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 🙂

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)
