Whole30 cajun shrimp skillet with cauliflower rice and sweet potato chunks. This 20-minute meal is perfect for the weekdays!

Last week while cleaning my fridge I found an old head of cauliflower that my mother-in-law insisted in buying, affirming that I would surely make something good with it. Only thing is, she went back to her home in Florida and I completely ignored her wishes and that (now) buried head of cauliflower.

To my surprise the cauliflower remained beautifully white and looking as fresh as ever. I felt a knot tight in my gut as I picture myself tossing that entire vegetable in the trash, but then I felt slightly better as I realized I could feed it to my mother’s chickens instead. Good solution!

Funny how our brain works! Mine seemed to be working well that day as the third and last line of thought came as a reminder that I AM doing the whole30 diet and so… hello cauliflower!!

This long and hopefully not so boring story is to say that I do not like cauliflower or anything that is made with cauliflower, including ‘rice’. It’s blend and boring!

However, I took advantage of the fact that my brain seemed to be working well that day (I believe that having a clear(er) head is one of the benefits of the whole30 diet!), and made sure to transform my head of cauliflower into this AMAZING Whole30 CAJUN SHRIMP CAULIFLOWER RICE recipe!

what is cajun seasoning

Cajun seasoning has a smoky peppery tasty and is bright red colored. Cajun seasoning is used often in barbecue or grilled recipes, however you can still use the cajun flavors to season any recipe.

There are a lot of cajun seasoning blends on the market, some can be spicer than other but they all have a bite. I’d say that most cajun blends have a mild-medium level of spiciness, so if you have low(er) tolerance for spiciness or (like me) you love spicy foods, then a good idea is to make you own so that you can control the level of spiciness.

how to make cajun seasoning

Most cajun seasoning will include flavorful components such as garlic and onion powder, oregano and thyme, and a mix of chili flakes, cayenne pepper and smoky paprika. However, if you don’t have all the ingredients you can still accomplish the desired flavor.

Here is what I used to make my cajun seasoning:

  • Onion Powder
  • Oregano
  • Chili pepper flakes
  • Spoked paprika
  • Tomato paste!

Yes, I added tomato paste for coloring. Stir everything into a paste and make sure the shrimp is completely coated in this cajun paste before cooking.

how to make cauliflower rice

If your heart’s desire has brought you to this recipe because I claimed to offer you a very flavorful cauliflower rice, yes you are at the right place!

I will be totally honest with you, cauliflower rice does NOT have a place in my heart. Don’t rush to blame me, I come from the land of color and flavor (Brazil) and cannot help myself in that department. My job here was to change my own mind about cauliflower rice’ blend status, and perhaps yours too!

And I did it! 🙂

First step is to make cauliflower rice. And by that I mean turn a head of cauliflower into ‘rice’ like crumbles. I love this guide from Love and Lemons and the fact that she added scallions for a pop or color and inch of flavor.

But I took one step further, but adding lots of color and flavor! As for the pop of greens I used kale but you can use anything from parsley, cilantro, tiny broccoli crumbles, scallions…

So here is how it goes. Crop, shred, blend or process your head of cauliflower into crumbles. Then add in your choice of greens. Set aside until it’s time to add on to the shrimp skillet.

how to make this whole30 cajun shrimp skillet with cauliflower rice

Now that you have your cajun ‘paste’ and cauliflower rice ready, the next steps are as following:

  1. Heat oil in a medium non-stick skillet. I don’t recommend using a cast iron because the cauliflower rice can stick to the bottom. Cook the shrimp to desired doneness, about 3-4 minutes on one side.
  2. Flip the shrimp to cook on the other side.
  3. Immediately add in the cauliflower rice, top with sweet potato chunks (I used frozen roasted sweet potatoes), and sprinkle with remaining olive oil.
  4. Cover the skillet, lower the heat and cook for 5 minutes.
  5. Stir shrimp and cauliflower rice together. Garnish with fresh cilantro and serve!

  1. I should have used common sense when you said cubed sweet potatoes. Maybe you meant minced. Sweet potatoes dont cut in five minutes. I ended up takinog the potatoes out and microwaving them and then mixing them back in. Also the cajun seasoning was dry with no liquid other than tomato pastys which is not very liquidy. Probably won’t tryi this one again.

    1. Thanks for taking the time to write your experience Peggy, sorry to hear it wasn’t a good one. I made this recipe twice before posting with good results (as pictured) but I will re-do making a few alterations to make sure that others don’t have a negative experience as well.

      1. I realized my mistake. In the recipe it says just to use cubed sweet potatoes but in the writing above you suggest using roasted sweet potatoes. I had used raw. Also in the recipe it says to use frozen cauliflower rice but in the writing you talk about using fresh cauliflower, so the cold probably didn’t help either. I will have to read the whole article when I follow your recipes in the future. Normally I love everything I have cooked from your site.

  2. This was a hit with my husband and myself! I am going to figure out how to make the shrimp a bit more saucy of a dish, maybe add some white wine, so that it can be poured over the cauliflower rice. I didn’t have green onions so I sautéed some red onion and added it to the rice with some butter and garlic, black pepper salt combo. Next time I will add more Cajun seasoning on the shrimp. I sauted a lot of fresh, minced garlic cloves that I added to the shrimp. I used frozen shrimp that I thawed a couple of hours earlier. Super quick and easy meal. Had sour dough bread and garlicy green beans as our sides, along with a couple of glasses of red wine. Thank you!
