Leftover Spaghetti Bake is an easy way to really transform leftover spaghetti into a different meal the second night. You can use spaghetti with meat sauce or with meatballs in this recipe too! The sky is the limit.

Leftover Spaghetti and Meatball Bake

This Baked Spaghetti recipe was born from the desire to have something besides leftover spaghetti the second night.

Spaghetti is a favorite around our house, and we eat it frequently.

But it makes a lot, and there’s always enough for another night’s dinner.

Sometimes I just want to do something different than warming up the leftover spaghetti in the microwave though.

So, this is how I throw the spaghetti together in a casserole dish to make it an entirely new meal.

This is a very popular recipe on our blog so I hope you enjoy it too!

Leftover Spaghetti and Meatball Bake

Key to Success #1 – Choose Your Own Adventure

This basic leftover spaghetti dish can be customized a zillion different ways but it all starts with your favorite spaghetti recipe.

My son, Noah, loves spaghetti and meatballs. He insists on the meatballs.

So my leftover spaghetti almost always has meatballs in it.

First, combine your spaghetti noodles and your sauce if not already done so.

You can add additional meat or additional vegetables to your spaghetti if you’d like.

You can add onions or peppers or carrots if you’d like but make sure they’re already cooked/soft before you add them since this is a quick-cooking pasta dish.

The amount of pasta you have is not super important either.

If you have at least 3-4 servings of pasta, I wouldn’t change the amount of the other ingredients listed in the recipe.

Key to Success 2 – Bake Covered

After you add the Italian seasoning, eggs, butter, and Parmesan cheese, spread the pasta into your greased baking dish and cover the whole thing with aluminum foil. (Does anyone still call it tin foil?)

You’ll bake the pasta for about 30 minutes covered with foil.

Make sure the foil is fully covering the pasta so that it doesn’t dry out in the oven.

If you reach 30 minutes and you feel like your pasta is not warm enough, pop it back into the oven covered for up to 15 minutes more.

Key to Success #3 – Sprinkle on the Cheese

I like to top this Spaghetti Bake with freshly shredded cheddar cheese but you could also use mozzarella cheese for a more traditional Italian spaghetti dish.

However, I’m a big lover of cheddar cheese on spaghetti, so I hope you’ll give it a shot.

After you’ve sprinkled the cheese on top of the oven-warmed spaghetti bake, return it to the oven for another 10 minutes or so, uncovered, until the cheese is melted and gooey.

You may also use a broiler to melt the cheese on top of this dish if you have one.

Just keep an eye on it to make sure it doesn’t become too brown!

I would be remiss if I didn’t mention that you can make this dish with fresh pasta as well.

I’d suggest using a half-pound of cooked pasta noodles (does not have to be spaghetti!) and a jar of prepared sauce.

I prefer the Prego Traditional pasta sauce but you can use your favorite variety or even homemade spaghetti sauce.

If I have leftovers how might I go about reheating this?

Jennifer

With pretty much any casserole, I slice a square of the casserole and remove it to a microwave-safe plate using a spatula. Then I cut the square of casserole in quarters and spread them apart from each other a smidge then microwave on high power until they are heated through. Having smaller pieces helps the meal reheat more evenly and also faster.

Hi, should I warm the left over spaghetti a little first?

Jennifer

It would definitely speed up the process to warm it up a bit. Not required though!

@Jennifer, I take it back! I tried just now to get the recipe on my iphone as I make it, and I'm back on my computer because there are too many ads covering the ingredients and recipe.

@Jennifer, I can't see it on safari on a mac, but I can on Chrome and on my phone. I will say - I know you deserve to be compensated for all your hard work, but YIKES this is a LOT of ads... Even on chrome, it's pretty cluttered and slow and the page skips up and down all the time. Not the best user experience... But, I am making this tonight and I know it'll be delish!

I have not tried this yet. Just wondering what the egg does for the recipe??

Jennifer

The egg works to bind the ingredients together more like a traditional casserole. If you’d like, you can leave it out.

How much spaghetti do you need for this dish?

This recipe is very forgiving as far as the amount of spaghetti goes. I would say as long as you have enough for 3-6 servings of spaghetti, then you are good to go. Hope this helps!
