How long do I air-fry a gammon joint?
General rule for cooking time per weight
- The widely repeated formula is 25 minutes per 500g of raw gammon plus an extra 20 minutes.
- For a typical UK 750g joint that works out at roughly 25 × 1.5 + 20 = 57.5 minutes. Most recipes round to 50–60 minutes.
- Curly’s Cooking (UK food blog) uses 70 minutes at 170°C for a 1.5kg joint, then 5 minutes after glazing (Curly’s Cooking).
Air fryer temperature settings for gammon
- Preheat to 160–170°C (Beat The Budget recommends 170°C; Supergolden Bakes also preheats at 170°C).
- Higher wattage air fryers (1800W+) can shave 5–10 minutes off the total time.
The implication: you can reliably plan your cooking around this formula regardless of your air fryer brand, adjusting only for wattage differences.
How do I keep gammon moist in the air fryer?
Using foil to retain moisture
- Wrap the gammon tightly in foil for the first part of cooking. Taming Twins (family recipe blog) cooks a foil parcel at 160°C for 30 minutes, turns it, reseals, and cooks another 30 minutes (Taming Twins).
- Beat The Budget keeps the foil on for 35 minutes at 170°C before unwrapping for glazing.
Basting and glazing techniques
- Brush glaze every 20 minutes during the uncovered stage (BBC Good Food advises brushing more glaze every 20 minutes).
- Feast Glorious Feast (UK recipe site) applies glaze in two separate 10‑minute stages at 190°C for a sticky finish (Feast Glorious Feast).
Foil traps steam that keeps the ham tender. Skipping the foil stage means you get a dry exterior before the inside is done. The trade‑off: foil slows browning, so you must uncover for the final glaze blast.
The catch: you trade moisture protection for browning speed, which is why the two-stage method is non-negotiable for air fryer gammon.
Can you cook gammon in foil in an air fryer?
Safety of aluminum foil in air fryer
- Aluminum foil is safe as long as it does not touch the heating element or block air circulation (UK Food Standards Agency stresses that air must circulate for proper cooking (UK Food Standards Agency)).
- Never cover the entire basket base — leave gaps for airflow.
How to wrap gammon in foil
- Place the joint in the centre of a large foil sheet, bring the sides up and seal loosely, leaving a small air gap.
- Supergolden Bakes wraps the gammon fully in foil, then cooks at 170°C for the first 30 minutes per 500g before unwrapping for glazing (Supergolden Bakes).
The pattern: foil‑wrap first, glaze second. That two‑stage approach is the most effective way to combine moisture retention with a caramelised crust.
Is gammon better in the oven or air fryer?
Three differences that matter if you’re choosing between methods:
| Aspect | Air Fryer | Oven |
|---|---|---|
| Total cooking time (750g joint) | 50–60 minutes | 1.5–2 hours |
| Texture | Crispier exterior, drier risk if not foiled | More even heat, less crust |
| Energy use | ~1400–1800W vs oven ~2500W; shorter preheat | Higher overall consumption |
- The air fryer cooks faster (approx 45–60 min vs 1.5–2 hours in oven, as confirmed by multiple UK recipe sources including Feast Glorious Feast).
- The oven’s even heat gives more forgiving moisture distribution; the air fryer demands foil and glazing discipline.
The implication: your choice depends on whether speed and crust matter more than hands-off convenience.
What are the common mistakes when roasting gammon?
Overcooking and dryness
- Not using a meat thermometer leads to overcooking (Supergolden Bakes recommends 62°C internal, resting to 71°C).
- Skipping the foil wrap is the fastest route to a dry, tough joint.
Skipping the glaze
- Failing to glaze leaves the surface pale and less flavourful.
- A good glaze — like Feast Glorious Feast’s brown sugar, wholegrain mustard, Dijon, and sea salt — adds both shine and moisture protection.
Foil and glaze are a balancing act: too much foil and the glaze never browns; too little and the meat dries. The golden rule is 30 minutes foil‑wrapped, then glaze every 20 minutes while uncovered.
The pattern: every mistake traces back to either under-protecting or over-protecting the meat, which the foil-glaze sequence solves.
How to Cook a Gammon Joint in the Air Fryer: Step-by-Step
- Prepare the gammon: If the joint has a thick rind, score the fat in a diamond pattern. Pat dry with kitchen paper.
- Preheat the air fryer: Set to 170°C for 5 minutes.
- Wrap in foil: Place the gammon in the centre of a sheet of foil, bring the sides up and seal loosely. Leave a small air gap inside the parcel.
- First cook (foil‑wrapped): Cook at 170°C for 35 minutes (750g) to 40 minutes (1kg). For larger joints, use 25 min per 500g plus 20 min.
- Prepare the glaze: Mix honey, wholegrain mustard, and a pinch of cloves (or use Taming Twins’ marmalade‑honey glaze).
- Glaze and second cook: Remove foil, brush glaze all over, then return to air fryer at 180–200°C for 10–15 minutes. Brush with more glaze every 5 minutes (BBC Good Food).
- Rest and carve: Let the gammon rest for 15–20 minutes (Curly’s Cooking). Check internal temperature — target 63°C, which will rise to 71°C while resting.
The implication: this sequence gives you a repeatable method where the foil phase guarantees moisture and the glaze phase guarantees crust.
Confirmed facts
- Cooking time rule: 25 min per 500g + 20 min is widely cited across multiple recipe sources.
- Preheating the air fryer improves results (Supergolden Bakes).
What’s unclear
- Exact impact of air fryer brand on cook time (e.g., Ninja vs Philips) — recipe times vary.
- Whether soaking or brining gammon before air frying is beneficial — no consistent guidance.
What the recipe writers say
“Heat the air-fryer to 160C. Put the gammon in the air-fryer and cook for 1 hr, brushing with more glaze every 20 mins if you can.”
— BBC Good Food recipe author (BBC Good Food)
“The general rule is to cook for 25 minutes per 500g (raw) meat, plus an extra 20 minutes.”
— The Gluten Free Blogger
For UK cooks short on time, the air fryer gammon method delivers a juicy, glazed joint in under an hour — a real alternative to the traditional roast, as long as you don’t skip the foil or the resting time. The trade‑off is clear: you trade 30 minutes of baking for 10 minutes of hands‑on glazing. For the best results, invest in a meat thermometer and stick to a 750g–1kg joint to match your basket size.

Frequently asked questions
Can I cook a gammon joint without foil in the air fryer?
Yes, but the risk of drying out is much higher. Foil traps steam and keeps the ham tender. If you skip it, reduce the temperature to 160°C and baste every 10 minutes.
How do I make a honey glaze for gammon in the air fryer?
Mix 2 tablespoons honey, 1 tablespoon wholegrain mustard, and a pinch of ground cloves. Brush on after the first foil‑wrapped stage and re‑apply every 5–10 minutes.
Do I need to preheat the air fryer for gammon?
Yes — preheat for 5 minutes at 170°C. This ensures the cooking time is accurate from the start.
Can I cook a frozen gammon joint in the air fryer?
It’s not recommended. The outside will cook and dry out before the centre is done. Always thaw completely before cooking.
What is the best size gammon for an air fryer?
750g–1kg fits most standard air fryer baskets. Larger joints (1.5kg+) may need to be cut in half or cooked in an oven.
How do I reheat leftover air fryer gammon?
Slice cold gammon and reheat in the air fryer at 160°C for 3–4 minutes. Brush lightly with oil or leftover glaze to prevent drying.
Is it necessary to rest gammon after air frying?
Yes — rest for 15–20 minutes. The internal temperature will continue to rise and the juices redistribute, giving a more tender result.
