Ingredients
- 6 large eggs
- 1/4 cup milk (dairy or plant-based)
- 1 cup fresh spinach, chopped
- 1/3 cup crumbled feta cheese
- 1/4 cup finely diced red bell pepper
- 2 tablespoons chopped green onions
- 1/2 teaspoon dried oregano
- 1/4 teaspoon garlic powder
- Salt and freshly ground black pepper, to taste
- Non-stick cooking spray or a little olive oil, for greasing
Instructions
-
Preheat your air fryer to 320°F (160°C).
-
In a medium bowl, whisk together the eggs and milk until smooth and slightly frothy.
-
Stir in the chopped spinach, crumbled feta, red bell pepper, green onions, dried oregano, garlic powder, salt, and pepper until evenly combined.
-
Lightly grease six silicone or metal muffin cups or ramekins with non-stick cooking spray or olive oil.
-
Divide the egg mixture evenly among the prepared cups, filling each about three-quarters full to allow room for rising.
-
Carefully place the filled cups into the air fryer basket or tray, spacing them to allow even air circulation.
-
Air fry at 320°F (160°C) for 12-15 minutes, or until the quiche cups are set in the center and lightly golden on top. Test doneness by inserting a toothpick; it should come out clean. Check the center reaches 160 F (71 C).

Remove the cups carefully using tongs or a spoon and allow them to cool for a minute or two before removing from the cups.
-
Serve warm as a delicious breakfast snack or pack them for a quick on-the-go meal. Store refrigerated for up to 3 days and reheat gently in the air fryer or microwave.
