Description

A deliciously creamy and healthy twist on traditional au gratin, featuring spaghetti squash as a low-carb alternative.


Ingredients

Scale
  • 1 medium spaghetti squash (about 3 lbs)
  • 1 tbsp olive oil
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tbsp butter
  • 1 cup shredded sharp cheddar cheese (divided)
  • ½ cup Parmesan cheese, grated
  • ½ cup Greek yogurt or light sour cream
  • ½ cup milk (or unsweetened almond milk for low-carb)
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp nutmeg (optional, for warmth)
  • Fresh parsley or basil, for garnish

Instructions

  1. Preheat the oven to 400°F (200°C).
  2. Cut the squash in half lengthwise and scoop out the seeds.
  3. Drizzle with olive oil, season lightly with salt and pepper.
  4. Place cut side down on a baking sheet and roast for 35–40 minutes, until tender.
  5. Let it cool slightly, then use a fork to shred the flesh into “noodles.”
  6. In a skillet, melt butter and sauté onion until soft (about 3–4 minutes).
  7. Add garlic and cook for another 30 seconds.
  8. Stir in milk, Greek yogurt, and half the cheddar and Parmesan.
  9. Mix until melted and creamy, season with salt, pepper, and nutmeg.
  10. In a bowl, toss spaghetti squash strands with the creamy cheese mixture until well coated.
  11. Transfer to a greased baking dish.
  12. Top with the remaining cheddar and Parmesan.
  13. Bake uncovered for 20–25 minutes, until bubbly and golden on top.
  14. Serve hot, garnished with chopped parsley or basil.

Notes

  • Add cooked bacon, ham, or sautéed mushrooms for extra flavor.
  • To make it keto, use heavy cream instead of milk.
  • For a spicier version, sprinkle with red pepper flakes before baking.
