Italian Chicken Cacciatore

Heat 2 tablespoons olive oil in a skillet over medium heat and cook onion, stirring often, until soft and translucent, about 5 minutes. Transfer to a pot.

Combine flour, 1/2 teaspoon salt, and 1/4 teaspoon pepper in a large bowl. Toss chicken thighs in the flour mixture until evenly coated.

Heat remaining 2 tablespoons olive oil in the skillet over medium heat, add chicken thighs, and brown on one side, without turning, for 5 minutes. Turn and cook until browned on the other side, about 5 minutes more. Transfer browned chicken thighs to the pot.
