Ingredients

  • 9 eggs
  • 3 cups milk
  • 2 teaspoons dijon mustard
  • 9 slices white bread torn into pieces
  • 1 pound diced ham
  • 1 small onion diced
  • 1 small green bell pepper diced, divided
  • 1 small red bell pepper diced, divided
  • 1 cup shredded cheddar cheese
  • 1 cup shredded pepperjack cheese
  • scallions for topping optional

Instructions

  • In a large bowl whisk together the eggs, milk, and dijon mustard.
  • Reserve a quarter of the diced red bell pepper and the green bell pepper. Set aside.
  • To the egg mixture stir in the bread, ham, onion, and diced peppers.
  • Butter or spray a 9x13 baking dish.
  • Pour the mixture into the dish.
  • Top with both types of cheese and the reserved bell peppers.
  • Cover with plastic wrap and place it in the fridge overnight or for up to 12 hours.
  • When ready to bake preheat the oven to 350 degrees.
  • Let the casserole sit on counter for 30 minutes to take the chill of while the oven preheats.
  • Bake the casserole at 350 for 55-60 minutes, you may need to cover it with foil if it begins to brown too quickly.
  • Remove from the oven and serve!
  • Top with scallions when serving if desired.

Notes

  • Store leftovers in the fridge for up to 5 days.
  • You can swap out the meat in this dish, try it with cooked sausage or bacon!
  • You can spice this up by adding diced jalapenos or diced green chiles.
  • Use whatever cheese you like, swiss would be great.
  • I use sandwich bread but any kind of bread would be great, croissants would work, Italian bread, brioche or you can even add more than one kind of bread - but keep in mind that some of them will absorb more of the liquid or less - so the final result could be either dryer or moister than this original recipe!
