Beef and Cheddar Breakfast Casserole is the ultimate comfort food for mornings when you need something hearty, satisfying, and full of bold flavor. This all-in-one breakfast bake combines seasoned ground beef, sharp cheddar cheese, fluffy eggs, and bread cubes to create a savory dish that’s easy to prepare and always a hit with family and guests.
At its core, the casserole features a base of cubed bread, day-old or toasted works best, which soaks up a mixture of beaten eggs and milk, forming a creamy, quiche-like texture. Browned ground beef, often seasoned with onions, garlic, salt, and pepper, adds protein and richness. The cheddar cheese brings a sharp, melty element that pairs perfectly with the beef, adding depth and creaminess to every bite.
Optional ingredients like diced bell peppers, green onions, or even a dash of hot sauce can be added for extra flavor and texture. Once assembled, the casserole is baked until golden on top and cooked through in the center, creating a dish that’s as comforting as it is convenient.
One of the biggest advantages of this breakfast casserole is that it can be prepared the night before and baked in the morning, making it ideal for busy weekdays, holidays, or brunch gatherings. It also reheats well, so leftovers can easily be enjoyed the next day.
Serve it on its own or with a side of fresh fruit, hash browns, or toast for a complete breakfast. Whether you’re feeding a crowd or just want something filling and delicious to start your day, Beef and Cheddar Breakfast Casserole checks all the boxes.

Not enough flavor for me. Maybe add more spices next time.
The eggs made it too watery. I followed the recipe exactly and it was all mushy!
Sounds like you might have added too much milk or eggs. They can make it soggy! Next time, maybe try reducing one of those? Just a thought!
It was ok, but I felt like it needed something else…maybe some more spices?
Me & my kids loved it!! Even my picky eater tried it!
That’s awesome! It’s always a win when picky eaters try something new. Mine loved it too!
Looks good, but my kids would never touch that. They are so fussy!
This recipe is amazing! It tastes so good and my family loved it.
Casserole? I thought it was a sandwich, lol! Anyway, looks easy.
I followed the recipe but it came out too soggy, any tips?
Never thought beef for breakfast! But wow, this is delicious. Gonna make it again.
Sounds good! But can I use turkey instead of beef?
Ah, forgot the paprika! It didn’t taste right. 🙁
Why is there so much cheese? It was too cheesy for my liking.
Good but took way too long to bake! 35-40 mins felt like forever.
I didn’t have some spices, but I used hot sauce instead and it turned out great!
That’s awesome! Hot sauce adds a nice kick! My family loved it too.
But hot sauce instead of spices? Isn’t that too spicy? I don’t think that would work for everyone.
This was awesome! My kids loved it!
Yum!! Cheese overload, just how I like it!
