This super easy Slow Cooker Spaghetti Squash with Meatballs is just 3 ingredients and takes very little prep work.
You can use jarred spaghetti sauce (or homemade marinara) as well as frozen prepared meatballs (or homemade meatballs).
Spaghetti squash is a type of garden squash that, when roasted or cooked, the filling resembles spaghetti noodles. It’s a great low-carb alternative to pasta.
Slow Cooker Spaghetti Squash
So the other day I was browsing Instagram and came across my friend’s photo of her son (who is 3, I believe) seasoning a couple spaghetti squash that were sitting in a crock pot. I was intrigued, so I asked for the recipe.
If you’re looking for an excellent way to prepare spaghetti squash that’s low-fuss and full of flavor, this recipe is for you.
Ingredients Needed
You only need three ingredients to whip up this incredibly easy dinner using spaghetti squash. As always, you can find the full list of ingredients located in the printable recipe card below.
- Spaghetti Squash – medium to large size, it should fit in your slow cooker.
- Marinara Sauce – use my homemade version or your favorite jarred sauce.
- Meatballs – you can make homemade meatballs* (see notes below) or frozen meatballs for extra ease.
How To Make It
Start by cutting a thoroughly washed spaghetti squash in half and scooping out the seeds and membranes.
Place the spaghetti squash cut side down into the crock pot, then pour in a jar of your favorite spaghetti sauce (you’ll need at least 24oz or 3 cup of homemade).
PRO TIP: If you like it extra saucy, you can add more sauce at this point.
Then toss in some frozen meatballs. I used an Italian style beef meatball, but feel free to adjust that to your liking too.
Can I Cook Raw Meatballs in Slow Cooker?
Yes! You can definitely make homemade meatballs and then place them in the slow cooker to finish cooking. I would recommend searing the meatballs first so they hold their shape better after being cooked.
How Long To Cook Spaghetti Squash in Slow Cooker?
Cook the spaghetti squash in the slow cooker on LOW for 5 hours, or HIGH for 3 hours.
Use some tongs to pull out the squash onto a cutting board, then use a fork to pull out the delicious insides. Discard the shell of the squash.
What’s left in the crock pot is the sauce and meatballs, ready for you to dress your spaghetti squash.
The squash is so tender and moist, and seriously resembles the texture of spaghetti noodles when cooked like this, but as an added bonus – it’s vegetables, NOT carb-riddled pasta, so eat up and enjoy!
Make Ahead and Storage
This recipe for spaghetti squash in the slow cooker tastes best when it’s made and prepared initially. The squash can get a little mushy once stored and reheated, but still tastes great.
Store any leftovers in the fridge for up to 5 days.

Made this tonight. Excellent and so easy. TFS
My partner and I are vegetarians and I made this with vegan meatballs. Delicious!
Awesome! So glad you enjoyed it! 🙂
Brilliant! I love it!
Thanks Jean!
Mad this for dinner last night and it was fantastic! Totally my new favorite!
Made not mad haha 🙂
Hmmm I’ve been meaning to try spaghetti squash. I’m not a huge fan of meatballs though, may have to try ground beef. That alfredo suggestion may also be tried 🙂
This was so amazingly tasty! We have had spaghetti squash before in the oven. This is WAAY easier!! It was so good our picky 4 year old devoured it!!! This is being added to our monthly dinner recipes!!! 🙂 THANK YOU!!
Thanks Michelle! I still think cooking it in the crockpot is the BEST way!! 🙂 Glad you guys enjoyed it! 🙂
Made this tonight…my first time cooking spaghetti squash. I bought a small crock pot so I only made half but it was plenty for the two of us! My fiancé and I both enjoyed it very much and will be eating this again as well as other variations. Thank you!
My wife and I used to bake the whole thing. It’s a lot easier to cut it in half, take out the seeds, and put in a crock pot. It was a much better consistency and there is no difficulty removing the skins later.
I’m trying this today with chicken. I cut up skinless chicken breast and threw in some left over mushrooms. I replaced pasta with spaghetti squash a long time ago, but never cooked it in the crock pot. Lots of variations in mind!
That sounds wonderful! 🙂
My squash was also too big for my 6 quart oval slow cooker. One half is in the crockpot now and I’m just going to bake the other half face down for about an hour right before dinner. I’ll probably also saute the squash with some butter and Italian seasoning before topping it with the sauce and meatballs. Super excited for dinner tonight!
Sounds yummy! I was also thinking brats and onion or some other sausage?
That sounds like a great idea!
Well, I’ve tried this twice now. I love how easy it is! I love that my kids love spag squash. What I don’t love are the meatballs! This is not your fault not the fault of the recipe. I cannot for the life of me find good meatballs. I’ve tried two different brands and both were mealy and strange tasting. Help! I truly love this recipe. What meatballs are y’all using?
Use homemade. I hate frozen meatballs.
So u freeze the homemade ones raw then put them in the crock? Or cook then freeze?
Try some good sausage to replace meat balls
I’ve done this with Turkey Italian sausage links….so good!
I’ve used turkey Italian sausage links or added brouned ground turkey to the sauce the last hour.
Try the fresh made meatballs in your local grocer. Publix and Kroger have great meatballs. Sprouts, too! But what I have learned is they also make fresh “meatloaves” and it is cheaper to buy those and shape into meatballs. If you read the packaging, it is the same product in a different form! And another great tip… If you like to cook your meatballs first, throw them on a George Forman type grill and pull the cover down. They brown all over quickly and all the fat drains off!!! 🙂
