Cajun Cauliflower Dirty Rice

With a handful of common ingredients, you can recreate the classic New Orleans style flavors of your favorite dirty rice with cauliflower! This lower carb take on a Cajun classic is a dinner staple in our house!

It’s no secret that I’m not the biggest fan of cauliflower, but eating a low carb diet has helped me master the in’s and outs of making the best cauliflower rice (and cauliflower mash). I especially love this Cajun inspired version of a classic dirty rice that brings me back to the carb food filled days of NOLA. 

This recipe is a handful of staple ingredients from the fridge (sausage, onion, celery and peppers) and I love how easy it comes together. With a few helpful cooking tips and techniques and 30 minutes, you are on your way to making a killer dinner.

“School” Supplies:

  • Cutting Board & Knife
  • Large Frying Pan
  • Spatula
  • Baking Sheet

“Class” Notes:

This recipe is a great meal for a busy night or if you’re looking for a solid meal prep option. The base of this recipe comes from the classic flavors of Cajun dirty rice and is made up of what many call the “Cajun mirepoix”.

A standard mirepoix is carrots, onion, and celery. The Cajun version is green peppers, onion, and celery (and unofficially garlic). Slice and dice your veggies and then set them aside.

If you are using already riced and frozen cauliflower (the easiest choice), try baking it. I have found baking the frozen rice in a 350 F oven for about 10 minutes gives you a chance to season it, avoid having a rather funky smelling kitchen, and allows the rice to defrost and not become a soggy mess.

To make your rice, cook the pork or sausage until no longer raw and nicely browned. Add in the veggies and some garlic and saute until tender. Then mix in the cauliflower rice right before serving.

I prefer to add shrimp to the top of my rice, but it tastes great as is! You could also add chicken or get real Cajun and some crayfish. I even enjoy the leftovers for breakfast the next day by adding a fried egg on top!
