What is Mexican rice?

Mexican rice, also known as Arroz Rojo, red rice or Mexican-style Spanish rice, is a classic and beloved Mexican side dish. It’s traditionally made by sautéing rice with tomatoes, onions, garlic and aromatic seasonings until golden brown in color and fluffy in texture.

What’s cauliflower rice Mexican?

Mexican cauliflower rice has the same bold flavor as traditional Mexican rice – it just replaces long grain white rice with healthier cauliflower rice.

Are Mexican rice and Spanish rice the same?

While some people will refer to Mexican rice as Spanish rice, they are not one in the same!

Spanish rice, also known as paella, is firm in texture and yellow in color from the addition of saffron. Meanwhile, Mexican rice is reddish in color and soft with a moist, melt in your mouth texture. Also, while Spanish rice includes saffron, Mexican rice does not and instead it includes cumin.

How is Mexican rice cauliflower seasoned?

The exact seasonings in Mexican rice can vary greatly depending on region and family tradition. However, most authentic Mexican rice recipes are seasoned with at least fresh garlic and either tomato bouillon (also known as Caldo de tomate), tomato paste, or tomato sauce. Variations can also include chili powder, cumin, oregano, cilantro and lime juice.

Is it spicy?

Traditionally, Mexican rice is not overly spicy or hot. Authentic Arroz Rojo is fluffy in texture and complex in flavor with delicate notes of tomato and a bold, slightly piquant punch.

You can easily customize this healthy red cauliflower rice to be spicier or mellower in flavor! If you prefer a lot of fiery heat, you can add lots of fresh chili peppers. Or, if you prefer a milder flavor, you can omit the peppers and chili powder entirely and substitute red bell pepper instead!

Why is Mexican cauli rice red?

Traditional Mexican red rice gets it characteristic reddish-orange color from the addition of tomatoes. Depending on the region and family recipe, the reddish color and tomato flavor can come from either tomato bouillon, tomato puree or tomato paste.

What ingredients are in cauliflower Mexican rice?

The ingredients in traditional Arroz Rojo can vary greatly depending upon the region and family tradition. Most traditional recipes use the same basic ingredients as a base, such as rice, tomatoes, onions and chicken broth or stock.

This healthy Mexican rice cauliflower is a modern take on Mexican rice and substitutes the white rice with cauliflower rice. This recipe also utilizes more vegetables for a boost of nutritional goodness!

Ingredients in this recipe

• Cauliflower: You will need one large head of cauliflower to transform into rice. If you want to save time and energy on prepping, you can purchase cauliflower rice in the produce section of most major grocery stores.
• Onion: One small yellow onion adds a touch of mild onion flavor.
• Peppers: Fresh chili peppers provide a little heat! I like to use mild jalapeño peppers, slightly spicy serrano peppers or a mix of the two. If you prefer a very mild pepper flavor, make sure you remove most (or all) of the ribs and seeds from your peppers before dicing.
• Garlic: Two to three cloves of garlic provide a subtle, yet distinctive punchy taste. Make sure you use fresh garlic, not the minced variety sold in a jar!
• Spices and Seasonings: A combination of ground cumin, smoked paprika, chili powder, kosher salt and ground black pepper all provide a tons of flavor!
• Tomato Paste: Two tablespoons of thick tomato paste give the rice that traditional red color while also adding a highly concentrated tomato flavor.
• Corn: Corn adds plenty of sweet flavor and juicy texture! You can use fresh, frozen or canned corn depending upon your preference and if corn is in season! (See below for types of corn you can use)
• Tomatoes: Roma tomatoes add delicious, juicy pops of tangy, garden-fresh flavor!
• Stock: 6 tablespoons of stock help soften and cook the cauliflower rice. You can use chicken or vegetable stock depending upon your personal preference or what you have on hand.
• Cilantro:  Fresh cilantro adds a ton of earthy flavor! If you aren’t a fan of cilantro you can substitute parsley or scallions!
• Lime Juice: Fresh lime juice adds a bit of acidity. Make sure you purchase limes and squeeze them yourself for the best flavor!

Substitutions, variations and toppings

Looking to make a few changes or additions to this cauliflower mexican rice recipe? No problem! This recipe is super flexible and incredibly easy to customize! Get creative in the kitchen – eliminate any ingredients that you don’t have on hand or simply don’t like and replace them with ones you love! Below are a few ideas to help get you started!

