Room Temperature Safety

The 2-hour rule: Do not leave perishable foods, including cooked lasagna, at room temperature for more than 2 hours. If the ambient temperature is above 90°F (32°C), the limit is 1 hour.

The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).

Promptly refrigerate or freeze cooked lasagna to prevent bacterial growth. Discard any lasagna left in the danger zone for too long.

Expert Tips

Safe Handling

1

Reheat all leftovers, including veggie lasagna, to an internal temperature of 165°F (74°C) as measured with a food thermometer.

2

When reheating in a microwave, cover and rotate the food for even heating. Allow standing time. Reheat until steaming hot.

3

Do not leave cooked lasagna at room temperature for more than 2 hours (1 hour if the temperature is above 90°F/32°C).

4

Prevent cross-contamination by using separate cutting boards and utensils for raw ingredients (if preparing from scratch) and cooked foods.
