How to Make Oven Roasted Cauliflower

  1. Prepare: Preheat oven to 425°F. Set out a large rimmed baking sheet. Optional: line with parchment paper or aluminum foil for easy clean up. If starting with a cauliflower head, cut the individual florets into bite-sized pieces. If you’ve purchased a bag of florets, you will likely have large pieces and will want to cut small florets so that they all roast at the same rate.
  2. Toss: In a large mixing bowl, toss olive oil and salt with cauliflower.
  3. Roast: Spread cauliflower to a single layer on the prepared baking sheet. Roast in preheated oven for about 10-15 minutes, flip to avoid burning, and continue roasting for another 10 minutes (20-25 minutes total). When done, most pieces will have golden brown edges. The cooking time will vary depending on your oven and the size of the florets.

Recipe Tips for Best Results

  • Similar-sized pieces – Keep in mind that smaller pieces are more likely to burn and larger pieces may end up more firm. For the best results, try to cut the pieces so that they are the same size.
  • Add more vegetables! You can easily add halved brussels sprouts. If you’re a fan of roasted broccoli, add some broccoli florets. Super easy.
  • Make it crispy – If you have a convection oven or air fryer, you’ll get even better results than by roasting in the oven. The additional hot air blowing around will give you a wonderfully crisp edge.

Roasted broccoli tastes great alongside Oven Baked Rosemary Chicken or an Air Fryer Whole Chicken.
