Using an oven to roast vegetables heats up your kitchen and is time-consuming. It can take up to an hour if you include the time to preheat your oven! Air frying cauliflower is so much faster and guarantees a bite that is tender on the inside, while perfectly crisp on the outside.

And with just a few simple ingredients you’re taking cauliflower from bland to super flavorful. You may already have everything you need to make the recipe!

Ingredients you’ll need

  • Cauliflower – the head should be firm and tightly closed, a medium-sized head feeds 4-6 people as a side dish. Did you know that cauliflower also comes in many different shades, including orange, green, and purple?
  • Oil – I use olive oil but any oil works, if you want to use less oil use an oil spray
  • Garlic – fresh garlic that is finely minced or garlic powder
  • Lemon juice – freshly squeezed tastes best but store-bought works too
  • Parmesan – I prefer to buy a big slab of parmesan cheese and freshly grate it

How to clean and prepare cauliflower

If you’ll be using a fresh head of cauliflower, you will need to remove the stalk and leaves and then separate the florets. The florets are the flowery part on the top of the stalk.

  1. Remove leaves – First, remove any leaves from the stalk. Just pinch them between two fingers and pull out and down, toward the base of the cauliflower.
  2. Remove stalk – Next, use a sharp knife to remove the stalk from the florets. Cut widthwise through the stalk about an inch or so below the florets. 
  3. Separate florets – Continue cutting and separating the florets until they are the size you want them. To ensure that everything cooks evenly, try to keep the florets as similar in size as possible.
  4. Clean – When you have the florets ready, transfer them to a strainer. Then, wash them thoroughly under cool tap water.
  5. Dry – Lastly, use either a clean kitchen towel, paper towels, or salad spinner to dry the cauliflower florets.

Variations

  • Curried – Try a curried version by adding 1 1/2 teaspoons yellow curry powder and 1/4 teaspoon ground cinnamon.
  • Breaded aka “deep-fried” – To make extra crispy cauliflower florets, season the florets with salt, pepper, and garlic powder. In a bowl combine 2 eggs and 2 Tbsp of water, toss the florets in the mixture then transfer to a bowl with about 1 cup of panko breadcrumbs. Follow the cooking instructions below.
  • Taco-style – Use taco seasoning instead of the spices listed below!
  • Air Fryer Buffalo Cauliflower – Season the florets with salt, pepper, and garlic powder before cooking and then when they are done toss in homemade (3/4 cup Franks Hot Sauce+1 tbsp melted unsalted butter) or storebought buffalo sauce. So yummy!

Recipe Tips and Notes

  • Toss the florets – Tossing the air fryer basket every few minutes while cooking prevents the cauliflower from cooking unevenly, and it ensures that the edges are nice and crispy.
  • Keep florets similar in size – While you won’t have completely identical sizes, try to use florets that are as similar in size as possible. This also ensures even cooking.
  • Save time – Instead of buying a whole head, you can also buy pre-washed, pre-cut cauliflower florets!
  • Use the whole cauliflower – Everything except the very bottom of the stalk is edible as well. So, save it for later if you want to. It’s perfect to use when you make soup, casseroles, and salads.
  • Separate before washing – Some people wash their cauliflower before they cut it, but I think it’s much easier to wash cauliflower after it’s been cut into florets.
  • Preheat – If the manual calls for it, preheat your Air Fryer. Some models need to be preheated, others don’t.

What to serve with this dish

  • Served as an appetizer – serve the crispy florets with your favorite dipping sauce just like chicken wings, e.g. blue cheese dip or aioli
  • Served as a side dish – this veggie dish goes well with any protein, like pork chops, chicken, or fish
