  • For a richer flavor, use bone in, skin on chicken thighs instead of chicken breasts. Just remember to remove the bones and skin after cooking.
  • Don’t overcook the chicken! It will become dry and tough.
  • If you don’t have Ritz crackers, you can use any type of cracker or breadcrumb for the topping. Try different toppings to find your favorite!
  • Add a splash of white wine to the sauce for added depth of flavor.
