Patty'S String Pie

Directions

1. 1
   Preheat oven to 350 degrees F (175 degrees C).
2. 2
   Brown ground beef in a large skillet over medium heat until crumbly and no longer pink, about 10 minutes. Drain and set aside in a bowl. Cook and stir onion and green bell pepper in the same skillet until onion is translucent, about 5 minutes. Stir onion, green pepper, and spaghetti sauce into ground beef.
3. 3
   Bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water, stirring occasionally until cooked through but firm to the bite, about 10 minutes. Drain and transfer to a bowl. Let pasta cool slightly and stir beaten eggs and Parmesan cheese into spaghetti.
4. 4
   Spread spaghetti mixture into a 9x13-inch baking dish. Spread ricotta cheese over pasta mixture in an even layer; top with ground beef mixture. Sprinkle mozzarella cheese evenly over the top of the casserole.
5. 5
   Bake in the preheated oven until the casserole is set in the center and the cheese topping is melted and lightly browned, about 35 minutes.
