After you make these umami green beans, you'll never want to make green beans another way again. The char adds an addictive sweetness like nothing else. It will knock your socks off!
Sauté the green beans in the oil over medium/medium-high until charred on at least one side, tossing occasionally, ~10 minutes
When cooked, add the scallion whites and garlic. Cook for 5 more minutes, tossing to make sure the green beans are well coated and charred all over.
Add the soy sauce, mirin, sugar, scallions, and garlic. Cook ~1 minute.
Serve immediately!
Notes
The more charred the green beans are, the more delicious they will be.Cook in a cast iron pan for extra char!Keep a splash guard handy. The green beans will spatter when they hit the oil because of their water content.
