Sourdough French Toast Bake

This Sourdough French Toast Bake is a delicious bread, egg, and milk mixture baked up into a casserole-style French toast. It is the perfect way to use up leftover loaves of sourdough bread.

Aside from the sourdough world, I find that when I use the term “sourdough” to make something sweet, I get a look. Most people just don’t understand that sourdough can be used for a wide variety of baked goods, sweet treats, and yes a sourdough French toast bake like this.

This is an easy sourdough recipe and the best part is, is that it helps to use up those last bits of the sourdough loaf that sit on the countertop drying out. If you make bread often you know there’s always some to use up and there is a need to get creative with it. After all. we can’t let all that hard work of making it go to waste (literally).

For this, we make croutons, bread crumbs, and strata quite regularly in our house. If there is any leftover, which there rarely is, I love using my sourdough cinnamon swirl bread. This breakfast bake was born out of that same idea. A great way to use up old bread however, for Sunday morning or special occasions I have used fresh bread and even sandwich bread from the market to make it.

No matter what you use, I am sure you will enjoy it just the same.

What You Will Need To Make It

8 cups cubed sourdough bread (this is a great way to use leftover sourdough bread)

1 tsp cinnamon

6 eggs

1 cup of milk

1 tsp vanilla

6 tbsp butter

Cinnamon and Sugar Topping

2 tbsp organic sugar

1 tsp cinnamon

Tools

Casserole Dish or Cast Iron Skillet

Directions

Cube the sourdough bread into bite sized pieces (about 1-inch cubes) and place them into a large bowl.

In a medium bowl, mix together the 6 eggs, milk, vanilla, 1 tsp of cinnamon, and 4 tbsp of melted butter.

Mix well and pour over the cubed bread in a bowl. Allow the bread to absorb the mixture for about 5 minutes. While the bread sits, pre-heat your oven to 350℉.

During this time, place your skillet on the stovetop and melt the other 2 tbsp of butter. Make sure to spread it evenly across the pan as it melts.

Remove from the heat, and pour in the soaked bread mixture.

Combine the sugar and cinnamon for the topping mixture and sprinkle it evenly across the top of your French toast mixture.

Bake for approximately 25 minutes until golden brown. Serve with a drizzle of maple syrup or a berry compote.

Baking Notes

• Can be made into an overnight breakfast bake by putting it together in a prepared baking dish, and covering it with plastic wrap. Place in the fridge. The following morning, add a few squares of butter to the top and bake as instructed.
• Make sure to allow the bread to do at least a 5-minute soak before adding to your baking dish or skillet to allow the bread to absorb the batter.
• You can use any left over bread you have on hand, not just sourdough. I have mixed two different loaves to use them up for this recipe and it worked great.
• If you are using a baking dish in place of a skillet, make sure to still add the 2 tbsp of melted butter to the bottom of the dish before adding the cubed bread mixture.

Benefits Of Sourdough

We all love the taste of sourdough bread, but it’s a healthier option than regular store-bought bread like white bread or wheat loaves. It’s made with lower levels of phytate, which makes it easier to digest and more nutritious. Plus, it’s a great option for gluten-sensitive people, since it’s a fermented food with a bacteria-yeast mix that breaks down starches before they’re even digested. It’s also a type of prebiotic, which means it’ll help keep your digestive system healthy.

​How To Store

Store any leftover French toast in an airtight container or use a piece of aluminum foil to cover the casserole dish to store in the fridge. You can reheat the next morning right in the same dish.
