Ingredients for Garlic Parmesan Cauliflower
Below is a quick overview of the ingredients. Exact amounts are in the recipe card further down.
- Cauliflower – Fresh cauliflower yields the best texture when air fried.
- Oil, garlic powder, salt, pepper – Garlic powder adheres well and seasons evenly; you can use minced garlic if you prefer.
- Butter – Salted butter is used here; adjust seasoning to taste.
- Parmesan – Finely grated or powdered parmesan clings to the florets and creates a savory crust.

How to make Air Fryer Cauliflower
The method is straightforward and breaks down into a few easy steps for consistent results.
Preheat
Preheat your air fryer to 390°F (about 200°C) for a few minutes. Preheating helps the cauliflower brown more evenly.
Air Fry
Toss the cauliflower florets with a light spray of oil, then season with garlic powder, salt, and pepper. Air fry for 8 minutes, shake the basket, then continue cooking 5–7 minutes until the edges are crisp and the florets are tender.

Make sauce
While the cauliflower cooks, melt the butter and stir in the grated parmesan to form a thick, garlicky sauce. Keep it warm so it coats the florets easily.
Toss
When the cauliflower is done, transfer it to a bowl and pour the warm garlic‑parmesan sauce over it. Toss until every piece is coated. Serve right away for best texture.


Serve
This cauliflower makes a great low‑carb side. It pairs well with pork chops, cheesy biscuits, roasted mushrooms, or garlic bread chaffles for a satisfying dinner. It also fits vegetarian, gluten‑free, and keto menus when served alongside compatible mains.
Store
Let the cauliflower cool completely, then store in an airtight container in the refrigerator for 4–5 days. Freezing is possible but will change the texture noticeably.
Reheat
Reheat in the air fryer at 350°F for 2–4 minutes until warmed through and crisp. To reheat larger batches, use a 375°F oven for 4–6 minutes; it won’t be quite as crisp but works well for quantity.
