Air fryers have revolutionised British kitchens, promising crispy chips and golden Yorkshire puddings without the guilt of deep frying. But not everything belongs in these magical countertop machines.
While they're brilliant for many foods, some ingredients can create kitchen disasters, damage your appliance, or simply turn out terribly disappointing.
1. Popcorn
Those unpopped kernels need temperatures higher than your air fryer can manage. They'll either sit there stubbornly unpopped or, worse, bounce around like tiny projectiles inside your machine.
The few that do pop might burn while you're waiting for the rest, leaving you with a disappointing snack and possibly a damaged appliance.
2. Leafy Greens (Like Spinach Or Kale)
A right royal mess awaits when you put loose leafy greens in an air fryer. The powerful fan sends them flying about like confetti at a village fête, creating an absolute shambles.
Your spinach or kale will either stick to the heating element or turn into dried-out, unappetising crispy bits. Stick to proper roasting or sautéing instead.
3. Raw Rice
Fancy a proper disaster? Try cooking raw rice in your air fryer! Unlike your trusty hob-top method, rice needs water absorption to cook properly.
The air fryer's hot, dry environment will leave you with hard, inedible grains that might even damage your machine. For perfect fluffy rice, the traditional saucepan method remains unbeaten in British kitchens.
4. Raw Pasta
Much like rice, pasta needs a proper bubbling pot of water to transform from rock-hard to al dente. Chuck it in the air fryer and you'll end up with oddly dried, possibly burnt, completely inedible pasta shapes.
No amount of sauce can rescue this culinary calamity. Stick to Nonna's traditional boiling method for pasta that would make any Italian grandmother proud.
5. Cheese (Without A Coating)
Ever seen a cheese explosion? Pop uncoated cheese in your air fryer and prepare for a spectacular mess. As it heats, the cheese melts rapidly, dripping through the basket and potentially causing smoke.
Before you know it, you'll have a gooey disaster that's harder to clean than last night's fondue pot. Breaded cheese works brilliantly, but naked cheese is asking for trouble.
6. Wet Battered Foods
Traditional British beer batter requires deep-frying to set properly. In an air fryer, wet batter will simply drip off your fish or chicken before it has a chance to crisp up.
The result? A soggy, disappointing mess at the bottom of your air fryer and naked food up top. Use panko or breadcrumbs instead for that proper crispy coating.
7. Whole Roasts (Large Cuts Of Meat)
A proper Sunday roast deserves better than being crammed into an air fryer. Large joints simply won't cook evenly, leaving you with overcooked edges and a worryingly pink middle.
The outside might burn while the inside remains dangerously undercooked. For your family's traditional Sunday lunch, the conventional oven remains king for good reason.
8. Fresh Broccoli
Raw broccoli in an air fryer ends up disappointingly dry and bitter—nothing like the vibrant, tender-crisp florets we love. The hot air quickly dehydrates these little green trees before they can properly cook through.
What should be a healthy side becomes an unappetising, woody mess. Blanching or steaming first can help, but honestly, why not just stick to those methods entirely?
9. Saucy Dishes (With Too Much Liquid)
Attempting to cook your mum's famous curry or a proper British stew in an air fryer? Think again! Excessive liquid creates a bubbling cauldron that can spill over, causing smoke and potentially damaging your machine.
The sauce won't reduce properly, and you'll miss out on that lovely slow-cooked flavour. Keep your air fryer for crispy bits, not saucy favourites.
10. Loose Seasonings Or Herbs
Sprinkling dried herbs or spices directly into your air fryer is like throwing confetti into a fan. Your carefully measured herbs will swirl around, stick to the heating element, or simply blow away entirely.
This not only wastes your posh spices but can create smoke or even fire hazards. Always mix seasonings directly into your food or with a bit of oil first.
11. Fried Dough (Without Modification)
Fancy a proper doughnut? The air fryer won't deliver that classic fairground treat you're craving. Traditional fried dough needs to float in hot oil to achieve that distinctive texture and even cooking.
Air-fried doughnuts often end up oddly shaped, dense, and nothing like the light, fluffy treats from your local bakery. Some recipes can be modified, but purists will always prefer the traditional method.
12. Toast With Toppings
Attempting beans on toast or cheese on toast in your air fryer? You're asking for trouble, mate! The circulating air sends lightweight toppings flying about, creating an absolute shambles inside your machine.
Melted cheese drips through the basket, while beans create a burnt, crusty mess. The grill function on your trusty oven remains the champion for these British classics.
13. Buttered Bread
Slathering bread with butter before air frying creates a greasy nightmare. The butter melts instantly, dripping through the basket and potentially smoking at high temperatures.
Your bread ends up unevenly toasted - soggy in some spots, overly dry in others. For proper toast, the humble toaster remains undefeated in British kitchens for good reason.
14. Bacon
A proper British breakfast deserves properly cooked bacon. Air fryers can cause excessive smoke as the fat renders out, potentially setting off your smoke alarm and waking the entire household.
The rashers often curl up oddly, cooking unevenly and sometimes sticking to the basket. For that perfect crispy-yet-tender bacon, the trusty frying pan remains supreme.
15. Hamburgers (If Very Fatty)
High-fat burgers create a proper smoky situation in air fryers. As the fat renders out, it can splatter onto the heating element, causing excessive smoke that might have your neighbors thinking your kitchen's on fire.
The rendered fat also makes cleaning a nightmare. Leaner burgers work better, but for that classic juicy burger, the grill or pan remains king.
16. Cakes Or Batters (In Open Baskets)
Victoria sponge catastrophe! Pouring cake batter directly into an air fryer basket is asking for a spectacular mess. The batter seeps through the holes before it can set, creating a goopy disaster below.
What little remains in the basket cooks unevenly and dries out quickly. Always use proper baking tins designed for air fryers if you're determined to bake in them.
17. Steamed Veggies (Like Courgettes Or Aubergines)
Vegetables with high moisture content like courgettes turn tragically disappointing in air fryers. Instead of becoming properly tender, they often dry out on the outside while remaining oddly raw inside.
The texture becomes weirdly leathery rather than pleasantly soft. For proper treatment of these Mediterranean favourites, steaming or sautéing remains the superior choice in any British kitchen.
18. Hard-Boiled Eggs
Attempting hard-boiled eggs in an air fryer? Prepare for a potential eggy explosion! The rapidly heating air causes pressure to build inside the shell, sometimes resulting in a proper mess and an almighty bang.
Even if they don't explode, they often cook unevenly. The traditional pan of boiling water remains foolproof for your morning egg and soldiers.
19. Nuts
Toasting nuts requires careful attention to prevent burning. Air fryers heat so intensely and unevenly that your expensive pine nuts or walnuts can go from raw to burnt in seconds.
The smaller nuts might fall through the basket holes or get blown about by the fan. For perfectly toasted nuts for your salads or baking, a dry frying pan gives you the control you need.
20. Foods With High Water Content
Fresh fruits and veg with high water content turn surprisingly disappointing in air fryers. Cucumber, watermelon, and similar water-rich foods end up as sad, shriveled versions of their former selves - neither raw and refreshing nor properly cooked.
The intense heat simply evaporates the moisture, leaving you with unappetizing, dehydrated remnants. Some things are best enjoyed in their natural state!
