Air-Fryer Potato and Cheddar Frittata

Cooked potato, cheddar and chives turn into a browned, fluffy air-fryer frittata.

This recipe makes 4 servings and takes about 12 minutes to prepare plus 20 minutes to cook. Metric and imperial quantities are alternate measurements, so use one system rather than adding both. If you change the yield, keep the pan size and thickness of the food in mind: a crowded pan steams food and a deep baking dish can extend the cooking time.

Equipment

Set out air fryer, 18 cm ovenproof tin, mixing bowl. A wide pan gives moisture somewhere to evaporate; for an oven dish, leave space between pieces so heat can circulate. Use separate board and knife surfaces for raw protein and foods that will be eaten without further cooking.

Ingredients

You will need: cooked potatoes, diced: 400 g (14 oz); eggs, beaten: 6 large (6 large); mature cheddar, grated: 120 g (4 oz); spring onions, sliced: 60 g (2 oz); chives, chopped: 10 g (⅓ oz); olive oil: 10 ml (2 tsp); rocket leaves: 80 g (3 oz). Gather the ingredients before heating the pan so the aromatics do not burn while a measurement is being found.

• cooked potatoes, diced — 400 g / 14 oz
• eggs, beaten — 6 large / 6 large
• mature cheddar, grated — 120 g / 4 oz
• spring onions, sliced — 60 g / 2 oz
• chives, chopped — 10 g / ⅓ oz
• olive oil — 10 ml / 2 tsp
• rocket leaves — 80 g / 3 oz

Method

Read the full method once, then prepare the ingredients in the order listed. Keep raw and ready-to-eat ingredients separate, and wash hands and equipment after raw-protein contact.

Step 1

Brush the ovenproof tin with olive oil. Mix cooked potatoes, beaten eggs, three-quarters of the mature cheddar, spring onions and chives.

Step 2

Pour the mixture into the tin and scatter with the remaining mature cheddar.

Step 3

Air-fry at 170°C/340°F for 16 to 20 minutes until puffed, golden and set in the centre; a knife inserted in the middle should not show liquid egg.

Step 4

Rest for 4 minutes, cut into wedges, and serve with rocket leaves.

Cooking and safety check

Cook until the egg is completely set and no liquid egg remains at the centre. A time estimate and a browned surface do not prove that the centre is cooked. Use a suitable food thermometer where the ingredient or local guidance requires one, and follow the package or official instructions for the specific food.

Substitutions that respect the dish

A substitution should preserve the recipe’s job, not merely its colour. Use crumbled feta for cheddar; feta contains milk. Use baby spinach in place of rocket, folding it into the egg mixture. Use finely diced cooked sweet potato instead of white potato.

Allergen notes

This recipe contains or may contain milk, egg. Check every packaged ingredient because formulations and cross-contact warnings vary.

Common mistakes and how to correct them

Use one troubleshooting change at a time. If the centre is undercooked, return it to the appropriate heat and check again rather than relying on the outside colour. If the pan is dry, add liquid gradually; if it is watery, reduce uncovered. Texture may also reflect crowded equipment, a different ingredient size, or a changed batch quantity.

• Use a tin that allows air to circulate around it.
• If the top darkens too soon, cover loosely with foil.
• Dice potatoes evenly so they heat through at the same rate.

Leftovers and storage

Cool quickly, refrigerate for up to two days, and reheat wedges until hot throughout. Keep rocket leaves separate and serve fresh.

Frequently asked questions

Bake at 180°C/350°F for 25 to 30 minutes.

Can I use raw potato?

No; cook it first so the egg does not overcook while the potato softens.
