Common Questions

Can I bake it right away instead of overnight? Yes, but the bread won't absorb the egg mixture as well. Let sit at least 30 minutes before baking.

Why is my casserole watery?

• Too much milk in ratio
• Didn't bake long enough
• Didn't let rest before serving
• Vegetables released water (drain them first)

How do I know when it's done?

• Center should be set (not jiggly)
• Knife inserted comes out clean
• Internal temperature: 160°F
• Edges pulling away from pan slightly

Can I use different types of bread? Absolutely! Try:

• Brioche (rich and sweet)
• Challah (fluffy and light)
• Sourdough (tangy)
• Whole wheat (hearty)
• Croissants (buttery)
