Breakfast Casserole with Bread Recipe

If you’re like me, you’re a big fan of breakfast casseroles. I mean, what’s not to like? They are essentially an all-in-one meal that can be tailored to your family’s tastes. Here on All Things Mamma, I have breakfast casseroles with potatoes, breakfast casseroles with crescent roll crusts, and even breakfast casseroles for the slow cooker. But this breakfast casserole with bread is my current fave!

The recipe is very similar to a French toast casserole, except instead of sweet flavors, it leans savory with cheese and sausage. You can feel free to swap the sausage for ham, bacon (Canadian or otherwise), or even roasted veggies for a meatless breakfast bake.

How to Make Sausage & Egg Breakfast Casserole With Bread

1. Prepare

Grease a 9×13 baking dish with butter or cooking spray.

2. Cook the Sausage

In a heavy skillet, cook the sausage with a little vegetable oil. Break up the sausage with a wooden spoon while it cooks. Once it is cooked through and browned, remove it from the pan.

3. Cook the Onion

In the same skillet, cook the onion until it’s translucent, which should take about 4 to 5 minutes. Remove the onion from the pan and set it aside.

4. Assemble

In a large mixing bowl, whisk the eggs, half of the cheese, milk, and seasoning. Fold in the toasted bread, sausage, and onions. Pour this mixture into the prepared baking dish. Top with the remaining cheese, then cover the dish and refrigerate it for at least 8 hours or preferably overnight.

5. Bake

Let the casserole come to room temperature while the oven preheats to 350ºF. Bake, uncovered, for 40 to 50 minutes. The casserole is done when a cake tester comes out clean.

How to Store and Reheat Leftover Breakfast Casserole With Bread

Store any leftovers wrapped in the baking dish or transfer them to an airtight container. Refrigerate for up to 3 days and reheat in a 350ºF oven or in the microwave until warmed through. This breakfast casserole can also be frozen for up to 2 months; let it thaw in the refrigerator before reheating.

FAQ

What goes with breakfast casserole?

I like serving this breakfast casserole with bread alongside fresh fruit for an easy breakfast! If you’re making it for a crowd, you might want to also make a sweet breakfast recipe like my Easy Cinnamon Roll French Toast Casserole so everyone can choose whether they want a sweet breakfast, savory, or a little of both!

How long can uncooked breakfast casserole stay in the fridge?

I don’t recommend letting this sit in the fridge longer than overnight. If it sits too long, the bread will get too soggy.

What can I put in breakfast casserole with bread?

Leftover ham (I use the ham from my Crock Pot Ham), crumbled bacon, or Canadian bacon are all great additions, as are roasted broccoli or sautéed mushrooms. Feel free to get creative with this recipe!

    Why are we preheating the oven if we’re going to leave it in the fridge overnight? Just wondering. I’m still going to try it, but I won’t preheat till I’m ready to bake it lol

    I think there was too much milk to the eggs, and I ended up having to cook it for far longer than what was listed. It ended up tasting like really wet scrambled eggs and cheese.
