Recipe Questions

Can I substitute turkey sausage for pork sausage?

Is it possible to add more vegetables to this dish?

Absolutely, chopped spinach or mushrooms can be added to boost the vegetable content and flavor complexity.

What is the best type of bread to use?

Day-old white or whole wheat bread cubes soak the custard nicely without becoming too soggy, providing ideal texture.

How can I ensure the casserole cooks evenly?

Even layering of sausage, vegetables, and bread, plus distributing the egg mixture well, helps achieve uniform cooking and set texture.
