Tips & Substitutions

For added flavor, consider using a mix of cheeses such as pepper jack for a spicy kick or gouda for a smoky flavor. You can substitute the sausage with turkey sausage or a plant-based alternative for a lighter option. If you prefer, replace the bread with croissants or bagels for a unique texture. Make sure to use day-old bread to absorb the custard mixture better.

Frequently Asked Questions

Can I prepare this casserole in advance?

Yes! This casserole is designed to be made the night before. After pouring the egg mixture over the sausage, cover it and refrigerate overnight. This allows the bread to soak up the flavors, making it even more delicious when baked.

What type of bread works best for this recipe?

Stale or day-old bread works best as it absorbs the egg mixture without becoming too soggy. French bread, sourdough, or even whole grain bread can all be excellent choices for added texture and flavor.

Can I add vegetables to the casserole?

Absolutely! Feel free to include sautéed bell peppers, spinach, or onions for added nutrition and flavor. Just make sure to cook them beforehand to avoid excess moisture in the casserole.
