You can’t set a specific temperature on most microwaves, but the best way to reheat pizza is at medium power (50-70%) in 30-second intervals. This prevents the cheese from turning rubbery and the crust from becoming soggy. For a crispier result, use a microwave crisper pan or a cup of water to add steam.

Quick Answer

Microwaves don’t have temperature controls, so the key is power level and time. Medium power (50-70%) for 45-90 seconds, depending on slice thickness and microwave wattage. For best texture, pair with a crisper pan or paper towel.

  • Power Level: Use 50-70% power (medium) to heat evenly without overcooking edges.
  • Time: 30-45 seconds per slice, then check. Thick crust may need up to 90 seconds total.
  • Wattage Impact: Higher wattage (1200W) needs less time; lower (700W) needs more. Adjust accordingly.
  • Crispness Hack: Place a microwave crisper pan under the slice, or heat with a small cup of water to add moisture.

Why Microwave Temperature Matters

Unlike an oven, most microwaves don’t let you dial in a specific temperature like 350°F. Instead, you control power level, which adjusts how the magnetron cycles on and off. Full power (100%) blasts the pizza with intense energy, cooking the cheese and sauce too quickly while leaving the crust cold or soggy. Medium power (50-70%) gives the heat time to penetrate the dough and melt the cheese evenly.

Microwave wattage also plays a role. A standard microwave ranges from 700 to 1200 watts. If you have a 1000W microwave, medium power (50%) effectively delivers 500W, which is ideal for reheating. For lower wattage models, you may need to use 70% power and extend the time slightly.

Step-by-Step: Reheat Pizza in the Microwave

  1. Place a single slice on a microwave-safe plate. If you have a crisper pan, preheat it in the microwave for 2 minutes first.
  2. Set your microwave to 50-70% power (medium). If your microwave has numbered power levels, 5 or 6 out of 10 works well.
  3. Heat for 30 seconds. Check the pizza: the cheese should be melted but not bubbling, and the crust should be warm but not hard.
  4. If not hot enough, continue in 15-second bursts. Total time is usually 45-90 seconds for one slice.
  5. Let it rest for 30 seconds before eating—the cheese continues to melt and the crust firms up slightly.

How to Get a Crispier Crust in the Microwave

For a crispier bottom, use a microwave crisper pan (like the Masterbuilt or Presto models). Preheat the pan in the microwave for 2-3 minutes on high, then place the pizza slice on it and heat on medium power for 45-60 seconds. The pan’s metal coating absorbs microwaves and gets hot enough to crisp the crust.

No crisper pan? Place a paper towel under the slice to absorb excess moisture. Alternatively, microwave the slice on a piece of parchment paper or a microwave-safe rack to allow air circulation.

Reheating Multiple Slices: Temperature and Time Adjustments

When reheating two or three slices, arrange them in a single layer on a large plate. Increase the time by 20-30 seconds per additional slice, but keep the power level at 50-70%. For example, two slices may take 60-90 seconds at medium power. Check after 45 seconds and rotate the plate if your microwave doesn’t have a turntable.

Avoid stacking slices, as the middle ones won’t heat evenly. If you have a microwave crisper pan large enough, you can fit two slices side by side.

Alternative: Using a Microwave Convection or Combi Oven

If your microwave has a convection or combi mode, you can set an actual temperature. Preheat to 350°F, then place pizza directly on the wire rack or a baking sheet. Heat for 3-5 minutes, until cheese bubbles and crust is crisp. This combines microwave speed with oven-like browning.

For standard microwaves without convection, the power-level method remains your best bet. Some high-end models (like Panasonic Genius or Toshiba Combi) include a sensor reheat function for pizza—use that if available.

Pro Tips

  • Place a small microwave-safe cup of water in the corner of the microwave to add steam, keeping the crust from drying out.
  • If using a crisper pan, don’t oil it—the preheated surface will crisp without added fat.
  • For cheese that’s still cold in the center, try cutting the slice in half before microwaving to reduce thickness.
  • Let the pizza rest for 30-60 seconds after microwaving; the carryover heat finishes the job.

Common Mistakes to Avoid

  • Using full power: This makes the cheese rubbery and the crust tough or soggy.
  • Heating too long: More than 90 seconds per slice at medium power can dry out the pizza.
  • Stacking slices: They won’t heat evenly and the middle stays cold.
  • Skipping the rest period: Eating immediately risks burning your mouth and the cheese may slide off.

FAQ

Can I reheat pizza in the microwave without a crisper pan?

Yes. Place the slice on a paper towel to absorb moisture, or use a microwave-safe plate. Heat at 50-70% power for 30-60 seconds. The crust won’t be crispy, but it will be warm and palatable.

Why does my microwave pizza get soggy?

Sogginess happens when steam condenses on the crust. Use a lower power level (50%) and a shorter time, or place a paper towel under the slice. A crisper pan eliminates sogginess.

Is it safe to reheat pizza in the microwave more than once?

Yes, but each reheat degrades texture and flavor. Reheat only the slices you plan to eat immediately. Store leftovers in the fridge and consume within 3-4 days.

The Bottom Line

The microwave is the fastest way to reheat pizza, but it requires the right power level and timing. Stick with 50-70% power and short bursts to avoid rubbery cheese and soggy crust. For a crispier result, invest in a microwave crisper pan or use a convection microwave at 350°F. With these tips, you can enjoy leftover pizza that tastes almost as good as fresh.
