FAQs
Can I make this ahead of time?
While best served fresh, you can prep the florets up to 24 hours in advance.
Why isn’t my cauliflower getting crispy?
Excess moisture and overcrowding are usually the culprits. Ensure florets are dry and well-spaced.
Can I use frozen cauliflower?
Fresh is best for crispiness, but frozen will work if thoroughly thawed and dried.
What’s the best way to reheat leftovers?
Use an air fryer at 375°F for 3-4 minutes or reheat in a hot oven until crispy.
