Roasted Cauliflower Rice
Soggy cauliflower rice is the worst and if you think you don’t like cauliflower rice, that’s probably how you’ve been eating it. Roasting cauliflower rice gives is much more flavor and the texture is firmer.
Roasted cauliflower rice tastes delicious, it has an almost nutty flavor or toasty flavor. I think it tastes similar to brown rice, but better. It’s my favorite way to make it!
Serve it with dishes that you traditionally serve rice with, and you’ll find you don’t even miss real rice!
I really love cauliflower rice with dishes like meal prepped meatballs, air fryer chicken tenders, BBQ pork chops, and healthy Beef and Broccoli Stir Fry.
I almost always use frozen cauliflower rice, found with the vegetables in the freezer section. It keeps a long time in the freezer and all the work is already done for me.
It’s the perfect healthy side dish and great for meal prep! Use this roasted cauliflower rice recipe in place of white rice or brown rice for a rice substitute.

To make cauliflower rice for meal prep, follow the directions to prepare the cauliflower rice in the recipe below. Once cooked, portion the cauliflower into 4 meal prep containers.
Add additional protein and veggies (like blanched green beans!) to your meal prep containers to make a complete meal. Then just heat and eat!
I often add roasted cauliflower rice to my weekly meal plans in place of regular rice. It goes great with so many different types of meals, cuisines, and proteins.

Ingredients for Roasted Cauliflower Rice
I prefer McCormick Garlic Salt. If you don’t have garlic salt, you can use a combination of fine sea salt and garlic powder.
Feel free to change up the flavors and add your favorite spices. I like to keep my cauliflower rice on the basic side so that I can easily pair it with different types of meals.
Onion powder, fresh herbs, or parmesan cheese would also be great additions. Just be sure to count the extra calories from the cheese or other mix-ins you add.

How to Make Roasted Cauliflower Rice
Step 1. Preheat oven to 425 degrees Fahrenheit and spray a rimmed baking sheet pan with non-stick spray (I use Chosen Foods Avocado Oil Spray).
Step 2. Add the cauliflower rice to the sheet pan with olive oil, garlic salt, and pepper. Mix thoroughly to coat the cauliflower completely.
Step 3. Spread the cauliflower out in an even layer. Roast for 20-25 minutes, stirring halfway through, until it starts to become golden brown.

How to Make Cauliflower Rice with a Whole Head of Cauliflower
If you can’t find pre-riced cauliflower, you can make your own with a head of cauliflower by following these easy steps.
Step 1. Trim the end off the raw cauliflower and break it into florets.
Step 2. Add the cauliflower florets to the bowl of a food processor and pulse until the cauliflower is broken down into small pieces about the size of rice or slightly larger.
If you have a grating disc, feel free to cut the cauliflower into large chunks and let the grating disc do all the work!
You could do this with a box grater if you don’t have a food processor. I just don’t recommend it because it’s a lot more work and makes a big mess.

Equipment Needed to Make Cauliflower Rice in the Oven
- Rimmed Baking Sheet
- Parchment Paper or Aluminum Foil
- Food Processor – only if you’re making your own cauliflower rice
Tips for Making Cauliflower Rice
- You can double this recipe. Just be sure to use 2 sheet pans and rotate them during baking so that the cauliflower cooks evenly.
- Making cauliflower rice with frozen riced cauliflower will take a few minutes longer to bake than fresh cauliflower.
- Roasted cauliflower rice will last up to 5 days in the refrigerator in an airtight container.

This is a simple and different side dish, no more heavy rice, potato or else! Cauliflower is the new star! Perfect to get in our bikinis for the summer!
Cauliflower is so versatile and goes great with so many dishes!
Cauliflower rice is such a nice change from regular rice. The perfect side dish for any dinner meal. A great way to enjoy this tasty veg.
Thanks Gloria, I agree!
I simply love your tips for the cauliflower rice. I haven’t made the veggie into rice or used it as rice. Call it laziness or not wanting to make a mess in the kitchen but I’ve only been using big florets. I made your recipe and I’m thrilled with how it turned out. Delicious! I’ll be making it again– often.
Thank you Marisa, so glad you enjoyed it!
Love that roasted flavor so much! Especially for an ingredient like cauliflower that can be a little bland on its own
Yes, roasting cauliflower really brings out the flavor!
Such a simple idea of roasting cauliflower rice takes it to the next level! I am in love with the nutty flavor and simple spices.
The nutty flavor is unexpected but so delicious!
I needed a slightly lighter side dish and I love how this one came together. The cauliflower rice was incredible and so simple to make for dinner.
Thanks Julie!
