How to Make White Bean And Spaghetti Squares

  1. Preheat oven to 375°F (190°C). Lightly grease a 3-quart shallow baking dish with nonstick olive oil spray.
  2. If the spaghetti is cold, reheat it in the microwave until warm. Place the spaghetti in the prepared baking dish.
  3. In a medium bowl, whisk together the milk, egg, and Romano cheese until well combined.
  4. Pour the egg mixture over the spaghetti, stirring gently to coat. Press the spaghetti mixture into the bottom and about 1 inch up the sides of the baking dish to form a crust.
  5. In a large skillet, heat the olive oil over medium heat. Add the chopped onion and bell pepper and cook for 4-5 minutes, or until softened.
  6. Stir in the minced garlic, oregano, and basil. Cook for 1 minute more, until fragrant.
  7. Add the rinsed and drained cannellini beans to the skillet. Stir to combine with the vegetables.
  8. Pour the cannellini bean mixture into the spaghetti crust.
  9. Spread the undrained diced tomatoes evenly over the bean filling.
  10. Sprinkle the mozzarella cheese over the tomatoes.
  11. Cover the baking dish with foil.
  12. Bake for 15 minutes.
  13. Remove the foil and bake for another 20-25 minutes, or until the filling is bubbly and the cheese is melted and golden brown.
  14. Let the casserole stand for 10 minutes before cutting into squares and serving.
