Equipment

  • 9x13 inch Baking Dish
  • Large Pot
  • Large Skillet
  • Potato masher

Ingredients

Mashed Potato Layer

  • 3 pounds russet potatoes peeled and cubed
  • 1/2 cup unsalted butter softened
  • 1/2 cup sour cream
  • 1/2 cup whole milk warmed
  • 1 tsp garlic powder
  • salt and freshly ground black pepper to taste

Beef Layer

  • 1 1/2 pounds ground beef 85/15 fat content recommended
  • 1 medium yellow onion finely diced
  • 2 cloves garlic minced
  • 1 tbsp Worcestershire sauce
  • 2 tsp chili powder
  • 1 tsp smoked paprika
  • 1 tsp dried oregano
  • 1/2 tsp cumin

Topping

  • 2 cups sharp cheddar cheese freshly shredded
  • 8 strips bacon cooked crispy and crumbled
  • 3 green onions thinly sliced
  • 1/4 cup fresh parsley chopped

Instructions

  • Place the peeled and cubed potatoes in a large pot and cover with cold water. Add 1 tablespoon of salt to the water. Bring to a boil over high heat, then reduce to medium and simmer until fork-tender, about 15-20 minutes.
  • While the potatoes are cooking, brown the ground beef in a large skillet over medium-high heat, breaking it into crumbles. When the beef is about halfway cooked (after about 4 minutes), add the diced onions and continue cooking until the beef is no longer pink and the onions are translucent.
  • Drain excess fat from the beef, leaving about 1 tablespoon for flavor. Add the minced garlic and cook for 30 seconds until fragrant.
  • Stir in the Worcestershire sauce, chili powder, smoked paprika, dried oregano, and cumin. Season with salt and pepper to taste. Cook for an additional 2 minutes to allow the flavors to meld, then remove from heat.
  • Drain the cooked potatoes thoroughly and return them to the hot pot. Allow them to steam dry for 1-2 minutes. Add the softened butter and mash until mostly smooth.
  • Stir in the sour cream, warmed milk, garlic powder, salt, and pepper into the mashed potatoes. Avoid overmixing to prevent a gluey consistency.
  • Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. Spread the seasoned beef mixture evenly across the bottom of the dish.
  • Carefully spread the mashed potato mixture over the beef layer, creating an even top with some texture. Sprinkle the shredded cheddar cheese over the potatoes.
  • Bake uncovered for 25-30 minutes or until the cheese is fully melted and beginning to brown at the edges. The internal temperature should reach 165°F (74°C).
  • Remove from the oven and sprinkle with the crumbled bacon, sliced green onions, and chopped parsley. Let stand for 5 minutes before serving.

Notes

For a lighter version, substitute cauliflower for half the potatoes, use lean ground turkey instead of beef, and opt for reduced-fat dairy products.
Make ahead option: Assemble the casserole up to 24 hours in advance, cover and refrigerate. Add 10-15 minutes to the baking time if cooking directly from refrigerator.
Leftovers can be refrigerated for up to 3 days or frozen in individual portions for up to 2 months.
