Before You Begin
Prepare cookware as needed. Cooking times and results may vary depending on equipment and floret size.
Preheat oven to 425°F (218°C) or air fryer to 400°F (205°C). Line baking sheet if using oven.
In a bowl, whisk flour, onion powder, garlic powder, ginger, salt, and pepper.
Gradually whisk in non-dairy milk until a smooth batter forms that lightly coats the cauliflower.
Dip each floret into batter, allow excess to drip off, then coat evenly in panko. Press gently so crumbs adhere.
Arrange in a single layer with space between pieces.
Bake for 15 minutes, flip, then bake another 15 minutes until the coating is crisp and lightly golden.Air fry for 15–25 minutes, shaking halfway through, until the coating is crisp and the cauliflower is tender when pierced with a fork.
In a separate bowl, mix sweet chili sauce, vegan mayonnaise, sriracha, nutritional yeast (if using), and salt until smooth.
Transfer hot cauliflower to a bowl and gently toss with sauce just before serving.
Serve immediately for best texture.
