Ingredients You Need
- Whole-wheat sourdough bread. You can use any bread you like, but we prefer to use sourdough bread because it has more protein and fiber.
- Eggs. Use free-range eggs if possible.
- Milk of choice. We like to use soy milk, but you can also use almond milk, coconut milk, or oat milk.
- Blueberries. Both fresh and frozen blueberries work well here.
- Spices like cinnamon, nutmeg, and salt.
- Sweetener of choice. We like honey, but you can also use maple syrup.
- Lemon zest. For brightness and tang.
- Vanilla extract. Optional, we add it for flavor.
How to Make Sourdough French Toast Casserole
First, start by making the egg mixture. In a medium bowl, whisk the eggs, milk, spices, honey, and lemon zest.
Then, grease a large baking dish with some butter or oil to prevent sticking. Cut your bread into cubes and add it to the baking dish.
Pour the egg mixture over the bread and use a spoon to mix everything up. Make sure each piece of bread is well coated so it's not dry. Add the blueberries on top.
Cover the casserole with aluminum foil and let it rest for at least 1 hour or overnight if possible. This will allow the bread to soak, which results in a better texture.
Then, bake your for 40 minutes in a pre-heated oven to 350ºF (180ºC). Remove the foil halfway through so it can bake on the top and get golden.
This sourdough French toast casserole is perfect topped with some powdered sugar. Just make sure to let it cool a bit before dusting.
My Best Tips
- Use stale bread. Fresh bread has a lot of moisture and won't soak the egg mixture as well. You can leave your bread uncovered on your kitchen counter for at least 1 night.
- Don't skip the soaking! This is essential to make sure your casserole doesn't end up being soggy. If you don't have time to wait in the morning, prepare it the night before and let it soak overnight in the fridge.
- Use any other fruit you like. Any fruit can work with this sourdough French toast casserole- strawberries, pears, apples, etc.
FAQ
The first reason may be that you have used fresh bread. Make sure your bread is at least a day old. Fresh bread contains too much moisture, which won't work well in this recipe.
The second reason may be that you didn't let the casserole soak. This is an important step, so make sure not to skip it. Soak for 2 hours or overnight if possible.
Lastly, you had too much of the egg mixture. Make sure to follow the recipe as written and not add extra eggs or milk. Otherwise, the bread won't be able to soak it all.
If you can't get your hands on fresh seasonal blueberries, you can make this recipe with frozen blueberries instead. No need to thaw, just throw them right in!
Yes! The longer you let the bread soak in the mixture, the better the casserole! You can make this recipe 2 days in advance. Just remember to keep it in the fridge, covered with foil, so it says fresh.
