Leftover spiral-cut ham reheats at 320 °F (160 °C) for 4 minutes with no flip. The lower temperature is deliberate — the sugar glaze scorches to bitter-burnt above 340 °F, so ham needs a gentler setting than most reheats. Load straight from the fridge, brush each slice with 1 tsp reserved glaze or pan juices, and lay glaze-side up in a single layer. The internal target is 140 °F, not the 165 °F poultry standard; this ham was fully cooked at the plant and needs only warming through. The air fryer re-glosses the caramelised glaze and warms the centre at the same time — results the microwave and oven cannot match. Variant times at 320 °F: ¼-inch carved slice — 4 min / no flip; ½-inch dinner-cut slice — 5 min / no flip; diced ham — 3 min / shake at 1:30; 1-inch ham steak — 5 min / flip at 2:30.
Technique
Load straight from the fridge — no thaw, no preheat. Before placing in the basket, brush each piece with 1 tsp reserved glaze, pan juices, or honey mustard to restore surface moisture. Arrange glaze-side up in a single layer; glaze-side down transfers sugar directly to the grate and scorches within 30 seconds. Set 320 °F (160 °C) — lower than most reheats because the sugar glaze caramelises to bitter above 340 °F. No oil needed. Pull at 4 minutes and check with a probe. If slices have been sitting out and read above 130 °F before loading, tent loosely with foil for the first 2 minutes, then uncover for the final 2. Variant times, all at 320 °F: ¼-inch spiral-cut slice — 4 min, no flip; ½-inch dinner-cut slice — 5 min, no flip; diced or cubed ham — 3 min, shake at 1:30; 1-inch ham steak — 5 min, flip at 2:30.
Serving size: 4–8 oz per person in a single layer with ½-inch gaps. A 4-qt basket comfortably fits 4–6 oz; reheat larger quantities in 2–3 batches rather than stacking..
How to tell it’s done
The glaze surface is glossy and amber — not matte-dull (under-warmed) and not darkened or acrid-smelling (over-temp). A slice holds its shape with a gentle bend when lifted; flopping means under-warm, cracking means overdone. A probe at the thickest point reads 140 °F with no cold-pink core. Diced pieces are uniformly hot with no grey-cold clumps.
Watch out for
- Keep the temperature at 320 °F. The glaze sugars scorch to bitter-burnt within 60 seconds above 340 °F, and the lean meat dries to jerky within 90 seconds. If your air fryer runs hot, drop to 310 °F and add 60 seconds rather than risk scorching.
- Target 140 °F internally — not 165 °F (poultry standard) and not 145 °F (fresh pork). Leftover spiral-cut ham was fully cooked at the processing plant via wet-cure and smoke; this is a warming step, not a cook step. Overshooting to 165 °F dries the meat irreversibly.
- Brush 1 tsp of reserved glaze, pan juices, or honey mustard on the cut surface before loading. Refrigeration overnight draws moisture out of the surface, and skipping this step leaves a dry, matte slice. Plain water steams rather than glazes and is not a suitable substitute.
- Tent loosely with foil for the first 2 minutes if the slices read above 130 °F before loading — a sign they have been sitting at room temperature. Counter-warmed slices can overshoot the 140 °F target by the standard 4-minute mark; the tent slows centre warming during the first half so you hit 140 °F at the pull without overshooting.
FAQ about reheating leftover ham in an air fryer
- What temperature should I reheat a leftover ham at in an air fryer?
- Reheat a leftover ham at 320 °F (160 °C). The lower temperature is intentional — leftover food only needs to warm through, and higher heat would scorch the surface before the centre rewarms.
- How long does a leftover ham take to reheat in an air fryer?
- A leftover ham takes 4 minutes at 320 °F (160 °C) with no flipping. The convection air heats every surface evenly — a single layer is enough.
- Do you need to flip a leftover ham when reheating in an air fryer?
- No — leftover ham reheats evenly without a flip. The convection air reaches all sides simultaneously, and flipping a freshly heated leftover would disturb the surface as it crisps.
- Is the air fryer better than the microwave for reheating a leftover ham?
- Yes — the air fryer is dramatically better for any leftover that was originally crispy. A leftover ham reheated in a microwave goes soggy because microwaves steam the surface from the inside; the air fryer's convection heat drives off that surface moisture and restores the original crust. The downside is a slightly longer wait (4 min vs ~1 min in a microwave) — usually worth it.
- Can you reheat a leftover ham straight from the fridge?
- Yes — fridge-cold is the standard starting point and the timing on this page assumes it. There is no need to bring the food to room temperature first — the convection air handles the temperature differential well.
- Can you reheat multiple pieces at once in the air fryer?
- Yes, as long as they fit in a single layer with space between pieces. Stacked or overlapping pieces steam each other from their own moisture, which is exactly what you are trying to avoid when reheating crispy leftovers. Work in batches if your basket cannot hold the full serving in one layer.
- How is reheating a leftover ham different from cooking fresh ham steak?
- Reheating only needs to warm the food through and restore the crust — short total time, often a moderate temperature. Cooking fresh ham steak from raw takes 6 minutes at 350 °F (177 °C) and requires hitting an internal temperature of 145 °F at the thickest point — quite different parameters.

Cooking leftover ham from scratch?
Reheating is different from cooking — different temp, different time, different technique. Open the matching guide for the right numbers if you’re starting from a fresh or frozen state.
