Creating Meatloaf and Mashed Potatoes with Gravy can be straightforward by following these step-by-step instructions:

For the Meatloaf:

1. Preheat your oven to 350°F (175°C).
2. In a large mixing bowl, combine ground beef, breadcrumbs, milk, ketchup, chopped onion, eggs, Worcestershire sauce, garlic powder, Italian seasoning, salt, and pepper.
3. Mix until just combined; avoid over-mixing, as this can make the meatloaf tough.
4. Shape the mixture into a loaf and place it in a greased baking dish.
5. Bake in the preheated oven for 1 hour or until the internal temperature reaches 160°F (70°C).
6. Once cooked, let the meatloaf rest for 10 minutes before slicing.

For the Mashed Potatoes:

1. While the meatloaf is baking, place the peeled and diced potatoes in a large pot and cover with cold water.
2. Add salt to the water and bring to a boil over medium-high heat.
3. Cook the potatoes until tender, about 15-20 minutes, then drain.
4. In the same pot, add butter and heavy cream to the drained potatoes.
5. Mash the potatoes until creamy and smooth; season with salt and pepper to taste.

For the Gravy:

1. After removing the meatloaf from its baking dish, pour the drippings into a medium saucepan over medium heat.
2. Whisk in the flour, stirring constantly for 1-2 minutes until it turns light brown.
3. Gradually add beef broth, whisking vigorously to prevent lumps.
4. Continue to cook until the gravy thickens; season with salt and pepper to taste.
