French Bread Quiche

This make-ahead quiche casserole swaps the fussy pastry crust for sliced French bread lining the bottom of a 9×13 pan. The bread soaks up the egg and cheese custard overnight in the fridge, so by morning you just slide it in the oven.

Two cheeses do the work here: Swiss for nutty depth and Monterey Jack for melt and stretch. A splash of white wine in the custard adds a subtle tang that cuts through all that richness. Crumbled sausage scattered over the top browns and crisps as the casserole bakes.

Assembling the night before isn’t just convenient, it’s actually better. The overnight soak lets the bread absorb every bit of the custard, so you get a uniform, silky texture throughout instead of dry spots.

Kitchen Tips

• Fill every gap in the bread layer with smaller pieces. Bare spots mean custard pools with no structure, and the casserole won’t slice cleanly.
• Keep the casserole covered with foil for the full bake to prevent the top from browning too fast while the center sets.
• Let it rest 10 minutes after baking before cutting. The custard firms up and slices hold together much better.

Variations

• Swap sausage for crumbled bacon or diced ham for a different smoky flavor.
• Add sauteed spinach and mushrooms to the custard for a vegetable-forward version.
• Use sharp cheddar in place of Monterey Jack for a bolder, tangier bite.
