FAQ's

Why is leftover spaghetti so good?

Leftover spaghetti is great because the sauce and noodles have had time to meld together and become even more flavorful. It's also a great way to enjoy yesterday's dinner in a totally new way!

Top Tip

Because you are adding this dish back to the oven to bake, ensure you only cook your pasta to al dente.

Variations

  • Try adding additional vegetables such as mushrooms or bell peppers for added flavor. That's how I made it last time. It was SO GOOD!
  • You can add Italian sausage or ham to this dish if you'd prefer! Use your favorite marinara sauce to customize this casserole.

Storage

Refrigerate - Leftovers can be stored in an airtight container for up to 4 days.

Freezer - This casserole can be frozen for up to 3 months. Thaw overnight and heat in the oven or microwave before serving.

Reheat - My favorite way to reheat the casserole is the oven. Place in preheated 350 degree oven for about 20 minutes. Make sure to cover it with foil if the cheese is getting too brown.

You can also reheat individual servings in the microwave for 2-3 minutes. Be sure to cover it with a paper towel so it doesn't splatter.

      This is a very tasty dish but you're going to use almost every pot and pan in your kitchen. Lots of dishes to do after dinner.

      You forgot the garlic in ingredient list but mentioned it in instructions.

        My apologies Rosie, I did not use garlic in this recipe and have removed it from the instructions. Thanks for bringing it to my attention.
