Description

A creamy, cheesy side dish, this Cheesy Spaghetti Squash Gratin combines the natural texture of roasted spaghetti squash with a rich, cheesy sauce for a flavorful, low-carb option.


Ingredients

Scale
  • 1 medium spaghetti squash
  • 2 tablespoons butter
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1/2 cup sour cream
  • 1 cup shredded cheddar cheese, divided
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon paprika
  • 2 tablespoons grated Parmesan cheese

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. Cut the spaghetti squash in half lengthwise and scoop out the seeds. Place the squash halves, cut side down, on a baking sheet lined with parchment paper. Roast for 30–40 minutes, or until the squash is tender and easily pierced with a fork.
  3. Once the squash is cooked, use a fork to scrape the flesh into spaghetti-like strands. Set aside.
  4. In a large skillet, melt butter over medium heat. Add the chopped onion and minced garlic, cooking for 2–3 minutes until softened and fragrant.
  5. Stir in the sour cream, 1/2 cup of cheddar cheese, salt, pepper, and paprika. Cook for another 2–3 minutes until the cheese is melted and the mixture is smooth.
  6. Add the cooked spaghetti squash strands to the skillet, mixing well to combine.
  7. Transfer the mixture to a greased baking dish and top with the remaining 1/2 cup of shredded cheddar cheese and grated Parmesan.
  8. Bake for 15–20 minutes, or until the top is golden and bubbly.
  9. Serve warm and enjoy the creamy, cheesy goodness of this spaghetti squash gratin!

Notes

  • If you’d like a little more crunch, try topping with breadcrumbs before baking.
  • You can substitute the cheddar cheese with any cheese of your choice, such as mozzarella or Gruyère, for a different flavor.
  • For a lighter version, use Greek yogurt instead of sour cream.
