Oven roasting…duh.

There is a common complaint that cauliflower rice smells and tastes bad, kind of like rotten eggs. If you have tried making cauliflower in the past and were not pleased with the results then this is the method for you.  

The oven draws moisture out of the cauliflower which improves the texture and it creates this wonderful little crispy brown bits throughout the fluffy rice.

You can also make this in large batches while freeing up your hands and stove top so you can prepare the low carb curry, korma, or stir fry to enjoy with this crispy low carb rice.

3 Ways To Rice Cauliflower


Many food processors come with various grating discs which can be used to make perfect cauliflower rice very quickly. 

Install the larger disc in the food processor and break down the head of cauliflower into florets small enough to fit through the chute on the processor lid. 

Feed the chunks into the processor, and press down with the plunger. The spinning disc chops perfect rice every time. If you are making lots of cauliflower rice regularly like myself, a food processor with a grating disc is a worthwhile purchase.

The regular blade can be used to break down cauliflower as well, just don’t chop it too fine or it will become mush. Pulse it until the cauliflower has broken down into small couscous/rice sized pieces. 


Below are the key details you need to know to make your own cauliflower rice at home. 

Ricing Cauliflower:

The simplest way to get cauliflower rice is to buy it from the store pre-riced.

You can find this with the other frozen vegetables, or if you are lucky, your local grocer will have freshly prepared in house in the deli or salad bar area.

This can get expensive  so if you are eating a lot of cauliflower rice like we do, then its the most economical to make it yourself.

Cauliflower rice without a food processor


A simple cheese grater, sometimes called a box grater can make quick work of a full head of cauliflower. Break the head into manageable chunks and grate it using the larger holes on a grater.


If nothing else, you can use a regular knife. Simply dice the cauliflower into very small rice sized pieces with repeated passes of a large knife until the cauliflower is small enough.

It takes longer and gives you a more rustic rice, but before I had a food processor, this is how I made cauliflower rice all the time.

Hand Chopper

There are various styles of hand powered choppers out there that can make cauliflower rice very easily and are usually pretty affordable.

The downside is you will have to rice the cauliflower in smaller batches. 

Here are 2 great hand choppers for making cauliflower rice

If you need raw cauliflower rice as an ingredient in a recipe like jambalaya, then you are good to go from here!

Prepare For Roasting

To prepare the cauliflower for sheet pan roasting.

  1. Lay out riced cauliflower on a foil lined baking sheet. The foil will help prevent sticking. 
  2. Drizzle liberally with oil, salt, and pepper. Use your hands to toss everything really well to make sure that all the rice is well coated with the oil and seasonings.

Baking Times and Temperatures

What You Need: Foil lined baking sheet, olive oil, salt and pepper. 

Temperature: 400°F [205°C]

Cook Time: 35-45 minutes

You know its done when: The top layer has crispy brown bits and the rice below is tender and fluffy. 

Note: If your cauliflower rice is sharing the oven with the rest of your dinner, everything may take a bit more time. 

Cauliflower releases lots of moisture as steam in the cooking process which can raise the humidity of your oven. Not a big deal from some dishes, but if you are trying to crisp something up like the skin of chicken, it will take longer due to the extra moisture.

Your cooking time may vary depending on the amount of water in your cauliflower. Cook until the top layer is golden brown and starting to crisp. 
If the cauliflower is sharing the oven with other dishes be aware the humidity of the oven will be quite high from the cauliflower and you may need to adjust cooking times. 
Check the frozen vegetable section or the fresh produce deli area of your local grocer for pre-riced cauliflower and other vegetables. 
Store leftovers sealed in the fridge for use within a week.
Reheat in the microwave, or on a baking tray in the oven. 
Serving size will depend on the size of cauliflower you use. Always verify your own nutritional information based on the actual ingredients you are using with a recipe calculator like Cronometer
