For the crust:

  • 1 medium spaghetti squash
  • 3 tbsp Kosterina Everyday Extra Virgin Olive Oil
  • 1 egg
  • ½ tsp garlic powder
  • ½ tsp kosher salt
  • salt and pepper to taste

For the filling: 

  • 4 eggs
  • ⅔ cup milk
  • 2 tomatoes, chopped 
  • ½ cup crumbled feta cheese
  • 2 tbsp fresh chives, minced  
  • ¼ tsp garlic powder
  • ¼ tsp salt 
  • ⅛ tsp black pepper 
  • 2 tsp Kosterina Original Extra Virgin Olive Oil 


  1. 1

    Preheat the oven to 400 F and line a baking tray with parchment paper. Cut the spaghetti squash in half lengthwise, then use a spoon to scoop out the seeds. Drizzle both halves with 1 tbsp Kosterina Everyday Extra Virgin Olive Oil, season with salt and pepper to taste, and place the cut side down on the lined baking tray. Bake for 30 minutes.

  2. 2

    Once the spaghetti squash has cooled, use a fork to separate into strands. Use a mesh strainer or cheesecloth to strain the excess liquid from the squash. 

  3. 3

    Add the spaghetti squash to a bowl with the remaining 2 tbsp Kosterina Everyday Extra Virgin Olive Oil, egg, garlic powder, kosher salt, and pepper to taste. Press into a quiche or pie dish and return to the oven to bake at 400 F for 25-30 minutes until lightly golden brown. Let cool. 

  4. 4

    In a medium bowl, whisk together the eggs and milk until smooth. Add the tomatoes, feta, chives, garlic powder, salt, and black pepper and mix until completely combined. 

  5. 5

    Lower the oven heat to 375 F. Pour the filling into the spaghetti squash crust and bake for 35-40 minutes or until set.

    Before serving, drizzle with Kosterina Original Extra Virgin Olive Oil.
