As with other leftovers, reheating eggs can alter their taste and texture and may also cause some changes in nutritional value. While cooking is known to affect certain nutrients in foods, research on whether reheating already-cooked eggs significantly changes their nutritional profile remains limited, according to Healthline.

The biggest difference is usually in texture. Eggs that are reheated for too long can become dry, tough or rubbery.
How to reheat different types of eggs
Food safety starts before reheating. Eggs should be fully cooked to lower the risk of bacteria such as Salmonella. Once cooked, they should be placed in a shallow container so they cool quickly, refrigerated at 40°F (4°C) or below, and eaten within three to four days.
When reheating, eggs and egg dishes should reach an internal temperature of 165°F (74°C) to reduce the risk of foodborne illness.
The ideal reheating method varies depending on how the eggs were originally prepared:
-Scrambled eggs: Microwave for 20-30 seconds at a time, stirring after each interval until evenly heated.
-Omelets and quiches: Put them in an oven-safe dish and heat at 350°F (176°C) for 15-20 minutes. Frozen portions may require 25-30 minutes.
-Boiled eggs: Do not microwave them, as pressure can build up inside and cause the yolk to burst. Instead, place them in a heatproof bowl, cover with hot water and leave for around 10 minutes.
-Fried eggs: Reheat in a skillet with a small amount of butter or oil for 2-5 minutes without flipping.
-Poached eggs: Lower them into gently simmering water for 1-2 minutes before carefully removing them.
-Sunny-side-up eggs: Place on a lightly greased, preheated plate and microwave for about 30 seconds, then allow them to rest for one minute before eating.
The main goal is to heat eggs thoroughly while avoiding excessive cooking, which can quickly make them dry, chewy or rubbery.
