01 - Pat the chicken breasts dry and season both sides with salt and pepper.
02 - In a large skillet, heat olive oil over medium-high heat. Sear chicken breasts for 5–6 minutes per side until golden and cooked through (internal temperature 165°F/74°C). Remove chicken and set aside, tented with foil.
03 - In the same skillet, reduce heat to medium. Add shallot and sauté for 2 minutes until softened.
04 - Add blueberries, thyme, chicken broth, balsamic vinegar, and honey. Simmer 5–7 minutes until blueberries burst and sauce reduces slightly.
05 - Stir in butter until smooth and glossy.
06 - Return the chicken to the skillet and coat with blueberry-thyme sauce. Simmer 1–2 minutes. Serve chicken topped with extra sauce and fresh thyme sprigs.
