I absolutely love make-ahead dishes, especially when company is in town. My Overnight Omelette Breakfast Casserole is a perfect example of getting the mess out of the way the day before your meal. In the morning, just pop it in the oven and breakfast is served!
This is another recipe re-do. I originally made it at Thanksgiving time, when I had extra mouths to feed (aka Josh). So now that he’s home for the summer and getting up REALLY early to work-out before his internship, I thought it was time to make it again. He’ll love having a piece of this protein/veggie packed dish to warm up before he gets to work.
And just so you know, I made this in two separate dishes this time around. (So my pictures only show one dish.) But making it in a 9×13 pan is best.
If ya’ll have ever made omelettes for a group, and realized that all you did was cook while everybody else was eating, this casserole is for you.
- You simply make it the night before your breakfast.
- Store it in the refrigerator overnight.
- And then pop it in the oven about an hour before you eat.
Steps to make an epic overnight omelette casserole:
- Lay out the bread in the casserole dish, butter side down.
- Cook the meat, and layer it on top of the bread.
- Sauté the veggies, and layer them on top of the meat.
- Whip up the egg mixture, and pour on top of the the veggie layer.
- Top with cheese, cover, and store overnight.
- Wake up the next morning, and BAKE.
Use a bunch of veggies to boost the healthy.
- bell pepper
For the meat, I used a spicy sausage and bacon. But you could swap these for ham or even leave it out and enjoy a meatless casserole. Whatever you like best is what you should use.

- Use your choice of meat for this casserole. You can even skip it for a meatless dish.
- The veggies can be substituted as well, for whatever you like best.
