Onion Frittata: Italy’s Simple & Flavorful Omelet

This recipe is a true gem for anyone who loves quick, budget-friendly, and incredibly aromatic meals. The Savory Onion Frittata is made with just a few core ingredients, yet the flavor is surprisingly rich and complex: the mellow sweetness of slow-cooked onions, the creamy tenderness of the eggs, and the sharp, salty notes of real Parmesan cheese. It’s perfect for a weekend brunch, a light lunch, or a simple weeknight dinner.


Ingredients:

  • 3 large white onions
  • 8 large eggs
  • 100 g (about 1 cup) grated Parmesan cheese (or another hard cheese if adapting the recipe)
  • Extra virgin olive oil
  • Salt, to taste
  • Ground pepper, to taste

Instructions:

  1. Prepare the Onions:

    • Peel the onions and slice them into thin half-rings or small pieces—whichever you prefer.

    • Heat a large skillet with a generous amount of olive oil and sauté the onions over very low heat until they are completely soft and acquire a sweet, caramelized flavor. This step is key to the frittata’s flavor!

  2. Whip the Eggs:

    • In a bowl, crack the eggs. Season with salt and pepper, and add the grated Parmesan cheese.

    • Whisk thoroughly until the cheese is evenly distributed throughout the egg mixture.

  3. Combine and Cook:

    • Once the onions are soft and translucent, pour the egg and cheese mixture over them.

    • Gently stir to combine the ingredients evenly, then cover the pan with a lid.

    • Cook for about 5 minutes over low heat until the omelet is set but the top is still slightly moist.

  4. Finish the Frittata:

    • Carefully flip the frittata (you can use a large plate to assist) and brown the other side for a couple of minutes.

    • Remove from the pan and serve warm.

Your Onion Frittata is ready! Buon Appetito!
