Season the chicken breasts with salt, pepper, and Italian seasoning.
Place the flour in a shallow dish, and dredge the chicken pieces in the flour. Shake off any excess flour.
Heat the olive oil in a large skillet over medium-high heat and brown the chicken breasts for 4 minutes on each side until golden brown and fully cooked. Transfer to a plate and keep warm.
Pour the chicken broth into the skillet and scrape up any bits and pieces of chicken stuck to the bottom. Mix in the onion powder, garlic powder, basil, oregano, mustard powder, and dried parsley. Bring to a boil and cook for 1 minute.
Reduce the heat to medium-low and add the cream of chicken soup, sour cream, milk, and lemon juice. Return the chicken breasts to the skillet, cover with the sauce, and cook for 2-3 minutes until heated through.
