Step 1

Set oven to 375F

Step 2

Season both sides of the chicken with salt, pepper, and red pepper flakes, to taste.

Step 3

Lightly coat the bottom of a large braising casserole or Dutch oven with olive oil and heat over medium high heat until the oil is quite hot, but not smoking. Brown the chicken, skin side down and in batches, for 3 minutes, then flip and cook for another minute. Remove to a baking sheet and finish baking in the oven, about 12-15 minutes, or until a thermometer reads 155F (it will rise to 165F while it rests. When done, cover loosely with foil.

Step 4

Meanwhile, saute the garlic, onion, and rosemary in the same pan the chicken was browned in. Add more oil if necessary and saute for about 5-7 minutes, until soft and golden. Add the stock, or stock and wine, to the pan and bring up to a bubble. Add the beans, and let simmer for a few minutes.

Step 5

Add the greens to the pan, a few handfuls at a time, stirring to wilt them.

Step 6

Smash some of the beans to thicken the sauce, and taste to adjust the salt, pepper, or red chili flakes. Add more fresh rosemary if you like.

Step 7

Nestle the chicken thighs back into the pan, and heat through.

Step 8

Serve topped with shavings of Parmesan.
