A creamy, custardy breakfast casserole with sausage, three types of cheese, and day-old bread, baked to golden perfection. Perfect for holiday mornings, brunch with friends, or any day you want to start with something memorable.
For best texture, use day-old bread and let the assembled casserole rest in the fridge for at least 1 hour. Room temperature eggs incorporate more smoothly. Blend cottage cheese until smooth for a creamy custard. Do not overbake; the center should be just set with a slight jiggle. Leftovers keep in the refrigerator for up to 4 days and freeze well for up to 2 months.
