Roasted Cauliflower Recipe with Tomatoes

Oven roasted cauliflower is a great side dish for many meals but can lack flavor. This recipe includes red onion, tomatoes, cappers, and plenty of herbs to create a flavorful dish with an Italian feel.


Oven roasted cauliflower is one of my all-time favorite side dishes. The roasting process brings out the subtle sweetness of cauliflower. It gets soft yet a bit crispy. It is just so good!

But just roasting cauliflower alone is a tad, well, bland. And no one wants to eat dull and boring food.

So for this recipe, I up the flavor by adding in red onion, tomatoes, capers, and herbs!

These additional ingredients give this oven roasted cauliflower recipe an Italian feel and make the side dish disappear from plates!

My small boys, who are 4 and almost 1, love cauliflower roasted in the oven too! Though the oldest sometimes decides he doesn’t like the onions that are in this recipe.

Oven Roasted Cauliflower Recipe FAQ

How do you make sure the cauliflower is not soggy?

To have tender cauliflower with crispy edges, do not overcrowd the baking sheet. If there is too much on one pan, everything will steam instead of roast. Also, be sure not to use too much healthy cooking fat.

Can other herbs be used in place of Italian herbs?

Yes! Any single herb will work to make this roasted cauliflower recipe. I would suggest basil, thyme, or oregano.
