A microwave is one of the fastest ways to heat leftover pizza, and with a few simple tricks, you can get much better results.
In this guide, we will explain how to microwave pizza without making it soggy, how long to heat it, and whether the popular cup-of-water trick actually helps.
Why Does Pizza Get Soggy in the Microwave?
Pizza can become soggy in the microwave because microwaves heat the water molecules inside food. As the pizza heats, moisture from the cheese and toppings turns into steam. That steam can soften the crust instead of making it crispy.
Heating pizza for too long can also make the cheese rubbery and the crust chewy. This is why microwaving a slice for one or two minutes at once is usually not the best approach.
How to Reheat Pizza in the Microwave Without Getting Soggy
Follow these simple steps to get better results when reheating leftover pizza.
1. Place the Pizza on a Microwave-Safe Plate
Take the pizza out of its box and place it on a microwave-safe glass or ceramic plate. Arrange the slices in a single layer rather than stacking them.
Do not microwave pizza inside a cardboard box unless the packaging specifically states that it is microwave-safe. Also remove any metal clips, foil, or other metal materials before heating.
2. Add a Microwave-Safe Cup of Water
Fill a cup about halfway with water and put it beside the pizza in the microwave. The water absorbs some microwave energy and may help reduce excessive drying of the toppings and cheese.
However, the cup-of-water trick does not guarantee a crispy crust. If your pizza is already very moist, adding water may not improve the crust. Try it and compare the results with your particular microwave.
3. Microwave in Short Intervals
This is one of the most important tips for learning how to reheat pizza without making it soggy.
Start with about 20 to 30 seconds for one refrigerated slice. Check the pizza and continue heating in 10- to 15-second intervals until the cheese is hot and the slice is heated through.
Short intervals give you more control and help prevent the pizza from becoming overheated, chewy, or rubbery.
4. Let It Rest Before Eating
After heating, let the pizza sit for about 30 to 60 seconds. This allows the heat to distribute more evenly throughout the slice.
How Long to Reheat Pizza in the Microwave?
If you are wondering how long to microwave leftover pizza, the answer depends on the slice size, toppings, starting temperature, and microwave wattage.
| Pizza | Starting Time |
|---|---|
| One thin-crust slice | 20–30 seconds |
| One thick-crust slice | 30–45 seconds |
| Two slices | 40–60 seconds |
| Three or more slices | About 60 seconds, then check |
These are starting points rather than exact cooking times. A 700-watt microwave may need more time than a 1,000-watt microwave.
How Long to Microwave Pizza at Different Wattages?
Microwave power makes a noticeable difference. For one refrigerated slice, you can generally start with:
- 700 watts: about 30 seconds
- 800 watts: about 25–30 seconds
- 900 watts: about 20–30 seconds
- 1,000 watts: about 20–25 seconds
Check the pizza after the initial heating time and add 10-second intervals if necessary. This is much better than automatically microwaving pizza for one or two minutes.
How to Make Leftover Pizza Crispy in the Microwave
If your goal is to make leftover pizza crispy in the microwave, keep in mind that a standard microwave is not designed to brown food. It heats food quickly but does not produce the same dry heat as an oven or skillet.
Still, you can improve the texture with these tips:
- Do not overheat the pizza.
- Avoid tightly covering the pizza because trapped steam can soften the crust.
- Use a microwave-safe crisper pan if your microwave and the cookware manufacturer allow it.
- Try placing a microwave-safe paper towel underneath the slice to absorb some excess grease or moisture.
If you want a genuinely crispy crust, a skillet, oven, or air fryer will usually produce better results than a standard microwave.
How to Reheat Different Types of Pizza
Thin-Crust Pizza
Thin-crust pizza heats quickly, so start with 20 seconds and check it. Add short intervals if necessary. Avoid overheating because thin crust can dry out quickly.
Thick-Crust Pizza
For thick-crust pizza, start with around 30 seconds. Continue in 10- to 15-second intervals until the center is hot.
Frozen Pizza
Frozen pizza slices generally require more time than refrigerated pizza. Follow the package instructions when available, or use the microwave’s defrost setting before reheating if appropriate.
Why Is My Pizza Soggy After Microwaving?
If your pizza is soggy after microwaving, you may be heating it for too long or allowing too much steam to collect around the crust.
Try reducing the heating time and using shorter intervals. Heating one slice at a time can also help. If the pizza has particularly moist toppings, removing some excess moisture before heating may improve the texture.
Frequently Asked Questions
Can You Reheat Pizza in the Microwave Without It Getting Soggy?
Yes. Use short heating intervals and avoid excessive steam. A microwave-safe cup of water may also help with the overall texture, although it will not necessarily make the crust crispy.
Does Putting a Cup of Water in the Microwave With Pizza Work?
It can help change the way the pizza heats and may prevent some drying. However, results vary depending on the pizza and microwave. It is worth trying, but it is not a guaranteed solution for a soggy crust.
How Long Should I Microwave One Slice of Pizza?
For a refrigerated slice, start with 20 to 30 seconds. Check it and add 10-second intervals until it is hot enough. Thick slices may require additional time.
Can You Make Pizza Crispy Again in the Microwave?
A regular microwave can warm pizza, but it usually cannot produce the same crispy crust as an oven or skillet. A microwave crisper pan may improve the results.
Final Thoughts
Knowing how to reheat pizza in the microwave without making it soggy mostly comes down to controlling heat and moisture. Start with 20 to 30 seconds for one refrigerated slice, check it frequently, and continue in short intervals rather than overheating it.
You can also try the cup-of-water method or a microwave-safe paper towel to see which technique works best for your pizza. And if a crispy crust is your top priority, finish the pizza in a skillet, oven, or air fryer.
