Equipment

  • casserole dish

Ingredients

  • 1 lb lean ground beef
  • 1 cup chopped fresh mushrooms such as cremini or white button
  • 1/2 tsp garlic powder
  • 1/2 tsp kosher salt
  • 1/4 tsp black pepper
  • 1 can 10.5 oz cream of mushroom soup
  • 1/2 cup sour cream
  • 1 tsp Dijon mustard
  • 3 cups shredded sharp cheddar cheese divided
  • 6 medium Yukon gold potatoes peeled and thinly sliced (about 1/8-inch)
  • 1 tbsp butter for greasing the dish
  • Chopped parsley or chives for garnish (optional)

Instructions

  • Preheat oven to 375°F. Lightly butter a 9x13-inch baking dish.
  • In a large skillet over medium heat, cook the ground beef and mushrooms until the meat is browned and the mushrooms are soft, about 6–7 minutes. Stir in garlic powder, salt, and pepper. Drain any excess grease.
  • Remove from heat and stir in cream of mushroom soup, sour cream, Dijon mustard, and 1 cup cheddar cheese until smooth.
  • Reserve about 10 of the nicest-looking potato slices for the top. Layer half of the remaining potatoes in the prepared dish, then top with half of the beef mixture and 1 cup of cheese. Repeat layers of potatoes and meat once more.
  • Arrange reserved potato slices on top in a neat layer. Sprinkle remaining 1 cup cheddar cheese evenly over the top.
  • Cover tightly with foil and bake for 45 minutes. Remove foil and bake another 20–25 minutes, or until potatoes are fork-tender and the top is golden and bubbly.
  • Let rest 10 minutes before serving. Garnish with parsley or chives if desired.

Notes

  • Use a mandoline for quick, even potato slices. Be very careful!

  • Yukon gold potatoes hold their shape well and become tender without getting mushy.

  • Don’t skip the resting time. It helps the casserole set and makes slicing easier.

  • Add a sprinkle of crispy fried onions or crumbled bacon on top for a twist.

  • This dish is make-ahead friendly: assemble in the morning and bake before dinner.
  • Store leftovers tightly covered in the fridge for up to 4 days.
