Preheat the oven to 425°F (220°C). Line a large baking sheet with aluminum foil or spray it with non-stick cooking spray and set aside.
Place the cornflakes, Italian seasoning, garlic powder, onion powder, smoked paprika, sea salt, and black pepper in a food processor and pulse until the cornflakes are coarsely crushed but still have visible flakes; alternatively place them in a large zip-top 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 whole milk) until combined.
One at a time, dip each chicken strip into the egg mixture, letting excess drip off, then press into the crushed cornflake mixture to fully coat. Place coated pieces on the prepared baking sheet in a single layer.
Bake for 15 to 20 minutes, until the coating is golden and an instant-read thermometer inserted into the thickest part of the chicken reads 165°F (74°C).
Remove from the oven, sprinkle with chopped parsley, and serve immediately with your favorite dipping sauce if desired.
