Prep the veggies: Finely grate or pulse your chosen vegetables. Squeeze out extra water from high-moisture veggies like zucchini with a clean towel so the mixture isn’t too wet.
Mix the base: In a bowl, add ground chicken, the prepared veggies (1 cup), egg, yogurt or applesauce, 1/2 cup breadcrumbs, seasonings, and optional Parmesan/parsley. Stir until just combined.
The mixture should be soft but scoopable.
Adjust texture: If it’s very sticky, add 1–2 tablespoons more breadcrumbs. If it seems dry, mix in 1 tablespoon more yogurt or applesauce.
Set up coating: Pour remaining breadcrumbs into a shallow dish. Lightly oil a baking sheet or preheat the air fryer to 375°F (190°C).
Shape the nuggets: Scoop tablespoon-sized portions.
Gently pat into nugget shapes (about 1/2 inch thick). Press each side into the breadcrumbs to coat. For toddlers, smaller, flatter shapes cook evenly and stay tender.
Bake option: Arrange on the oiled sheet, mist the tops with oil spray, and bake at 400°F (205°C) for 12–15 minutes, flipping halfway, until the centers reach 165°F (74°C) and the outsides are lightly golden.
Air-fry option: Air fry at 375°F (190°C) for 8–10 minutes, flipping once, until cooked through and golden.
Avoid crowding the basket.
Cool and serve: Let nuggets rest for 3–4 minutes to set. Serve warm with a simple dip and soft veggies or fruit on the side.
