How to select the perfect cauliflower

When selecting your head of cauliflower, make sure to avoid crumbly florets, brown spots, and dull color. The outer leaves should look fresh and a beautiful, vibrant green.

If you buy them already pre-cut, select pieces with no discoloration.

Roasting tips and step-by-step instructions on how to make this roasted cauliflower recipe

I love cauliflower and how easy they are to be prepared.

Preheat the oven to 400F

  • Start by removing the florets from the tronc of the cauliflower.
  • Split large florets into bite-size pieces so they can be easier to eat.
  • Toss the florets with love oil and place them on a rimmed baking sheet.
  • Please place them in the preheated oven and bake until browned and crisp.

Meanwhile, prepare the vinaigrette by mincing or grating the garlic, whisking it with lemon juice, a splash of olive oil, and a dash of salt.

  • Once the cauliflower florets are done, mix them with the vinaigrette and serve.

This roasted cauliflower recipe can be enjoyed warm or at room temperature.

The garlic in the lemon dressing is a great addition to it. However, it can be omitted if you wish.

Chef Tip

Mincing or grating the garlic? I prefer grating as, to me, the natural oil and flavor of the garlic are intensified and mixed well with the lemon and oil, but I do not have chunks of garlic when I bite into it.

Mincing is terrific, too, if you prefer a more pungent piece of garlic when eating it.

Variations and Substitutions

  • Add a few grinds of black pepper to the finished dish to add a kick of heat.
  • With all the selection of cauliflower at the market, you can make this recipe with orange or purple cauliflower.
  • Instead of cutting it into florets, you can slice the cauliflower into steaks and proceed with the recipe described below. Check for doneness, as every oven bakes differently.

Make Ahead, Storing and Reheating

Meal Prep: you can pre-chop your cauliflower up to two days before using it, cover and refrigerate. Add seasoning before roasting.

Refrigerate: once cooled to room temperature, store in an airtight glass container for up two days.

Reheating: It is not necessary to bring it back to room temperature when you are ready to enjoy it again. However, if you wish to eat it warm, you can reheat it on the stovetop or oven until heated.

Frequently Asked Questions

Is cauliflower a winter vegetable?

Yes, it is a very sturdy winter vegetable. Cauliflower loves the cold weather and is rich in Vitamin C.

What part of the cauliflower is not edible?

Every part of the cauliflower is edible, not only the florets but also the trunk. I recommend peeling the outer part before cooking it, as it will be tough.

Is it OK to eat cauliflower every day?

Everybody tolerates food differently, but too much cauliflower is known to cause some G.I. distress, such as gas and bloating. It would be best to drink plenty of water to help it move through your system.
