I’ve tested frozen vegetables in the air fryer a LOT, and cauliflower holds up surprisingly well as long as you don’t overcrowd the basket.

Ingredients Needed for Air Fryer Frozen Cauliflower

• 1 bag frozen cauliflower florets (12–16 oz) – no need to thaw
• 1–2 teaspoons olive oil spray – helps with browning
• ½ teaspoon garlic powder – for flavor
• ½ teaspoon onion powder – optional but good
• Salt and pepper to taste

Optional Add-Ins

• Red pepper flakes
• Grated parmesan
• Buffalo sauce (add after cooking)
• Garlic Seasoning Salt

Substitution Tips

• Use avocado oil spray instead of olive oil.
• Skip oil completely for a zero-added-fat version (it won’t brown as much, but still works).
• Use taco seasoning for a Mexican-style side.
• Add nutritional yeast instead of parmesan for a dairy-free option.

How to Cook Frozen Cauliflower in the Air Fryer

Preheat air fryer to 400°F (if your model requires preheating).

Add frozen cauliflower directly to the basket. Spray lightly with olive oil spray.

Sprinkle with garlic powder, onion powder, salt, and pepper.

Air fry for 12–15 minutes, shaking the basket halfway through.

If you want it crispier, cook an additional 2–3 minutes.

That’s it.

No thawing. No draining. No patting dry.

How to Get Crispy Frozen Cauliflower

This is where most people go wrong.

Do not overcrowd the basket.
If the cauliflower is stacked too tightly, it steams instead of crisps.

For best results:

• Cook in a single layer.
• Shake halfway through.
• Don’t over-spray oil (a light mist is enough).

If you love extra crispy edges, let it go a minute or two longer at the end.

Low Point WW Tips

If you're following Weight Watchers, this recipe is extremely flexible.

Here’s how to keep it low point:

• Use olive oil spray instead of pouring oil (0 points for most plans when lightly sprayed).
• Skip parmesan cheese or measure carefully.
• Season heavily with spices instead of sauces.
• Pair with zero-point proteins like grilled chicken breast or eggs.
• Toss with hot sauce instead of creamy dips.

Estimated WW Points (per serving, serves 2):

• Cauliflower alone: 0 points
• With light olive oil spray: 0 points (depending on plan)
• With 1 tablespoon parmesan added: 1–2 points per serving
