This jambalaya is a one-pot dinner built on sliced andouille sausage, plump shrimp, and a big pile of green bell pepper, red bell pepper, onion, and celery, all simmered together with diced tomatoes and a smoky Cajun seasoning. The cauliflower rice goes into the pot with the tomatoes and broth and soaks up all of that spice while the shrimp turn pink, and the whole thing is done in about 30 minutes, start to finish. I make my own Cajun blend with spices like smoked paprika, garlic powder, oregano, thyme, and cayenne, but 2 tablespoons of storebought Cajun seasoning works just as well.

Frequently asked questions
Can I use storebought Cajun seasoning instead of making my own?
Yes. Use 2 tablespoons of storebought Cajun seasoning and skip the individual spices listed for the homemade version. If you are making your own, whisk those spices together in a small bowl first and set the blend aside until it goes into the pot.
Do I need to thaw the shrimp first?
Yes. The recipe calls for 1 pound of frozen shrimp, thawed. The shrimp goes in with the simmering mixture and cooks about 4 to 5 minutes, until it is pink and cooked throughout.
Do I have to cook the cauliflower rice before adding it?
No. The cauliflower rice goes into the pot frozen, along with the diced tomatoes, broth, and prepared Cajun seasoning, and finishes cooking as the mixture simmers.
How spicy is this jambalaya?
The heat comes from a quarter teaspoon of cayenne, three quarters of a teaspoon of chili powder, and the andouille sausage. The last step has you taste and add more salt, pepper, or cayenne, so you can raise the heat right at the end.
