“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 mirepoix is green peppers, onion, and celery (and unofficially garlic). Slice and dice your veggies and then set them aside so you’re ready to cook when needed.

How To Prepare Your Cauliflower For Dirty Rice:

If you are using already riced and frozen cauliflower (the easiest choice), try baking it. I have found baking the frozen cauliflower 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.

Mix in some olive, the frozen cauliflower rice (or fresh riced cauliflower works here too) and a few teaspoons of the Cajun Dry Rub recipe. Place it on a baking sheet and spread it out thinly to bake. Cook it until roasted, heated through, and any moisture has absorbed.

How To Make Your Dirty Rice Mixture:

While your cauliflower rice starts cooking in the oven, grab a pan and on the stove top cook the ground pork or sausage until no longer raw and nicely browned.

Add in the veggies and some garlic and sauté until tender. Season the whole thing with a little more Cajun dry rub to tie it all together.

Your cauliflower rice should be cooked by the time your sausage and mirepoix mixture is ready. Fold everything together and cook a few minutes to get it fully combined.

Adding Garlic Cajun Buttered Shrimp:

I prefer to add shrimp to the top of my rice for some extra protein, but it tastes great as is! I choose to cook my shrimp in some garlic, melted butter and the Cajun rub. You could also make my keto friend Po’ Boy style shrimp I use in this salad recipe too.

You could also add chicken or get real Cajun and some fried crayfish. I even enjoy the leftovers for breakfast the next day by adding a fried egg on top!
