Take an hour to whip this casserole up, and then freeze in individual portions so you can grab and microwave it at home or at the office for a quick and nourishing breakfast.

    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.

    I am not a big ‘make breakfast in the morning’ person, but I do get ravenous before lunch. So I’ve always had a love-hate relationship with breakfast. This is just so nutritious and delicious!

    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!

    I just made this and loved it! A great protein-filled meal that’s packed with veggies. I feel full and happy but not weighed down like I do after eating some other types of breakfast foods. I’m excited to add this to my list of favorite meals! ๐Ÿ™‚
