Say hello to what might be Creighton’s favorite recipe of all time. Just watch my Instagram stories for this recipe. At the end, you will see his love for this recipe. He says it’s like a cheesy meatball sub sandwich only minus the carb-heavy bread (which he tries to avoid).

I’m not sure why he refers to a meatball sandwich and not pasta, but whatever the case, Creighton thinks this is his favorite recipe to date. He’ll be watching the video of this recipe tonight and wishing so badly he could eat this again for dinner.

There’s certainly a lot of all-around love for this recipe. It’s going to be a hard one to top.

I certainly don’t think meatballs and spaghetti squash are a new concept by any means. It’s the way I’ve cooked everything together that I think is a little more special. And while the recipe takes over an hour to create, it’s mostly just time allowing the squash to roast in the oven. This will typically take anywhere from 30-45 minutes depending on the size.

The process is actually relatively simple. Bake the squash with cheese. Then while the squash gets a head start in the oven, mix and form the meatballs. Then add the meatballs to the pan, and cook again.

Using the roasted garlic, make a garlic butter. Then slather it all over the cheesy meatballs and the squash. Use a fork to scrape up the squash and enjoy this wonderful goodness.

Onto the finer details

Step 1: mix the cheese sauce

I love to use a blend of fontina, mozzarella, provolone, and parmesan. Sometimes I’ll use a gouda in place of fontina. It’s a really nice mix of creamy cheeses, but the provolone adds all the flavor, so don’t skip that one. Of course, you can also use your own favorite blend of cheese. Or even pick up a pre-shredded mix from the store to keep things really easy.

Mix the milk with the mozzarella cheese, spinach, and sun-dried tomatoes. This is our cheese sauce.

Step 2: season and stuff the squash

Ideally, find two smaller spaghetti squash. Think of each half as a personal spaghetti squash boat.

Cut the squash in half, pull the seeds out, and place the squash on a sheet pan. Now season with salt and pepper, add the parmesan cheese, and then the cheese mixture from above.

Arrange a handful of garlic around the squash, then bake everything to get the squash cooking.

Step 3: mix the meatballs

I make mine using ground chicken, Italian seasoning, dijon, and parmesan cheese. Just mix everything together and roll it into meatballs.

Pull the squash from the oven and add the meatballs to the pan. Bake again to cook the meatballs while the squash continues to cook.

Step 4: add cheese and mix the garlic butter

Grab the pan from the oven one last time. This time remove the garlic from the pan. Set the garlic aside.

Next, top the squash with additional cheese and place the cooked meatballs into/on top of the squash. Bake to melt the cheese.

While the squash and meatballs are cooking in the oven, chop the roasted garlic, then mix it with butter and fresh herbs. I love to use a mix of basil, oregano, thyme, and sage.

When you pull everything out of the oven, don’t be worried that the sauce looks soupy. Once you scrape the squash into strands of spaghetti and mix it together with the sauce it’s so delicious.

Spread the garlic butter over the meatballs and mix the rest into the squash. Use a fork to pull the squash into spaghetti. The smell alone will make you so excited.

This is a great recipe for busy weeknights when you want something warm and cozy, but still full of protein and vegetables.

Or serve this up to guests at your next dinner gathering. Either way, it’s perfect for autumn!

  • 1. Preheat the oven to 425° F.
    2. In a bowl, mix together the milk, spinach, tomatoes, and mozzarella. Season with chili flakes, salt, and pepper.
    3. Place the squash on a baking sheet and season the cut sides with salt and pepper. Sprinkle 1/4 cup parmesan cheese into the bottom of each squash. Then evenly divide the milk/cheese mix among the squash cavities. Cover with foil, bake 15 minutes.
    4. Meanwhile, mix the chicken, Italian seasoning, dijon, and 1/2 cup parmesan in a bowl. Season with salt and pepper. Mix to combine. Coat your hands with oil, and roll the meat into tablespoon-size balls (makes 15-16 meatballs).
    5. Remove the squash from the oven, remove the foil. Arrange the meatballs around the squash. Bake another 15 minutes, until the meatballs are cooked.
    6. Grab the squash. Remove the garlic from the pan. Sprinkle the provolone cheese over each squash half. Put the meatballs on top of the cheese. Bake for 10-15 minutes, until the cheese is melted.
    7. Chop the garlic and mix with the butter and herbs in a bowl. Spread the butter over the meatballs, then use a fork to scrape the squash into strands, mixing the cheese with the squash. Enjoy!


Roasting the Squash: if your squash is on the larger side, pre-roast it for 20-30 minutes before adding the cheese mixture.

    1. Hi Anne,
      So sorry for any confusion, you are going to add the garlic to the pan in step 5 and then remove in step 6 and chop in step 7. I hope this helps! xT

    What a delicious meal this made. I’m always trying new dishes and this is a keeper! Now here come the changes: I decided to not use the butter sauce, because the dish has plenty of cheeses and cream to tantalize our taste buds. Also, I couldn’t find sun-dried tomatoes the day of shopping, so I used a tomato pesto that worked out just fine. We’re big fans of this recipe!

    1. Hi Kathy,
      Wonderful!! I appreciate you trying this recipe and sharing your feedback! So glad it was enjoyed:) xT

    I think this could be a fantastic recipe. I would reduce the cream by half and add chix broth. I recommend roasting squash face down first for 15-20 mins. It was good but squash was still firm.

    1. Hi there,
      Thanks for trying this recipe and sharing your feedback! Sorry to hear the squash was still firm for you! xx

  3. I’m so confused. The simple instructions seem to be missing steps, it mentions removing garlic from pan but no mention of when or what to put on the pan??

    Loved this- everyone said the filling was their favorite. Next time I will double that part. I made extra meatballs as well and they went quickly. The directions are a little confusing, so I baked the spaghetti squash first for about 40 minutes then added the fillings and baked again for 15-18 minutes. We just cut the filled halves in half and served them that way with the butter herb sauce on top. Gorgeous & delicious.

    Wow!! Don’t forget to put the garlic in at the beginning! I also used wilted fresh spinach instead of frozen. But sooooo good! Cheesy and flavorful! Worth the time to make
