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.

Ingredients

Servings6

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.
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.

Recipe guidance

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.

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.
