Preheat your oven to 450F.
In a bowl, mix up the rosemary-garlic vinaigrette by combining the minced rosemary, garlic, olive oil, juice of 1 lemon, and seasoning with salt and pepper to taste.
2 sprigs of fresh rosemary, 3 cloves garlic, 2 lemons, 2 tbsp. extra-virgin olive oil, Sea salt and freshly ground black pepper, 4-6, bone-in chicken thighs
Coat each chicken piece with the vinaigrette.
Heat an oven-safe skillet over a medium-high and sear the chicken, skin-side down, until browned, about 5 minutes.
Remove the chicken from the pan and add the mushrooms. Then return the chicken to the pan on top of the mushrooms and drizzle with the remaining vinaigrette and the juice from the other lemon.
20 oz about 1 lb mixed mushrooms, cut in half
Add the rosemary sprig and the squeezed lemon halves to the skillet and place in the oven.
1 tbsp. fresh rosemary leaves
Roast for 20 to 25 min.
