Prep the cauliflower: Remove leaves and core. Break into florets.
Wash and dry well. Moisture is the enemy of crisp, so pat it very dry.
Rice it: Pulse florets in a food processor until they look like rice grains. Work in batches to avoid mush.
If using a box grater, grate on the medium holes.
Preheat the air fryer: Set to 375°F (190°C) for 3 minutes. A hot basket helps prevent sticking.
Season: In a large bowl, toss the riced cauliflower with oil, garlic, salt, and pepper. Add any optional spices.
You want a light, even coat—not greasy.
Load the basket: Spread the cauliflower rice in an even layer. Do not pack it tightly. If your air fryer is small, cook in two batches.
Air fry: Cook at 375°F (190°C) for 8–12 minutes total. Pull the basket out halfway and stir to promote even cooking.
Start checking at 8 minutes.
Finish: It’s done when the “grains” are tender with a few toasty bits. Taste and adjust seasoning. Add lemon juice or herbs if using.
Serve: Enjoy as a side, or use as a base for bowls, stir-fries, or burrito bowls.
