Best Way to Reheat Leftover Pizza: 6 Methods Ranked
Cold pizza straight from the fridge has its fans. But if you want a slice that actually tastes like pizza again — crispy base, gooey cheese, toppings that haven’t turned to rubber — how you reheat it matters more than most people think. Some methods take two minutes; others take ten. Some restore the crust beautifully; others steam it into a soggy disappointment.
This guide ranks six common reheating methods from best to worst, explains the science behind why each one works (or doesn’t), and gives you exact settings to follow.
1. Skillet on the Stovetop — The Everyday Winner
A heavy pan on the stovetop is the fastest route to a crispy crust without drying out the cheese. It’s the method most pizza insiders actually use at home.
How to do it:
- Place a dry, non-stick or cast-iron skillet over medium heat.
- Add the cold slice directly to the pan — no oil needed.
- Cover loosely with a lid or a piece of foil.
- Heat for 2–3 minutes until the base is crisp and the cheese is melted.
The lid traps just enough steam to melt the cheese from above while the direct heat crisps the crust from below. Remove the lid for the final 30 seconds if you want extra snap.
Why it works: Direct conductive heat from the pan dries out excess moisture in the dough without the harsh, circulating heat that an oven can apply unevenly. The lid creates a mini convection environment on top.
Best for: One or two slices, quick weeknight reheats.
2. Conventional Oven on a Baking Sheet — Best for a Batch
If you have half a pizza to warm up, the oven is the most reliable method for even, consistent results across multiple slices.
How to do it:
- Preheat your oven to 375°F (190°C).
- Place slices on a baking sheet lined with foil (or directly on the oven rack for maximum crispiness).
- Heat for 8–10 minutes.
- Check at 8 minutes — the cheese should be bubbling and the crust firm.
Skip the microwave-safe plate and use metal. Metal conducts heat to the base; ceramic insulates against it.
A useful trick: Put the baking sheet in the oven while it preheats. Placing cold slices on a hot tray jump-starts crust crisping the same way a preheated pizza stone does.
Best for: Feeding two or more people, thick-crust pizzas like Sicilian or deep dish.
3. Air Fryer — Fast, Crispy, Surprisingly Good
The air fryer has earned its reputation here. It circulates hot air at high velocity, which evaporates surface moisture quickly and crisps the crust in a fraction of the oven’s time.
How to do it:
- Preheat the air fryer to 325°F (163°C).
- Place slices in a single layer in the basket — don’t stack them.
- Heat for 3–4 minutes.
- Check and add 1 minute at a time if needed.
Because air fryers vary by brand and wattage, the first time you try this you may need to experiment. A large basket air fryer at 350°F can reheat a slice in as little as 2.5 minutes.
Caution: Air fryers can over-dry thin crust slices. If you’re working with a very thin or cracker-style crust, check at 2 minutes and drop the temperature to 300°F.
Best for: One or two slices, thin-to-medium crust pizzas, when you want oven results without heating a full oven.
4. Oven with a Pizza Stone — The Closest to Fresh
If you own a pizza stone or a steel baking slab, this method produces results that are genuinely close to fresh-baked. The stone draws moisture out of the dough more aggressively than a metal tray does.
How to do it:
- Place your pizza stone in the oven and preheat to 400°F (205°C). Let the stone heat for at least 20 minutes.
- Slide the cold slice directly onto the hot stone.
- Heat for 5–7 minutes.
The high-heat stone rapidly heats the base while the surrounding oven air handles the top. The result: a crust that’s charred at the edges in a good way and firm all the way through.
The trade-off: This takes 20–25 minutes from start to finish once you count the preheat. Not practical for a quick snack, but worth it for a good Neapolitan or New York–style slice.
Best for: Serious pizza lovers, thin or medium crust, occasions where quality matters more than speed.
5. Microwave — Convenient but Compromised
Everyone does it. Let’s be honest about what it gets you.
A microwave heats food by exciting water molecules throughout the slice simultaneously. This means the crust, which contains less water than the sauce or cheese, tends to go rubbery while the toppings get unevenly hot. You end up with a slice that’s steamed rather than baked.
That said, there is one trick that genuinely helps:
The cup of water trick:
- Place your slice on a microwave-safe plate.
- Put a microwave-safe mug filled halfway with water next to the plate.
- Microwave on medium power for 45–60 seconds.
The water absorbs some of the microwave energy, slowing the cooking slightly and reducing the rubbery texture. The crust won’t be crispy, but it’ll be less chewy.
This works well enough for breakfast-pizza-on-the-go scenarios. It does not rival any of the methods above for quality.
Best for: When speed is the only factor. Not recommended for thick crusts — they go dense and gummy.
6. Toaster Oven — Decent, with Caveats
A toaster oven sits between a microwave and a full oven. It can produce acceptable results, but it has one significant flaw: the heating element is so close to the food that cheese often burns before the crust has properly crisped.
How to do it:
- Preheat to 350°F (175°C).
- Place slices on the wire rack (not the tray) to allow airflow underneath.
- Heat for 5–7 minutes, watching closely after 4 minutes.
If your toaster oven has a convection setting, use it — it distributes heat more evenly and reduces the burn risk.
Best for: When a stovetop, air fryer, and full oven are all unavailable. Treat it as a backup option.
Handling and Storage: What You Do Before Reheating Matters
The best reheating method can only do so much if the pizza was stored poorly.
- Refrigerate within two hours. Food safety guidelines from the USDA recommend not leaving cooked food at room temperature for more than two hours. Pizza sitting out overnight is not safe to eat, regardless of how it looks.
- Store slices flat, not stacked. Stacking compresses toppings and causes the cheese to stick and tear. Lay slices in a single layer in an airtight container, or wrap each individually in foil.
- Consume within 3–4 days. After that, quality drops significantly and safety becomes a concern.
- Bring slices closer to room temperature before reheating. Taking pizza out of the fridge 10–15 minutes before heating helps the center warm through without overcooking the edges.

A Quick Reference: Which Method to Choose
| Method | Time | Crust Result | Best Slice Count |
|---|---|---|---|
| Skillet | 3–4 min | Crispy | 1–2 |
| Oven (tray) | 8–10 min | Consistent | 3+ |
| Air Fryer | 3–4 min | Very crispy | 1–2 |
| Pizza Stone | 5–7 min (+preheat) | Closest to fresh | 1–3 |
| Microwave | 1 min | Soft/chewy | 1 |
| Toaster Oven | 5–7 min | Variable | 1–2 |
The Verdict
For a single slice on a regular day, the skillet method wins on ease and quality. For a larger batch, the oven with a preheated tray is more practical. If you have an air fryer and a medium-crust pizza, that’s arguably the most convenient high-quality option.
The microwave is fine if speed is genuinely the only thing that matters — but don’t kid yourself that it’s producing the same result. The cup-of-water trick helps at the margins.
The one consistent piece of advice across all methods: don’t rush the preheat. A cold pan, cold tray, or cold stone gives up most of the advantage these methods have over the microwave. Heat your surface first, and the pizza will take care of itself.
