Let's cook
Use stale bread
Day-old or oven-dried bread cubes soak up the custard without collapsing. Fresh bread turns to paste.
💡If your bread is fresh, dry the cubes at 300°F for 10 minutes.
Brown the sausage and vegetables
Cook the sausage until browned, then the onion and pepper for 5 minutes. Drain off excess fat.
Layer
Spread half the bread in a greased dish, then half the sausage mixture and cheese. Repeat.
Pour the custard over
Whisk the eggs, milk, mustard, nutmeg, salt, and pepper and pour evenly over the whole dish. Press down so every cube is submerged.
Rest overnight
Cover and refrigerate at least 4 hours, ideally overnight. This is what lets the bread absorb the custard fully.
💡The overnight soak is the entire point. A quick assembly bakes into dry bread with egg around it.
Bake from cold
Bake uncovered at 350°F (175°C) for 55–65 minutes until puffed, golden, and set at the centre. Rest 10 minutes before cutting.

📝 Tips, swaps, and make-ahead notes
Take it out of the fridge 30 minutes before baking so it heats evenly. If the top browns before the centre sets, tent with foil. A knife inserted in the middle should come out clean.
- •Vegetarian: Mushrooms and spinach in place of the sausage; squeeze the spinach dry.
- •Freezer: Freeze assembled and unbaked for 2 months; thaw overnight and bake as normal.
- •Croissant version: Use torn croissants instead of bread for something much richer.
