When I eat soba noodles, I always pair them with Soy-Marinated Eggs. These eggs are incredibly simple to make, yet their flavor is rich and deeply satisfying—especially in the summer when served chilled.
Since my household consumes eggs at a rapid pace, I often marinate a large batch at once, ensuring we have a delicious, protein-packed snack ready to go. My version is low-fat, high-protein, and lightly seasoned, making it a great option for a healthy diet.
The key to a perfect soy-marinated egg is patience. Letting the eggs soak in the marinade for at least six hours ensures that the flavors penetrate deeply. The result? A creamy, runny yolk encased in a savory, umami-packed egg white—refreshing and incredibly satisfying on a hot summer day. 
What Makes Soy-Marinated Eggs Special?
These Japanese-inspired eggs, commonly known as Ajitsuke Tamago (味付け玉子) or ramen eggs, are more than just a side dish. They add a burst of umami flavor to various meals, from rice bowls to salads and, of course, ramen.
Unlike traditional hard-boiled eggs, these eggs feature a soft, jammy yolk that oozes with flavor. The secret lies in the perfect boiling time and an umami-rich soy marinade.
