Unlike traditional French toast that requires standing at the stove flipping individual slices, this baked version allows you to prepare everything in advance and let the oven do the work. The sourdough cubes soak up the lemon-infused custard overnight, ensuring every piece is perfectly saturated and ready to transform into a custardy, golden masterpiece. Whether you're hosting a holiday brunch, celebrating a special occasion, or simply treating your family to something memorable, this Lemon Blueberry Sourdough French Toast Bake delivers impressive results with minimal effort.

Ingredients

• 1 loaf (about 400 g / 14 oz) sourdough bread, cut into 1-inch cubes
• 1 ½ cups (225 g) fresh or frozen blueberries
• Zest of 1 lemon
• 6 large eggs
• 2 cups (480 ml) whole milk
• ½ cup (120 ml) heavy cream
• ⅓ cup (65 g) granulated sugar
• 2 tsp pure vanilla extract
• ¼ tsp salt
• Juice of 1 lemon
• 2 tbsp (28 g) unsalted butter, melted
• 2 tbsp (25 g) granulated sugar
• ½ tsp ground cinnamon

Instructions

Step 1: Prepare the baking dish and bread

Grease a 9x13-inch (23x33 cm) baking dish. Arrange the sourdough cubes evenly in the dish. Scatter blueberries and lemon zest over the bread.

Step 2: Make the custard

In a large bowl, whisk together eggs, milk, cream, sugar, vanilla, salt, and lemon juice until fully combined.

Step 3: Assemble the casserole

Pour the custard evenly over the bread and berries, pressing down lightly to ensure all bread absorbs the mixture.

Step 4: Refrigerate

Cover and refrigerate for at least 30 minutes (or overnight for best results).

Step 5: Preheat oven

Preheat oven to 350°F (175°C).

Step 6: Add topping

Drizzle melted butter over the surface. Mix sugar and cinnamon together and sprinkle on top.

Step 7: Bake

Bake uncovered for 45 minutes, or until the center is set and the top is golden brown.

Step 8: Serve

Cool for 10 minutes before serving. Serve warm, optionally with maple syrup or a dusting of powdered sugar.

Zusatztipps für die Zubereitung

For the best texture, use day-old or slightly stale sourdough bread, as it absorbs the custard more effectively without becoming too mushy. If your bread is fresh, you can lightly toast the cubes in a 300°F oven for about 10 minutes before assembling. When pressing the bread into the custard, be gentle but thorough to ensure even saturation. If you notice any dry spots after refrigerating, simply spoon a bit more custard over those areas before baking. The overnight rest is highly recommended as it allows the flavors to meld and ensures the bread fully absorbs the custard, resulting in a perfectly creamy interior with a crispy, golden top.

Varianten und Anpassungen

This recipe is wonderfully adaptable to various dietary needs and flavor preferences. For a dairy-free version, substitute plant-based milk and cream, such as oat or almond milk, and use vegan butter for the topping. Try swapping blueberries for raspberries, blackberries, or even diced strawberries for a different berry profile. For added richness, consider incorporating a cream cheese layer by dotting small cubes of cream cheese among the bread before adding the custard. You can also add a streusel topping instead of the cinnamon-sugar by combining flour, brown sugar, and cold butter. For a more indulgent version, drizzle with a simple lemon glaze made from powdered sugar and lemon juice after baking.

Serviervorschläge

This Lemon Blueberry Sourdough French Toast Bake shines as the centerpiece of a leisurely brunch spread.

For a more elegant presentation, top individual portions with fresh blueberries and a sprinkle of lemon zest. The dish pairs beautifully with crispy bacon or breakfast sausage for those who enjoy a sweet-savory combination. Beverage-wise, it complements a cup of Earl Grey tea perfectly, as the bergamot echoes the citrus notes, or serve alongside mimosas or freshly squeezed orange juice for a festive brunch atmosphere.
