1 | (3 1/2-pound) chicken, cut into 8 pieces (or use 3 1/2 pounds bone-in chicken parts) |
2 | teaspoons kosher salt (Diamond Crystal), plus more as needed |
1/2 | teaspoon freshly ground black pepper, plus more as needed |
6 | garlic cloves, sliced thinly |
2 | tablespoon extra-virgin olive oil, plus more as needed |
3 | tablespoons unsalted butter |
1 | cup thinly sliced mushrooms (preferably specialty mushrooms, such as king, hen-of-the-woods, chanterelles or black trumpet, or a combination) |
2 | large leeks (4 cups), halved and thinly sliced into half-moons (use white and light green parts) |
1 | tsp dried rosemary |
3/4 | cup dry white wine (or use a dry red or rosé) |
1/4 | cup sour cream |
1 | large lemon, zested, and lemon juice from 1/2 lemon |
Pat chicken dry with paper towels. Season all over with 1 1/2 teaspoons salt and the black pepper. Add half the garlic to the chicken. Pan fry on medium heat until cooked through. Transfer chicken to a plate.
Add 2 tbsp butter to the pan. Once the butter melts, add sliced garlic, leeks and a large pinch each of salt and pepper. Cook, stirring occasionally, until leeks are tender and golden brown, 7 minutes. Add rosemary, mushrooms and wine to the pot and let simmer, scraping up the browned bits, until liquid reduces by half, about 2 minute.
Stir in the sour cream, 1 tbsp butter, lemon zest and juice from half a lemon. Taste sauce and add more salt and lemon juice if needed. Return chicken to the pot.
