Can I eat an omelette the next day?

Eating leftovers is a great way to save time and reduce food waste. However, some foods are safer to eat as leftovers than others. Omelettes fall into a bit of a gray area when it comes to leftovers. There are some risks associated with eating leftover omelettes, but also ways to safely enjoy your omelette the next day. Read on to learn more about the safety, storage, and reheating of leftover omelettes.

Is it safe to eat a leftover omelette?

Omelettes contain eggs, which are a perishable food due to their protein content. Bacteria grow quickly on perishable foods at room temperature. As a general rule, perishable foods like omelettes are only safe to eat within 3-4 days of cooking when properly stored in the refrigerator.

After cooking, omelettes can still harbor some bacteria. Proper storage slows further bacteria growth. But if stored incorrectly at room temperature for too long, the bacteria in an omelette could multiply to unsafe levels and cause foodborne illness.

So as long as you promptly refrigerate and eat the omelette within 3-4 days, it should be safe to eat. Follow the guidelines below for safe omelette storage.

How to store an omelette safely

Here are some tips for safe storage of leftover omelettes:

  • Refrigerate omelettes within 2 hours of cooking. Do not leave them sitting out at room temperature.
  • Store omelettes in shallow airtight containers so they cool quickly in the fridge.
  • Use omelettes within 3-4 days for optimal safety and quality.
  • Label containers with the date cooked for easy tracking.
  • Do not store omelettes for longer than 5 days total, even in the fridge.
  • Freeze omelettes for longer storage. They will keep for 2-3 months in the freezer.

Following proper refrigeration and use-by dates is important for all leftovers, especially high protein foods like omelettes.

Reheating omelettes

The right reheating method also plays a role in omelette safety. Simply letting an omelette sit out at room temperature can allow bacteria to multiply to dangerous levels. Instead, use these safe reheating methods:

  • Microwave omelettes until steaming hot throughout.
  • Heat omelettes on the stovetop over medium-low, stirring frequently.
  • Place an omelette slice between two pieces of toast to make an open-face sandwich, then toast in a hot oven or panini press.

Microwaving and pan frying are fast, effective ways to thoroughly reheat omelettes to an internal temperature of 165°F. This temperature kills any bacteria that may have multiplied during storage.

Avoid any reheating method that leaves room for cold spots in the middle, like a quick zap in the microwave. Check the internal temperature in a few spots using a food thermometer if concerned.

How does refrigeration affect omelette quality?

While refrigeration keeps omelettes safe to eat for 3-4 days, it can degrade their texture and flavor over time. Here’s what happens to an omelette in the fridge:

  • Moisture loss causes drying.
  • Eggs take on fridge odors.
  • Texture becomes less fluffy.
  • Filling ingredients may weep liquid.

The omelette will still be edible, but it won’t be as soft, fluffy, or freshly aromatic after sitting in the fridge for a few days. Reheating will also compound the drying effect.

For best results, eat omelettes within 2 days of cooking. Within 3-4 days, they are still safe to eat but just less appetizing.

Can omelettes be frozen?

Freezing is a great way to extend the shelf life of cooked omelettes. To freeze:

  • Cool omelettes completely before freezing.
  • Wrap tightly in plastic wrap, then foil or freezer bags.
  • Label with date and contents.
  • Freeze for up to 2-3 months.

Frozen omelettes may suffer some loss of texture, but will be much closer to freshly cooked compared to refrigerating.

Thaw frozen omelettes overnight in the fridge before reheating. You can also reheat directly from frozen using a microwave or oven. Just allow a few extra minutes of cooking time when reheating from frozen state.

Can you eat reheated omelettes cold?

It’s not recommended to eat leftover omelettes without reheating them first. Any bacteria present could multiply to unsafe levels at room temperature over time.

However, if you reheat an omelette thoroughly and want to eat any uneaten portions later, you have some options:

  • Refrigerate within 2 hours of initially cooking.
  • Eat cold within 3-4 days.
  • You can reheat a second time, but quality declines.

The key is promptly refrigerating after the initial reheating to prevent bacterial growth. But for best taste and texture, omelettes are best enjoyed freshly cooked or within a day or two.

Should you add anything to leftover omelettes before reheating?

Adding a splash of milk or cream before reheating can help revive a leftover omelette’s texture. The added moisture counteracts drying from fridge storage. Beat the milk into the eggs briefly before reheating.

You can also add fresh fillings before reheating, like:

  • Chopped tomatoes, onions, spinach
  • Crumbled cheese
  • Sautéed mushrooms
  • Chopped cooked meat

This transforms your leftover plain omelette into an omelette skillet meal. Just take care not to overfill or the omelette may fall apart.

Avoid adding any raw meat, poultry, or eggs when reheating omelettes. These need to be fully cooked to be safe to eat.


Enjoying your leftover omelette within 3-4 days is usually safe, as long as it has been promptly refrigerated and thoroughly reheated before eating. For best results, eat within 2 days of cooking and reheat gently using a microwave, stovetop, or oven. Adding a splash of milk and fresh fillings can jazz up leftover omelettes. Freezing also preserves omelettes for 2-3 months. Follow these guidelines and leftovers like omelettes can be a tasty, safe way to save time and reduce waste.

Frequently Asked Questions
