How do I keep this recipe from turning soggy?

Cook in a single layer, leave space for airflow, and avoid adding too much oil or sauce before the food has crisped.

Can I adjust the seasoning?

Yes. Keep the same cooking method and adjust salt, spice, herbs, citrus, or sauce to match your taste.

How do I know the eggs is done?

Use the visual cues in the instructions first: the outside should be browned or crisp and the center should be hot and tender. For meat or seafood, confirm doneness with a food thermometer.

1/4 cup milk (dairy or plant-based)
1 cup fresh spinach, chopped
1/3 cup crumbled feta cheese

Ingredients for Air Fryer Savory Spinach and Feta Breakfast Quiche Cups

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.
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.

Tips

Air Fryer Model Notes

Cook Air Fryer Savory Spinach and Feta Breakfast Quiche Cups in a single layer when possible. Basket models may need batches; oven-style models may need a tray rotation halfway through for even browning.

Crispiness Control

Pat the eggs dry, avoid crowding, and use only a light coat of oil or sauce before cooking. Add wet sauces near the end when you want the outside to stay crisp.

Doneness Cues

Look for browned edges, a hot center, and the texture described in the instructions.

Reheat In The Air Fryer

Reheat leftovers at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating.

Spinach: Substitute with kale, Swiss chard, or arugula for different flavors and textures.
Feta Cheese: Use plant-based cheese or nutritional yeast for dairy-free or vegan variations with umami richness.
Red Bell Pepper: Swap diced roasted red peppers, sun-dried tomatoes, or omit if preferred.

Seasonings: Try fresh herbs like thyme or basil, or add chili flakes for a spicy kick.

Storage

Store leftover Air Fryer Savory Spinach and Feta Breakfast Quiche Cups in an airtight container in the refrigerator for up to 3 days. Cool the food before sealing so excess steam does not soften the texture.
