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 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. 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.

Cut up a large head of cauliflower into individual florets and toss with olive oil, red pepper flakes, salt, and pepper. Spread it out on a baking sheet and roast at 400F/200C for 25-30 minutes, or until it’s softened to your liking and golden brown. Serve hot. That’s all there is to this easy recipe, but the flavor is really a WOW!

  4. these recipies sound so good

  5. Like you, I am a big fan of cauliflower, especially roasted, so bring on the recipes! I may try ordering Aleppo pepper on Amazon and give it a try.

  6. Looks delicious- I love cauliflower!

  7. This is my favourite way to eat cauliflower and in fact it’s the only way I can get my husband to eat it!

  8. Hi Pat,
    Fun hearing from you after all this time! Hope you're doing well.

  9. Hey, Kalyn, you'll never believe that I remembered this fabulous recipe from lo these many years ago because it was SO GOOD and I've lost my copy. I'm thrilled to find it here again. This one deserves an honorable mention on your front page to acquaint all your newer readers with its delicious healthy wonderfulness.

    Hope 2010 is treating you well!


  10. Kalyn – Yes, try Aleppo on tuna. I’ve done just Aleppo and salt, and I’ve also marinated with soy, sesame oil, garlic, ginger, etc and then sprinkled with Aleppo and sesame seeds before cooking. I’ve also added Aleppo to my falafel with great results. I think maybe I need to start my own blog to expound on this beautiful pepper.

  11. Pille, the bit of spiciness is great in this!

    Gattina, I’m betting the red pepper at the Turkish restaurant was the same as this.

    Tanna, great. You’ll love it.

    Jennifer, thanks for the feedback. I’m so glad you like it.

    Chigiy, I just adore roasted cauliflower in any form. This is just a great variation.

  12. I love roasted veggies, but I never roast cauliflower. This recipe will give me an excuse to try it. Thanks.

  13. We made the cauliflower recipe tonight, it was awesome! I was sorry that I only made half the head (as we were eating salad and chicken as well). I could easily sit and eat the whole dish. It was phenomenal, it will be going on my favorites list.

  14. I think I’ve found a local store that carries the Aleppo Pepper today!

  15. very interesting post Kalyn! I can’t tell the differences between different red peppers … my taste buds waving white flag… but your/Burcus discription brought me back some good memery when I dined at a Turkish restaurant 🙂

  16. I’ve roasted cauliflower with salt and pepper, and really loved it. Time to spice it up a little:)

  17. Vicki, I *love* the idea of using this pepper on Tuna. Will try it for sure.

    Bradley, try it. This was great.

    Deleted commenter: Sorry but I can’t allow people to leave links in my comments advertising other blogs or blog events. Once I do, I will be over-run with those type of comments.

    Chris, get some cauliflower ASAP!

  18. Looks fab! It is so weird because I have been seeing a bunch cauliflower recipes lately – all of a sudden! (I think I missed the memo and will run out to buy a head immediately.) It is just so yummy – Thanks for this recipe!

  19. Great looking recipe. I am always struggling to find new ways to add veggies to dinner. Cauliflower was never a nature go to veggie but the color looks great!

  20. Hi Kalyn –
    I got my Aleppo from Penzeys, and it’s my new favorite pepper. It’s especially good on seared ahi. I usually roast my cauliflower with garlic and then toss with parsley and parmesan, I’ll have to try it with the Aleppo.

  21. Asha, I bet cumin would be good on this. Will try it!

    Katie, I think Penzeys will mail anywhere in the world if you want to get some there. It might not be quite a great as what Burcu sent me, but there stuff is pretty good quality. Glad to hear you liked the chicken.

    HT (aka Lisa) You are soooo lucky to work close to Penzeys.

    Burcu, thanks for the offer to keep replenishing my supply. I do agree that it’s very special. I just love it. When I get home I’m going to edit and add the link you gave me, Thanks!

    Meeta, I really loved it.

  22. Yes! I love Cauliflower and am always on the look out for new and interesting recipes. Great one Kalyn.

  23. I almost forgot; i loved baked cauliflower recipe. Definitely try with red pepper.

  24. Kalyn, I’m gald you like the pepper. I’ll be back in Turkey this August and will absolutely bring you more, so no need to use them sparingly.
    Back in Turkey I had no idea how special pepper flakes were until I came here and could not find the same flavor. This site (http://www.savoryspiceshop.com/spices/chilurfa.html) says it’s the sweating process that gives isot pepper its unique flavor. Whatever it is, I love it. Thanks for writing about it!

  25. I’ll have to head over to Penzey’s at lunch and see if they have this pepper. Never had it but I’m always up for new spicy flavors!

  26. I’ve roasted cauliflower but never with red pepper! It looks delicious – such lovely color. Now, If I can only find the red pepper…..
    And I loved ‘Janet’s Mustard Chicken’

  27. Looks delicious Kalyn!!Throw in some cumin pd in there to make it even more flavorful!:))
