We’re hooked on roasted cauliflower. It’s sweet, nutty and so easy to make. Perfect as a side, for topping pastas or eaten as a snack. We’re even thinking that it might convert a few anti-cauliflower cooks out there. (Fingers crossed).

How to Roast Cauliflower in the Oven

Roasting is one of our favorite ways to cook cauliflower — in fact, we love this method so much that we’ve used it to make spicy roasted cauliflower, buffalo roasted cauliflower wings, and a Thai curry roasted cauliflower.

Start by cutting the cauliflower into florets then toss them onto a large baking sheet, add a little olive oil, salt, pepper and some thyme — fresh or dried thyme work. Slide the cauliflower into a hot oven — we go for 425 degrees Fahrenheit — and roast, turning once until the florets have caramelized a little on all sides. It takes about 30 minutes.

When the cauliflower is browned in places and tender in the middle, we toss a handful of parmesan cheese on top, and then slide it back into the oven for an extra 5 minutes. The cheese melts and browns a little — so delicious.

Then, just before serving we scatter lemon zest and a spritz of lemon juice on top. The lemon brightens the dish up and works so well with the sweet nutty flavor of the cauliflower.

    Incredible recipes, right up my alley!! Thank you

  • Sheila October 13, 2017, 5:47 pm

    Is there a way to prepare this a day in advance? Would it reheat well?

    • Joanne November 6, 2017, 7:27 pm

      Hi Shiela, I love this as leftovers, but keep in mind that the cauliflower will be less crisp on the outside. You could always throw them back into a hot oven to crisp up slightly, though.

    I am allergic to citrus, therefore, I cannot have the lemon. I want to make this and wondered how much leaving the lemon out would change the taste. Also is there anything I can substitute in place of lemon in so many recipes or just leave it out?

    • Joanne May 19, 2016, 1:24 pm

      You can simply leave it out or try a dash of apple cider vinegar or balsamic.

    This method of preparing cauliflower is outstanding. Naturally we all have our own special touches. Mine is to use lemon olive oil and salt and that is all. If I have time a bit of lemon zest is wonderful, but anything else is overkill for this amazing veggie.

    oooh, delicious! made it tonight and the whole family loved it. took your suggestion and used curry powder instead of thyme, and also added a sprinkle of crushed almonds when i added the cheese. many thanks.

    We’ve just discovered roasting vegetables and we are so in love with them. We’ve done carrots, asparagus, brussel sprouts, onion and sweet potato, but we haven’t done cauliflower yet, but after reading this we definitely will! Thanks
