Preparation Steps

To start, preheat your oven and prepare a baking dish by greasing it.

Cubed French bread is layered with sliced peaches, forming the base of the casserole.

Next, whisk together the eggs, milk, heavy cream, and other ingredients to create the custard mixture, which is then poured over the bread and peaches.

For the best results, allow the casserole to refrigerate for at least 30 minutes or overnight. This step ensures that the bread absorbs the custard fully, resulting in a rich and flavorful dish.

Baking to Perfection

After letting the casserole sit, sprinkle brown sugar and melted unsalted butter over the top before placing it in the oven.

Bake until the top is golden brown and the custard is set, which typically takes about 45 to 50 minutes.

The aroma that fills your kitchen during baking is simply irresistible!

Serving Suggestions

Once baked, allow the casserole to cool slightly before slicing.

Serve warm, garnished with a dusting of powdered sugar and a drizzle of maple syrup for added sweetness.

Fresh peach slices and a sprig of mint not only enhance the presentation but also add a refreshing touch to this delightful breakfast dish.

• Serve warm with maple syrup and whipped cream.
  .
• Pair with a side of crispy bacon or breakfast sausage.

• Add a fruit salad or peach smoothie for a full brunch spread.
  .

Tips for the Best Peach French Toast Casserole

Use slightly stale bread so it absorbs the custard better without becoming soggy. Always chill the casserole to allow the custard to soak thoroughly into the bread—overnight is ideal.

For extra flavor, toss the peaches with a little cinnamon sugar before layering. If using canned peaches, drain them well to avoid excess moisture.

And don’t skip the streusel topping—it’s the golden, crunchy crown of this dish.
