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!

INGREDIENTS

• 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

HOW TO MAKE THIS

• 1. Grease a 9×13 baking dish. Layer half the croissants, half the ham, and half the cheese. Repeat layers.
  2. In a large bowl, whisk together the eggs, half and half, green onions, mustard, salt, and pepper.
  3. Pour mixture over the croissant mixture making sure it is all covered. Cover with foil and refrigerate for at least 8 hours or overnight.
  4. 
     When ready to bake, remove casserole from fridge and let sit at room temperature while the oven preheats. Preheat oven to 350 degrees. Bake covered for 30 minutes. Remove foil and bake another 25-35 minutes or until top is browned and the center is set. Eat warm. Garnish with more green onions if desired.
