Expert tips

  • Preheat the air fryer by following the defrost settings of your air fryer, as all air fryers are programmed differently.
  • Cook frozen cauliflower straight from the fridge into the air fryer — no need to defrost them.
  • It’s ok to have a little overlap, as long as you don’t overcrowd the air fryer basket.
  • Shake the basket or flip the florets halfway through to make sure they crisp evenly.


  • If you prefer an extra crispy variation, you can make frozen breaded cauliflower by coating the frozen florets with starch or flour of your choice.
  • Change up the seasonings to suit your tastes! For example, toss frozen cauliflower wings in buffalo sauce (hot sauce and nutritional yeast), to make finger-licking air fryer buffalo cauliflower from frozen.
  • Top it off with a tablespoon of grated parmesan cheese for a savory finish.
  • Make it a tad spicy and dip them in highly flavored garnishes, like the versatile, sweet and sour Thai chili sauce, or the smoky sweet, Chinese-flavored garlic chili sauce.
  • Serve it alongside shacha sauce for an umami-forward variation of air fry frozen cauliflower.
