Ingredients for Roast Chicken with Kimchi Smashed Potatoes

  • 675g fingerling or baby Yukon Gold potatoes

  • 4 tablespoons vegetable oil, divided

  • Kosher salt, freshly ground pepper

  • 4 large skin-on, bone-in chicken thighs (about 675g total)

  • 2 garlic cloves, grated

  • 1 450g jar Napa cabbage kimchi, drained, 60ml liquid reserved

  • 1 tablespoon unseasoned rice vinegar

  • 4 cups trimmed bitter greens (such as mustard, mizuna, or rocket)

Preheat oven to 232°C. Toss potatoes and 1 tablespoon oil on a large rimmed baking sheet; season with salt and pepper. Roast, turning once, until browned in spots, 10-15 minutes.

Meanwhile, rub chicken with garlic and season with salt and pepper. Heat 1 tablespoon oil in a large skillet over medium-high heat. Cook chicken skin side down until golden brown and crisp, 8-10 minutes.

Arrange chicken skin side up on baking sheet among potatoes. Roast until chicken is cooked through and potatoes are tender, 15-20 minutes longer.

Using a large spoon, lightly smash potatoes. Scatter kimchi over; roast until kimchi is warm, about 5 minutes.

Meanwhile, whisk reserved kimchi liquid, vinegar, and 2 tablespoons oil in a small bowl.

Scatter greens over, drizzle with half of dressing, and toss gently. Divide among plates and drizzle with remaining dressing.
