Ingredients

  • ½ pound spaghetti boiled and drained
  • ¾ pound sliced beef liver
  • 2 tbsp butter
  • 2 tbsp flour
  • 1 cup canned tomatoes or your favorite pasta sauce
  • 1 small onion minced
  • 1 tsp salt
  • 1 tsp sugar
  • Few grains black pepper
  • Mozzarella cheese shredded (to taste)

Instructions

  • Prepare the Liver
    Scald liver in hot water for a few seconds. Drain and remove any skin or veins. Slice into small, bite-sized pieces.
  • Sauté the Liver
    Melt butter in a frying pan over medium heat. Lightly dust liver with flour and sauté in the butter until browned.
  • Assemble the Casserole
    In a greased baking dish, layer the cooked spaghetti and sautéed liver in alternating layers.
  • Make the Sauce
    In a bowl, combine canned tomatoes (or pasta sauce), minced onion, salt, sugar, and pepper. Stir well and pour evenly over the liver and spaghetti layers.
  • Bake
    Cover the dish with foil or a lid and bake in a moderate oven (350°F / 175°C) for about 1 hour.
    Remove the cover during the last 15 minutes to allow the top to brown slightly.
    Sprinkle with shredded mozzarella cheese just before uncovering if desired.

Notes

  • Scalding the liver makes it easier to peel and improves texture.
  • You can substitute chicken livers or use a mix of beef and pork liver if preferred.
  • Add chopped bell peppers or mushrooms to the sauce for added flavor.
  • Try Parmesan cheese instead of mozzarella for a sharper flavor profile.
  • Storage: Refrigerate leftovers in an airtight container for up to 3 days.
