Time 40m

Number Of Ingredients 9

1 pound bite-size red potatoes (about 25), or larger red potatoes, halved
2 tablespoons extra-virgin olive oil
1/2 small head fennel (11 ounces), cut into a 1/2-inch dice (about 1 cup)
Kosher salt and freshly ground pepper
1 shallot, cut into thin rounds (about 1/3 cup)
2 cups well-shaken cold buttermilk
2 tablespoons packed finely shredded kale, for serving
Fresh dill sprigs, for serving
Flaky salt, such as Maldon, for serving

Steps:

Place potatoes in a steamer. Fill a large pot with 1 to 2 inches water; place steamer in pot. Bring water to a simmer, cover, and steam until potatoes are tender and easily pierced with a knife, 20 to 25 minutes.
Meanwhile, heat oil in a small skillet over medium. Add fennel; season with kosher salt. Cook,stirring occasionally, until fennel is starting to caramelize, 8 to 10 minutes. Add shallot; cookuntil golden brown and caramelized, about 5 minutes more.
Divide potatoes evenly among 4 bowls. Pour buttermilk over potatoes. Top each bowl with fennel mixture, kale, and dill. Season with flaky salt and pepper; serve.
