Eggs in a wooden bowl, mini croissants in a wooden tray, and milk in a glass measuring cup on a gray board.
  • Bread: The star of the show! Croissants, baguettes, sourdough, brioche, or even sandwich bread – all work beautifully. Stale bread is ideal.
  • Eggs: Use approximately one egg per cup of bread for the perfect custard consistency.
  • Milk: Whole milk provides richness, but a mixture of heavy cream and whole milk elevates the flavor even further.
  • Seasoning: Simple yet essential – salt, pepper, and garlic powder enhance the savory notes.
  • Add-ins: This is where you can get creative! Ham, cheese, cooked sausage, bacon, vegetables – the possibilities are endless.

  • Bake: Bake the casserole until the egg mixture is set and the top is golden brown and crispy.

Anna’s Expert Tips for the Best Bread and Egg Casserole

Having perfected this casserole over numerous iterations, I’ve gathered a few key tips to help you achieve the best results:

  • Cream It Up: For an extra-rich and decadent flavor, use a combination of milk and heavy cream. Half-and-half also works well.
  • Soak it Right: The drier the bread, the more soaking time it requires. While croissants typically don’t need pre-soaking, heartier breads like sourdough benefit from soaking in the egg mixture for several hours, or even overnight, before baking. This ensures a moist and tender casserole.
  • Flavor Fiesta: Don’t be afraid to experiment with flavor! Ham and cheese are classic additions, but cooked breakfast sausage or bacon, sautéed onions and peppers, or even shredded chicken can create exciting variations.
  • Center Check: Even if the baking time is complete, always check the center of the casserole to ensure the egg mixture is fully set. If it’s still runny, continue baking for a few more minutes.
  • Cover Up: For the first 20 minutes of baking, cover the casserole with aluminum foil or a lid. This prevents the bread from browning too quickly while allowing the center to cook evenly. This is especially helpful when using croissants, which tend to brown rapidly.
