Recipe Guide

How can I make this dish vegetarian?

Substitute the pork sausage with plant-based sausage or omit it entirely and add extra vegetables such as mushrooms or spinach for added flavor and texture.

What type of bread works best in the casserole?

Day-old white or whole wheat bread cubes absorb the egg mixture well without becoming too soggy, providing structure and a pleasant texture.

Can I prepare this casserole ahead of time?

Yes, assemble the layered ingredients and refrigerate overnight. Bake just before serving for convenience without sacrificing taste.

Is it necessary to cook the sausage before layering?

Cooking the sausage beforehand ensures it’s fully browned, reduces excess fat, and enhances overall flavor in the finished dish.

What adds a smoky flavor to this dish?

A small amount of smoked paprika can be included in the egg mixture to introduce a subtle smoky note without overwhelming other flavors.

Can I use different cheese types?

While shredded cheddar is recommended for its melt and flavor, other cheeses like Monterey Jack or a mild gouda can be great alternatives.
