Ingredients for Sourdough French Toast Bake

1 loaf (about 450g, 1 lb) stale sourdough bread, cut into 1-inch cubes
6 large eggs
2 cups whole milk
½ cup heavy cream
½ cup granulated sugar
1 tablespoon pure vanilla extract
1 ½ teaspoons ground cinnamon
¼ teaspoon ground nutmeg
¼ teaspoon salt
4 tablespoons unsalted butter, melted (plus extra for greasing)
Optional: ½ cup chopped pecans or walnuts
Optional: ½ cup fresh berries or sliced bananas for serving
Powdered sugar & maple syrup for topping

Directions: How to Make Sourdough French Toast Bake

Step 1: Prep the Bread and Pan

Grease a 9x13-inch baking dish with butter. Spread the cubed sourdough bread evenly in the dish. If your bread is fresh, consider toasting the cubes in the oven at 300°F (150°C) for 10 minutes to dry them out for better absorption.

Step 2: Make the French Toast Custard

In a large bowl, whisk together eggs, milk, heavy cream, sugar, vanilla, cinnamon, nutmeg, and salt until completely blended and slightly frothy.

Step 3: Assemble the Sourdough French Toast Bake

Pour the custard mixture evenly over the bread cubes. Lightly press bread cubes with the back of a spoon so they absorb the custard. Drizzle melted butter over the top, and sprinkle with nuts if using.

Step 4: Soak & Chill

Cover with plastic wrap. Refrigerate for at least 2 hours, preferably overnight. (If you're short on time, 45 minutes of soaking will do, but overnight yields the best flavor and texture!)

Step 5: Bake to Golden Perfection

Preheat your oven to 350°F (175°C). Remove the dish from the fridge and let sit at room temperature while the oven preheats. Bake uncovered for 40-50 minutes, or until the top is golden brown and the center is set. If the top is browning too quickly, loosely cover with foil for the last 10 minutes of baking.

Step 6: Serve and Enjoy!

Let the Sourdough French Toast Bake cool for 10 minutes, then dust with powdered sugar. Slice and serve with maple syrup, fresh berries, or your favorite toppings.

Notes for Making the Perfect Sourdough French Toast Bake

Day-old or slightly stale bread works best—fresh bread may get mushy.
If the custard looks thin, a few extra cubes of bread will help soak it up.
Let the bake rest before slicing so it holds its shape.
