Ingredients
  

For the Potato Topping
  • 2 lbs Russet potatoes peeled and cut into 1-inch cubes
  • 1/4 cup butter
  • 1/2 cup milk warmed
  • 1/4 cup sour cream
  • 1 teaspoon salt or to taste
  • 1/2 teaspoon black pepper or to taste
  • 1 cup shredded sharp cheddar cheese divided
For the Beef Filling
  • 1.5 lbs lean ground beef 90/10
  • 1 medium onion diced
  • 2 cloves garlic minced
  • 1 tablespoon Worcestershire sauce
  • 1 can cream of mushroom soup 10.5 oz
  • 1 cup frozen mixed vegetables thawed

Equipment

  • 1 9x13 inch Baking Dish
  • 1 Large Skillet
  • 1 Large Pot

Instructions
 

  1. Place peeled and cubed potatoes in a large pot of salted water. Bring to a boil and cook for 15-20 minutes until fork-tender. Drain well.
  2. Return potatoes to the pot. Add butter, warmed milk, and sour cream. Mash until smooth. Season with salt and pepper, then stir in 1/2 cup of shredded cheddar cheese. Set aside.
  3. While potatoes boil, brown the ground beef and diced onion in a large skillet over medium-high heat. Drain excess grease.
  4. Stir in minced garlic and cook for 1 minute. Add Worcestershire sauce, cream of mushroom soup, and mixed vegetables. Simmer for 5 minutes.
  5. Preheat oven to 375°F (190°C). Spread the beef mixture in a 9x13 inch baking dish. Top evenly with the mashed potato mixture. Sprinkle the remaining 1/2 cup of cheese over the top.
  6. Bake for 25-30 minutes, until bubbly and the top is golden brown. Let rest for 5-10 minutes before serving.

Notes

For a richer flavor, feel free to add a splash of red wine to the beef mixture while it simmers.
Ensure potatoes are well-drained to prevent a watery topping.
