Preheat the oven to 375°F.
Pat the chicken dry and season both sides with salt and pepper.
1 pound boneless, skinless chicken breasts, Kosher salt and freshly ground black pepper
Heat the olive oil in a large oven-safe skillet set over medium-high heat.
2 teaspoons olive oil
Sear both sides of the chicken until golden brown, about 2-4 minutes per side.
While the chicken sears, in a medium bowl whisk the honey, Dijon mustard, whole grain mustard, chicken broth, garlic, and thyme.
¼ cup honey, 2 tablespoons Dijon mustard, 2 tablespoons whole grain mustard, 3 tablespoons low-sodium chicken broth, 1 clove garlic, 1 teaspoon fresh thyme leaves
Pour the mustard sauce over the chicken and use a pastry brush to spread it out evenly over the chicken.
Bake for 15-25 minutes or until the chicken is cooked through. Smaller chicken breasts will cook faster, so start checking them earlier
