Brown the seasoned chicken breasts in the skillet for 5-6 minutes on each side until golden brown.
Add the bite-sized potato chunks to the skillet and stir to combine.
Create the sauce by pouring in the chicken stock, cream, Dijon mustard, and lemon juice. Simmer for 15-20 minutes until chicken is cooked and potatoes are tender.
Season to taste with additional salt and pepper before serving.
Notes
Pair with a light green salad or roasted vegetables. Crusty bread is great for soaking up the sauce.
