Boil the potatoes: Place the peeled and quartered potatoes in medium sized pot. Cover with at least an inch of cold water. Add a teaspoon of salt. Bring to a boil, reduce to a simmer, and cook until tender (about 20 minutes.

2 Sauté vegetables: While the potatoes are cooking, melt 4 tablespoons of the butter in a large sauté pan on medium heat. Add the chopped onions and cook until tender, about 6 to 10 minutes.

Add the ground beef, then Worcestershire sauce and broth: Add ground beef to the pan with the onions and vegetables. Cook until no longer pink. Season with salt and pepper.

Mash the cooked potatoes: When the potatoes are done cooking (a fork can easily pierce), remove them from the pot and place them in a bowl with the remaining 4 Tbsp of butter. Mash with a fork or potato masher, and season with salt and pepper to taste.

5 Layer the meat mixture and mashed potatoes in a casserole dish: Preheat oven to 400°F. Spread the beef, onions, and vegetables in an even layer in a large baking dish

Bake in oven: Place in a 400°F oven and cook until browned and bubbling, about 30 minutes. If necessary, broil for the last few minutes to help the surface of the mashed potatoes brown
