Ingredients

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

Instructions

  1. Preheat the oven to 400°F (205°C).
  2. Slice the spaghetti squash in half lengthwise and scoop out the seeds. Brush cut sides with olive oil and roast face-down on a baking sheet for 35–40 minutes until tender.
  3. While roasting, heat olive oil in a skillet and sauté diced onions until softened, about 5 minutes. Add minced garlic and cook for another minute.
  4. Once the squash has cooled slightly, shred it using a fork into noodle-like strands.
  5. In a large bowl, combine shredded squash, sautéed onions and garlic, Greek yogurt, 1 cup of shredded cheese, salt, and pepper.
  6. Transfer the mixture to a greased casserole dish and top with remaining cheese.
  7. Bake at 375°F (190°C) for 20–25 minutes until bubbly and golden on top.
