Many calzone enthusiasts unwittingly compromise their leftovers by reaching for the microwave, a convenient yet destructive reheating method that transforms crispy crusts into disappointing rubber. The rapid heating creates trapped steam, which breaks down the carefully developed gluten structure that gives properly cooked dough its satisfying bite. While microwaving takes mere minutes, the textural sacrifice hardly justifies the time saved. Fortunately, alternative approaches exist that preserve both flavor integrity and the contrasting textures that make calzones so appealing in the initial place.
The Microwave Mistake: Superior Reheating Methods Revealed

Transforming day-old calzones back to their original glory requires understanding the delicate balance between crispness and moisture. Many calzone enthusiasts make the critical mistake of defaulting to microwave reheating, which might seem convenient but ultimately yields a disappointing experience—a soggy, rubbery crust that bears little resemblance to its former crispy self.
This common approach fundamentally ruins the textural integrity that makes calzones so satisfying in the beginning. The microwave’s rapid heating creates steam that gets trapped within the calzone, resulting in a gummy interior and an exterior that lacks any pleasant resistance when bitten. The dough’s gluten structure becomes compromised when microwaved, destroying the carefully developed elasticity achieved during preparation. Much like homemade pizza dough, calzones require active dry yeast to achieve the perfect texture and rise.
Microwaving destroys everything that makes a calzone worth eating—leaving nothing but a sad, steamy shell of its former self.
For truly impressive results, conventional ovens remain the gold standard. Preheating to 375°F guarantees the calzone reheats gradually and evenly, allowing the crust to crisp while the filling warms without becoming molten or dried out. Room temperature calzones should sit out for 15-20 minutes before reheating to ensure even heating throughout.
Placing the calzone on a baking sheet lined with parchment paper or aluminum foil helps with cleanup while promoting even heat distribution, typically requiring 10-15 minutes for refrigerated calzones. For frozen calzones, you’ll need to extend the heating time to 18-20 minutes to ensure thorough warming without compromising texture.
The air fryer has emerged as a worthy alternative, offering oven-like results in less time. Set to 350°F, this appliance creates a wonderfully crisp exterior in just 5-8 minutes, with the added benefit of not heating up your kitchen.
For best results, flipping the calzone halfway through guarantees both sides receive equal attention.
Those seeking a compromise between speed and quality might consider a hybrid approach: briefly microwave the calzone to warm the interior, then finish in a skillet to restore crispness.
This method, while requiring more attention, delivers surprisingly good results without the wait time of oven reheating. A small splash of water in the covered skillet creates steam that helps heat the filling without overcooking the now-crispy exterior.
