Step 1

Heat oven to 450°F. Heat 1 teaspoon oil in large oven-safe skillet on medium. Season chicken breasts with 1/2 teaspoon each salt and pepper. Cook, skin sides down, until golden brown and crisp, 5 to 7 minutes.

Step 2

Turn; add cherry tomatoes, rosemary and fennel seeds; drizzle with 1 tablespoon oil and season with 1/4 teaspoon each salt and pepper, then roast until chicken is just cooked through and tomatoes have begun to break down, 12 to 15 minutes.

Step 3

Meanwhile, prepare polenta.

Step 4

Discard rosemary; transfer chicken to cutting board and let rest 5 minutes. Stir red wine vinegar into tomatoes, then toss with parsley. Remove bone from chicken, slice and serve on polenta. Top with tomatoes.
