01 - Preheat oven to 375°F. Line a 9x5 inch loaf pan with parchment paper or lightly grease with cooking spray.
02 - In a large bowl, combine ground beef, ground pork, panko breadcrumbs, eggs, milk, green onions, carrot, garlic, ginger, 2 tablespoons gochujang, soy sauce, sesame oil, salt, and pepper. Mix gently with hands or a spatula until just combined. Do not overmix to maintain a tender texture.
03 - Transfer the mixture to the prepared loaf pan, pressing gently to form an even layer.
04 - In a small bowl, whisk together 3 tablespoons gochujang, ketchup, honey, 1 tablespoon soy sauce, rice vinegar, and 1 teaspoon sesame oil until smooth and well combined.
05 - Spread half the glaze evenly over the top of the meatloaf. Bake for 45 minutes.
06 - Remove from oven and spread the remaining glaze on top. Return to oven for another 10 minutes, or until internal temperature reaches 160°F.
07 - Let the meatloaf rest for 10 minutes before slicing and serving to allow juices to redistribute.
