Why We Love It!

Christmas morning is filled with activity and fun, so who wants to step away from the magic to make breakfast?

That is why I LOVE whipping up a tasty breakfast casserole the night before.

Here’s why we especially love this casserole for Christmas:

  • Made ahead. I can prep the night before and on Christmas morning, I simply pop it in the oven and return to the fun!
  • Flavorful, Filling + Customizable. It has savory sausage, filling bread, and creamy eggs (and easy to change up the meat, veggies and cheeses).
  • Flexible. Though handy, it does not need to be made the night before, as long as you do give it some time to chill.

It would be a perfect compliment to our French Toast Casserole for both a sweet and savory option.

Ingredients

  • ground pork sausage or maple sausage or cubed ham
  • salt
  • eggs
  • half and half – or use 1 cup of whole milk
  • white bread toasted and cut into cubes (or use challah, French Bread, brioche, or Texas toast)
  • sharp cheddar cheese You can also use Swiss, mozzarella, or colby jack.

Prep for the Morning

  1. PREP. Grease a 9×13-inch baking dish, and set aside.
  2. SAUSAGE. In a skillet, cook the sausage over medium heat until browned, and drain.
  3. MIX. In a medium bowl, mix the salt, eggs, and half and half. Add the sausage, bread cubes, and cheese. Stir together until evenly coated. Pour the mixture into the baking dish.
  4. CHILL. Cover with aluminum foil and chill in the refrigerator for at least 2 hours, or overnight.
  5. BAKE. Preheat the oven to 350°F. Bake the casserole, covered, for 50-60 minutes. Reduce the heat to 325°F. Uncover the casserole and bake for 20-30 additional minutes or until the casserole has set.

Pro Tip

Some may worry that soaking too long will result in the casserole being soggy. One trick is to use stale bread. To help your bread dry out a little faster, pop it in the oven for 8-10 minutes at 350°F.

Variations

  • Meat. Add crumbled bacon to the top or add a mix of meats.
  • Add veggies. Broccoli florets, artichokes, asparagus, sautéed mushrooms, diced red and green bell peppers, and green onions (in the mix, or on top)
  • Add heat. Spicy sausage, red peppers, jalapeños, or top with hot sauce

storing Info

  • FREEZE. To prepare your easy Christmas breakfast further in advance than overnight, cover the dish with plastic wrap and again with foil. Label and freeze for 1-2 months. Thaw in the fridge before removing the wrappings and baking. 
  • Store leftovers. Divide into individual-sized storage containers. Keep in the fridge for 3-4 days, or in the freezer for 2-3 months. Thaw, if applicable, and reheat in the microwave or oven.

    I made this for Christmas breakfast yesterday along with the French Toast casserole and both were a hit! I prepped everything the night before EXCEPT- I used toasted English Muffins cut in cubes and mixed them in just before baking. I also used 1/2 cheddar and 1/2 Jack cheeses, and put some diced red and green bell peppers on top (also mixed some
    in) to make it more “Christmassy”. Served with Siracha and OMG it was sooo good. My family wants it every year! It was perfect with the French Toast Casserole… try them both!

    Super yummy. I subbed gluten-free bread and added some garlic and onion powder. I’ll be making this again next Christmas too!

    Made it for Christmas 2021 for my son’s family. It was a hit with all 7 of us. Includes toast cubes, sausage, cream, eggs and cheese. What’s not to like.

    Delicious! We ate today on Christmas! Two make ahead Christmas casseroles were my Christmas present to myself. Usually I make a big breakfast after we open gifts, but I decided to cook ahead this year. My husband wasn’t thrilled but ended up loving this! I used leftover sourdough bread and added some diced onion – so good. Oh, and my mom was with us and doesn’t eat cheese so I split some into another pan – it was really ggod that way too. I think part of the key is cooking it for so long – the browned edges were my favorite. Keeping this one – it was a hit!
