1Season the chicken thighs with salt and pepper and let them rest.
2Mince one of the garlic cloves and set it aside for later.
3In a large, ovenproof skillet over medium-high heat, add the oil.
4When the oil is hot, add the 5 smashed whole garlic cloves, the anchovies, capers and chile.
5Let cook, stirring with a wooden spoon to break up the anchovies, until the garlic browns around the edges and the anchovies dissolve, 3 to 5 minutes.
6Add the chicken thighs and cook until nicely browned on one side, 5 to 7 minutes.
7Flip the thighs, place the pan in the oven, and cook another 5 to 10 minutes, until the chicken is cooked through.
8When chicken is done, transfer thighs to a plate (be careful, as the pan handle will be hot).
9Place skillet back on the heat and add minced garlic and the juice of one lemon half.
10Cook for about 30 seconds, scraping up the browned bits on the bottom of the pan.
11Return chicken to the pan and cook it in the sauce for another 15 to 30 seconds.
12Transfer everything to a serving platter.
13Squeeze the remaining lemon half over the chicken and garnish with chopped parsley.
