Preheat your air fryer to 400°F (200°C).
In a large bowl, toss steak cubes and gnocchi with olive oil, salt, pepper, garlic powder, and smoked paprika.
Place the mixture in a single layer in the air fryer basket. Cook in batches if necessary.
Air fry for 10-12 minutes, shaking halfway through, until steak is browned and gnocchi is golden and crispy.
Serve warm, garnished with parsley and parmesan if desired.
