Description

A comforting and easy leftover spaghetti bake that transforms your favorite spaghetti with sauce into a delicious casserole layered with Italian seasoning, eggs, butter, parmesan, and melted cheddar cheese. Perfect for using up leftovers and serving a hearty meal for the whole family.


Ingredients

Main Ingredients

  • Your favorite spaghetti recipe with sauce (about 6 cups cooked spaghetti with sauce)
  • 1 Tbsp Italian seasoning
  • 2 eggs (beaten)
  • 2 Tbsp butter (melted)
  • 1/2 cup grated Parmesan cheese
  • 2 cups shredded cheddar cheese


Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 350 degrees F (175 degrees C). Grease a 9×13 inch baking dish well to prevent sticking and allow for easy serving.
  2. Mix Ingredients: In a large bowl, combine your leftover spaghetti with sauce, Italian seasoning, beaten eggs, melted butter, and grated Parmesan cheese. Mix thoroughly to ensure all ingredients are evenly incorporated.
  3. Bake Covered: Spread the spaghetti mixture evenly into the prepared baking dish. Cover the dish tightly with aluminum foil and bake in the preheated oven for 30 minutes, allowing the flavors to meld and eggs to set.
  4. Add Cheddar Cheese and Finish Baking: Carefully remove the foil and sprinkle the shredded cheddar cheese evenly over the top. Return the bake to the oven uncovered and cook for an additional 10 minutes, or until the cheese has melted and is slightly bubbly.

Notes

  • You can use any leftover spaghetti with your preferred sauce, such as marinara, meat sauce, or creamy sauce.
  • For a crispier top, broil for 1-2 minutes after the final baking step—watch carefully to prevent burning.
  • To add extra protein, consider mixing in cooked ground beef or Italian sausage with the spaghetti before baking.
  • This dish stores well in the refrigerator for up to 3 days and can be reheated in the oven or microwave.
  • Feel free to swap cheddar cheese for mozzarella or a combination for varied flavor and texture.
