Combine the milk and the stuffing in a medium bowl. Set aside for 5 minutes to soak.
Combine the ground meats, eggs, parmesan, salt and pepper, and the stuffing milk mixture in a large bowl. Gently mix with your hands until combined. DO NOT overmix. This will make the meatloaf dry and tough.
On a baking sheet lined with parchment paper, form the meatloaf in to a log shape. It should be about 4-5" high.
Bake for 60 minutes, or until it reaches an internal temperature of 160°F.
Serve with garlic butter sauce and enjoy!
For the Garlic Butter Sauce
Melt the butter in a small saucepan over medium heat. Add the garlic and cook until it's fragrant and softenend (2-3 minutes).
Add the chicken stock and the thyme. Reduce for 10-15 minutes or so.
Take off the heat and serve over meatloaf.
Don't overmix your meatloaf! This will make it tough and dry. Use whatever flavor of stuffing you like! I loved the chicken, but feel free to try pork, turkey, cornbread, or herb.
