Ingredients for Onion Cheese Frittata Recipe

For the frittata (serves 4 as a main or 6 as a side):

  • 2 red onions, thinly sliced
  • 1/4 cup olive oil or butter
  • 6 large eggs
  • 1 cup shredded mozzarella or sharp cheddar cheese
  • 2 tablespoons chopped fresh herbs (parsley, chives, or green onions)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Pinch of red pepper flakes (optional)
  • Fresh herbs for garnish

Estimated time: 5 minutes prep + 5 minutes cook

Why these exact amounts? The sliced red onions add sweetness and color while the eggs and cheese create a custard that sets into a light, fluffy texture with that signature golden crust.

How to Make Onion Cheese Frittata Recipe

Heat a 10-inch non-stick skillet over medium heat. Add the olive oil or butter and swirl to coat the bottom. Add the sliced red onions and cook for 3 to 4 minutes, stirring occasionally, until they soften and start to turn golden at the edges. Season lightly with salt and pepper.

Pour the beaten eggs evenly over the onions. Sprinkle the shredded mozzarella and chopped herbs on top. Tilt the skillet gently to let the eggs spread evenly and the cheese settle.

Cook for 4 to 5 minutes without stirring until the edges pull away from the pan and the bottom is set. You will see the edges lifting slightly. For a fully set frittata, cover with a lid and cook for another 1 to 2 minutes until the center is just set but still slightly jiggly in the middle.

Slide a spatula around the edges to loosen the frittata. Flip it onto a plate or serve straight from the skillet. Let it rest for 1 minute. The onion cheese frittata recipe tastes even better when sliced and served warm with fresh fruit or salad on the side.

Pro tip: Use a well-seasoned cast-iron or non-stick skillet for the best release and golden edges. If the frittata sticks, run a thin knife around the edges before flipping.
