  • 2 cups shredded Swiss cheese
  • 1 can (10.5 oz) cream of chicken soup

Notes

  • Use rotisserie chicken for convenience.
  • For a low-carb option, replace breadcrumbs with crushed pork rinds.
  • Make ahead: Assemble and refrigerate for up to 24 hours before baking.
  • Freeze before baking for up to 2 months; thaw overnight before cooking.
  • Add Gruyère or mozzarella for a creamier texture.
