Ingredients

• 1 large red onion
• 2 tablespoons olive oil
• 8 eggs
• 0.25 cup whole milk
• 0.5 cup feta cheese
• 2 tablespoons fresh parsley (chopped)
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper
• 1 tablespoon unsalted butter

Directions

Step 1

Preheat oven to 375°F (190°C).

Step 2

Peel and thinly slice the red onion.

Step 3

Heat olive oil in a medium oven-safe skillet over medium heat. Add the sliced red onion and cook for 7-8 minutes, stirring occasionally, until caramelized and soft. Remove from heat and set aside.

Step 4

In a large mixing bowl, whisk together the eggs, whole milk, salt, and black pepper until well combined.

Step 5

Stir in the caramelized red onions, crumbled feta cheese, and chopped fresh parsley.

Step 6

Place the same skillet back on the stove over medium heat and add the unsalted butter, allowing it to melt and coat the bottom of the pan.

Step 7

Pour the egg mixture into the skillet and cook for 2-3 minutes, until the edges begin to set.

Step 8

Transfer the skillet to the preheated oven and bake for 15-18 minutes, or until the frittata is puffed and the center is just set.

Step 9

Remove from the oven and let the frittata cool for 5 minutes before slicing into wedges.

Step 10

Serve warm and garnish with additional parsley or feta, if desired.
