Step-by-Step Instructions
Step 1: Prep the Cauliflower
Steam or microwave the cauliflower until just tender. Drain very well, then finely chop.
Pro tip: Excess moisture is the #1 enemy of crispy results. Pat dry if needed.
Step 2: Mix the Gratin Base
In a bowl, combine cauliflower, cheese, cream, egg, and seasonings. Mix until evenly coated.
Pro tip: Let the mixture rest 2 minutes so flavors meld.
Step 3: Preheat & Prepare
Preheat your air fryer to 375°F (190°C). Lightly grease silicone muffin cups or a mini muffin pan.
Pro tip: Silicone molds release better and brown evenly.
Step 4: Fill the Cups
Spoon the mixture into molds, filling each almost to the top. Sprinkle extra cheese if desired.
Step 5: Air Fry
Cook for 12–15 minutes, until golden on top and set in the center.
