12 Christmas Casseroles Big Enough to Feed a Full House

Hosting a full house during the holidays is equal parts joyful and demanding, especially when it comes to feeding everyone well. These meals can be assembled ahead, baked all at once, and served warm over long stretches, which is exactly what busy holiday mornings and crowded dinners require. From hearty breakfast casseroles to rich, savory mains and classic sides, these dishes focus on generous portions, dependable flavors, and stress-free serving. They are built to satisfy different tastes and appetites while letting hosts spend less time in the kitchen and more time enjoying the celebration.

1. Classic Christmas Morning Breakfast Casserole

This casserole is a holiday staple because it solves the biggest Christmas morning problem: feeding a crowd without standing at the stove.
