Air Fryer Jacket Potatoes: Crisp Skin, Fluffy Inside, Bonfire Night

Print recipe

Ingredients (serves 4 servings)

• 4 medium baking potatoes, about 8 oz (225g) each
• 1 tablespoon olive oil
• 1 teaspoon coarse salt
• Toppings: butter, grated cheese, baked beans, tuna mayonnaise, coleslaw, or chilli con carne
• Optional: sour cream, chives, or roasted vegetables

Method, step by step

1. Choose even potatoes. Choose baking potatoes of similar size, about 8 oz each, with unblemished skin. Even potatoes finish at the same time; a mix of sizes means some are hard while others are overcooked.
2. Wash and dry. Wash the potatoes well and dry them thoroughly. Wet skin steams instead of crisping, so drying matters even for a long cook.
3. Prick, oil and salt. Prick each potato all over with a fork, about 8–10 times, so steam can escape. Rub with oil, then sprinkle with coarse salt, coating the skin evenly.
4. Preheat. Preheat the air fryer to 400°F / 200°C for 3 minutes. A hot start helps the skin crisp from the beginning, rather than softening first.
5. Cook long. Place the potatoes in the basket with space between them, and cook for 45–60 minutes, turning once halfway, until the skin is crisp and the potato gives slightly when squeezed with an oven glove.
6. Check the inside. Check by inserting a fork or skewer into the centre — it should go in easily, with no hard resistance. If it meets resistance, cook for another 10 minutes and check again.
7. Rest, split and fluff. Rest for 5 minutes, then split each potato open with a knife, squeeze the ends gently to open it up, and fluff the inside with a fork before adding butter and toppings.

Jacket potatoes time by size

Size matters more than anything else for jacket potatoes — a large potato can need 20 minutes more than a medium one.

Choosing the main ingredient

Choose baking potatoes, not waxy potatoes — varieties sold as baking, russet, or King Edward are best, as they have a dry, fluffy texture when cooked. Waxy potatoes, like new potatoes, stay dense and waxy inside, even after a long cook, and they will not give the fluffy centre that makes a jacket potato. Choose potatoes of similar size, with firm, unblemished skin and no green patches or sprouts. Green patches should be cut away, and sprouted potatoes should be avoided, as they can taste bitter.

The difficult part — and why it fails

The difficult part of jacket potatoes is the skin-versus-inside balance — getting a skin that is crisp and crackling without drying out the inside, and an inside that is fluffy, not dense or hard. It fails when the potato is cooked too fast, or wrapped in foil, or not oiled and salted. Foil, which many people use out of habit, steams the skin and makes it soft, which is the opposite of a jacket potato. Cooking at a lower temperature for a shorter time leaves the skin pale and the centre hard. The fix is a long, hot, uncovered cook: 400°F / 200°C for 45–60 minutes, with oil and salt on the skin, turning once, and checking with a skewer, not by squeezing alone.

5 mistakes to avoid

1. Wrapping in foil. Foil steams the skin and makes it soft. Cook uncovered for a crisp jacket.
2. Using waxy potatoes. Waxy potatoes stay dense inside. Use baking potatoes, russet, or King Edward.
3. Skipping oil and salt. Oil and salt are what crisp the skin. Without them, the skin stays pale and soft.
4. Cooking too short. Jacket potatoes need 45–60 minutes. A hard centre means more time, not more heat.
5. Not pricking. Unpricked potatoes can burst as steam builds up. Prick 8–10 times all over.

Easy variations

• Cheese and beans: The classic: butter, baked beans, and grated cheese, with the cheese melting into the beans.
• Tuna mayonnaise: Tuna mixed with mayonnaise and sweetcorn, with a squeeze of lemon and black pepper.
• Chilli con carne: Chilli spooned over butter, with grated cheese and sour cream on top.
• Roasted vegetables: Roasted peppers, mushrooms, and courgette, with a herb dressing, for a lighter topping.
• Coleslaw and cheese: Coleslaw and grated cheese, with chives, for a cool, crunchy contrast to the hot potato.
• Sour cream and chives: Butter, sour cream, and chopped chives — simple, and the best way to taste the potato itself.

What to serve with it

Jacket potatoes are a Bonfire Night and winter staple, served hot, split open, with butter first — butter melts into the fluffy inside and carries every other topping — then the topping of choice. They work as a main with a salad, or as a filling supper on their own, and they are easy to serve for a crowd: cook them in batches, keep the finished ones warm in a low oven, uncovered, and let guests choose their own toppings. For Bonfire Night, they are traditionally eaten outdoors, wrapped in foil only after cooking, not during, so the skin stays crisp until the last moment.

Storage and reheating

Jacket potatoes are best eaten fresh, within 15 minutes of cooking, while the skin is still crisp. If you must keep them, cool them on a rack, store in the fridge for up to 3 days, and reheat at 400°F / 200°C for 10–12 minutes until hot through and the skin crisps again. Do not store cooked potatoes in foil while warm — trapped steam softens the skin. Uncooked potatoes keep for weeks in a cool, dark place, so there is rarely a reason to cook them far ahead.

Why this recipe works

This method works because it gives the potato what it needs: time, heat, and a dry, uncovered skin. At 400°F / 200°C, hot air crisps the oiled, salted skin steadily, while the long cook lets heat reach the centre and turn the starch fluffy. Pricking lets steam escape, so the potato does not burst and the skin does not go soggy from trapped steam.

Ingredient notes and swaps

Potato size is the biggest variable: a 6 oz potato and a 12 oz potato can be 20 minutes apart, so always check with a skewer, not by time alone. If you are short on time, microwave the potatoes for 5 minutes first, then air fry for 40 minutes — the skin will still crisp, though it will be slightly less crackling than a full air fryer cook. Oil choice matters less than amount: olive oil, vegetable oil, or rapeseed oil all work, as long as the skin is evenly coated. Coarse salt gives a better crunch than fine salt, which can dissolve into the oil and disappear.

Equipment and which fryer size works best

You need an air fryer, a fork for pricking, a knife, and an oven glove for handling hot potatoes. A 5–6 qt basket fits 2–4 medium potatoes at a time, depending on size, so a family batch usually needs two rounds. A dual basket helps if you are cooking potatoes and a topping, like roasted vegetables, at the same time.
