  • 4 cups medium-sized cauliflower florets
  • 1 teaspoon organic canola oil or a couple spritzes of oil spray
  • Pinch salt
  • 2 teaspoons lemon juice
  • teaspoon sumac Optional


  • TO ROAST CAULIFLOWER IN THE OVEN: Preheat oven to 425 degrees. Line a baking sheet with parchment paper. Put cauliflower florets on baking sheet. Toss them in oil and sprinkle them with salt. Then line them evenly across the baking sheet. If there is too much cauliflower on one sheet or if the florets are touching, they won’t roast as well. You want air between them, so that they can brown. Cook in oven for 25 minutes, stopping a couple of times to flip for even roasting.
  • TO ROAST CAULIFLOWER IN THE AIR FRYER: Put cauliflower florets in air fryer basket. Toss them with oil or spray them with a couple of oil spritzes. Add a pinch of salt. Air fry cauliflower at 400 degrees for 13 minutes, stopping a couple of times to shake the basket, so that the cauliflower can move around and roast in different places. Cauliflower floret sizes vary. So if the cauliflower doesn’t look quite done enough, cook for a few minutes longer.
  • Once the cauliflower is roasted in the air fryer or oven, move it to a bowl. Sprinkle on lemon juice. Toss the cauliflower, so that it’s evenly coated.
  • For a little added color, sprinkle the cauliflower with sumac (optional). Be aware that most sumac mixes have a little bit of salt in them. So be conscious of that when adding other salt to the dish.
  • Taste for salt, and add more if necessary.
