Leftover Spaghetti Casserole
LEFTOVER spaghetti casserole recipe! Don’t panic, I got a easy casserole recipe for you that’s delicious! You’re going to love this cheesy spaghetti casserole!
Do you like leftovers? I am pretty picky about them.
Last week I made my favorite Crockpot Tacos and we had them 4 days in a row, and every single night I looked forward to them. That’s one leftover I love! Then there are those leftovers where you just don’t know what to do with. Usually I can talk Matthew into eating them for lunch, but sometimes there’s even still a few meals left over (I tend to cook for a army).
Leftover Spaghetti
When I make spaghetti, there’s usually always leftover noodles. I’d rather not have spaghetti two nights in a row, so I wanted to find something a little more exciting to do with the leftover spaghetti so I came up with this casserole.
How good was it? Matthew asked if we could have it again, which made me feel pretty happy in having a meal requested from leftovers!
So next time you have leftover spaghetti, don’t you dare toss it.. make this Leftover Spaghetti Casserole!
Do you eat leftovers? Are there any leftovers you won’t eat? Do you also cook for a army?

I love leftovers! This is a delicious use of leftover chicken and pasta. The casserole looks comforting and delicious. A perfect weekday meal.
There are some leftovers that I look forward to every night too. This spaghetti would be one of them — anything with melted cheese all over the top is something I’d enjoy night after night!
Repurposing leftovers is my favorite way to make an old meal taste new! Love the sounds of this casserole!
Great way to use the leftovers, I am usually good for 1 day of leftovers then it just gets too old but this breathes new life into the leftover spaghetti. I too tend to cook for an army and its just me and the pugs, I need to learn how to downsize my meals.
I have learned to make extra these days so that I will have leftovers. This is a great idea – quick & easy, which is the best!
I used to think you were the muffin queen – now you can add leftovers queen to your expanding array of accomplishments!
I love leftovers (leftovers =No cooking on busy nights=score!!!)
Spaghetti in casserole form is a BRILLIANT concept, Pamela – simply BRILLIANT!
In Italy we sometimes use leftover spaghetti to make a spaghetti frittata. Baking pasta is also another great option. Yum… pasta is too good to be tossed!
I’d go for that! 🙂 ela
…nice to see all the happy kitties on top…
Great use of those leftovers!
I’m a big leftovers gal, in fact, sometimes I make more than I can eat JUST so I can have leftovers. What I love even more than leftovers though? Turning them into something completely different!
Yum!! I have only tried making spaghetti pancakes (inspired by Giada) using leftover spaghetti. I usually make just enough for dinner that night. If there are leftovers, I re-create it into something else for lunch the next day. Like you were saying, the same exact thing twice in a row is not too much fun. :/
What a great way to use up the leftover…it sure looks great Pamela…
Have a wonderful week ahead 😀
I love leftovers! We actually almost always eat last night’s dinner for tomorrow’s lunch : ) Very few exceptions! haha What can I say, I hate having to worry about lunches! This leftover casserole looks awesome!
This looks delicious! So cheesy and yummy!! Also, what a great way to use up leftovers!! How creative!
Mmmm. I like leftover spaghetti as leftover spaghetti like you like the tacos. BUT cheese and mushrooms are not to be lightly considered! I might have to rethink my habit. Good redo recipe. Smiles—–
This is a wonderful combination of ingredients Pamela. I can see why your husband loved it!
I love leftovers kmore than food itself, especially if it’s casseroles we’re talking about. This looks incredible my friend! When can I come over for dinner you said?
Such an easy and quick dinner! Love this idea. Nothing like baked cheesy goodness….mmmm…
Yum! Love the mushrooms on top! Love recipes that turn leftovers into something new 🙂
I love getting creative with leftovers. There’s definitely that ‘cooking for a few’ mentality in our home, even though like you we’re just two! Will usually make Spag Bol jaffles in our home, but definitely need to give this casserole a whirl!
For me there are some leftovers that I like and others that… ehhh, no thanks. I seem to always have leftover spaghetti, which I do love to have. This would be a great way to create a new meal from those leftovers. 😀
You probably don’t know how much I love baked spaghetti. I love this and I will be making it.
What a creative way to transform leftovers! I love how you added some mushrooms. Yum!
I’m usually not into leftovers… so the hubby gets them in his lunch. I also don’t think I cook for an army 🙂 Either that or the hubby is an army…because we rarely have more than one lunch of leftovers.
Gorgeous! Loving this!
I ate pasta last night! But with penne…don’t hate me!
I’m so bad at using leftovers… my wife can’t stand it because she hates wasting food. Loving this idea of re-purposing leftovers into a casserole! Then it’s a brand new meal and boom… I’m excited again.
I made this leftover spaghetti casserole & loved it so much, so did my husband Peter!
Yum! This looks great! I love leftovers. We plan our menu around them. Ill have to try this this next time we have spaghetti!
Look at that cheese….omg…..yum.
My Mother made way too much of her famous spaghetti,like two pounds too much! So I googled a quick recipe to see if I absolutely had to use egg,and I decided to after reading most of the recipes with a basic ingredient list called for it.
It was so yummy! I used mozzarella, Parmesan, sharp cheddar,and a little Gouda. I had to combine all my cheeses to have enough to cover the mixture. I put olive oil soaked plum tomatoes on top. Even though my toppings were almost weird, the taste of the filling was great! Lol I loved your presentation in the blue. Leftovers are my favorite!
That sounds so delicious Dawn! I love the addition of the olive oil soaked plum tomatoes, I’ll need to try that once our tomatoes are ready to be picked!
I use this recipe every time we have leftover spaghetti. It is delicious, simple, and affordable. On another note, the website should be ashamed. I had to try 6 times to see the recipe because the pop ups redirected even if you hit the close button.
Hey Marissa, if there’s a specific ad that you see that won’t close, can you please email me a screenshot so I can take care of it? I’m always looking for ways to better improve readers experience! Glad you enjoy this Casserole recipe!
When do you add the sauce?
Hey Suzanna, mix leftover spaghetti noodles and pasta sauce with egg, Italian seasoning, Parmesan cheese and shredded chicken (optional). Hope this helps – enjoy!
