Spaghetti Squash Au Gratin

If you like Potatoes Au Gratin, then you’ll love this spaghetti squash variation. It has the same great flavor and creamy texture, but without the the white potatoes. This side dish goes well with almost any meat you pair it with, and kids will love it too! This recipe is adapted from Dandy Dishes.

spaghetti squash augratin


  • 1 medium spaghetti squash
  • 2 tablespoons grass-fed butter (we recommend Kerrygold brand – available at Trader Joe’s or Dierberg’s)
  • 1 small yellow or white onion, very thinly sliced
  • ¼ teaspoon red pepper flakes
  • 1 teaspoon fresh thyme
  • ½ cup sour cream
  • ½ cup shredded cheddar cheese


  1. Cut the spaghetti squash in half and scoop out the seeds.  Place in a covered microwave safe dish with a ¼ inch of water and microwave for 10 -12 minutes.
  2. Heat a skillet over medium heat. Add the butter, onions, red pepper and thyme. Cook until the onions are slightly brown in color.  Season with salt and pepper to taste.
  3. Begin preheating the oven to 375ºF
  4. After allowing the spaghetti squash a few minutes to cool, use a fork to scrape the “noodles” into a small bowl.
  5. Combine the squash, onions, sour cream and half of the cheese together and mix well.
  6. Transfer the mixture to a buttered baking dish and top with remaining cheese.
  7. Bake at 375º for 15 – 20 minutes, until the top is golden brown.

Tip: If you like things spicy try adding some extra red pepper flakes!
