During December I’ll be sharing some of my favorite low-carb holiday recipes. My love for roasted cauliflower is well documented on the blog, and Roasted Cauliflower with Red Pepper, Green Olives, and Pine Nuts has great flavors.

And the colors in this recipe are so beautifully red and green, so I think it’s absolutely great for a holiday side dish! And with the colors and all the flavors going on here from red bell peppers, green olives, pine nuts, and capers, this is cauliflower at its finest; I promise anyone who loves roasted cauliflower will love this kicked-up version even more.

Roasted Cauliflower with Red Bell Pepper, Green Olives, and Pine Nuts

Yield 6 servings
Prep Time 10 minutes
Cook Time 35 minutes
Total Time 45 minutes

Roasted Cauliflower with Red Bell Pepper, Green Olives, and Pine Nuts is as good as it gets for a special side dish!


  • 1 head cauliflower, cut up into smallish, same-size pieces
  • 1 red bell pepper, stem and seeds cut out and cut into 1/2 inch dice
  • 2 T olive oil
  • salt and fresh ground black pepper to taste
  • 3 T pine nuts, or more (see notes)
  • 2/3 cup sliced green olives
  • 2 T capers
  • 2 T chopped flat-leaf parsley (completely optional, but if you have some it adds some nice green color)
  • cut lemon pieces to squeeze over (optional, but so good)


  1. Preheat oven to 425F/220C.
  2. Cut the cauliflower into smallish, same-size pieces and cut the red bell pepper into half inch dice. 
  3. Put chopped cauliflower and peppers into a plastic bowl and toss with 2 T olive oil, stirring so the vegetables are all lightly coated with oil.  Season to taste with salt and fresh ground black pepper and stir again.
  4. Spread the vegetables out in a single layer on a cookie sheet and roast for 20 minutes.
  5. While the cauliflower and peppers are roasting, slice the olives and measure out the pine nuts and capers.  Chop the parsley if using.
  6. After 20 minutes, remove cookie sheet from the oven, put the cauliflower and peppers back into the same bowl, and toss with the olives, pine nuts,  and capers.  
  7. Spread the mixture on to the cookie sheet again and roast an additional 10-15 minutes, or until the vegetables are starting to brown and the olive pieces are looking slightly cooked.
  8. Sprinkle with parsley if you're using it and serve hot, with a slice of lemon to squeeze over if desired.
  9. If you don't eat this all at once it will keep in the refrigerator for a day or two. I would reheat it in a very hot dry non-stick pan instead of using a microwave.


Slivered almonds would also be nice if you don't want to buy pine nuts.

  1. I made the roasted Christmas cauliflower for Christmas dinner and it was a hit. Tonight I’m taking it to a potluck dinner. Easy to make and absolutely delicious. I followed recipe exactly as written.

  3. This was good, I used California olives and enjoyed the flavor they added. Someone mentioned adding garlic cloves and I think that would go nicely with this dish.

  4. Such a gorgeous side dish! Perfect addition to any holiday menu!!

  5. My husband made this last night for dinner, except he hates olives so he used broccoli instead. It was delicious! One day when he's not around I'll make it with olives. 😉

  6. This may have to be a new addition to my Christmas dinner! So pretty and festive. 🙂

  7. Kalyn, do you think this would go well with a traditional Christmas Dinner (turkey, etc. etc)? JD

  8. Can you reheat in the micorwave? I want to bring to a Christmas potlouck.

    • I haven't tried reheating in the microwave, but truthfully I think the cauliflower will not be nearly as good that way. I'm saying that because in my opinion there's nothing quite like roasted vegetables right out of the oven. If you want a cauliflower dish that's good reheated, I would recommend Twice Baked Cauliflower.

      Or try this in advance and see what you think, maybe it will be better than I'm imagining.

  9. Can this dish sit out for over an hour

    • It won't hurt it all to sit as far as still being safe to eat. I am guessing it will still be good at room temperature, but I've only eaten it hot out of the oven or reheated.

  10. I love this, we make a similar version for sandwich spread.

  11. So glad you enjoyed it; just made this and took new photos so I'll be updating it soon.

  12. Me again :- ) I’ve had great fun with your recipe, such a great concept. You’ll see my own version here, Christmas Cauliflower. I made it all year last year … every version different!
