🌟 Ingredients

For the Frittata:

• 2 cups zucchini, sliced (about 14 oz)

• 5 large eggs

• 1 medium onion, finely chopped

• 1/3 cup grated Parmigiano cheese

• 3 tbsp extra-virgin olive oil, divided

• 1/2 tsp salt

• 1/4 tsp black pepper

• A pinch of nutmeg (optional)

👩‍🍳 Method

1. Prepare the veggies:
   Wash and dry the zucchini. Trim ends and slice into rounds. In a large nonstick pan, heat 1½ tablespoons of olive oil and sauté the chopped onion until soft. Add zucchini, sprinkle with salt, and cook over medium heat for 5–6 minutes. Set aside to cool slightly.

2. Make the egg mixture:
   In a large bowl, beat the eggs with salt, pepper, and nutmeg (if using). Stir in the Parmesan cheese.

3. Combine:
   Add the cooled zucchini and onion mixture into the eggs. Mix well.

4. Cook the frittata:
   In the same pan, heat the remaining 1½ tablespoons of olive oil. Pour in the egg-zucchini mixture. Cover with a lid and cook on low heat for about 10 minutes, until the bottom is set.

5. Flip the frittata:
   Place a large flat plate over the pan. Invert the frittata onto the plate, then gently slide it back into the pan to cook the other side. Cook covered for another 8 minutes.

6. Serve:
   Let it rest a few minutes, then slice and serve. Enjoy hot, warm, or cold!

💡 Tips & Tricks

• Don’t overcook the eggs — they should be tender, not rubbery.

• For an oven version: Bake at 350°F (180°C) for 25 minutes until golden.

• Add-ins: Try adding a handful of fresh herbs like basil or parsley.

• Make it cheesy: Add cubes of mozzarella for an even richer flavor.

• Storage: Refrigerate leftovers in an airtight container for up to 2 days.
