Callaloo Cook-up Rice is one of my family’s favorite quick cook-up rice dishes. So it made sense that it was one of the first cook-up rice dishes I attempted to make Whole30 compatible. This version of a Guyanese classic has all the notes of the original version—callaloo or spinach, pumpkin (calabaza squash) and coconut milk—but it’s grain free. The traditional rice is replaced with riced cauliflower but the flavor and texture is very similar to the original version of the dish which is always my aim when I remix a recipe!

Choosing the right riced cauliflower

For this recipe I used fresh store-bought riced cauliflower. The cauliflower bits are a bit larger and more forgiving. This gives a bit more wiggle room in the cooking process and allows the cauliflower to absorb a lot of the coconut milk for a greater flavor return in the finished dish. Check out my post on Coconut Cauliflower Rice to see my other favorite types of riced cauliflower and why I use different types for different dishes.

Choosing the right ingredients

For this recipe fresh ingredients are best but if you are like me and don’t always have access to fresh Caribbean or Guyanese ingredients frozen substitutions work just as well. Pictured above I have frozen pumpkin in place of the calabaza squash, you may also use frozen or fresh butter nut squash. I also have frozen whole leaf spinach instead of fresh callaloo. Using frozen, precut ingredients also eliminates some of the prep time which is always a win for me.

How to serve your Callaloo Cauliflower Cook-up Rice

I love serving my callaloo cauliflower cook-up rice with all of the usually trimmings for traditional Guyanese cook-up rice. Here I paired it with my Crispy Salmon Nuggets, some fried sweet plantains, pickled cucumbers and sliced tomatoes. And of course I can’t forget my steamed wiri wiri pepper. This is a complete, wholesome, nutrient dense meal and one that makes me feel a bit closer to home!
