Christmas Morning Breakfast

I love Christmas morning! The kids waking up and being so excited to open their gifts is one of the most special times of the year. But lets get real, who likes to interrupt the fun to make breakfast?

Not me! That’s why I rely on make-ahead breakfasts like this Christmas morning casserole—so I can spend more time with family instead of cooking in the kitchen!

Make-Ahead Christmas Breakfast: Easy Overnight Casserole Recipe

This year, I’m ahead of the game with the absolute best Christmas morning casserole planned! This breakfast casserole recipe uses all the essentials: eggs, milk, cheese, bread, and your choice of protein. It’s perfect whether you’re making it fresh in the morning or prepping it the night before to pop it in the oven on Christmas morning.

This Christmas casserole really is so yummy and my entire family loves it! That in itself is a Christmas miracle!

For my family of five, I half the recipe and baked it in a 9″ square pan but you can double the recipe (listed below) to fill a 9×13 pan to feed a large crowd or to have more to munch on while opening gifts! Make sure to serve the casserole in a pretty casserole dish!

The Best Holiday Breakfast for Hosting Guests

Because my family loves this extra special recipe so much, I actually make it all throughout the year, particularly on weekends for breakfast or brunch. It also works great for when we have guests in from out-of-town staying the night. I ALWAYS make this because:

  • it’s so easy (who wants to be slaving away in the kitchen while all of your guests enjoy themselves??)
  • doesn’t cost a fortune and goes a long way
  • most importantly, it only requires very simple ingredients that I always have on hand! Since I’m not one to plan ahead, this comes to my rescue every time!!

This dish is perfect for Christmas morning, Easter brunch, or a special weekend breakfast. It’s also a great choice for Mother’s Day and Father’s Day! You can even switch it up with different mix-ins like bell peppers or hash browns to give it a new twist each time!

Customizing Your Christmas Breakfast Casserole: Sausage, Bacon & More

My original recipe calls for ground sausage (our favorite is Jimmy Dean Original sausage), but if you don’t have any on hand, I’ve swapped out the sausage for bacon! You can also add bell peppers for extra flavor. Just be sure to season with salt and pepper to bring out the best taste in your casserole.

💡 Pro Tip: Pre-cook your bacon before adding it to the egg/milk mixture!

  • Pour into a greased 9×13 inch baking dish and sprinkle on the remaining 1/4 of cheese.

Bake Immediately or Chill in Refrigerator

  • Cover, and chill in the refrigerator for 8 hours, or overnight OR bake immediately in a 350° oven.
  • Cover, and bake 45 to 60 minutes. Uncover, and reduce temperature to 325° F Bake for an additional 30 minutes, or until set.

Notes

💡 Pro Tips!
1️⃣ Prep Ahead – Assemble the night before and chill overnight in the refrigerator for a stress-free morning.
2️⃣ Use Day-Old Bread – Slightly stale bread absorbs the egg mixture better for a fluffier texture.
3️⃣ Cook Meat First – Fully cook sausage, bacon, or ham to prevent excess grease and enhance flavor.
4️⃣ Whisk Well – Beat eggs and milk thoroughly with salt and pepper for a smooth, airy texture.
5️⃣ Don’t Skip Cheese – Use a mix of cheddar, mozzarella, or gouda for a rich, melty bite.
6️⃣ Add Veggies – Sautéed bell peppers, onions, or spinach boost flavor and nutrition.
7️⃣ Bake Until Golden – The top should be crispy, and a toothpick should come out clean when inserted.
8️⃣ Let It Rest – Allow 5-10 minutes before slicing to help the casserole set.
9️⃣ Pair with Sweets – Serve with cinnamon rolls, fruit, or French toast for a balanced holiday meal.
🔟 Make More for a Crowd – Double the recipe in a 9×13 pan or bake two casseroles.
