Step One: Dice your cauliflower into florets. Toss the diced cauliflower, olive oil, black pepper, garlic powder, and salt in a large bowl.

Step Two: Toss to coat, pour the coated cauliflower into the air fryer, and set the temperature to 400 degrees F, air fryer setting, for 15 to 18 minutes. Shake the basket several times during the cooking process. Remove the roasted cauliflower from the air fryer.

Easy Air Fryer Roasted Cauliflower Mash Recipe Tips

  • Don’t Skimp on Roasting: The key to this recipe’s flavor is the caramelization achieved in the air fryer. The high heat develops a deep, nutty flavor that you won’t get from simply boiling. Make sure your florets have started to brown and sweeten before mashing.
  • Avoid Overcrowding: Cook the cauliflower in a single layer in the air fryer basket, if possible, or in batches. Overcrowding traps steam, preventing the florets from roasting properly and leading to a bland, mushy result.
  • Use Hot Liquids: When blending, use heavy cream and butter that are warm or melted. Adding cold dairy drastically cools the cooked cauliflower, making it harder to blend into a smooth, velvety consistency.
  • The Power of Gouda: While you can use cream cheese or Parmesan, Gouda adds an unparalleled savory, slightly smoky richness to the mash. Don’t skip it if you want that truly decadent flavor.
  • Drain Thoroughly: If you rinse your cauliflower before seasoning, make sure it is completely dry before adding the oil and spices. Any residual water will cause the cauliflower to steam instead of roast, compromising the texture.
