Step 1

Arrange a rack in the middle of the oven and heat to 450°F.

Step 2

Heat 1 tablespoon of the oil in a large oven-safe skillet with a lid over medium-high heat until shimmering. Season the chicken on both sides with salt and pepper. Place skin-side down in the pan and sear until golden-brown, about 5 minutes. Flip and sear until the other side is golden-brown, 4 to 5 minutes more. Transfer skin-side up to a plate.

Step 3

Add the remaining 1 tablespoon of oil to the skillet along with the mushrooms. Sauté, scraping up the browned bits at the bottom of the pan, until browned and just tender, about 5 minutes. Stir in the sun-dried tomatoes, rosemary, garlic, 1/2 teaspoon of salt, and a few grinds of black pepper. Sauté for 1 minute more. Stir in the white beans and broth.

Step 4

Nestle the seared chicken breasts skin-side up in the mushroom mixture, and add any accumulated chicken juices on the plate. Roast uncovered until the thickest piece of chicken reaches an internal temperature of 165°F, about 30 minutes. Serve in shallow bowls, spooning some of the sauce over the chicken and vegetables.
