How to Make Spaghetti Squash Gratin

Ingredients:

  • 1 medium spaghetti squash
  • 1 tablespoon olive oil
  • 1/2 cup diced yellow onion
  • 2 cloves garlic, minced
  • 1/2 cup plain Greek yogurt or sour cream
  • 1 1/2 cups shredded sharp cheddar cheese, divided use
  • 1/4 teaspoon fine salt
  • 1/4 teaspoon ground black pepper
  • 1/4 teaspoon paprika or dried thyme (optional)

Directions:

  1. Preheat your oven to 400°F (205°C).
  2. Slice the spaghetti squash in half lengthwise and remove the seeds with a spoon.
  3. Brush the cut sides of the squash with olive oil. Place the squash halves cut-side down on a baking sheet and roast them for about 35 to 40 minutes, until they are tender.
  4. While the squash is roasting, heat a skillet over medium heat. Add a small amount of olive oil and sauté the diced onion for about 5 minutes until it softens. Stir in the minced garlic and cook for 1 more minute before removing from heat.
  5. Once the squash is cool enough to handle, use a fork to scrape out the flesh and create noodle-like strands.
  6. In a large mixing bowl, combine the shredded squash, sautéed onion and garlic, Greek yogurt (or sour cream), 1 cup of shredded cheddar, salt, pepper, and optional paprika or dried thyme.
  7. Spread this mixture in a greased casserole dish and sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top.
  8. Lower the oven temperature to 375°F (190°C). Bake the casserole for 20 to 25 minutes, until it is hot and bubbly with a golden cheese crust.
  9. Let the casserole cool briefly before serving. Enjoy it as a side or a light main dish.
