Not your momma’s spaghetti recipe. Once you make this elevated spaghetti, the plain old version will never be the same. A layer of spaghetti sauce, then a layer of spaghetti noodles, then a layer of a cream cheese mixture with chopped onions and green bell peppers, another layer of spaghetti sauce, a layer of Italian cheese and then topped with crispy fried onions.


  • 8 oz spaghetti noodles
  • 1 lb ground beef
  • 1 large jar of spaghetti sauce (26.5 oz-32 oz)
  • 18 oz block of cream cheese
  • 1 green bell pepper, chopped
  • 1 small yellow onion, diced

  • 23 cups crispy fried onions

  2. Cook spaghetti to al dente according to package directions. Drain and set aside.
  3. In a skillet brown ground beef until cooked through.

  6. Heat the mixture in the microwave for 5 minutes.
  7. Carefully remove from the microwave and remove the plastic wrap. Be careful, the steam will be extremely hot!
  8. Add the cream cheese to the hot mixture and stir until the cream cheese is completely melted and mixed in.
  9. Using a 9×13 pan, spread 1 cup of the spaghetti meat sauce onto the bottom of the pan.
  10. Next add your spaghetti noodles and spread them out evenly over top of the spaghetti sauce.
  11. Spread the cream cheese mixture evenly over top of the noodles.
  12. Use the rest of the spaghetti sauce and pour it evenly on top of the cream cheese mixture.
  13. Spread your Italian cheese evenly over top of the sauce.
  14. Cover with tinfoil and bake in the oven for 30 minutes.
  15. After 30 minutes, remove the tinfoil and spread the crispy fried onions evenly over the top.
  16. Return to the oven and bake for 5 minutes.
  17. Remove the casserole and let stand for 10 minutes before cutting.
