Within my family, I’m the self-proclaimed ‘queen of the egg sandwich.’ I think my husband and sons would concur, but you’d have to ask them to be sure.

That said, many months ago I had this idea to take my famous egg sandwiches over the top to fabulous, and I came up with an idea for this egg sandwich casserole. And, if I do say so myself, it’s pretty darned incredible!!

The ingredient list;

  • Bread
  • Eggs
  • American Cheese
  • Cheddar Cheese Slices
  • Shredded Cheddar Cheese
  • Bacon
  • Milk
  • Dijon Mustard
  • Salt and Pepper
  • Scallions 

Feeling extra cheesy?

With two kinds of cheese (American cheese slices and shredded cheddar) this egg sandwich breakfast casserole is extra cheesy and extra delicious.

But don’t be afraid to play around with the kinds of cheese you use.

I’m sure this would be just as delicious with Swiss, Jack, Colby, and maybe even cottage cheese stirred in with the egg mixture.

Don’t be afraid to get creative!

Can this egg sandwich casserole be made in advance?

Yes!

Make it up until the point where you’re ready to pop it into the oven.

Cover it well and refrigerate overnight.

Bake it off in the morning at 350-degrees for 60 minutes.

Yes!

After baking, cool completely.

To bake, uncover and bake in a preheated 350-degree oven for 90 minutes.

Cover, and continue baking until heated through (approximately 30 additional minutes).
