- 4 boneless, skinless chicken breasts, trimmed
- Salt and freshly ground pepper
- 1 tablespoon extra-virgin olive oil, divided
- 1/4 cup finely chopped shallots
- 1/4 teaspoon crushed red pepper
- 1/2 cup reduced-sodium chicken broth
- 1/2 cup ruby-red grapefruit juice
- 2 tablespoons chopped fresh mint, divided
- 2 teaspoons all-purpose flour
- Season chicken on both sides with salt and pepper. Heat 1 1/2 teaspoons oil in a large heavy skillet over medium-high heat. Add the chicken and sear until well browned, about 3 minutes per side. Transfer the chicken to a plate and tent with foil.
- Reduce heat to medium. Add the remaining 1 1/2 teaspoons oil to the pan. Add shallots and red pepper. Cook, stirring, for about 2 minutes. Remove from heat. Whisk broth, grapefruit juice, 1 tablespoon mint and flour in a small bowl. Add to the pan. Cook, whisking, until slightly thickened, about 3 minutes.
- Return the chicken and any accumulated juices to the pan; reduce heat to low. Simmer until the chicken is cooked through, about 4 minutes. Transfer the chicken to a warmed platter. Season the sauce with salt and pepper and spoon over the chicken. Garnish with the remaining 1 tablespoon mint.
