½ cup (1 stick)
salted butter, cut into 8 equal pieces
1
bunch of sage, (about 20 leaves)
1
large, firm sweet apple, such as Honeycrisp or Fuji, cored and thinly sliced
Flaky salt
Freshly cracked black pepper
Method
Fill a large pot with 3 quarts water and add the kosher salt. Bring to a boil over high heat. Add the green beans and cook until bright green and nearly softened, about 3 to 4 minutes total. Drain.
Meanwhile, toast the pecans in a medium skillet over medium heat, stirring often, until fragrant and beginning to brown, about 5 minutes. Transfer to a small bowl.
Add the butter to the same skillet. When it begins to bubble, add the sage leaves. Reduce the heat to low and simmer until the sage leaves are beginning to crisp and the butter begins to brown, 2 to 3 minutes. Using a slotted spoon, transfer the sage leaves to a plate.
Add the green beans, apples, and pecans to the brown butter. Toss to coat and cook until the green beans are tender and the apples are warmed through, about 4 more minutes.
Season with flaky salt and black pepper. Garnish with the crispy sage leaves and serve warm.
