  4. Place the squash halves cut-side down on a baking sheet.

  6. Let the squash cool slightly, then use a fork to scrape out the strands.
  7. In a bowl, combine the spaghetti squash strands, heavy cream, Parmesan cheese, Gruyere cheese, cheddar cheese, minced garlic, salt, and pepper.
  8. Mix well to combine.
  9. Transfer the mixture to a greased baking dish.

Notes

  • For a richer flavor, you can add a pinch of nutmeg to the squash mixture.
  • If you don’t have Gruyere, Swiss cheese can be substituted.
  • This dish pairs well with roasted chicken or pork.
  • Consider this a healthy alternative to traditional potato gratins.
