Ingredients
  

  • 6 medium russet potatoes peeled and thinly sliced
  • 2 tablespoons butter
  • 1 medium yellow onion diced
  • 2 cloves garlic minced
  • 1 pound lean ground beef
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 1 teaspoon paprika
  • 1 teaspoon dried oregano
  • 2 tablespoons all-purpose flour
  • 1 cup low-sodium beef broth
  • ½ cup whole milk
  • 1 can 10.5 ounces cream of mushroom soup
  • 2 cups shredded Colby Jack cheese
  • 2 tablespoons chopped fresh parsley optional

Equipment

  • 9×13-inch baking dish
  • Large skillet
  • Sharp knife
  • Cutting board
  • Measuring cups and spoons
  • Wooden spoon
  • Aluminum foil

Method
 

  1. Heat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
  2. Peel and slice potatoes into even ¼-inch slices.
  3. Melt butter in a large skillet over medium heat. Cook onion until soft, then add garlic.
  4. Add ground beef and cook until browned. Season with salt, pepper, paprika, and oregano. Drain excess grease.
  5. Sprinkle flour over the beef. Stir and cook for 1 minute.
  6. Gradually stir in beef broth, milk, and cream of mushroom soup. Cook until the sauce becomes lightly thickened.
  7. Layer half the potatoes in the baking dish, followed by half the beef mixture. Repeat.
  8. Cover tightly with foil and bake for about 45 minutes, or until the potatoes are tender.
  9. Remove foil and sprinkle cheese over the top.
  10. Bake uncovered for 8–10 minutes, until the cheese melts and bubbles.
  11. Rest for 10 minutes. Garnish with parsley and serve.

Notes

  • Make ahead: Assemble up to 1 day ahead, cover, refrigerate, and bake when ready.
  • Potato tip: Keep the slices close to ¼ inch so they finish cooking together.
  • Cheese swap: Cheddar, Monterey Jack, or mozzarella can replace Colby Jack in the same quantity.
  • Storage: Refrigerate leftovers for 3–4 days or freeze for up to 3 months.
