These easy muffin tin frittata bites combine salty feta, tender spinach, and fluffy eggs for a quick, protein-packed breakfast or snack that’s perfect for busy mornings or casual brunches.

Ingredients

Scale
  • 8 large eggs (room temperature)
  • 2 cups fresh spinach, roughly chopped
  • 1/2 cup crumbled feta cheese
  • 1/4 cup milk (whole or 2%)
  • 1 clove garlic, minced (optional)
  • 2 tablespoons finely chopped onion (yellow or white)
  • Salt and freshly cracked black pepper to taste
  • 1 tablespoon olive oil or butter for sautéing
  • Pinch of dried oregano or fresh dill (optional)

Instructions

  1. Preheat your oven to 375°F (190°C) and lightly grease your muffin tin with butter or cooking spray.
  2. Heat olive oil or butter in a non-stick skillet over medium heat. Add chopped onion and minced garlic, cooking for 2-3 minutes until fragrant and translucent.
  3. Add chopped spinach and cook for another 2 minutes until wilted but still bright green. Remove from heat and let cool slightly.
  4. In a medium bowl, whisk the 8 large eggs with the milk until smooth and slightly frothy. Season with salt, pepper, and optional herbs.
  5. Fold the sautéed spinach mixture and crumbled feta cheese into the egg mixture, stirring gently to combine.
  6. Pour the egg mixture evenly into the 12 muffin cups, filling each about 3/4 full.
  7. Bake in the preheated oven for 18-22 minutes. Check doneness by inserting a toothpick into the center; it should come out clean.
  8. Let the frittata bites cool in the pan for 5 minutes before removing carefully. Serve warm or at room temperature.

Notes

Sauté spinach and onions first to remove excess moisture and prevent soggy frittatas. Let eggs come to room temperature before mixing for better fluffiness. Cover with foil if tops brown too quickly. These freeze well and reheat nicely.
