This Roasted Spicy Cauliflower is a recipe that got popular on Pinterest a few years back, so I updated the original photos that didn’t show off how tasty it was. At first the recipe simply called for red pepper flakes, and I had a few different types in my pantry. But when I updated the photos 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.

And Aleppo Pepper is something I always have on hand now, but use any spicy red pepper flakes you prefer if you don’t have Aleppo Pepper. And if you like the idea of spicy roasted cauliflower, this might become one of your favorite ways to cook it; I hope you will try the recipe!

And it’s obvious that I’m a roasted vegetable fan, and I think any kind of vegetable baked on a sheet pan is the perfect winter side dish. And not long ago I updated this other cauliflower recipe, it reminded me again in a big way just how simple and delicious roasted cauliflower really is!

What is Aleppo Pepper?

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 went to Turkey where I stocked up on Aleppo Pepper. You can also buy Aleppo Pepper from Amazon.com (affiliate link), but use any type of spicy red pepper flakes you prefer.

How spicy is the Roasted Spicy Cauliflower?

This recipe calls for one teaspoon of red pepper flakes, which is enough to make it moderately spicy. If you’re not sure how much spiciness you want, you can use less and add more red pepper at the table.
