Fragrant Scallion Oil
Scallion oil is a base of slowly infused fat that carries the sharp, grassy edge of fresh scallions into everything from noodles to stir-fries. By frying the green parts in neutral oil until they are dark brown and crispy, you extract a toasted, nutty aroma that anchors simple dishes.
Watch the color, not the clock.
The goal is to extract flavor without burning the scallions to an acrid black, which turns the oil bitter. Keep your heat low and your eyes on the pan.
- Small heavy-bottomed saucepan
- Fine mesh strainer
- Glass jar for storage
What goes in.
- 2 bunchesscallions, whites and greens separated and cut into 2-inch lengths
- 1.5 cupsneutral oil, such as grapeseed or vegetable
- 2 slicesginger, smashed
Low and Slow Extraction
Start with the scallion whites and ginger to infuse the oil, adding the greens only once the whites begin to turn golden. This ensures the more delicate green parts do not carbonize before the oil is fully infused.
The method.
Heat the oil
Pour the oil into the cold saucepan. Add the scallion whites and smashed ginger over medium-low heat.
Infuse the base
Cook for 5-7 minutes. Watch for the scallion whites to turn a pale, light gold. Do not rush this or the ginger will brown too early.
Add the greens
Toss in the scallion greens. They will bubble vigorously. Reduce heat to low immediately.
Fry until crisp
Continue cooking for another 8-10 minutes, stirring occasionally. The greens are done when they are dark brown and feel brittle when pressed against the side of the pan with a wooden spoon.
Strain and cool
Remove the pan from the heat. Strain the oil through a fine-mesh sieve into a heatproof glass jar. Discard the ginger, but keep the crispy scallions to use as a topping.
Other turns to take.
Spicy Version
Add one tablespoon of Sichuan peppercorns or red pepper flakes to the oil during the last two minutes of frying for heat and numbing spice.
Aromatic Add-ins
Include a single star anise or a small piece of cinnamon bark during the initial infusion for a deeper, warmer profile.
When it doesn't go to plan.
Pat the scallions thoroughly dry with paper towels before adding them to the oil to prevent dangerous splattering.
Store the oil in the refrigerator to keep the flavor fresh; it will solidify, but melts instantly upon contact with hot food.
Use the leftover crispy scallions as a garnish for steamed tofu or congee.
The ones that keep coming up.
How do I know if the oil is burnt?
If the oil looks black rather than a deep, translucent amber, or if it smells like charred toast, it has gone too far and will taste bitter.
Can I use olive oil?
Avoid extra virgin olive oil. Its low smoke point and distinct flavor profile interfere with the clean, toasted scallion taste you are aiming for.
