"We have a flock of laying hens and usually an abundance of eggs. I'm always trying to find new ways to prepare them. Oh man are they good! It's a unique twist to the more traditional pickled egg recipes out there. These are great on salads, or just as is."
Place eggs in a large saucepan and cover with cold water. Bring to a boil; remove from heat, cover, and let sit until eggs are cooked through, about 10 minutes. Drain hot water; cover eggs with cold water.
Peel eggs and place in a quart-size Mason jar.
Combine soy sauce, water, sugar, minced onion, and sesame oil in a saucepan over medium heat. Cook and stir until sugar is dissolved, 3 to 5 minutes. Cool briefly, about 5 minutes. Pour over eggs in the jar.
Refrigerate eggs until flavors are absorbed, at least 6 hours.
