A deep fryer submerges food fully in hot oil for that classic crispy, restaurant-style texture, while an air fryer circulates hot air with little to no oil. Deep fryers are best if you want authentic fried results - think chip shop chips or proper battered fish - whereas air fryers are a lower-fat alternative.

For 1-2 people, a 1.5L deep fryer is usually enough. For a family of 3-4, a 3L deep fryer gives more capacity without taking up too much worktop space. If you regularly cook for larger groups or want to fry multiple foods at once, a 5L double basket deep fryer lets you cook separate items - like chips and onion rings - at the same time.

Yes, most electric deep fryers allow you to store filtered oil in the fryer between uses, provided the lid is closed and it's kept somewhere cool. For best results and flavor, we recommend changing the oil every 8-10 uses, or sooner if it looks dark or smells off.

Most electric deep fryers reach frying temperatures within 5-10 minutes, depending on wattage and oil volume. Our 2000W models heat faster, which is ideal if you're frying in batches.

A viewing window lets you monitor your food as it cooks without opening the lid, which helps retain heat, reduces oil splatter, and stops the frying temperature from dropping - so you get more consistent, crispier results.
