  • 2 heads of cauliflower
  • ¼ cup of olive oil or as much needed to coat all of the cauliflower
  • ¼ cup of harissa spice powder or harissa paste use more if needed
  • ¼ cup chopped garlic
  • salt to taste


  1. I first want to say that all of these ingredient measurements are adjustable. Depending on the size of your cauliflower you can use more of less of each ingredient.
  2. Preheat the oven to 350F. Cover 2 baking pans with aluminum foil (if you want cleanup to be easier, but you don’t have to cover the pans with foil if you prefer not to).
  3. Cut your cauliflower steaks (refer to my blog post above, or my cooking video, to learn how to cut the perfect cauliflower steak). Save the florets.
  4. Place the steaks on one baking pan and the florets on the other. Rub olive oil over them. Ensure all of the cauliflower is evenly coated.
  5. Rub the harissa powder or paste, chopped garlic, and salt all over the cauliflower until evenly coated.
  6. Cover the top of the pans with foil. I don’t suggest skipping this step because if you don’t cover the cauliflower it will take them a little longer to cook and the outside of the cauliflower might get browned quickly and cook faster than the inside.
  7. Cook the cauliflower florets for about 20 – 25 minutes and remove them from the oven. Cook the steaks for 30 – 35 minutes, depending on the size and thickness of your steaks the time could be slightly more or less. The steaks are done when you can easily stick a fork in them. They should not be very soft and mushy.
  8. This next step is optional. Place the oven on broil and broil the steaks until they are golden brown on the outside, about 5 minutes more or less. Flip the steaks and broil the other side until browned. 

  9. There might be bits of paste and garlic on the baking pan. I like to scoop this up with a spoon and rub it over the hot steaks and florets as soon as I remove them from the oven.   Serve

Recipe Notes

Instead of plain chopped garlic, I used my homemade spicy chili-garlic paste because I like EVERYTHING spicy (recipe coming on the blog soon)!
