How to Reheat Roasted Vegetables So They're Crispy Again

Roasted vegetables lose their crispness in the fridge, and the microwave only makes that worse by turning them soft and a little soggy instead of bringing back the browned, caramelized edges you roasted them for in the first place.

Why Roasted Vegetables Go Soggy in the Microwave

Microwaves cook with moist heat, which is the opposite of what made the vegetables crispy the first time around (dry, high heat that evaporates surface moisture). Reheating them in the microwave just steams them instead, leaving you with soft, slightly wet vegetables instead of the crisp edges you started with.

The Best Method: Oven or Air Fryer

Preheat your oven to 425°F, spread the vegetables in a single layer on a baking sheet (crowding them traps steam and defeats the purpose), and roast for 8-10 minutes, until they're heated through and the edges have crisped back up. An air fryer at 375°F for 4-6 minutes works even faster and gets similarly crisp results.

Why a Single Layer Matters So Much

Piling vegetables on top of each other traps moisture between the layers, which steams the vegetables at the bottom of the pile instead of letting the dry oven heat do its job. Spreading them out, even if it means using two baking sheets, makes a bigger difference than almost anything else in this guide.

Skip the Microwave If You Can

If you truly only have a microwave available, spread the vegetables out on a plate rather than piling them in a bowl, and microwave uncovered in short bursts. Leaving them uncovered lets at least some moisture escape instead of trapping it against the vegetables.

How Long Reheated Roasted Vegetables Last

Roasted vegetables keep for 3-5 days in the fridge. They reheat well multiple times as long as you stick to the oven or air fryer method, since the crisping process doesn't really depend on how many times you've done it before.

A dish like roast potato and pumpkin wedges with rosemary salt comes back to life especially well in the air fryer, since the wedge shape gives plenty of surface area to re-crisp.
