Preparing Ultimate Loaded Potato Meatloaf is straightforward if you follow these easy steps:

1. Preheat your oven to 350°F (175°C). This ensures the meatloaf bakes evenly and reaches a delicious texture.
2. In a large mixing bowl, combine the ground meat, mashed potatoes, shredded cheese, and crumbled bacon. Mix well to incorporate all ingredients.
3. Add the chopped onion, garlic, breadcrumbs, egg, Worcestershire sauce, Dijon mustard, salt, and black pepper to the meat mixture. Mix thoroughly until well-combined.
4. Transfer the meat mixture into a greased loaf pan. Press it down lightly to remove any air pockets and shape it evenly.
5. Place the loaf pan in the preheated oven and bake for about 1 hour or until the internal temperature reaches 160°F (70°C). The meatloaf should be golden brown and cooked through.
6. Remove the meatloaf from the oven and let it rest for about 10 minutes before slicing. This allows the juices to redistribute, ensuring every bite is moist.
7. Top with sour cream and garnish with chopped green onions (if desired) before serving. This adds an extra layer of flavor and a beautiful presentation.
