❓ 10 FAQs
Can I make this ahead of time?
Yes! Assemble it the night before, cover, and refrigerate. Just bake it in the morning.
Do I have to use bread?
Yes — bread helps absorb the egg mixture and gives structure. Use any hearty loaf.
Can I use uncooked sausage?
Pre-cook your sausage before adding to the casserole to ensure it’s fully cooked.
Is this kid-friendly?
Absolutely! You can make it mild and add their favorite veggies or cheeses.
Can I freeze individual portions?
Yes — slice and wrap each piece individually. Perfect for grab-and-go breakfasts.
What cheese melts best?
Cheddar, mozzarella, gouda, or a blend of your favorites work well.
Can I add eggs on top instead of mixing them in?
Not for this recipe — it’s designed as a strata, meaning eggs soak into the bread layers.
What’s the best bread to use?
Brioche, sourdough, or artisan-style loaves work best. Avoid thin sandwich bread.
Do I need to cover it while baking?
Bake uncovered unless it starts to brown too quickly — then tent loosely with foil.
Can I double the recipe?
Yes! Just use a larger baking dish (or two) and increase bake time as needed.
