Ingredients

Scale
  • 12 slices white bread or 8 English muffins, cubed
  • 1 pound Canadian bacon or ham, chopped
  • 1 cup shredded Swiss cheese
  • 6 large eggs
  • 2 cups milk
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • For the Hollandaise: 4 egg yolks
  • 1/2 cup (1 stick) unsalted butter, melted
  • 1 tablespoon fresh lemon juice
  • Pinch of salt

Instructions

  1. Grease a 9×13 inch baking dish. Arrange half of the cubed bread or English muffins in an even layer on the bottom of the dish.
  2. Sprinkle half of the chopped Canadian bacon and half of the Swiss cheese over the bread layer. Repeat with the remaining bread, bacon, and cheese.
  3. In a large bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until combined.
  4. Pour the egg mixture evenly over the layered ingredients in the baking dish. Press down gently to submerge the bread.
  5. Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or preferably overnight.
  6. When ready to bake, preheat your oven to 350 degrees F (175 degrees C). Remove the plastic wrap.
  7. Bake for 45 to 55 minutes, or until the casserole is puffed, set in the center, and lightly golden brown.
  8. While the casserole bakes, prepare the Hollandaise: Place the egg yolks, lemon juice, and a pinch of salt in a blender. Blend on low speed.
  9. Slowly drizzle the hot melted butter into the blender while the blender runs on low speed until the sauce is thick and emulsified. Do not over-blend.
  10. Slice the casserole and serve immediately with a spoonful of the fresh Hollandaise sauce over each serving.

Notes

  • If you prefer a crispier top, uncover the casserole for the last 10 minutes of baking.
  • You can substitute regular ham for Canadian bacon if desired.
  • If the Hollandaise sauce separates, whisk in one teaspoon of warm water to try and bring it back together.
