Step 1

Heat oil in a large Dutch oven or skillet with a lid over medium. Cook bacon, stirring occasionally, until starting to brown, about 5 minutes. Add shallots and cook, stirring occasionally, until shallots are softened and bacon is brown and crisp, 8–10 minutes.

Step 2

Increase heat to high and add wine, garlic, and rosemary to pot. Cook, stirring, until wine is reduced by half, about 1 minute. Add tomatoes along with their juices, broth, salt, and red pepper flakes and bring liquid to a boil. Reduce heat to medium; nestle in chicken, skin side up. Top with kale, cover pot, and cook until kale is wilted, 5–7 minutes. Stir kale into sauce and continue to cook, uncovered, until chicken is warmed through, about 5 minutes more.
