Ingredients

  • 6 eggs
  • Salt and freshly ground black pepper
  • 1 tablespoon olive oil
  • 8 ounces white button mushrooms sliced
  • 10 ounces fresh spinach
  • 6 ounces crumbled feta cheese

Instructions

  • Preheat oven to 375°F. Coat a muffin tin with nonstick cooking spray. In a medium bowl (ideally with a spout), beat eggs and salt and pepper to taste (I like 1/2 teaspoon salt and 1/4 teaspoon pepper). Set aside.
  • In a large skillet over medium-high heat, heat oil until shimmering. Add mushrooms and ¼ teaspoon salt and cook until softened and the mushrooms have released most of their liquid, about 5 minutes.
  • Using a slotted spoon, remove mushrooms from skillet to a mixing bowl, leaving any remaining oil and liquid in the skillet.
  • To the skillet with the liquid, add spinach and 1/4 cup of water. Cook spinach until wilted, about 5 minutes.
  • Add the spinach to the bowl with the mushrooms. Stir in the cheese. Divide the mixture evenly among 12 muffin cups.
  • Divide the beaten egg mixture among the muffin cups, filling each nearly to the top. Bake until a toothpick inserted comes out clean, about 25 minutes.
  • Cool slightly before removing from muffin tins (the egg cups should come out easily). Serve hot or at room temperature. Store leftovers in the refrigerator and use within 4 days.

Notes

  • Yield: Makes 12 egg muffins
  • Storage: Store leftovers covered in the refrigerator for up to 4 days.
  • Freezer: Cool and transfer to a single layer on a plate. Freeze until solid, at least 30 minutes, then transfer to a freezer-safe bag. Freeze up to 2 months. Microwave them straight from the freezer until heated through, about 1 minute.
