Creating Cheesy Meatloaf with Mashed Potatoes can be straightforward if you follow these simple steps:

For the Meatloaf

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Meat Mixture: In a large mixing bowl, combine the ground beef, shredded cheddar cheese, chopped onion, breadcrumbs, egg, milk, ketchup, Worcestershire sauce, garlic powder, salt, and pepper. Mix until just combined.
3. Shape the Meatloaf: Transfer the meat mixture to a loaf pan or shape it into a loaf on a baking sheet lined with parchment paper.
4. Bake: Place the meatloaf in the preheated oven and bake for 50-60 minutes, or until the internal temperature reaches 160°F (70°C).
5. Rest the Meatloaf: Once cooked, remove the meatloaf from the oven and let it rest for 10-15 minutes before slicing.

For the Mashed Potatoes

1. Boil the Potatoes: In a large pot, add the peeled and cubed potatoes. Cover with cold water and bring to a boil. Add a pinch of salt and cook until the potatoes are tender, about 15-20 minutes.
2. Drain and Mash: Once cooked, drain the potatoes and return them to the pot. Add the milk and butter, then mash until smooth and creamy. Season with salt and pepper to taste.
3. Adjust Consistency: If the mashed potatoes are too thick, add more milk until you reach your desired consistency.
