Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Lightly coat a standard 6-cup muffin tin with 1 tbsp olive oil using a brush, ensuring even coverage.
  2. Step 2: Whisk 6 large eggs in a medium bowl until fully blended and slightly frothy, about 1 minute, then stir in 1/4 tsp salt and a pinch of black pepper.
  3. Step 3: Fold in 1/2 cup finely chopped spinach, 1/4 cup crumbled feta, 1/4 cup grated mozzarella, and 1/4 tsp garlic powder until evenly distributed with a rubber spatula.
  4. Step 4: Divide the egg mixture evenly among the greased muffin cups, filling each 3/4 full to allow for rising.
  5. Step 5: Bake for 18-20 minutes until the edges are deeply golden and the centers spring back when gently pressed with a fingertip.
  6. Step 6: Let cool in the tin for 5 minutes before transferring to a wire rack to set completely, ensuring crisp edges without sogginess.
