Season chicken breasts with salt and pepper. Heat olive oil in a skillet over medium-high heat.
Sear chicken on both sides until golden brown (about 4–5 minutes per side). Remove and set aside.
In the same skillet, add apple cider, Dijon mustard, and maple syrup. Stir and bring to a simmer.
Return chicken to the pan, reduce heat to medium-low, and cook for 10–12 minutes until chicken is fully cooked and glaze thickens.
Spoon glaze over chicken before serving and garnish with fresh rosemary or thyme.
