Ham & Cheese Breakfast Casserole

A savory bread pudding built for brunch. Cubes of whole-wheat bread soak up a Dijon-spiked egg custard, while diced ham, wilted spinach, and jarred roasted red peppers layer in salt, green, and sweet. The Gruyere gets held back until the final 15 minutes so it melts into a browned crust on top instead of disappearing into the custard.

Covering the dish with foil for the first 40 to 45 minutes is the move. It lets the custard set gently without the top drying out before the eggs have a chance to cook through. Uncovering at the end is what gives you that puffy, golden top that makes a strata look like something worth photographing.

Swapping some whole eggs for egg whites keeps this lighter than the usual cream-heavy strata without losing the silky custard texture. Fresh rosemary is the secret weapon. Its piney note plays off the smoky ham beautifully.

Pro Tips

• Push the bread mixture down firmly to compact before baking. That ensures the custard soaks every cube evenly and the casserole holds its shape when sliced.
• Assemble the night before and refrigerate, then bake in the morning. Day-old soaking makes the texture even more silky.
• Let it rest 15 to 20 minutes after baking. The custard firms up and slices cleanly instead of spilling.
• Wilt the spinach first (squeeze out excess water) so the casserole doesn’t turn watery.

Variations

• Swap ham for cooked crumbled breakfast sausage or diced Canadian bacon.
• Use sharp cheddar or fontina in place of Gruyere.
• Add sauteed mushrooms or leeks for extra depth.
