Breakfast casseroles are great for entertaining, too – I love to make them for brunch and serve it with a baked ham and mimosas or bloodys. This would be great for Easter!

Great recipe! I also eat breakfast every day, usually about 1-2 hours after i get up. It’s a must to get me energized (I mean, besides coffee). I’m not a fan of breakfast sausage, but feel like this would be great with some chicken sausage.

ya, that’s what I used & it was great.

Claire | Sprinkles and Sprouts says
I admit to not being a breakfast eater. I am a late riser!
I get up at 7 and have the kids out of the door for school before 8.
I spend 30 minutes cleaning the house, then I sit down to breakfast and a cup of coffee. Usually catching up on emails.
But this casserole, it sounds delicious and I can see myself having it in the fridge to pick at, after a big brunch party!
Rebecca says
Hi Claire, haha when you do get hungry in the morning, this could be a great option!
Abbey Sharp says
Breakfast in casserole form should ALWAYS be a thing. I would totally batch cook this for lunch too!
