Doneness
Cheese top is fully melted and starting to brown in spots; sauce is bubbling visibly at the edges; centre is hot when probed with a fork — the noodles should still flex slightly without crumbling.
Technique
Transfer the slice to a small oven-safe dish (ceramic or foil pan). Cover tightly with foil for the first 5 minutes — this traps steam so the centre warms through without the noodles drying into shards. At the 5-minute mark, peel the foil off entirely (use tongs; the foil is hot) and cook the final 3 minutes uncovered so the cheese top browns and crisps the way it does in an oven. This two-stage covered-then-uncovered approach is the entire reason this reheat is better than the microwave's all-steam-no-crisp result.
Watch out for
- Do not skip the foil-cover first half. Without it, the noodles around the edges go cracker-crunchy before the centre warms — the single most common failure mode on this reheat.
- Single layer only. Lasagna slices stacked on top of each other never warm through evenly; the bottom slice burns while the top stays cold.
- Skip the air fryer for very wet lasagna (sauce running off the slice) — transfer that to a baking dish in the oven instead. The air fryer's open-grate basket lets too much liquid drip down.
