Is It Safe to Eat?
Absolutely. The green ring doesn’t affect flavor, nutrition, or safety. It’s simply a cosmetic change caused by overcooking. The yolk may be a little drier and carry a mild sulfur smell, but the egg is perfectly fine to eat.
Final Tip
If you’re making deviled eggs or a dish where presentation matters, follow the timing and cooling steps closely. Not only will you avoid the green ring, but you’ll also get tender whites and creamy, golden yolks — every single time.
