Heat oil in a medium frying pan over medium-high heat. Add chicken and cook until lightly browned, about 5 minutes, then turn over and cook an additional 5 minutes. Transfer chicken to a plate and set aside.
Uncover, increase heat to medium-low and cook 15 to 20 minutes more, occasionally spooning sauce over chicken, until sauce thickens a bit and chicken is tender and nicely glazed with sauce. Remove bay leaf.
