Why This Recipe is a Keeper!

My clients don't want bits and pieces of vegetables left in their refrigerator because they typically don't cook. If I don't have a specific use for it, there's no guarantee I'll use it either. If you're a regular reader, you know I'm averse to food waste.

I was making Cauliflower Rice for a client one day and had some leftover carrots, red bell pepper, zucchini and yellow squash from some other recipes I made. I decided to roast them and stirred them into the cauliflower rice I had already made. Voila! Roasted Vegetable Rice with Garlic and Parmesan was born!

That night I got a text message from my client raving about it! They said it was a welcome change from just cauliflower rice.

This recipe takes cauliflower rice to a colorful, festive level with additional vegetables, garlic and nutty Parmesan cheese!

How to Make Roasted Vegetable Rice with Garlic and Parmesan:

Recipe Ingredients:

Here's everything you'll need to make this recipe along with how to prep. See the riced vegetable recipe card below for the exact quantities.

Ingredient Notes:

Cauliflower: Here's where purchased "riced" cauliflower (also called cauliflower "pearls") will save you some time. If you prefer to make it yourself, I recommend grating it rather than making it in a food processor. You’ll have “grains” that are more similarly sized than if you make it in a food processor. However, If you want/need to make them in a food processor, here's a great tutorial on making riced vegetables from Cotter Crunch.
Carrots: Save time by using purchased julienned carrots then chopping them.
Red Bell Pepper: You can also use yellow or orange bell pepper; as long as it's a sweet pepper. I'm not a fan of green bell pepper with cauliflower as the flavors "fight" (in my not-so-humble opinion).

Step-By-Step Instructions:

Preheat your oven to 425 degrees.
Gather and prep all the ingredients.
Line two baking sheets with nonstick aluminum foil.
Spread the cauliflower pearls (riced cauliflower) onto the prepared baking sheet. Add the carrots, drizzle with olive oil, stir and season to taste with salt and black pepper.

Place both baking sheets in the oven and roast for 12 minutes.
After 12 minutes, take both baking sheets out of the oven.
Tent the sheet pan with the cauliflower and carrots with aluminum foil or another identically-sized sheet pan to keep it warm.
Add the garlic to the pan with the zucchini, yellow squash and red bell pepper, stir it in and place it back in the oven for another 4-5 minutes.

Chef Tips and Tricks:

Zucchini and yellow squash are super easy to dice:
- Remove the stem and flower end.
- Cut into planks.
- Stack half the planks and cut into strips.
- Dice.
If you don't have nonstick aluminum foil, use regular aluminum and spray it with cooking spray.

Frequently Asked Questions:

Are riced vegetables good for you?

Yes! Just like vegetables, in general, are good for you, riced vegetables are very good for you. The benefit to mixing them up is you get the various benefits of other vegetables. Meaning, that cauliflower provides a set of nutrients, broccoli has a set of nutrients and so on.

What's the best kitchen appliance to make vegetable rice?

A food processor is the easiest way to make vegetable rice. However, it doesn't create even "grains" and it's possible to overprocess the vegetable. It's also possible to create vegetable rice with a grater using the side or section with the largest holes. If you don't mind some chopping, a good sharp chef's knife also works.

What other vegetables can I use in roasted riced vegetables?

Try: Diced sweet potatoes, broccoli (great way to use up broccoli stems), other sweet bell peppers such as yellow or orange, cabbage, Brussels sprouts, green beans, turnips, rutabaga and kohlrabi. Simply adjust roasting time as needed.
