Spinach Leek and Feta Cheese Frittata

Spinach, Leek and Feta Cheese Frittata is everything!  It cooks up in one pan, is perfect for any meal and can be ready in about 30 minutes.  It's a Greek-inspired version of Italy's answer to the French omelet!

Ingredients

  • 1 tablespoon butter
  • 1 tablespoon olive oil
  • 1 large leek white and light green part only, halved and thinly sliced (about 1 cup)
  • 1 container (5-6 ounce) baby spinach
  • 1 clove garlic minced
  • salt and freshly ground black pepper to taste
  • 1 teaspoon chopped fresh dill or 1/2 teaspoon dried dill
  • 1/3 cup crumbled feta cheese
  • 3 large eggs
  • 3 large egg whites
  • 2 tablespoons milk

Instructions

  • Position an oven rack about 6-8 inches from the broiler. Preheat broiler.
  • Heat butter and olive oil over medium heat in an 8-inch oven and broiler-safe sauté pan. Add the leeks and reduce heat to medium-low. Cook the leeks very slowly for 15 to 20 minutes, stirring often, or until very soft, being careful not to brown them.
  • Add the spinach and garlic and cook 1 to 2 minutes or until the spinach is wilted. Stir in salt, pepper and dill. Distribute leek and spinach mixture evenly over the bottom of the pan and sprinkle with feta cheese.
  • Combine the eggs, egg whites and milk in a bowl and whisk to blend. Pour the egg mixture into the sauté pan.
  • Allow the egg mixture to cook slowly and with a heat-resistant spatula, gently move the egg mixture around without scrambling the mixture. When the edge of the frittata is beginning to hold together, transfer the pan to the broiler. Broil for 2 to 4 minutes or until the top is set and beginning to lightly brown.
  • Cut into wedges and serve.

Notes

I used a very well-seasoned cast-iron skillet. If your cast-iron skillet is not well-seasoned, use a stainless steel skillet.
SUBSTITUTIONS:
  • Use any greens:  Kale, Swiss chard, or arugula.
  • Use goat cheese in place of feta.
TIP:
  • Add additional heartiness to this frittata by adding leftover cooked potatoes.
FREEZER-FRIENDLY:
  • Cut the frittata into pieces and freeze on a baking sheet.  When solid, transfer to an airtight container or freezer bag.
  • To reheat, thaw in the refrigerator then reheat in the microwave or wrapped in foil in the oven or toaster oven at 300 degrees until heated through.
