Instructions

Season chicken thighs with salt, pepper, and paprika.
Heat olive oil in a large skillet over medium-high heat. Sear chicken skin-side down for 5–6 minutes, flip, and cook another 3–4 minutes. Remove and set aside.
In the same skillet, reduce heat to medium-low and caramelize onions for 10–12 minutes, stirring often.
Add garlic, thyme, balsamic vinegar, cayenne (optional), and a pinch of salt. Cook 2–3 minutes more.
Pour in chicken broth and scrape up browned bits. Simmer for 3 minutes.
If thickening, stir arrowroot with 1 tbsp water and add to skillet.
Nestle chicken into the onion mixture, cover, and simmer on low heat for 20 minutes, until fully cooked.
Garnish with chopped parsley and serve.

Notes

Boneless chicken can be used; reduce cooking time.

Add mushrooms with onions for extra umami flavor.

For a creamy variation, stir in a splash of coconut milk.

For more heat, increase cayenne or add red pepper flakes.
