Ingredients

Scale
  • 1 medium spaghetti squash
  • 1 tbsp olive oil
  • ½ cup diced onion
  • 2 cloves garlic (minced)
  • ½ cup plain Greek yogurt (or sour cream)
  • 1½ cups shredded sharp cheddar cheese (divided)
  • ¼ tsp salt
  • ¼ tsp black pepper
  • Optional: ¼ tsp paprika or dried thyme

Instructions

  1. Preheat oven to 400°F (205°C). Halve the spaghetti squash lengthwise and scoop out the seeds. Brush cut sides with olive oil, place face-down on a baking sheet, and roast for 35–40 minutes until tender.
  2. While roasting, sauté onions in olive oil over medium heat for about 5 minutes, then add minced garlic and cook for an additional minute.
  3. Once cooled, shred the roasted squash into noodle-like strands using a fork.
  4. In a large bowl, combine shredded squash with sautéed onions and garlic, Greek yogurt (or sour cream), 1 cup of shredded cheese, salt, pepper, and optional spices.
  5. Transfer to a greased casserole dish and top with remaining cheese. Bake at 375°F (190°C) for 20–25 minutes until bubbly and golden brown.
  6. Allow to cool slightly before serving.
