This chicken dish is a whole meal on its own. There are so many different flavorful veggies, plus the juicy chicken thighs, that you won't even need a side dish. The best part? You can make a whole dinner using just one pan!
Preheat the oven to 375 degrees.2.
Season the chicken with salt and pepper. Heat the oil in a large, deep skillet over medium-high heat. Add the chicken thighs skin-side down and cook undisturbed until golden brown, 3-4 minutes. Remove the chicken thighs to a plate.3.
Reduce the heat to medium low and add the onions, mushrooms, garlic and crushed red pepper. Cook, stirring often, until softened, about 5 minutes. Add the wine and simmer until reduced by about half. Add the tomatoes, olives, oregano and 1/2 cup water and bring to a simmer; stir in butter and season with salt and pepper.4.
Nestle the chicken thighs in the sauce, skin-side up, and transfer to the oven. Bake until the chicken is just cooked through, about 40 minutes.5.
Sprinkle the dish with parsley and serve immediately.
