The BEST Cauliflower Recipe

I don’t know who discovered roasting vegetables and made it mainstream but I want to hug them. I absolutely would choose any vegetable over fruit, but I still don’t love eating my veggies. A sure-fire way to get me to eat almost any vegetable is to roast it.

Cauliflower, like Brussels sprouts, is kind of an acquired taste, I think. It’s a strong flavor that not everyone loves. I know I did NOT like it growing up at all. I always said I didn’t like it and avoided it like the plague until I tried it roasted. Then I became a cauliflower convert!

Of all the cauliflower recipes, roasted cauliflower is my favorite!

Where and how to buy cauliflower

You can buy cauliflower in any grocery store. Make sure that the white florets are white and free of any dark spots or mushy areas. Fresh cauliflower will keep up to a week in the refrigerator if you buy it at the right time, so be sure to inspect it before buying.

How do you cut and prepare cauliflower for roasting?

The stem of a cauliflower is hard to work around. I like to cut the head in half and then cut off as much of the thick stem as possible before slicing the florets. Once the stem is dealt with, you cut or break the cauliflower into florets much like broccoli.

They sell cauliflower already sliced (or even riced!) in the prepared foods aisle. Those are perfectly fine to buy, just be sure to check the dates for the freshest produce. Those packages have a sneaky way of being outdated!

Once the florets are sliced, wash them well and then drain.

How do you roast cauliflower?

It’s simple to do:

  1. Decide on your seasonings.
  2. Line a cookie sheet with aluminum foil for easy clean up (optional) and spray it with nonstick cooking spray.
  3. Place the cauliflower in a single layer on the cookie sheet.
  4. Bake in a preheated 400°F oven, rotating the pan and stirring it once or twice, until the cauliflower is nice and golden. This will take 25-30 minutes, depending on the size of your florets.

How to season this roasted cauliflower recipe

Vegetables taste better with tons of seasoning! Salt and pepper are fine but adding herbs and garlic and parmesan just make the meal more enjoyable. This recipe uses:

  • Onion
  • Garlic
  • Salt
  • Pepper
  • Parmesan

I love adding parmesan cheese to veggies – it makes them so good. Just be sure to get the grated parmesan (i.e. from the green canister), not the shredded kind.

  1. You know what’s even better? Use nutritional yeast instead of parmesan. Less calories, no fat, cholesterol, sodium or lactose. It tastes exactly the same.
