This recipe outlines a make-ahead ham and cheese breakfast bake, perfect for entertaining or a leisurely morning. Layers of thinly sliced baguette, savory ham, and sharp Cheddar are soaked in a rich egg and milk custard, then baked until golden and bubbling. Prepare it up to 24 hours in advance for maximum flavor absorption.
This breakfast bake truly benefits from the advance preparation, allowing the baguette to fully absorb the custardy egg mixture, leading to a more cohesive and flavorful dish. For best results, use a baguette that's a day old or slightly stale; fresh bread can become overly soggy. Don't be shy with the Dijon mustard; it provides a crucial tang that cuts through the richness of the ham and cheese. Consider adding a pinch of freshly grated nutmeg to the egg mixture for an extra layer of warmth and complexity. When baking, ensure the center is fully set – a skewer inserted should come out clean, or an internal temperature of 160°F (71°C) indicates doneness. If the top browns too quickly, cover loosely with foil.
