Prep the air fryer: Preheat to 390°F (200°C) for 3–5 minutes. Line the basket with a perforated parchment liner if you have one, or lightly oil the basket to prevent sticking.
Mix the chicken base: In a bowl, combine ground chicken, egg, Parmesan, salt, pepper, garlic powder, onion powder, paprika, and optional hot sauce. Stir until evenly mixed.
The mixture should be tacky but not wet.
Set up breading station: Place flour in one shallow bowl, panko in another. If you like, season the panko with a pinch of salt and paprika for extra flavor.
Shape the hearts: Scoop about 1 1/2 tablespoons of the chicken mixture. With slightly damp hands, press into a small heart shape about 1/2 inch thick.
Keep sizes uniform so they cook evenly.
Bread the nuggets: Lightly coat each heart in flour, tap off excess, then press into panko on both sides. Gently reshape the heart if needed.
Load the basket: Arrange nuggets in a single layer with a little space between them. Lightly spray the tops with oil. Do not overcrowd; cook in batches for best results.
Air fry: Cook at 390°F (200°C) for 8–10 minutes, flipping halfway and spraying again after flipping.
They’re done when the coating is golden and the internal temp hits 165°F (74°C).
Rest briefly: Let nuggets rest on a wire rack for 2–3 minutes to set the crust.
Serve: Plate with your favorite dips. For a fun touch, add carrot coins or strawberry slices to keep the “heart” theme going.
