Egg Sandwich Breakfast Casserole

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!!

Easy Egg Sandwich Casserole Recipe

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!

A Serving of Egg Sandwich Casserole

Follow these easy step-by-step photos to make your own egg sandwich casserole. It really couldn’t be any simpler, or straight forward, to make…

Toast 8 slices of bread (I used Pepperidge Farm Hearty White) and lay four of them in the bottom of an 9×13 baking dish. Top each slice of toast with two slices of American cheese. Fry four eggs to over hard consistency and season them with salt and pepper.

How to make egg sandwich casserole

Place the fried eggs on top of the toast and American cheese slices and top the eggs with more two more slices of American cheese each along with some cooked and crumbled bacon.

Top each sandwich with a remaining slice of toast. In a large bowl, whisk 8 eggs and 1½ cups milk along with 1 tablespoon Dijon mustard, and a little additional salt and pepper. Pour the egg mixture evenly over the egg sandwiches in the casserole dish.

Bake in a preheated 350 degree oven for 1 hour. Remove the casserole from the oven and top evenly with 2 cups shredded cheddar cheese. Return the casserole to the oven just long enough for the cheese to melt. Remove, and top with some chopped green onions. Cool for 15 minutes, slice and serve.

When I was going through my file folders trying to find one of my hand painted items to coordinate with this recipe, I ran across this one for these funny little piggy, bacon and egg mugs. I them painted awhile back to match the fabric they’re sitting on. I still get a charge with out of how they turned out. I kind of forgot all about them until now. I hope you’ll get a little chuckle out of them too. Oink. Oink. 🙂
