This Keto Spanish “Rice” is the perfect low-carb replacement for traditional Spanish rice — fluffy, flavorful, and never soggy. The secret is dry-cooking the cauliflower first to remove excess moisture before adding any tomatoes or seasoning.
This recipe is easy, budget-friendly, and made with simple ingredients you can keep on hand. It pairs perfectly with taco bowls, fajitas, burrito bowls, or any Mexican-inspired keto dinner.
This keto Spanish “rice” pairs especially well with hearty dishes like my Keto Ranch Chicken Chili, adding a flavorful low-carb side to a comforting meal.
Why This Method Works
Most cauliflower rice recipes turn mushy because moisture isn’t cooked off first. Instead of adding everything at once, this recipe uses a dry-cook step to evaporate excess water before seasoning. That’s what gives you a texture that’s surprisingly close to real rice.

Ingredients
- 1 tbsp olive oil or avocado oil
- 1 small onion, finely diced
- 2 cloves garlic, minced (or 1 tsp minced garlic)
- 2 bags frozen cauliflower florets, riced
or 1 whole head of cauliflower, riced - 1 (10-oz) can Rotel tomatoes, very well drained
- 1–1½ tsp my Homemade Taco Seasoning
- ½ tsp ground cumin
- Salt, to taste
- 1–2 tbsp tomato paste (optional, for deeper color and flavor)
- 1–2 tbsp chicken broth or water (only if needed)
Instructions
- Rice the Cauliflower. If you’re starting with frozen cauliflower instead of pre-riced, add it to a food processor and pulse just a few times until it resembles rice. Don’t overprocess — you’re aiming for a rice-like texture, not mashed cauliflower.
- Sauté the aromatics. Heat oil in a large skillet over medium heat. Add the diced onion and cook for 3–4 minutes until soft and translucent. Add garlic and cook for about 30 seconds, just until fragrant.
- Dry-cook the cauliflower. Add the riced cauliflower by itself. Cook uncovered for 10–13 minutes, stirring occasionally, until steam has evaporated and the cauliflower looks fluffy and dry.
- Tip: This step is critical. If the cauliflower still looks wet, keep cooking — moisture is the enemy of good keto “rice.”
- Add seasoning and tomato base. Sprinkle in taco seasoning, cumin, salt, and tomato paste (if using). Stir until the cauliflower is evenly coated and fragrant.
- Add Rotel. Stir in the very well-drained Rotel tomatoes. Cook another 3–4 minutes until heated through and no excess liquid remains.
- Adjust texture only if needed. If the rice looks too dry, add 1 tablespoon of broth or water at a time until desired texture is reached.
- Finish and serve. Serve as-is, or finish with a small pat of butter, fresh lime juice, or chopped cilantro.
