Are you looking for an easy breakfast casserole to feed a crowd that doesn’t keep you in the kitchen? This recipe is like the whole breakfast in a pan—fluffy eggs, gooey cheese, bread, and a side of savory sausage that loads the whole dish with flavor. And the best part is, it only takes a few minutes to assemble the night before and you can bake it while you’re hanging out with a cup of coffee the next morning!
Years ago this breakfast casserole became as much of a Christmas morning tradition in my family as opening presents in our PJs. We quickly put it together before bed on Christmas Eve and bake it while we open presents. For our big, hungry crew we make two disposable aluminum pans full. When it’s ready, we break for food to fuel up before going back in for the second half (we open one at a time so it’s a marathon).
Ingredients for Sausage and Egg Breakfast Casserole.
This easy recipe only takes five simple ingredients and some seasoning:
- 6 slices of bread
- 1 lb. pork breakfast sausage
- 2 cups shredded cheddar cheese
- 8 eggs, beaten
- 2 cups milk
- 1 tsp. salt
- Black pepper to taste
How to Make Sausage, Egg, and Cheese Breakfast Casserole.
- Brown the sausage over medium heat in a large skillet. Drain the excess grease if needed (usually there isn’t enough to worry about).
- Grease a 9×13 casserole dish or large baking dish. Cube the bread and lay it in the bottom of the pan.
- Spread the sausage crumbles over the bread cubes.
- Then sprinkle the cheese over the top.
- In a large bowl, beat the eggs with a wire whisk. Then mix in the milk, salt, and pepper.
- Pour the egg mixture over the other ingredients in the pan and cover it with plastic wrap or aluminum foil.
- Pop it into the refrigerator overnight to let the bread soak up the liquid.
- The next day, preheat the oven to 325 degrees.
- Remove the casserole from the refrigerator and let it sit at room temperature for 20 minutes before baking. (Never put very cold glassware in a hot oven or it may shatter)
- Uncover the pan and bake for 45 minutes or until set. Time will vary depending on how cold it is going in, your oven, and what kind of pan you use. Insert a knife in the center to check—it should come out clean when done.
- Cut it into squares right in the pan to serve.
Options and Modifications.
Although having only five ingredients make this easy casserole fast, there’s so much potential to switch things up from this basic dish.
- Add color and more flavor with green onions or some green or red bell pepper.
- Add veggies like broccoli, asparagus, and mushrooms.
- Make it Mexican with a little bit of taco seasoning, green chiles, and Mexican blend cheese. Serve with some salsa.
- For extra fluffy eggs, add 4 tbs. of sour cream or yogurt. Or replace some or all of the milk with heavy cream or half and half.
- Change the amount of cheese. We like it extra cheesy so I use the full bag of 2 cups of cheese.
- Change the bread. I’ve always used white bread because that’s what most of my family likes. But you could just as well use wheat bread, french bread, biscuits, or whatever you might have (it may change your bread/egg ratio and consistency). You can also butter the bread before cubing.
- Or make it low carb by omitting the bread altogether. It will really be more like an omelette in a casserole dish, but it won’t require sitting overnight.
What to Serve with Egg and Sausage Breakfast Casserole.
This perfect breakfast casserole covers a lot of the basic breakfast foods. But this savory dish pairs well with something sweet like fresh fruit or my other easy go-to breakfast for a crowd, cinnamon roll monkey bread or air fryer biscuit beignets.
Storage and Reheating Leftovers.
- To save the leftovers, cover them with plastic wrap, foil, or in an airtight container in the refrigerator for up to five days.
- To reheat, zap individual pieces in the microwave at 50 percent. Start at 30 seconds and add time as needed.

Looking for a breakfast casserole recipe that includes hash browns, ham and cheese.
Thanks 🎄
I don’t have one, but maybe someone can share a good one with us in the comments?
Just use this one and use those ingredients instead of the sausage. Put the hashbrowns on the bottom, add the ham and cheese, then pour the eggs on top.
I made this for my husband’s bible study group and it was a hit! Wouldn’t change a thing about the recipe, except maybe using my homemade bread instead of store-bought. Definitely will make again, and soon!
Thanks Kate, I now have my Christmas morning meal planned.
Merry Christmas,
I used to make a very similar casserole years ago that used crescent rolls as the bottom crust, and I think only 6 eggs. So good….and I had kind of forgotten about it until your post, so thanks for the reminder! Great with just coffee, juice and maybe some fruit. We’ve even had it for dinner!
We’ll eat this one for any meal too. I need to try the crescent roll one – I’m sure we’d love it!
