Preheat your air fryer to 380°F (193°C).
Place the cauliflower florets into a large mixing bowl.
Drizzle with olive oil and lemon juice.
Sprinkle smoked paprika, garlic powder, sea salt, and black pepper over the cauliflower.
Toss until every floret is evenly coated.
Arrange the Air Fryer Cauliflower in a single layer inside the air fryer basket. Cook in batches if necessary to avoid overcrowding.
Air fry for 7–10 minutes, shaking the basket halfway through cooking.
Cook until the florets are browned around the edges and tender inside.
Serve immediately with your favorite dipping sauce or alongside your main course.
