Ingredients

  • 6-7 large potatoes
  • 1 tablespoon butter
  • 3/4 cup milk
  • 2 tablespoons canola oil
  • 1/2 medium red onion , chopped
  • 1/2 medium green bell pepper , chopped
  • 1 large garlic clove , minced
  • 1 teaspoon dried oregano
  • 2 teaspoons salt , divided
  • 1/2 teaspoon ground black pepper
  • 1 pound ground beef
  • 1/2 cup tomato sauce
  • 1 cup of water
  • 1/2 cup shredded mozzarella cheese
  • 1 cup shredded mild cheddar cheese

Instructions

  • Preheat oven to 350 degrees.
  • In a medium pot, boil the potatoes with 1 teaspoon of salt, until tender. Remove potatoes from the pot and using a potato masher, mash the potatoes until they are made pure. Add the butter and milk, and combine well. Set aside.
  • Season the meat with the onion, pepper, garlic, oregano, salt and pepper.
  • In a medium pan, heat the oil over medium-hot heat. Add the meat and let cook until brown. Add the tomato sauce and water. Let simmer until all the liquid had evaporated.

To Assemble

  • Lightly spray a glass baking pan with cooking spray. Add a layer of mash potatoes to the bottom of the pan. Then, add a second layer with all the cooked ground beef. Sprinkle half of the mozzarella and mild cheddar cheese. Spread another layer of mash potatoes and top with the rest of the cheese.
  • Place in the oven, uncovered, for about 15-20 minutes or until the cheese has completely melted.
  • Serve warm.

Notes

  • This casserole can be made ahead and placed in the fridge after been assembled. When ready to eat, simply place in the oven covered for 30 minutes and then uncovered for an additional 15 minutes.
  • I love this casserole with ground beef, but you can also make it with ground lamb, chicken or turkey.
  • Feel free to add in other veggies like carrots or mushrooms if you like.
