Preheat the oven to 425°F (220°C). Line a large baking sheet with foil or spray it with non-stick cooking spray and set aside.
Place the cornflakes, Italian seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper in a food processor and pulse until coarse crumbs remain; alternatively, put the cornflakes in a resealable plastic bag and crush with a rolling pin. Transfer to a shallow dish.
In a separate shallow dish, whisk together the eggs and half-and-half (or milk) until smooth.
Dip each chicken strip first into the egg mixture, letting excess drip off, then press into the cornflake mixture to coat thoroughly. Place coated strips on the prepared baking sheet in a single layer.
Bake for 15–20 minutes, or until the chicken registers 165°F (74°C) in the thickest part and the coating is golden and crisp.
Remove from the oven, sprinkle with chopped parsley, and serve immediately with your preferred dipping sauce.
