Physics does not apply to lasagna.
Also I suck at making lasagna.
(I also imagine using the circulation in a convection oven might help as well. Also, preheating your oven! Even if it's a toaster oven.)
Use the power button to select a lower power level, and cook the food for longer.
Cooking food for 2 minutes at 50% power gives a noticeable difference in average temperature compared to cooking food for 1 minute at 100% power and waiting a minute.
And I don't always know what it decides to do as far as turning the magnetron on and off on its sensor modes, but it'll spend a while doing automated reheat and potatoes and what not and it'll be dang near perfect every time.
Don't get me wrong I'd love an inverter microwave, truly a better option. But its not like the duty cycle process has no impact.
It's a GE Profile model FWIW. It seems like a good product line from my experiences. The matching oven has also been a good performer overall.
I am still convinced the lava cheese insulator is there only to burn people's insides with boiling pineapple.
Although pineapple flavoured floor heating does sound delicious.
Cheese melting takes energy Cheese freezing, releases energy.
So you do actually get the temperature to remain at the melting point of the cheese for a longer period of time if you have enough % cheese to be significant.
Most people think they should be able to put food in, nuke it at full power for as short of a time as possible, and then immediately shove it in their face with no consequence and we all know that doesn't work yet most of us will keep doing it anyways.
