Ingredients Method Notes

Ingredients
  

Main Ingredients
  • 5 large eggs
  • 1 small yellow onion thinly sliced
  • 1 medium zucchini thinly sliced
  • 1 medium yellow squash thinly sliced
  • 2 tbsp extra virgin olive oil
  • 0.25 cup heavy cream optional, for fluffier texture
  • salt to taste
  • black pepper to taste
  • garlic powder to taste
  • 0.25 cup Parmesan cheese grated
  • fresh herbs optional, for garnish (such as parsley or chives)

Method
 

Cooking Instructions
  1. Preheat the oven to 375°F (190°C).
  2. Heat olive oil in a large oven-safe skillet over medium heat. Add the sliced onion and cook for 3–4 minutes until translucent.
  3. Add zucchini and yellow squash to the skillet. Cook for 5–7 minutes until tender and lightly browned. Season with a pinch of salt and pepper.
  4. In a medium bowl, whisk together eggs, heavy cream (if using), salt, black pepper, and garlic powder.
  5. Pour the egg mixture over the vegetables in the skillet, gently stirring to distribute evenly. Cook for 2–3 minutes on the stovetop until the edges begin to set.
  6. Sprinkle Parmesan cheese on top. Transfer skillet to the oven and bake for 10–15 minutes, or until the frittata is fully set and lightly golden. Optionally, broil for 2–3 minutes for deeper browning.
  7. Remove from the oven and let rest for 5 minutes before slicing. Garnish with fresh herbs if desired and serve warm.

Notes

  • Do not overbeat the eggs, as this can make the texture rubbery.
  • Use a cast-iron or oven-safe skillet to ensure even cooking.
  • Resting before slicing helps the frittata hold its shape.
