Scale

Main Ingredients

  • 6 slices of bread, cubed
  • 2 cups shredded cheese (cheddar or your choice)
  • 6 large eggs
  • 1 1/2 cups milk (whole or 2%)
  • Salt and pepper to taste
  • Optional: 1 teaspoon Dijon mustard or herbs for extra flavor

Instructions

  1. Prepare the Bread and Cheese: Cube the bread slices into bite-sized pieces and shred the cheese if not pre-shredded. Set aside.
  2. Assemble the Casserole: In a greased baking dish, layer half of the bread cubes evenly. Sprinkle half of the shredded cheese over the bread. Repeat layering with the remaining bread and cheese.
  3. Mix the Egg Mixture: In a medium bowl, whisk together the eggs, milk, salt, pepper, and optional mustard or herbs until well combined.
  4. Pour and Soak: Pour the egg and milk mixture evenly over the bread and cheese layers in the baking dish, pressing lightly to help absorb the liquid.
  5. Preheat the Oven: Set your oven to 350°F (175°C) and allow it to fully heat before baking.
  6. Bake the Casserole: Place the baking dish in the oven and bake for 35-40 minutes or until the casserole is set and the top is golden brown.
  7. Cool Slightly and Serve: Remove the casserole from the oven and let it cool for about 5 minutes before slicing and serving warm.

Notes

  • You can use any type of bread you prefer, including whole wheat or sourdough.
  • Feel free to add cooked bacon, sausage, or vegetables for a more substantial meal.
  • Use a blend of cheeses for more complex flavors.
  • Make ahead by assembling the night before and refrigerating, then bake in the morning.
  • Ensure the eggs are fully baked to avoid a runny center.
