Roasted Whole Cauliflower with Garlic Butter

If you’ve never thought about roasting the cauliflower instead of cooking it, you’re missing a lot! You won’t imagine how a simple recipe like this can have such an intense flavor. It could be served alone or as a garnish for other dishes.

The mini sized cauliflower is easier to prep and cook, but a normal sized one works fine as well, it’ll just take a little longer in the oven. This way of cooking is a tribute to the cauliflower, respecting its shape and texture, and we can salute it with the spices to our liking.

Never miss on any of this cruciferous vegetable’s fantastic health benefits anymore. A cup of cooked cauliflower provides around 73 of your vitamin C %DV, which is excellent! Moreover, the sulfur containing compounds and flavonoids which are considered non conventional nutrients are stacked in cauliflower, these help in your digestive, immune and cardiovascular systems. 

Speaking about vegetables, people often compare the benefits of raw versus cooked. In the case of cauliflower, it’s a win-win situation! If you decide to cook it, levels of some glucosinolates like sinigrin will decrease, but you will be getting approximately 12% of the recommended daily intake of folate which is of major importance in pregnancy.
