Spaghetti Squash is starting to show up in the stores, so today I am reminding you about this fantastically delicious Roasted Spaghetti Squash with Mizithra Cheese and Browned Butter! If you’re living in the U.S. and you’re familiar with Mizithra Cheese, there’s a good chance you learned about it at The Old Spaghetti Factory, where Spaghetti with Mizithra Cheese and Browned Butter has been the most popular dish since 1969.  I’ve been a long-time fan of this famous dish, but these days a big plate of spaghetti isn’t something I’d splurge on for dinner very often.

That’s why I decided to try to create a version of this iconic recipe that was suitable for a carb-conscious diet. Jake and I first tried using Mizithra and browned butter on zucchini noodles, an experiment that was most definitely not a keeper. Then we had the idea of using Mizithra and browned butter on spaghetti squash.

Oh my, happy tastebuds! The Roasted Spaghetti Squash with Mizithra Cheese and Browned Butter was amazing. Everything about this combination worked perfectly, and when we tested the recipe Jake and I had to use ultimate self control not to eat it all at once!

This low-carb and gluten-free version of The Old Spaghetti Factory’s classic dish would  also be great for Keto, and it’s a perfect side dish for a low-carb meal; enjoy!

Roasted Spaghetti Squash with Mizithra Cheese and Browned Butter is a lower-carb version of the famous Spaghetti with Mizithra Cheese and Browned Butter at The Old Spaghetti Factory!


  • 1 spaghetti squash (see notes)
  • 2 tsp. olive oil
  • salt and fresh ground black pepper to taste
  • 1/3 cup browned butter (see notes)
  • 1/2 cup grated Mizithra Cheese


  1. Preheat oven to 400F/200C.
  2. Spray a baking sheet with oil or non-stick spray.
  3. Pierce the spaghetti squash with a fork and microwave about 5 minutes on high to soften, so it’s easier to cut through the skin. (You can skip this step if you don’t have a microwave, but it does make the squash easier to cut.)
  4. Cut just the very end off each piece of squash, removing the stem.
  5. Cut squash lengthwise into two equal pieces and scrape out the seeds.
  6. Place squash onto the baking sheet and brush the surface with the olive oil.
  7. Season to taste with salt and fresh-ground black pepper.
  8. Roast squash about 50-60 minutes, or until the pieces shred apart easily with a fork to make “spaghetti.”
  9. Larger pieces of squash may take a little more than an hour.
  10. When the squash is done, remove from the oven and use a fork to shred the squash strands apart, keeping them in the serving vessel made by the skin of the squash.
  11. Cut the butter into pieces and place in a small frying pan.
  12. Heat over medium heat until the butter is melted.
  13. Then continue cooking the butter, whisking constantly, until it starts to foam up and turns slightly brown.
  14. The butter should have some brown flecks in the bottom of the pan and smell slightly nutty when it’s done.
  15. You can strain to remove the foam if you wish, although it’s not necessary.
  16. Here’s more about How to Brown Butter if you haven’t done it.
  17. Drizzle the browned butter over the squash and top with desired amount of the grated Mizithra Cheese.
  18. Serve hot, with a little more cheese to pass at the table if desired.


Use a spaghetti squash that's at least 2 1/2 pounds for this recipe. Use just over half of a stick of butter.

Nutritional information is based on a serving size of about one cup of spaghetti squash.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:

  1. I have made this recipe, and it is awesome! I didn’t care for spaghetti squash until I tried this. Thank you for inspiring us with your wonderful recipes! 

  2. Despite living in u.s I did not hear about mizithra cheese. well the recipe is indeed delicious especially with Browned Butter

  3. Mizithra is a Greek cheese that isn’t as popular outside of Greece as feta is. However, it shouldn’t be ignored! It tastes great in so many different types of dishes (such as this one) that it’s worth keeping on hand!

  5. After roasting my spaghetti squash in the oven and shredded my squash, is it normal to still have some moisture/water. My shredded squash is not totally dry. Is this correct?

    • The squash should be a little moist when it's done but not what I would call "wet". Some squash might be a lot moister than others, depending on how long since it was picked. You could roast it a few more minutes if you don't think it's done, but it certainly won't hurt anything.

  6. Mizithra cheese and browned butter are favorites of mine! I look forward to trying it with squash!
