Air Fryer Spinach Feta Frittata

Air Fryer Spinach Feta Frittata

I rely on the visual cue more than the clock with an air fryer frittata because eggs can set fast around the edges while the center still needs a few more minutes. The part I pay attention to most is moisture: spinach needs to be very well drained, and if the top starts browning too early, a loose piece of foil helps the middle catch up.

This version keeps things simple with eggs, milk, spinach, cherry tomatoes, and feta. It fits neatly in a small pan, works for breakfast, brunch, or a light dinner, and leftovers reheat well when you warm them gently.

Ingredients for Air Fryer Spinach Feta Frittata

• 6 large eggs (about 300g)
• 1/4 cup milk (60g)
• 1/2 teaspoon fine sea salt
• 1/4 teaspoon fine ground black pepper
• 1 cup spinach (30g), thawed if frozen and squeezed very dry
• 1/2 cup cherry tomatoes (75g), halved
• 1/2 cup feta cheese (75g), crumbled
• 1 teaspoon olive oil, or enough nonstick spray to lightly coat the pan

Ingredient note: Fine sea salt and finely ground black pepper work well here because they season the egg mixture evenly without leaving concentrated salty or peppery spots. If you need them, the linked spices from Selefina fit that style well.

If you want a lighter version, you can replace some of the whole eggs with egg whites. I find this works best in a shallow pan, since egg-white-heavy mixtures turn firm faster and can lose tenderness if you leave them in too long.

Optional add-ins that work well here include 1/2 cup cooked diced ham, 1/2 cup sautéed mushrooms, 2 tablespoons chopped green onions, or a pinch to 1/4 teaspoon red pepper flakes. Keep any watery vegetables cooked or drained first so the center does not stay soggy.

Best Pan Size for an Air Fryer Frittata

Use a small oven-safe pan or baking dish that fits inside your air fryer with a little room around it for airflow. A shallow pan cooks more evenly than a deep dish, which matters with eggs.

Grease the pan well, and if you want easier removal, line the bottom with greased parchment that fits flat. Do not overfill the pan; a moderately shallow layer helps the center set before the top gets too dark.

How to Make Spinach Feta Frittata in the Air Fryer

1. Preheat the air fryer: Preheat to 320°F to 350°F (160°C to 175°C). Preheating helps the eggs start setting more evenly, especially if your air fryer runs hot or cooks unevenly.
2. Prep the spinach and pan: If using frozen spinach, thaw it completely and squeeze out as much liquid as possible. It should feel dry, not wet. Lightly grease a small air fryer-safe pan or dish with olive oil or nonstick spray.
3. Mix the eggs: In a bowl, whisk together the eggs, milk, salt, and black pepper until fully combined. Stir in the spinach, cherry tomatoes, and feta. If you are adding ham or mushrooms, make sure they are cooked and not carrying excess moisture.
4. Fill the pan: Pour the mixture into the prepared pan and spread the spinach, tomatoes, and feta around so they are evenly distributed. Keep the surface level for more even cooking.
5. Air fry: Place the pan in the air fryer with a little space around it for airflow. Cook at 320°F to 350°F (160°C to 175°C) for 12 to 18 minutes. There is no flipping or shaking. If the top starts browning too quickly before the center is nearly set, loosely cover the pan with foil.
6. Check for doneness: Start checking at the low end of the range, especially if you are using a dark pan, a deeper dish, or a powerful basket-style air fryer. The frittata is done when the edges are set, the center has only a slight wobble, and a knife inserted near the middle comes out mostly clean. If you are using a thermometer, look for 160°F to 165°F (71°C to 74°C) in the center.
7. Rest and slice: Let it rest for 3 to 5 minutes before lifting or slicing. It will firm up a little as it stands, which makes cleaner wedges.

Air Fryer Time and Temperature for Frittata

For this size frittata, use 320°F to 350°F (160°C to 175°C) for 12 to 18 minutes. Start checking early rather than assuming your air fryer will match someone else’s timing.

I usually look for set edges and a center that still jiggles just slightly. If the top is getting darker before the middle is close, cover loosely with foil and finish cooking until the center is just set.

How to Keep an Air Fryer Frittata from Getting Watery

This is where the texture can go wrong. Spinach and tomatoes both bring moisture, and the air fryer can brown the top before the center has fully set.

• Squeeze thawed spinach very dry before adding it.
• Use a moderate amount of tomatoes instead of packing in extra.
• Cook mushrooms, zucchini, onions, or other watery vegetables before mixing them in.
• Use a shallow pan so the center sets more cleanly.

Easy Variations

Lighter Egg-White Version

Replace some of the whole eggs with egg whites if you want a lighter frittata. The texture will be a bit less rich, and it can turn firm faster, so start checking early.

Ham and Spinach Frittata

Add 1/2 cup cooked diced ham for a heartier version. Keep the amount moderate so the egg mixture still sets well and slices cleanly.

Mushroom Spinach Frittata

Add 1/2 cup sautéed mushrooms, either in place of some of the tomatoes or alongside the spinach. Let their moisture cook off before adding them to the eggs.

What to Serve with Spinach Feta Frittata

Serve it warm with hot sauce if you want a little heat. It also works well with roasted baby potatoes, toast, fresh fruit, or a simple green salad.

How to Store and Reheat Spinach Feta Frittata

Let leftovers cool completely, then refrigerate them in an airtight container for up to 3 to 4 days. The texture will firm up a little after chilling, which is normal for egg dishes.

To reheat, warm slices gently in the air fryer at a lower temperature until heated through instead of blasting them at high heat. Thin slices reheat quickly, so watch closely and pull them out as soon as they are warm. If the top is browning too much, cover loosely with foil.
