Pat the chicken thighs completely dry with paper towels. Trim any excess fat and shape the thighs so they are similar in size for even cooking.
Season both sides generously with kosher salt and white pepper. Sprinkle with all-purpose seasoning, then season the flesh side with Herbes de Provence.
Heat olive oil in a large braising pan or Dutch oven over medium-high heat.
Place chicken skin-side down in the pan. For an extra crispy crust, place a piece of parchment paper over the chicken and weigh it down with a heavy skillet. Sear for 5 to 7 minutes, until deeply golden brown.
Flip and cook for an additional 2 minutes. Remove chicken and set aside.
Add onions to the pan and sauté for 3 to 4 minutes until softened. Stir in garlic paste and cook for 30 seconds.
Deglaze the pan with white wine, scraping up all the browned bits from the bottom.
Add bone broth, white beans, and chopped kale. Stir to combine.
Nestle the chicken thighs back into the pan on top of the kale mixture.
Cover and reduce heat to low. Simmer for 25 to 30 minutes, or until the chicken is tender and easily pulls apart.
Stir in the chopped tomatoes during the final 5 minutes of cooking.
Taste and adjust seasoning as needed.
Serve over warm quinoa with plenty of broth spooned around the bowl. Garnish with Parmesan cheese and serve with toasted baguette for dipping if desired.
