Seared Chicken Breasts with Lemon and Chive Sauce

Ingredients

Chicken

•     4 boneless, skinless chicken breasts (6-8 ounces each)
•     2 teaspoons kosher salt
•     1 tablespoon vegetable oil
•     2 tablespoons unsalted butter, melted
•     1 tablespoon all-purpose flour
•     1 teaspoon cornstarch
•     1/2 teaspoon ground black pepper

Sauce

•     1 medium shallot, minced
•     1 teaspoon all-purpose flour
•     1 cup low-sodium chicken broth
•     1 tablespoon lemon juice
•     1 tablespoon minced fresh chives
•     1 tablespoon unsalted butter, chilled
•     salt & pepper

Preparation

1. Preheat the oven to 275 degrees and adjust the oven rack to lower-middle position.  Using a fork, poke the thickest part of each chicken breast 5 to 6 times.  Sprinkle the breasts evenly with 1/2 teaspoon of kosher salt.  Places the chicken breasts in a 9×13-inch baking dish and cover tightly with foil.  Bake until the thickest part of the breast registers 145 to 150 degrees on an instant read thermometer – around 30-40 minutes depending on the thickness of the breasts.
2. Remove the chicken from the oven and transfer to a plate lined with paper towels and pat dry.  Heat oil in a 12-inch skillet over medium high heat until smoking.  While the pan is heating, whisk the butter, flour, cornstarch, and pepper together in a small bowl.  Lightly brush the top side of the breasts with half the butter mixture.  Place the chicken in the skillet (butter side down) and cook until browned, about 3-4 minutes.  While the chicken browns, brush the chicken with the remaining butter mixture.  Using tongs, flip the chicken, reduce heat to medium, and cook until the second side is browned and the thickest part of the breast registers 160-165.  Transfer the chicken to a plate and let rest while making the pan sauce.  If you are not making a sauce, let the chicken rest for 5 minutes anyway before serving.
3. Add shallot to the skillet and cook over medium heat until softened about 3-4 minutes.  Add flour and stir constantly – around 30 seconds.  Add broth and increase heat to medium high, and bring to a simmer, scraping up the brown bits on the bottom of the pan.  Simmer rapidly until reduced to about 3/4 of a cup, 3-5 minutes.  Stir in any accumulated juices from the plate holding the chicken, and return to simmer and cook 30 seconds more.  Turn off the heat, and whisk in the lemon juice, chives and butter.  Season with salt and pepper.  Spoon over chicken and serve immediately.
