Here’s your cheat sheet. Cut your leftover lasagne into a single-layer slice if it’s thick. More surface area = faster, more even heat.
Pop it on a microwave-safe plate with the damp towel. Microwave on medium power (50-70%) for one minute. Stir the air, let it rest for 30 seconds. Then hit it again for 30 seconds on high.
Why the break? Because heat continues to spread inside the food. Rushing is for toast. Lasagne demands a tiny pause.
