Zesty Lemon Noodle Soup
Soft-Boiled Egg
A bright and refreshing noodle soup featuring a clear umami broth, citrusy lemon highlights, and a jammy soft-boiled egg for a perfect summer lunch.
This dish is a modern take on light Asian noodle soups, often enjoyed in warmer months when a heavy broth feels too taxing. The addition of fresh lemon slices elevates the savory soy base with a clean acidity that cuts through the richness of the sesame oil and egg yolk.
Ingredients
- 1 serving thin white wheat noodles
- 1 lemon, thinly sliced
- 1 soft-boiled egg
- 2 slices ham or cooked meat
- 1 tsp white seasoning powder or bouillon
- 2 cloves garlic, minced
- 1 tbsp pickled vegetables (zha cai)
- 1 tbsp dark soy sauce
- 12 tsp toasted sesame oil
- 2 stalks green onions
- 20 g white radish, julienned
- to taste chili oil
Instructions
- 1Add the base seasoning

Begin by adding a small spoonful of white seasoning powder into a clean white ceramic bowl. This forms the foundational savory base for your lemon noodle soup broth.
Tip: Adjust the amount of seasoning powder based on your salt preference, as the soy sauce added later will also contribute saltiness. - 2Incorporate fresh garlic

Add several slices of freshly minced or sliced raw garlic into the bowl. The garlic will infuse the hot broth with a sharp, aromatic depth as soon as the water is added.
Tip: For a more intense garlic flavor, you can lightly crush the slices before adding them to release more natural oils. - 3Add pickled vegetables

Use a knife to slide a portion of chopped pickled vegetables, such as zha cai, into the bowl. These add a unique crunch and a fermented tang that balances the richness of the soup.
Tip: If your pickled vegetables are very salty, give them a quick rinse before chopping to control the final sodium level of the soup. - 4Toss in green onions

Sprinkle a handful of freshly chopped green onions into the seasoning mixture. The green onions provide a bright color contrast and a mild, oniony freshness to the bowl.
Tip: Use both the white and green parts of the onion for a better balance of texture and sharp flavor. - 5Season with soy sauce

Pour a splash of dark soy sauce into the bowl. This adds a rich, umami depth and gives the final broth a beautiful amber color.
Tip: Dark soy sauce is thicker and less salty than light soy sauce; use it primarily for color and a mellow savory note. - 6Finish with sesame oil

Add a few drops of toasted sesame oil to the aromatics. This final liquid addition provides a nutty aroma that will bloom once the hot water hits the bowl.
Tip: Sesame oil is very potent; a few drops are usually enough to scent the entire bowl without overpowering the other flavors. - 7Boil the noodles

Bring a pan of water to a boil and add the thin white noodles. Use a spatula or chopsticks to stir them gently, ensuring they cook evenly and dont stick together. Cook until they reach your desired level of tenderness.
Tip: Keep a close eye on the noodles as thin varieties cook very quickly and can become mushy if left too long. - 8Prepare the soup base

While the noodles are finishing, take a ladle of the hot cooking water and pour it into your bowl containing the seasonings, garlic, and oil. Stir well to dissolve the ingredients and create a flavorful, steaming broth.
Tip: Using the starchy noodle water adds a slight silkiness to the broth compared to using plain boiling water. - 9Combine noodles and broth

Once the noodles are perfectly cooked, use chopsticks to lift them out of the boiling water, letting the excess moisture drain for a second. Place the noodles directly into the prepared bowl of hot soup base.
Tip: Transfer the noodles immediately to the soup to prevent them from sticking together or overcooking in their own residual heat. - 10Garnish with green onions

Sprinkle a generous handful of freshly chopped green onions over the center of the noodles. This adds a pop of bright color and a mild, fresh onion flavor that cuts through the richness of the sesame oil.
Tip: Save some of the green onions to use as a final topping after the noodles and other garnishes are added for maximum freshness. - 11Add fresh lemon slices

Place three thin slices of fresh yellow lemon onto the side of the noodle bowl. These slices provide a bright, citrusy aroma and a refreshing tang that balances the savory depth of the broth as they steep.
Tip: Use seedless lemon slices or remove the seeds beforehand to ensure a smooth eating experience. - 12Garnish with soft-boiled egg

Add two halves of a perfectly soft-boiled egg to the bowl. The creamy, jammy orange yolks add a rich texture and extra protein, making the soup more nutritious and visually appealing.
Tip: To get that perfect jammy yolk, boil your eggs for exactly 6 to 7 minutes and plunge them immediately into an ice bath. - 13Finish with chili oil

For the final touch, place a small spoonful of red chili oil paste directly on top of the shredded vegetables. This adds a layer of heat and a beautiful pop of red color to the refreshing soup.
Tip: If you prefer a milder soup, you can serve the chili oil on the side so guests can adjust the spice level themselves.
