Ingredients

Meat and Vegetables

  • 2 tablespoons olive oil
  • 1 small yellow onion, chopped
  • pounds ground beef
  • 3 pounds Yukon gold potatoes, peeled and thinly sliced

Seasonings and Dairy

  • 1½ teaspoons sea salt
  • 1 teaspoon freshly ground black pepper
  • 2 cans (10.5 ounces each) condensed cream of mushroom soup
  • 1 cup milk
  • 1 cup sour cream
  • 2 teaspoons Italian seasoning
  • 2½ cups shredded Colby Jack cheese, divided
  • Chopped fresh parsley for garnish

Instructions

  1. Preheat Oven: Preheat your oven to 375°F to ensure it’s ready for baking the casserole evenly.
  2. Sauté Onion: Heat olive oil in a large skillet over medium heat. Add the chopped onion and cook until it becomes translucent, about 5 minutes, releasing its sweetness.
  3. Cook Ground Beef: Add ground beef to the skillet. Season with sea salt and black pepper. Cook, stirring occasionally, until the beef is browned and fully cooked through, about 6 to 8 minutes. Drain any excess fat and set the meat aside.
  4. Prepare Creamy Sauce: In a mixing bowl, combine the condensed cream of mushroom soup, milk, sour cream, and Italian seasoning. Stir thoroughly until smooth and well blended. Set aside.
  5. Prepare Baking Dish: Grease a 9×13-inch baking dish lightly. Spread a small amount of the creamy soup mixture evenly across the bottom of the dish to prevent sticking and add flavor.
  6. Layer Potatoes: Arrange one-third of the thinly sliced potatoes evenly over the bottom of the baking dish to form the first layer.
  7. Add Soup Mixture: Spread one-third of the creamy soup mixture over the potatoes to coat them evenly.
  8. Layer Beef and Cheese: Distribute half of the cooked ground beef evenly over the soup layer. Then sprinkle 1 cup of the shredded Colby Jack cheese on top.
  9. Repeat Layers: Add another third of the potato slices on top of the cheese, then spread one-third of the soup mixture over that layer. Follow with the remaining half of the ground beef and another 1 cup of the shredded cheese.
  10. Final Potato and Sauce Layer: For the last layer, place the final third of the potato slices evenly on top. Cover with the remaining soup mixture and sprinkle with the remaining ½ cup of shredded Colby Jack cheese.
  11. Cover and Bake: Cover the casserole with aluminum foil tightly to keep moisture in. Bake in the preheated oven for 45 minutes to cook the potatoes through.
  12. Brown the Cheese: Remove the foil and bake uncovered for an additional 15 minutes or until the cheese is bubbly and golden brown on top.
  13. Rest and Garnish: Let the casserole rest for 10 minutes after removing from the oven to set up for easier serving. Garnish with chopped fresh parsley before serving warm. Enjoy your comforting casserole!

Notes

  • For best results, slice the potatoes thinly and evenly to ensure uniform cooking.
  • If you prefer a thicker sauce, reduce the milk slightly or add more sour cream.
  • You can substitute Colby Jack cheese with cheddar or mozzarella based on your preference.
  • This casserole can be prepared a day ahead, assembled, covered, and refrigerated, then baked when ready.
  • Leftovers keep well covered in the refrigerator for up to 3 days and can be reheated in the oven.
