You don’t strictly need oil for an air fryer, as it cooks food by circulating hot air around it. However, a light coating of oil can improve crispiness and browning for certain foods. Many recipes at airfryerrecipe.co.uk/recipes show how to adapt dishes with minimal or no oil.
Air fryers use rapid air technology to crisp food without submerging it in oil like traditional deep fryers. The heating element and fan circulate hot air at high speeds, creating a similar effect to frying. This means you can cook foods like chicken wings or chips with just a fraction of the oil. For oil-free options, check out our vegetable recipes that rely on natural moisture.
Some foods release enough natural fats during cooking, eliminating the need for added oil. Items like salmon or sausages often cook perfectly without extra grease. If you’re avoiding oil altogether, parchment liners or a light water spray can prevent sticking. The team at airfryerrecipe.co.uk recommends experimenting to find your preferred balance.
A small amount of oil enhances texture for foods that don’t contain natural fats. Vegetables like Brussels sprouts or potatoes benefit from a light misting to achieve that golden crunch. Use an oil sprayer for even coverage—about 1-2 teaspoons max for most recipes. Our conversion chart helps adjust traditional recipes for air frying with less oil.
High-smoke-point oils like avocado or rapeseed work best for air fryer temperatures. Avoid aerosol sprays with additives, which can damage the basket’s non-stick coating over time. For crispy tofu or breaded items, a thin oil layer helps bind coatings and improve browning. Many users find that oil isn’t needed daily but is handy for occasional indulgent dishes.
Marinades and spice rubs add flavour without oil—try lemon juice, vinegar, or yogurt-based coatings. Foods with high water content, like mushrooms or zucchini, crisp up nicely when patted dry before cooking. Preheating your air fryer ensures immediate crisping, reducing the need for oil.

Some believe air fryers require as much oil as deep frying, but this isn’t true—most recipes use 90% less. Another myth is that oil-free cooking always means dry food; proper timing and temperature prevent this. Regular cleaning with airfryer cleaner maintains performance whether you use oil or not.
Certain foods, like frozen chips or pre-breaded items, already contain oil and don’t need extra. Testing small batches helps determine if your preferred dish needs oil at all. Remember, air fryers are versatile—you can choose oil-free most days and add a touch for special occasions.
Light olive oil and coconut oil add subtle flavours without overpowering dishes. For neutral taste, refined sunflower or grapeseed oil works well in high heat. Always apply oils sparingly with a brush or spray bottle to avoid pooling. Even with oil, air fryers use far less than conventional methods, keeping meals healthier.
