Ingredients/Variations

Cauliflower – Choose a heavy head of fresh cauliflower surrounded by thick green leaves. Remove leaves and rinse any dirt or debris from the head. Pat dry before seasoning.

Butter – We love the flavor of butter (of course) and the way it browns but olive oil works too.

Seasoning – Season the whole head of cauliflower any way you like! I keep it relatively simple with just a bit of parmesan cheese and garlic powder but this recipe lends itself well to your favorite seasonings and spices.

How to Roast a Whole Cauliflower

  1. Trim away the leaves, wash the cauliflower and trim the stem with a sharp knife.
  2. Place it in a Dutch oven and brush it with the remaining ingredients.
  3. Cover and bake (the steam helps cook it) until tender.
  4. Sprinkle with parmesan cheese & broil until browned & crispy.

  • Reheat by pan-frying slices, or mash or chop leftovers for soups, stews, or stir-fries.
  • Freeze portions wrapped tightly in plastic wrap and place them in a zippered bag for up to 1 month.

  1. I don’t usually comment on recipes I get, just jump to the recipe and see if I like it. Normally I rice it up and eat it raw, But I more or less used this recipe and it is AMAZING, thank you! Used garlic paste and grated lemon skin, that did it.

  2. Followed directions as written. Cauliflower was not cooked through after 30 minutes. I cooked it another 15 minutes. Finally had to finish broiling it and get it on the table as it was getting late for dinner. It was undercooked after 45 minutes. Not sure if it needed some liquid (water/stock) in the bottom of the pan or my cauliflower was too big and I should have cut it up in the pan before roasting? I probably could have cooked it for another half hour.2 stars

    1. Hi Tony, it is possible that your head of cauliflower was on the larger side. That would definitely result in it needing more time. But this recipe does call for it to be cooked 30 mins with tinfoil, and additional 15 without the foil, and then broiled at the end to finish off. So it does take close to an hour to fully cook.

  3. This is delicous. The seasoninings and especially the texture of the csauliflower (fully cooked, bur a little crispy)- yum!

    Mine did not brown well. First time to use this broiler, don’t believe it reached the right temper. It’s a keeper.5 stars

  4. The recipe says it takes 1 hour cooking time, but according to the instructions it says between 48-50 minutes. I just want to make sure that the instructions are correct: 30 minutes with foil, 15 minutes uncovered, and 3-5 minutes after the cheese is added. I have never made this before, but a lot of other recipes I’ve seen have a much longer cooking time. Thank you.
