Why I Created This Recipe
Like many people, I was curious about cauliflower rice when it first became popular. The idea sounded great, but plain cauliflower rice tasted exactly like what it was... cauliflower.
That sent me into the kitchen looking for ways to make it something I'd actually crave.
Inspired by the flavors of Mexican and Spanish-style rice dishes, such as my Spanish Chicken and Rice (Arroz con Pollo), I combined tomatoes, peppers, garlic, and warm spices with cauliflower rice. The result was a flavorful, vegetable-forward side dish that delivered all the bold flavors I love without relying on traditional rice.
This Mexican-Style Cauliflower Rice was one of the first versions I developed, and it's still one of my favorites. It's quick, versatile, and pairs beautifully with everything from tacos and enchiladas to grilled chicken, pork, and seafood.

- 1 tablespoon chili powder Gebhardts preferred
- 1 teaspoon cumin powder or to taste

Ingredients and Substitutions
Riced Cauliflower
Fresh, frozen, or pre-packaged cauliflower rice all work well in this recipe.
Fire-Roasted Tomatoes
Fire-roasted tomatoes add a little smoky depth. For a milder flavor, substitute regular diced tomatoes.
Onion and Bell Pepper
These provide the classic flavor base found in many Mexican and Spanish-style rice dishes. Use red, yellow, orange, or a combination of peppers.
Jalapeño or Serrano Pepper
Adds heat and flavor. For a milder dish, remove the seeds and membranes before chopping.
Garlic
Fresh garlic adds depth and rounds out the spice blend.
Spices
Chili powder, cumin, and oregano give this cauliflower rice its signature Mexican-inspired flavor. Salt and pepper bring everything into balance.
One tiny Lindy tweak: I'd consider adding:
"Do not use green bell peppers here." Their stronger vegetal flavor can overpower the other ingredients and change the character of the dish.
Fresh, Frozen, or Pre-Packaged Cauliflower Rice?
The good news is that all three work well, so use whichever is most convenient.
Fresh cauliflower rice
Offers the best texture and freshest flavor. It stays slightly firm when cooked and is usually the most economical option if you're willing to do a little prep work.
Frozen cauliflower rice
A convenient option that cooks quickly. Because freezing releases moisture, it may be a bit softer and can benefit from a few extra minutes of cooking to evaporate excess liquid.
Pre-packaged cauliflower rice
The ultimate convenience choice. It generally cooks similarly to fresh cauliflower rice and eliminates all the prep work, though it is often the most expensive option.
My Recommendation
If I have the time, I prefer fresh cauliflower rice for its texture and flavor. But honestly, once it's cooked with tomatoes, peppers, garlic, and spices, all three options make a delicious side dish.
Step-by-Step Instructions (Using Fresh Cauliflower)
- Rice the cauliflower
Remove the green leaves from the cauliflower and cut it in half. Half a head of cauliflower will make enough cauliflower rice to serve about four as a side dish. Save the remaining half for another use.
- Roughly chop the half head of cauliflower into florets.
- While a box grater works, I find a mini food processor much easier
- Pulse the florets using short on-and-off bursts until the cauliflower resembles rice-sized pieces.
Cook the aromatics
Heat a teaspoon of olive oil in a large sauté pan over medium heat.
Add the onion, bell pepper, jalapeño, and garlic. Cook, stirring occasionally, until softened and fragrant, about 4 to 5 minutes.
Add the cauliflower and spices
Stir in the riced cauliflower, chili powder, cumin, and oregano. Cook for 2 to 3 minutes, stirring to evenly distribute the spices.
Finish the cauliflower rice
Add the fire-roasted tomatoes and their juices. If the mixture seems dry, add a splash of water.
Reduce the heat to medium-low and cook for 7 to 10 minutes, stirring occasionally, until the cauliflower is tender but still has a little bite.
Taste and adjust with salt and pepper before serving.
Cooking Method(s)
The cooking method remains the same whether you're using fresh, frozen, or pre-packaged cauliflower rice.
The biggest differences are moisture and cooking time.
Fresh cauliflower rice generally cooks the quickest and stays firmer.
Frozen cauliflower rice may release extra moisture as it cooks and can require a few additional minutes to evaporate the excess liquid.
Pre-packaged cauliflower rice cooks similarly to fresh and offers the convenience of no prep work.
For the best texture, cook just until tender and avoid overcooking, which can make the cauliflower soft and watery. 🌶️🍅🍚
FAQs
An average 2-pound head of cauliflower yields about 6 cups of cauliflower rice, enough for two batches of this recipe or several side dish servings.
Yes. White, orange, purple, and yellow cauliflower all work well in this recipe.
Keep in mind that once combined with tomatoes and spices, most of the color differences become much less noticeable, so I usually choose whichever cauliflower looks best or is priced best.
Not always. Cauliflower rice works beautifully in recipes where rice is primarily a flavor carrier, such as stir-fries, burrito bowls, and this Mexican-style cauliflower rice.
Because it doesn't absorb liquids the way traditional rice does, it's less suitable for dishes that rely on rice soaking up broth, gravy, or sauces.
Cauliflower rice is lower in carbohydrates and calories than traditional rice while adding an extra serving of vegetables to your meal. It's a great option when you want the flavors of a rice dish in a lighter form.
Variations
Turn Up the Heat
Add red pepper flakes while cooking or substitute some or all of the jalapeño with serrano or habanero peppers.
Make It Milder
Use regular diced tomatoes instead of fire-roasted tomatoes and remove the seeds and membranes from the peppers.
Add More Vegetables
Roasted corn adds sweetness and texture, while diced zucchini or yellow squash blend naturally into the dish without overpowering the Mexican flavors.
Finish with Fresh Herbs
A sprinkle of chopped cilantro and a squeeze of lime juice brighten the flavors just before serving.
Storage
Fresh Cauliflower Rice
Store uncooked cauliflower rice in an airtight container in the refrigerator for up to 3 to 5 days.
Cooked Cauliflower Rice
Store leftovers in an airtight container in the refrigerator for up to 4 days.
Freezing
Cooked or uncooked cauliflower rice can be frozen for up to 6 months. Store in freezer-safe containers or bags and remove as much air as possible to prevent freezer burn.
Reheating
For the best texture, reheat cauliflower rice in a skillet over medium heat rather than the microwave. This helps evaporate excess moisture and keeps the cauliflower from becoming soggy.
