We have tried and tried to do cauli-rice and neither of us can stand it, no matter what. We cheat and substitute brown rice, which does have a low glycemic index even though it’s not paleo. Sorry about that. But the recipe is amazing with it anyway!!
I just made Chile Verde today and made a big skillet of this to accompany! Truly my favorite cauli rice recipe out there!
Delishous as written! It went wonderfully with your Mexican beef recipe! Staple in our house!
Where has this been in my life?? This is so good. Spicy and perfect with taco bowls or just mixed in with different vegs. Will make this again and again.
Anyone know if this can store for a couple days? Or be frozen?
You can keep it in the fridge for up to 4 days.
why is this so high in carbs? I thought it would be low carb. How can I make it low carb as I’m eating low carb these days. thanks.
P.S. so enjoy your recipes.
10 grams of net carbs for a serving is pretty low carb.
what makes this so high in carbs for a 4 oz serving? I’m doing low carb these days, and this seems high. thanks. Really enjoy your recipes.
Absolutely wonderful. I’ve been looking for a go-to recipe to make cauli rice more interesting and this is a winner
First of all, thank you for calling it Mexican rice and not Spanish rice because we all know, Spanish rice uses saffron and it makes the rice yellow! I usually add the jalapeños after it’s cooked; nice little twist there. My little sping is that I add chicken broth for a little extra flavor and bake it! As always, love your recipes!!!
Hi Michele. I’ve been following your for a very long time and love your recipes. Thank you for this one as well.
I cannot do tomatoes. how much no-mato sauce do you recommend to replace the tomatoes and tomato paste in you recipe?
