Sauteed Chicken Breasts with Creamy Chive Sauce

Ingredients

• 4 boneless, skinless chicken breasts (about 1 pound), trimmed of fat 
• 1 teaspoon kosher salt , divided 
• 1/4 cup plus 1 tablespoon all-purpose flour , divided 
• 3 teaspoons extra-virgin olive oil , divided 
• 2 large shallots , finely chopped 
• 1/2 cup dry white wine 
• 1 14-ounce can reduced-sodium chicken broth 
• 1/3 cup reduced-fat sour cream 
• 1 tablespoon Dijon mustard 
• 1/2 cup chopped chives (about 1 bunch)

Directions

1. Place chicken between sheets of plastic wrap and pound with a meat mallet or heavy skillet until flattened to an even thickness, about 1/2 inch. Season both sides of the chicken with 1/2 teaspoon salt. Place 1/4 cup flour in a shallow glass baking dish and dredge the chicken in it. Discard the excess flour.
2. Heat 2 teaspoons oil in a large nonstick skillet over medium-high heat. Add the chicken and cook until golden brown, 1 to 2 minutes per side. Transfer to a plate, cover and keep warm.
3. Heat the remaining 1 teaspoon oil in the pan over medium-high heat. Add shallots and cook, stirring constantly and scraping up any browned bits, until golden brown, 1 to 2 minutes. Sprinkle with the remaining 1 tablespoon flour; stir to coat. Add wine, broth and the remaining 1/2 teaspoon salt; bring to a boil, stirring often.
    
4. Return the chicken and any accumulated juices to the pan, reduce heat to a simmer, and cook until heated through and no longer pink in the center, about 6 minutes. Stir in sour cream and mustard until smooth; turn the chicken to coat with the sauce. Stir in chives and serve immediately.
