Reheat Calzone in an Air Fryer

Doneness

The crust is golden amber on most of the surface, with a light crisp shell. The filling is fully warm and the calzone smells like a fresh-from-the-oven pizza. No cheese should be leaking from the side seam — the top slit handles steam release cleanly. A thicker-shell handmade calzone may need 1–2 extra minutes; a thinner homemade-dough version may be done in 7 minutes.

Technique

Cut a 2–3-inch slit straight across the top of the calzone before loading — this vents the steam pocket inside and prevents a blowout at the seam. Place the calzone seam-side down in the basket. Do not preheat. Loosely tent it with aluminium foil (not a tight wrap — air needs to circulate around it) and cook at 325 °F (163 °C). At the 4-minute mark, slide the basket out, flip the calzone with two spatulas (not tongs, which can tear the edge), re-tent loosely, and return to the fryer. At the 5-minute mark, carefully remove the foil tent with tongs — the foil will be hot. Let it cook uncovered for the final 3 minutes to crisp and colour the crust. Serve with reserved marinara in a small ramekin on the side.

Watch out for

• !Use 325 °F, not 400 °F. The calzone's thick double-crust needs time for heat to reach the filling; 400 °F scorches the outer crust in about 4 minutes before the cheese and ricotta inside are even warm.
• !Cut a vent slit across the top before cooking. The sealed interior traps steam as the filling heats; without a vent, pressure blows out the side seam and the filling leaks into the basket.
• !Tent with foil for the first 5 minutes, then uncover. Skipping the tent lets the outer crust scorch before the filling reaches 165 °F. Use a loose tent — tight wrapping blocks the convection airflow that makes the crust crisp in the final uncovered minutes.
• !Cook one calzone at a time in a single layer. Stacked calzones block airflow and reheat unevenly — the outer one scorches while the inner one stays cold. For two calzones, run two sequential 8-minute batches; keep the first warm in a 200 °F oven on a rack.
• !Add marinara after pulling, never in the basket. Tomato sauce at 325 °F scorches within 4 minutes, pools under the calzone, and makes cleanup difficult. Serve it in a small dipping ramekin alongside.
