Air Fryer Cauliflower From Frozen Recipe Tips

  • Keep it frozen until cooking: Don’t thaw the cauliflower before air frying; cooking it straight from frozen helps it crisp up better.
  • Light coating of oil: A drizzle of olive oil or avocado oil ensures a golden, crispy exterior without sogginess.
  • Season generously: Salt, pepper, garlic powder, paprika, or chili flakes add instant flavor; toss well before cooking.
  • Don’t overcrowd the basket: Arrange florets in a single layer so hot air can circulate, giving you evenly crisp results.
  • Shake halfway through: Toss the basket once or twice during cooking for uniform browning.
  • Adjust time for extra crisp: If you like more crunch, cook for an extra 2-3 minutes, keeping a close eye so it doesn’t burn.
  • Versatile serving options: Serve as a side, toss in sauces like buffalo or teriyaki, or add to salads and bowls.
