Air Fryer Potato Frittata (Spanish Tortilla Style)

A fluffy air fryer potato frittata inspired by the classic Spanish tortilla — tender potatoes and sweet onion set in eggs with a little Parmesan. The air fryer sets it evenly into a golden, sliceable round.
It's a satisfying breakfast, brunch or light dinner that's great warm or at room temperature. Serve it in wedges, tapas-style.
Ingredients
Instructions
Soften the potatoes
Sauté the sliced onion in a little oil, add the potatoes, cover and cook until tender (or air fry at 380°F for 12 minutes). Season.
Combine
Beat the eggs with the Parmesan, garlic powder, parsley, salt and pepper. Stir in the potato-onion mixture.
Air fry
Pour into a greased pan that fits your basket and air fry at 350°F for about 15–18 minutes, until set and golden on top.
- Cook the potatoes until fully tender before adding the eggs.
- Use a pan that fits with airflow around it.
- Let it rest a few minutes so it slices cleanly.
Frequently asked
How long does a frittata take in the air fryer?
About 15–18 minutes at 350°F in a pan, until set and golden.
What's the difference between a frittata and a Spanish tortilla?
Both are egg-and-potato based; a tortilla is flipped on the stovetop, while this version bakes in the air fryer for ease.
Can I add other fillings?
Yes — peppers, chorizo, spinach or cheese all work well.
