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.
