Preheat oven to 350°F. Line an 8x4-inch loaf pan with parchment paper if you do not want to slice the meatloaf in the pan.
In a large bowl, stir together the whisked egg, breadcrumbs, seasoning mix, Worcestershire sauce, and milk and let sit for 2-3 minutes.
Add the ground beef to the breadcrumb mixture, and use your hands to mix together to fully combine. Do not overmix the meat or the meatloaf will be tough.
Add the meat mixture to a loaf pan. Pat the meat down into an even layer.
In a small bowl, stir together the glaze ingredients. Pour the glaze on top of the meatloaf and spread it into an even layer.
Bake on the middle rack for 1 hour and 15 minutes for an 8x4, or until the internal temperature reaches 160°.
Let the meatloaf rest for 10 minutes before cutting and serving.