Substitutions

• Corn: You can use any type of corn you have readily available! Fresh, frozen or canned corn all work great in this recipe. I like to use leftover grilled corn (cut off the cob) when fresh corn is in season during the summer. If you use frozen corn, make sure you defrost it before proceeding with the recipe. If using a can of corn, make sure you drain it thoroughly first. Looking to keep this mexican cauli rice low-carb? You can omit the corn completely or substitute it with your favorite fresh vegetable (see below for ideas)!
• Tomatoes: Are fresh tomatoes not in season? No worries – substitute a can of diced tomatoes instead, just make sure you drain the tomatoes first! Or try using your favorite salsa instead of tomatoes!
• Peppers: Not a fan of spicy chili peppers? Try substituting bell peppers instead! I love sweet red or yellow bell peppers in this recipe, but green bell peppers work fabulously as well!
• Vegan-option: Looking to make this vegan? Simply substitute the stock with vegetable broth!

Optional additions

• Beans: Want to add some plant-based protein? Toss in a can of your favorite beans along with the corn in step 2 of the recipe. Make sure you thoroughly drain and rinse the beans prior to using!
• Chicken: Prefer a lean, complete protein? Stir in some shredded rotisserie chicken before serving!
• Carrots: Give your rice a boost of β-carotene by adding carrots to the mix! Finely dice your carrots and add them to the pan when you add the peppers!
• Peas: Love sweet peas? Try adding a few handfuls when you add in the corn!
• Zucchini: Need to use up all that summer-fresh zucchini? Shred your zucchini and gently squeeze out all excess moisture before stirring it into the rice in step five!

Toppings

• Dairy: A generous dollop of sour cream or Greek yogurt is the perfect creamy compliment to this cauliflower rice Mexican!
• Avocado: Buttery slices of avocado are a wonderful way to add healthy fats!
• Cheese: I’ve never met a dish that didn’t benefit from a generous sprinkling of cheese! To keep things authentic, try using Cotija or Queso Fresco!
• Salsa or Pico de Gallo: Topping your rice with your favorite salsa or fresh pico de gallo is a great way to enhance that juicy, fresh tomato flavor!
• Hot Sauce: I like to bring the heat, so a few dashes of Mexican hot sauce is a must for me!

How to rice a head of cauliflower?

Turning cauliflower into rice is so incredibly easy! There are two different techniques for making cauliflower rice at home, depending upon your preference and what kitchen equipment you have readily available. You can use either method to make this riced cauliflower Mexican rice. Or simply use store-bought cauliflower rice to keep things quick and easy.

• Food Processor (pictured below): Personally, I prefer to make cauliflower rice using the food processor. I find the process much quicker and easier. To make cauliflower rice using the food processor, cut your head of cauliflower into florets. Next, add the florets to the food processor in batches. Pulse the cauliflower until it resembles rice. Alternatively, you can use the grater blade (S Blade) attachment to blitz the cauliflower into small pieces. I typically don’t use the grater blade, because it’s just one more thing to clean!
• Box Grater: If you don’t have access to a food processor, you can easily use a box grater to make cauliflower rice! Cut the head of cauliflower into large chunks and use the medium-size holes on the box grater to grate the cauliflower into rice.

Storage: After ricing the cauliflower, transfer it to a resealable bag and store it in the refrigerator or freezer.

Pro-tip: Fresh cauliflower rice will keep in the refrigerator for up to 4 days; however, I recommend storing it for no more than 1-2 days. Upon storage the cauliflower rice will start to develop a strong sulfur smell, so it’s best to use it right away or within the first 2 days.

How to make Mexican cauliflower rice?

This healthy cauliflower Mexican rice recipe is so simple to prepare! This recipe requires just one pan, a few easy-to-find ingredients and 15 minutes of active cook time!

1. Prep cauliflower: On a clean work surface, cut the cauliflower into 1-inch florets. Working in batches, add the florets to a food processor or standing blender. Pulse until the cauliflower florets resemble rice, about 8-12 pulses. Transfer cauliflower ‘rice’ to a large bowl and continue to process remaining florets. Set the bowl of cauliflower rice to the side.
2. Sauté the vegetables and seasonings: Heat the oil in a large saucepan over medium heat. Once the oil is shimmering, add the onion, jalapeno, salt and pepper. Cook, stirring frequently, until the onions are soft. Add the garlic and seasonings. Stir and cook until fragrant. Add in the tomato paste and cook, stirring frequently, until tomato paste is fragrant, about 1-2 minutes. Add the cauliflower, corn and tomatoes. Cook, stirring, for 2 minutes.
3. Add the liquid and cook covered: Add the stock and season to taste with salt and pepper. Stir to combine. Cover the pan and reduce heat to medium-low. Cook for 4 minutes.
4. Uncover and continue to cook: Uncover the pan and continue to cook, stirring occasionally, until the cauliflower is tender about 4-5 minutes.
5. To serve: Remove pan from heat and stir in fresh cilantro. Taste and adjust for seasoning with salt and pepper. Serve with lime wedges and optional garnishes on side. Enjoy!
