      Instructions

      Step 1: Prep the Bread

      Cut or tear your sourdough into cubes. Aim for bite-sized pieces for easy portioning.

      Arrange the bread cubes in your greased baking dish. This helps them stay put when you pour over the custard, ensuring an even soak.

      Step 2: Make the Custard

      Whisk together eggs, milk, sweetener, vanilla extract, cinnamon, and salt in a large mixing bowl until everything is well combined.

      Pour this mixture evenly over the bread cubes. Press down gently so each piece is soaked.

      Step 3: Create the Streusel

      In a separate bowl, combine flour, brown sugar, cinnamon, and a pinch of salt.

      Cut in cold butter until you get pea-sized crumbles. This forms a crumbly topping that will crisp up beautifully in the oven.

      Step 4: Chill or Bake

      If you want a quick turnaround, you can bake immediately.

      For best flavor infusion, cover your sourdough french toast casserole and refrigerate overnight, letting the bread fully absorb the custard.

      Step 5: Bake to Perfection

      Preheat oven to 350°F (175°C).

      Scatter your streusel topping over the casserole if using.

      Bake for about 35–45 minutes, or until golden brown and the center is set but still tender.

      Let it cool slightly before serving.
