My aunt often bakes a large lasagna and has it for several days. She believes it stays edible for up to 17 days. What is the actual shelf life of lasagna in the fridge?

Lasagna, a beloved Italian dish, has become a staple in many households for its rich flavors and hearty portions. Oftentimes, it's made in large quantities, and leftovers are inevitable. But with any food kept for an extended period, food safety becomes a question.

While my aunt enjoys her lasagna over several days, you may wonder just how long it can be safely enjoyed from the confines of one's refrigerator. This question is particularly relevant for those who wish to savor their culinary creations while minimizing waste and ensuring food safety.

1. Freshly Baked Lasagna:

When you first make your lasagna, its shelf life depends on how quickly it cools down and how it's stored. Ideally, you should let it cool to room temperature within two hours of cooking and then store it in the refrigerator. It is not advised to leave freshly baked lasagna at room temperature for more than two hours due to the risk of bacterial growth.

2. Lasagna in the Refrigerator:

Properly stored, cooked lasagna will usually stay good for 3 to 5 days in the refrigerator. To ensure it remains safe to eat, store it in an airtight container or wrap it tightly with heavy-duty aluminum foil or plastic wrap.

3. Lasagna in the Freezer:

For longer storage, lasagna can be frozen. When frozen in proper airtight containers or freezer bags, lasagna can last for about 2 to 3 months while maintaining its best quality. Be sure to label the container with the date to keep track of how long it has been stored.

4. Reheating Lasagna:

When reheating your lasagna, ensure that it reaches an internal temperature of at least 165°F (74°C) to eliminate any potential bacteria that may have grown. It's best to reheat only what you'll be consuming in one sitting.

While my aunt's lasagna ritual of 17 days may be a testament to her confidence in her culinary hygiene and refrigerator's capabilities, the USDA and food safety experts would advise against following such a lengthy timeline. The risk of foodborne illness increases significantly as food items overstay their refrigerator's welcome. It's essential to heed the guidelines of keeping cooked lasagna for a maximum of 3 to 5 days in the fridge, or if you need more time, to freeze it for later enjoyment. Food safety should always be the top priority, even when it means parting ways with our beloved leftovers a little sooner than we'd like.
