Ingredients
  

  • 1 pound ground beef
  • 1 medium onion, chopped

  • 2 cloves garlic, minced
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 6 medium potatoes, peeled and thinly sliced
  • 1/2 cup milk
  • 1/4 cup butter, melted
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 cups shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese

Equipment

  • 9x13-inch baking dish
  • large skillet
  • Large bowl
  • Mixing spoon
  • Measuring cups
  • Measuring spoons
  • Potato peeler
  • knife
  • cutting board
  • aluminum foil
  • Oven

Method
 

  1. Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish.
  2. Chop the onion and bell pepper, mince the garlic, and peel and thinly slice the potatoes.
  3. In a large skillet, brown the ground beef over medium heat. Drain off any excess grease.
  4. Add the chopped onion and bell pepper to the skillet and cook until softened, about 5 minutes.
  5. Stir in the minced garlic, tomato sauce, oregano, basil, salt, and pepper. Bring to a simmer and cook for 10 minutes, stirring occasionally.
  6. In a large bowl, combine the thinly sliced potatoes, milk, melted butter, salt, and pepper. Mix well to coat the potatoes evenly.
  7. Spread the ground beef mixture evenly in the prepared baking dish.
  8. Arrange the potato slices over the ground beef mixture in an even layer, slightly overlapping if necessary.
  9. Cover the baking dish with aluminum foil.
  10. Bake for 45 minutes.
  11. Remove the foil and sprinkle the shredded cheddar and Monterey Jack cheese evenly over the potato layer.
  12. Bake for an additional 15-20 minutes, or until the cheese is melted and bubbly and the potatoes are tender when pierced with a fork.
  13. Let the casserole rest for 10 minutes before serving.

Notes

For evenly cooked potatoes, slice them about 1/8 inch thick. Experiment with different cheeses like pepper jack or smoked Gouda. For a spicier flavor, add a pinch of red pepper flakes to the ground beef mixture. This casserole can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. Leftovers can be frozen for up to 2 months.
