This is my absolute go-to recipe when having a family Sunday roast. The garlic butter is superb and I LOVE the lemon and mustard.

So true Carol. I’m cooking the whole head of cauliflower from now on. Can’t wait to try it.

I love roasting cauliflower whole. I wrap the cauli, leaves & all, in foil, place on a tray & bake. Once cooked, I serve straight from the tray drizzled with a little olive oil & seasoned with salt & pepper. Pretty plain, but tasty. I can't wait to try your version!

This is a recipe that everyone needs to try, it tastes absolutely HEAVENLY! I've had roasted cauliflower before, but cut into florets and only with a little olive oil and garlic added. Your method of whole roasting is genius and your herb butter is AMAZING! Given the minimal ingredients and the ease of making it, I can't believe how beautiful this tastes with the herb butter, thank you for a great recipe 🙂

Thank you, what a lovely review.

We are going to put it in the kettle roaster. So looking forward to it! My husband isn't LCHF but he was the one who wanted to try it!

Also I rly like cauliflower roasted as florettes with sliced onions (and maybe broccoli). Drizzle olive oil over and then salt & pepper to taste. Stir every so often till browned. Just a change of pace for those looking for more ideas.

I made a roasted cauliflower today (with a tahini dip smeared all over it). I did it at 400F for an hour. It still wasnt rly done. Next time I will cut it in half and put it flat side down on a buttered or oiled pan to roast it. If ur interested here's the dip recipe:
1/2c tahini
1-2cl garlic, minced
1/4-1/2tsp cumin
1/2tsp salt (my tahini was unsalted)
pepper to taste
1/2 large lemon, zest and juice
some olive oil to thin it -- optional, I didnt use it but next time I will
It tasted incredibly like hummus! YAY a hummus substitute (i miss beans and bean dips lol)
