How To Make Roasted Cauliflower with Olives

The hardest part (and it’s really not even hard), is cutting the cauliflower into florets. But like we said, it’s not really that hard. Just use a nice, large, sharp knife to carve out the core, and then cut away the florets. Easy!

In many well-stocked supermarkets, you can get pre-cut cauliflower. In a pinch, you can use frozen, although the texture will be very soft.

You may be asking: “Is cauliflower healthy?” In a word: Yes! Read more about that here.

The Ingredients You Will Need

This recipe is not only extremely pantry-friendly, but you can also adapt it to your own tastes.

Here are the simple ingredients we love using, but you feel free to adjust:

  • Fresh cauliflower, cut into florets
  • Extra-virgin olive oil
  • Lemon zest
  • Salt and pepper
  • Smoked paprika
  • Olives (we love a mixture of green and kalamata)
  • Capers
  • Fresh parsley
  • Grated Parmesan cheese

EXPERT TIP: The dish as written is 100% vegetarian. To make it 100% vegan, leave off the cheese.

Mix together the seasonings with the oil and lemon zest and then pour over the cut cauliflower in a large bowl.

This recipe will comfortably feed 4 people as a side dish. If you are feeding more, simply increase the cauliflower to 2 heads and add more olives as desired. The original flavored oil quantity will still work with the increased veggies.

Roasted Cauliflower FAQs

Can the dish be made ahead of time? Sort of. You can easily prep all of the items and get the oil mixture ready to go. We recommend serving the dish right from the oven, or soon after. The cauliflower, though still tasty, loses its nice crisp toasty texture after it sits for several hours.
What other ingredients can be added? For the holidays, we make this and add cooked pancetta (preferably cut into chunky pieces) and fresh sage. You can also add other vegetables, such as broccoli, carrots, and quartered new potatoes. They will bake in the same amount of time.
How long will leftovers keep? As mentioned, you’ll lose some of the toasty texture, but leftovers will keep covered in the fridge for several days. The dish doesn’t freeze very well, as the overall texture becomes compromised.

The combination of roasted ingredients makes for a gorgeous presentation, too!

All of the prep work can be done for the dish up to a day in advance.  Mix together the EVOO, seasonings, and lemon zest, and then keep covered in the fridge.  Do the same for the cut cauliflower.  Once ready to be baked, the recipe is extremely simple and quick. 
You can also add in cut broccoli, carrot spears or slices, and/or bell pepper strips.  During the holidays, we often add cooked pancetta (cut into small cubes) and fresh sage.
Leftovers will keep in the fridge for several days (though it's never as it is fresh out of the oven). We don't recommend freezing.

  • Something I’ve done with roasted cauliflower… take a full head, dip in a bowl of plain Greek yogurt (that I added a few Tbsp of yellow curry), and then broiled in the oven. Oh, drizzle olive oil over it before dipping into the curry yogurt. I think it did it for about 30 mins or so as per recipe…. It was amaze-balls!
