HAM SWISS BREAKFAST CASSEROLE

We love doing breakfast for dinner or making this casserole when we have guests in town. It’s easy, cheesy, and full of flavor!Ham and Swiss Croissant Casserole slice

INGREDIENTScroissants

  • CROISSANTS – These can be found in the bakery or deli section of your grocery store. Crescent dough from the can cooked does not yield the same result.
  • HAM – I prefer a diced ham from a ham steak or cooked ham. I don’t love deli ham (like for sandwiches) as much but it can’t be used.
  • SWISS CHEESE – I love the flavor this gives the casserole but Gruyere, cheddar, or Monterey Jack cheese can be used.
  • EGGS
  • DIJON MUSTARD – This adds a special flavor and tang to the dish.
  • HALF AND HALF – You can use milk or all cream if you want.
  • GREEN ONIONS
