What is Jambalaya?
Jambalaya is an American, Louisiana-born, Creole and Cajun white rice dish that draws influence from Spain, West Africa, and France. It consists of mainly pork and seafood like andouille sausage, crawfish and shrimp, but also loads up on vegetables like bell pepper, onion, and celery.
In this version, we replace white rice with cauliflower rice! You can also replace the cauliflower rice with your own preference of rice.
How to make Keto Sheet Pan Jambalaya
Let’s gather up these easy ingredients:
- Red bell pepper and green bell pepper
- White onion
- Olive oil or avocado oil
- Kielbasa sausage
- Cajun seasoning
- Cauliflower rice (you can prepare this by pulsing cauliflower florets in a food processor, or use store bought)
- Cherry tomatoes
- Garlic powder
- Raw shrimp
- Lemon juice
- Green onion and parsley for garnish
We start by preheating the oven to 425. We’ll combine sliced bell pepper, onion, and the sliced sausage in a large bowl. Drizzle this with oil, and sprinkle with salt and cajun seasoning.



Place on a sheet pan and roast for about 8 minutes. While the veggies and sausage are roasting, prepare the shrimp by seasoning with remaining seasoning. Remove the sheet pan after 8 minutes, and add cauliflower rice and cherry tomatoes. Place the shrimp on top.
Roast another 6 – 8 minutes or until shrimp is done. Remove from oven and serve with a squeeze, of lemon, fresh parsley or green onion.
A Few Questions Answered
- Can you omit the shrimp in Jambalaya? Yes! Absolutely. You can do all sausage, and add another pound. Another option is to use chicken breast cut into pieces.
- Can you use regular rice in place of cauliflower rice? Of course! You can even swap out with brown rice, or another grain of choice.

Storing leftovers
This dinner is one you can meal prep or enjoy as leftovers the next day. In fact, the flavor may even be better!
- To store: store the leftovers in the fridge for up to 3-4 days.
- To freeze: freeze in an air tight container for up to 3 months.
- Reheat: gently heat a large portion in the oven at 325 for 15 minutes, or place a portion of the meal in the microwave for 2-3 minutes.

Garlic powder for?
I have taken that out. It was intended for the cauliflower rice, but is not necessary.
Really good and easy. My store no longer carries cajun spice so I made my own. I needed to cook the first half of the recipe longer than stated but the time for the shrimp was perfect. Have made this twice and will again.
Really good flavors but needed to cook longer. I used andouille instead of kielbasa. The lemon at the end is a must
When is the garlic powder added?
I have taken that out. It was intended for the cauliflower rice, but is not necessary.
Can i double the recipe on one baking sheet? Will it fit
Made this tonight. It was amazing. I’m really loving the keto lifestyle and it’s mainly because the good recipes like this one that make it easy. Will definitely remake.
Can this be frozen? I want to make ahead of time for family gathering
This would be difficult to freeze, mainly because of the cauliflower rice. Unfortunately, it would turn a little mushy when re-heated!
So delicious! Added a bit more cook time and made my own cajun seasoning. All elements were great together & super easy to prepare. We will make again!
Love this feedback, thank you Amy!
Hi, what are the carb, fat and protein values please?
It’s under the recipe card in the notes section
If you use frozen cauliflower rice for this recipe, do you have to thaw or otherwise prepare it, or simply add the (frozen) cauliflower rice as you would fresh cauliflower rice? Thanks!
Hi Michelle, thaw out the frozen cauliflower rice before adding it to the sheet pan.
