Ingredients

Servings 6
  • 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

  1. Preheat your air fryer to 320°F (160°C).
  2. In a medium bowl, whisk together the eggs and milk until smooth and slightly frothy.
  3. Stir in the chopped spinach, crumbled feta, red bell pepper, green onions, dried oregano, garlic powder, salt, and pepper until evenly combined.
  4. Lightly grease six silicone or metal muffin cups or ramekins with non-stick cooking spray or olive oil.
  5. Divide the egg mixture evenly among the prepared cups, filling each about three-quarters full to allow room for rising.
  6. Carefully place the filled cups into the air fryer basket or tray, spacing them to allow even air circulation.
  7. 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.
  8. Remove the cups carefully using tongs or a spoon and allow them to cool for a minute or two before removing from the cups.
  9. 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.

Air Fryer Model Notes

This recipe for Savory Spinach and Feta Breakfast Quiche Cups works well across most common air fryer models, but slight differences in size, basket shape, and heating elements can influence cooking time and texture.

Size and Capacity: Compact air fryer baskets may only fit a few muffin cups at once, requiring multiple batches. Larger or multi-tiered air fryers can cook all six cups simultaneously. Leave space between cups for optimal air circulation.

Heating Elements: Models with strong top heating elements and fans deliver the best crispness and browning on top. If your air fryer has indirect or mild heat, cook for 1–2 minutes longer to ensure the eggs are fully set and slightly golden.

Temperature Control: Precise temperature control at 320°F (160°C) yields fluffy custard without drying. Some air fryers run hotter or cooler, so check the quiches a few minutes before minimum time.

Cookware Compatibility: Both metal and silicone muffin cups or ramekins work well. If your basket is non-stick coated, lightly grease cups and basket to prevent sticking and ease removal.

Adjust cooking times and spacing according to your air fryer characteristics for consistently fluffy, golden quiche cups. These tips help you enjoy a reliable, delicious, and easy air fryer breakfast treat.

Crispiness Control

For the ideal texture in these Air Fryer Savory Spinach and Feta Breakfast Quiche Cups, balance a tender, fluffy interior with a gently crisped top. As a Snack and vegetarian, healthy, and snackable dish, the crispness should enhance rather than overwhelm.

To boost crispiness: Air fry at 320°F (160°C) for a full 15 minutes or up to 2 minutes longer focusing on the tops. Lightly brush olive oil on top before cooking to encourage browning. Using metal ramekins instead of silicone results in crisper edges.

For a softer, custard-like texture: Reduce cooking time to around 12 minutes and avoid extra oil. Loosely cover cups with foil while air frying to retain moisture and soften the tops.

Pro Tip: The gentle crispness complements the creamy spinach and feta filling without drying out the eggs. Maintaining 320°F balances cook-through and light browning—avoid higher temperatures to prevent toughness or dryness.

Adjust cooking duration and oil application to your texture preference for a perfect bite every time.

Reheat In The Air Fryer

Reheat your Air Fryer Savory Spinach and Feta Breakfast Quiche Cups in the air fryer to keep their crisp edges and fluffy interior.

  1. Preheat the air fryer to 320°F (160°C) for gentle, even warming.
  2. Arrange quiche cups spaced evenly in the basket for good air flow.
  3. Heat for 3–5 minutes, checking midway to avoid overcooking. Refrigerated cups need about 3–5 minutes; frozen cups (preferably thawed) take 7–8 minutes.
  4. Check that cups are warmed through with crisp edges but moist centers.
  5. Remove carefully and allow to cool briefly before eating.

Tips: Avoid increasing temperature to protect a tender egg texture and soft feta. For softer reheated quiches, loosely cover with foil. Enjoy moist, flavorful quiche cups that are quick to reheat and perfect for busy mornings or snacks.
