What is Similar to Instant Pot Butter Parmesan Spaghetti?

Both use spaghetti as the form of pasta. Both come together in around 20 minutes with only about 5 minutes of hands-on time.

What is Different from the original?

This dish mixes up all the seasonings. Swaps the butter for mayo. Adds so Dijon and hot sauce and trades the parmesan for Monterrey jack cheese.

Can this Vegetarian Cajun Pasta Recipe be made Vegan?

Ideas to add to Vegetarian Cajun Pasta Recipe

As I said at the beginning of this post, I based this dish off the flavors of a crab cake dish, if I had had some fresh lump crab around I would have definitely attempted to mix that in to make sort of a crab cake pasta. And writing it, I’m still interested, that me be coming soon.

Otherwise some cooked andoiulle sausage or shrimp would pair amazingly well with this dish the only thing is is would increase the time.

For the sausage, I would add a bit of oil to the Instant Pot. Set to sauté and sear the sausage (sliced) until cooked. Set aside and stir through the final dish. Similarly, for the shrimp I would poach or grill it separately and then fold through the cooked pasta so it didn’t get over-cooked in the Instant Pot.
