Another food myth has to do with people leaving food out overnight, Hanes says. They may have made a big pot of soup, chili or lasagna, and they fell asleep or forgot to put it away. We say anytime a perishable food item has been left out at room temperature for more than two hours, you should throw it away. 3 Answers. Throw this out. The general rule of thumb is that food that isn't otherwise preserved (through large quantities of acid or sugar for example) must not be in the danger zone from 40-140 degrees Fahrenheit for more than 2 hours. Rice and pasta can contain bacteria whose spores survive the cooking process. If boiled rice or pasta are left out at 12-14o C for a long time (more than 4-6 hours), it can become extremely dangerous to eat. Then they will be safe to eat. Depending on how good your immune system is you might be fine if you eat it.

I wouldn't put hot lasagna directly into the fridge, though, as it will raise the temperature of your fridge. Let it cool for a little while, maybe even let it sit on some ice, then refrigerate. You can re-heat it all at once, in a low temperature (250°F or so) oven, or cut into individual servings and microwave it.

A: If you assemble and bake the lasagna ahead of time, you shouldn't keep it longer than three days in the refrigerator. If you need to keep it longer, it would be better to freeze it and reheat it. If you just need to make it a day ahead, you could refrigerate it before baking it.
