Spaghetti Squash is starting to show up in the stores, so today I am reminding you about this fantastically delicious 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! 

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 not a keeper. Then we had the idea of trying it on spaghetti squash, and oh my, happy tastebuds! The 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!

What ingredients do you need for this recipe?

 What is Spaghetti Squash?

Spaghetti Squash is a type of winter squash that’s popular with vegetable gardeners. It’s famous for the way the cooked squash strings apart in strings, resembling spaghetti. And if you grow your own spaghetti squash you can also cook unripe spaghetti squash as a summer squash, which is one of my personal favorites!

What is Mizithra Cheese?

Mizithra Cheese is a type cheese that comes from Greece or the Island of Crete. It’s most often sold as an aged, hard cheese that’s grated like Parmesan. It has a distinctive nutty flavor, and in the United States this cheese was made famous by The Old Spaghetti Factory, where Spaghetti with Mizithra Cheese and Browned Butter has been the most popular dish since 1969.

What is Browned Butter?

Browned Butter is simply butter that’s cooked until it foams and the milk fat darkens and develops a nutty flavor. Here is How to Brown Butter if you’ve never tried it.

Do you have to roast the spaghetti squash?

Roasting dries out the spaghetti squash a bit and we loved the roasted spaghetti squash in this dish. But you can also cook the spaghetti squash in the Instant Pot or the Slow Cooker if you prefer.

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.
