Not long ago I updated the recipe for Roasted Cauliflower with Parmesan and that reminded me about how simple and delicious roasted cauliflower is. And it’s pretty obvious that I am a roasted cauliflower fan, because back in the archives I have a lot of variations of roasted cauliflower. This Low-Carb Roasted Spicy Cauliflower is a roasted cauliflower recipe that recently got popular on Pinterest, and I was happy to update the original photos that I felt didn’t really show off how tasty it was. If you like spicy food and are a cauliflower fan, this might become one of your favorite ways to cook it!

I originally found the recipe for Roasted Spicy Cauliflower in The South Beach Diet Quick and Easy Cookbook (affiliate link) back in 2007, and the  original recipe simply called for red pepper flakes. Although I had a few different types in my pantry, I was excited to use the Aleppo Pepper that Burcu from Almost Turkish Recipes sent me as a gift when we were doing a blog event together called Weekend Herb Blogging.

Burcu described Aleppo Pepper as Turkish flaked hot red pepper and said “You can use this semi moist, delicious smelling, hot, flaked red pepper while cooking or sprinkle it on your foods.” I loved the Aleppo pepper and found it to be seriously addicting. Now flash forward quite a few years and I’ve been to Turkey where I stocked up on Aleppo Pepper, and you can also buy Aleppo Pepper from Amazon.com (affiliate link). I love making this recipe with Aleppo pepper, but just use another type of spicy red pepper to make this if you don’t have that and don’t want to buy it.

What ingredients do you need for this recipe?

  • large head cauliflower
  • olive oil
  • red pepper flakes; I would use Aleppo Pepper but use any red pepper you have
  • salt
  • fresh ground black pepper to taste
