Caramelized Onion Frittata

caramelized onion frittata in a blue cast iron skillet topped with baby kale, feta and caramelized onions
  • Serves:  8
  • Prep Time:  10 min
  • Cook Time:  1 hr 5 min

Ingredients

  • 8 large eggs, beaten
  • ⅓ cup heavy cream
  • 1 teaspoon sea salt
  • ½ teaspoon freshly cracked black pepper
  • ¼ cup chopped fresh chives
  • 6 ounces feta cheese, crumbled
  • 2 tablespoons extra-virgin olive oil
  • 4 cups baby kale (about 5 ounces)
  • 1 cup caramelized onions

Method

  1. Preheat the oven to 400°F with a rack in the center position.

  2. In a large bowl, combine the eggs, cream, salt, pepper, chives, and two-thirds of the feta.

  3. Heat the olive oil in a medium ovenproof skillet over medium heat. Once the oil is glistening, add the kale and cook, stirring, until wilted, about 2 minutes. Stir in the caramelized onions until well incorporated. Carefully pour in the egg mixture and cook, undisturbed, until the edges are just set, about 2 minutes.

  4. Transfer the skillet to the oven and bake until the eggs are completely set, about 10 minutes. The eggs shouldn’t move when you jiggle the pan.

  5. Top the frittata with the remaining feta. Slice into 8 wedges and serve.
