Preheat the oven to 375°F (190°C). Lightly grease a loaf pan or line a baking sheet with parchment paper.
In a large mixing bowl, combine the ground chicken, breadcrumbs, eggs, onion, garlic, milk, ketchup, Worcestershire sauce, Italian seasoning, garlic powder, onion powder, paprika, salt, and black pepper.
Mix until just combined, being careful not to overmix.
Shape the mixture into a loaf and place it in the prepared loaf pan or on the baking sheet.
In a small bowl, stir together the ketchup, brown sugar, and Dijon mustard.
Spread the glaze evenly over the top of the meatloaf.
Bake for 45 minutes, or until the internal temperature reaches 165°F (74°C).
Remove the meatloaf from the oven and let it rest for 10 minutes before slicing and serving.
