Making Meatloaf with Mashed Potatoes and Cheese is straightforward. Follow these simple yet effective steps:

1. Preheat the Oven: Preheat your oven to 350°F (180°C).
2. Prepare the Meatloaf Mixture: In a large bowl, combine ground beef (or turkey), breadcrumbs, egg, chopped onion, minced garlic, Worcestershire sauce, oregano, salt, and pepper. Mix until fully combined.
3. Shape the Meatloaf: Form the meat mixture into a loaf shape and place it on a baking sheet lined with parchment paper.
4. Add Ketchup: Spread ketchup evenly over the top of the meatloaf for added flavor and moisture.
5. Bake: Bake in the preheated oven for 45-50 minutes or until the internal temperature reaches 160°F (70°C).
6. Meanwhile, Cook the Potatoes: While the meatloaf is baking, place the cubed potatoes in a pot of salted water. Bring to a boil and cook until tender, about 15-20 minutes.
7. Mash the Potatoes: Once the potatoes are tender, drain and return them to the pot. Add milk, butter, and shredded cheddar cheese. Mash until smooth and creamy. Season with salt and pepper to taste.
8. Let the Meatloaf Rest: After baking, remove the meatloaf from the oven and let it rest for about 10 minutes to retain moisture.
9. Slice the Meatloaf: Carefully slice the meatloaf into portions.
10. Serve: Plate portions of meatloaf alongside generous servings of creamy mashed potatoes with cheese.
