Breakfast Casserole made with Sourdough Bread

As a high school student, I participated in a month-long exchange program with a student from Germany.  She stayed with my family for a month one year, and I went and stayed with her family the next year.  It was such a great experience, and one that really opened my eyes to how differently people live from country to country.

One of my favorite parts of living in Germany for that short time was the food.  Every morning Herta, my host mom, would run down the street to the neighborhood bakery and pick up fresh bread for the day’s meals.  It was heavenly.

If you’ve never had fresh baked bread, you are really missing out.  The sandwich bread we are sold is really just an imitation of bread.  Fresh bread is so much more flavorful and filling.

This year, we enrolled my kids in a homeschooling group that’s located about 40 minutes from our home.  It’s once a week, and everyone brings lunches and we all eat together.  There aren’t kitchen facilities available to us, so we usually bring sandwiches.  I really wanted to bake fresh bread to make our sandwiches, but I just didn’t have the time.

So when I was in Fred Meyer last week buying some groceries, I decided to ask at the bakery if they had any good, fresh breads available that would be good for making sandwiches.  I knew I didn’t want a bread from the bread aisle, since most of those were baked weeks ago, so I went directly to the bakery instead.

It turns out that they did indeed have some great bread, called California Goldminer Sourdough Bread.  I was excited to find out that it’s baked fresh in the bakery every day!  California Goldminer Sourdough Bread is perfect for my needs. 

It’s not some funky hard-to-use shape, but a sandwich shape that’s perfect for us to make sandwiches, and it comes in 5 delicious flavors: Sourdough Square, Toasted Onion Square, Seeded Rye Square, Cracked Wheat Square, and Sesame Square. 

And I can’t help but love the rich heritage behind sourdough– thinking of how starters used to be passed down from generation to generation.  Or in the case of California Goldminer Sourdough Bread, it was the bread goldminers in California ate.  It’s kind of cool when you think about it.

I picked up a loaf of Toasted Onion Square and a loaf of Sesame Square.  We used some for sandwiches, but there’s inevitably some left over that I want to use before it goes bad.  Obviously, a good sourdough bread can be frozen for later use or turned into bread crumbs or croutons, but instead I decided to use the leftovers to make breakfast!

Ever since I made a breakfast casserole at Christmas, my kids have been asking me to make another one.  So I used the leftover slices of California Goldminer Sourdough Bread to make a breakfast casserole, and it was amazing!

This sourdough bread breakfast casserole is easy to put together, and you can bake it right away.  Or if you would rather prepare it the night before, you can refrigerate it and bake it in the morning– just add 5-10 minutes to the baking time.

If you only have a slice or two left over (or just the ends of the loaf, if you don’t like a sandwich made with those), just put them in a freezer bag and save them up until you have enough to make this.  There’s no reason to let a single slice of delicious fresh-baked bread go to waste!

Just made this and still very runny not cooking all the way through. Is fluid at the bottom normal?

@Emily, There shouldn't be liquid left over. As it cooks, the liquid is absorbed by the bread. If you whisked the milk with the eggs, anything that's not absorbed ought to turn to more of a baked scrambled egg, at the least. Maybe try baking it a bit longer.
