Ingredients

  • Red onion – I love using red onion anytime I use smoky flavors, but you could also use a white or yellow onion or even green onions.
  • Celery – traditional in Cajun and Creole cooking, celery adds a crunch and ton of flavor to the dish.
  • Roasted red peppers – using roasted red peppers helps to add that smoky flavor, elevating this dish quickly since it doesn’t spend much time cooking.
  • Spices and salt – Dried thyme, smoked paprika, garlic powder, ground cumin. cayenne pepper
  • Cauliflower rice – I prefer frozen cauliflower rice over fresh, but use whatever you have on hand.
  • Coconut aminos – this helps to add a depth of flavor to the dish without having to cook it all day. You could also use soy sauce or gluten free tamari.

How to make cauliflower dirty rice

Start by finely chopping the red onion and celery. Take the bags of cauliflower rice out of the freezer to start to defrost a bit while the veggies cook.

Preheat a large skillet (cast iron or stainless steel) over medium heat. Once the skillet is hot, add avocado oil spray or olive oil spray (or about 1 tbsp. avocado oil or olive oil) to the pan. Add the onions and celery and cook over medium heat 4-5 minutes, allowing the onions to turn translucent and the celery to start to break down.

While the onions and celery are cooking, chop up the roasted red peppers. Take them out of the jar (discard the liquid they are soaking in) and finely chop them. Add the chopped red bell pepper along with the salt and spices to the veggies. Stir well.

Break apart any large chunks of the cauliflower rice in the bag before opening the bags and pouring them over the hot veggies. Add the coconut aminos on top of the cauliflower rice. Cook 4-5 minutes, stirring occasionally.

Using a spoon or spatula, move all the ingredients to the outside rim of the pan, letting all the excess liquid to pool up in the center. Turn the heat to medium high and allow this excess water to boil off 3-4 minutes.

Top tips

  • Take the time to break up any large clumps of frozen cauliflower rice in the bag before adding it to the pan to help cut down on cooking time.
  • When working with frozen cauliflower rice, you will notice that it often sweats off excess liquid, making the cauliflower rice mushy. This is why I advise moving all the veggies to the outside rim of the large skillet and cooking off the excess liquid to help ensure the cauliflower rice doesn’t get soggy.
  • I like to use frozen cauliflower because I find it has a milder flavor vs. fresh cauliflower rice (especially store bought). If you do use fresh cauliflower rice, you may need to cover the pan and allow it to steam for 3-4 minutes ensuring it gets cooked through before serving.
  • Traditional Creole dishes use the holy trinity – a combination of onion, celery and green pepper. I prefer the flavor from red bell pepper instead, as it’s sweeter and when it’s roasted it adds a smoky flavor to the dish. If you want this to be more traditional, use green pepper and white onion in place the roasted red pepper and red onion.

What is dirty rice

Traditional dirty rice is a dish famous in Cajun or Creole cooking. Typically the rice is “made dirty” by cooking it with ground sausage, meat or chicken livers. The rice is cooked with the holy trinity of veggies – onions, celery and green peppers along with traditional cajun spices.

To allow this to be more of a side dish and to be vegan friendly, I decided to not add any sausage, ground meat or chicken livers. To make it more of a meal, add your favorite protein (ground sausage, turkey, beef, red kidney beans) for a more filling dish.

What to add to creole spiced cauliflower rice

  • Protein: Ground sausage, ground turkey, ground beef, shrimp, tofu, smoked oysters, smoked sardines, red kidney beans, black beans, lentils.
  • Spice: Red pepper flakes, cayenne pepper, jalapeno peppers (fresh or pickled)
  • Veggies: Zucchini, summer squash, cilantro, green onions

How to make cauliflower rice

Use the food processor

  • Cut the green leaves and thick bottom stalk away from the cauliflower. Chop the cauliflower into small enough pieces that they will easily fit into your food processor (you don’t need to worry about the shape of these pieces).
  • Add about ½ of the cauliflower to the food processor and process on high for about 20 seconds, until the cauliflower resembles rice. Note: Some people like to use the larger grater attachment of their food processor for this since it creates a more uniform consistency.
  • Process all the cauliflower and you can use it immediately, store it in the fridge for 3-4 days or freeze it for up to 2 months in a well-sealed freezer safe bag or container.

Use box grater

  • Cut the green leaves and thick bottom stalk away from the cauliflower.
  • Grate the cauliflower using the large holes on the box grater. Grate around the stem of the cauliflower.
  • Store in the fridge for 3-4 days or freeze it for up to 2 months in a well-sealed freezer safe bag or container.

How to store leftovers

  • Fridge: Store leftovers in the fridge for up to 5 days in an airtight container.
  • Freezer: Stove leftover cauliflower dirty rice in the freezer for up to 2 months in a freezer safe bag or container.
  • To reheat after defrosting, it’s best to use a skillet to reheat the dirty cauliflower rice as the cauliflower rice, celery and peppers can get watery when defrosting.

  • After cooking for 3-4 minutes, move the cauliflower rice mixture to the sides of the large pan, allowing the excess liquid to pool up in the center. Turn the heat to medium high and allow this to boil/cook off. After 3-4 minutes most of the liquid should be gone. Stir well and cook 1 more minute over medium high heat to ensure as much excess liquid has cooked off before serving.

    This is a really delicious vegetarian version of ‘dirty rice’. I added a bit of the roasted red pepper liquid at the end and let it evaporate as I allowed the cauliflower to become really tender. Thanks!

  2. I was recently diagnosed with celiac disease. Iโ€™m 26, so having to do an entire lifestyle change has been a bit overwhelming since all the food I had in my daily routine was basically no longer allowed to be a part of daily routine! Who would have thought that some of my โ€œhealthyโ€ items werenโ€™t actually good for me! Stumbling across your site and recipes has been amazing! Itโ€™s given me so many ideas and Iโ€™m so excited to actually cook & bake again. Thank you!
