Notes
- Store leftovers covered in the fridge for up to 4 days. Reheat in the oven or microwave until warmed through. You can customize with sausage, bacon, ham, or vegetables like bell peppers and spinach. Using day-old bread or rolls helps the casserole soak up the custard better. This recipe can be made gluten-free by swapping the bread for a gluten-free variety. For best results, assemble at least 6 hours ahead or overnight before baking.
FAQs
Q1: Can I make it without meat?
Absolutely! Just skip the meat or replace it with sautéed veggies or plant-based sausage.
Q2: Can I use different bread?
Yes, French bread, sourdough, or even croissants work great for a richer flavor.
Q3: How do I know it’s fully cooked?
The center should be firm and not jiggly, and a knife inserted in the middle should come out clean.
