Yup...totally easy and utterly wonderful. I hardly ever do anything with cauliflower anymore except roast it...and the garlic cloves add a lovely mild garlicy flavor to these. Thanks for posting!
I baked at 450 for 30 minutes, turning only once after 20 minutes. I also used just one head of garlic and lightly crushed the cloves. It's very good.
So good! The only thing I did differently was to use garlic salt rather than regular salt. It was so easy and the flavor was great. We really enjoyed them.
