Instructions
Prepare scallions, shallots, and garlic
Wash scallions thoroughly. Pat dry with paper towels to prevent oil splatter. Cut off roots. Separate white and green parts. Cut both into 2-inch sections. Slice shallots and garlic thinly.
Time: PT7M
Heat oil and fry aromatics (white scallion, shallot, garlic)
Pour oil into a large skillet or wok. Heat over medium until small bubbles appear (about 160-170°C). Lower heat to low. Add white part of scallion, sliced shallots, and garlic. Stir gently and fry until pale golden (about 8 minutes). Remove with slotted spoon.
Time: PT10M
Temperature: 160-170°C
Fry green part of scallion
Add green scallion sections to the same oil over low heat. Stir and fry until they turn dry and browned but not burnt (about 5 minutes). Remove immediately.
Time: PT5M
Temperature: Low heat
Make scallion oil sauce
With oil still on low heat, add light soy sauce, dark soy sauce, and sugar. Stir until sugar dissolves (about 2 minutes). Optionally, add lard and/or chopped dried shrimp for extra flavor. Return fried green scallions to the pan and stir to coat. Cook until scallions absorb sauce color (about 2 minutes). Remove from heat.
Time: PT4M
Temperature: Low heat
Cook noodles
Bring a medium saucepan of water to a boil. Add dried noodles and cook according to package instructions (usually 4-5 minutes) until just al dente. Drain immediately in a colander.

Chef Tips from the Video
- Use fresh, thin scallions for best flavor and texture.
- Shanghai dried noodles have the ideal chewy texture, but spaghetti can work in a pinch.

Troubleshooting
Scallions turn bitter.
They were over-fried; remove from oil as soon as browned.
Oil splatters excessively.
Scallions were not dried well enough; always pat dry thoroughly.
Noodles are too soft.
Reduce cooking time and check for doneness earlier.
Sauce is too salty.
Use low-sodium soy sauce or reduce soy sauce amount.
Storage
Refrigerator: Store leftover scallion oil in a sealed jar for up to 2 weeks.
Freezer: Not recommended for scallion oil; noodles can be frozen plain, not with sauce.
Room temperature: Scallion oil can be kept at room temperature for up to 1 day, but refrigerate for longer storage.
Make-Ahead Tips
- Scallion oil can be made in advance and refrigerated.
- Noodles are best cooked fresh, but sauce can be prepared ahead.
