Step-by-Step French Toast Casserole Recipe Instructions

Let’s walk through the process in detail so you can achieve flawless results.

👩‍🍳 Instructions

1. Prepare the Bread

Cut the bread into 1-inch cubes and spread them evenly in a greased 9×13-inch baking dish. Avoid packing the bread too tightly; this helps the custard distribute evenly.

Tip: Slightly stale or day-old bread works best, as it absorbs more custard without becoming mushy.

---

2. Make the Custard

In a medium bowl, whisk together the eggs, milk, heavy cream, vanilla extract, and sugar until fully combined. The mixture should be smooth and slightly frothy.

Pour the custard evenly over the bread cubes, ensuring all pieces are coated.

---

3. Refrigerate

Cover the baking dish tightly with plastic wrap and refrigerate for at least 4 hours or overnight. This soaking time is critical for a successful French Toast Casserole Recipe.

Why it matters: The longer soak allows the bread to fully absorb the custard, creating a creamy interior after baking.

---

4. Prepare the Crumb Topping

In a bowl, mix flour, brown sugar, cinnamon, and salt. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.

Transfer the topping to a resealable bag and refrigerate until ready to bake.

---

5. Bake

Preheat the oven to 350°F (175°C). Remove the casserole from the refrigerator and sprinkle the crumb topping evenly over the bread.

Bake uncovered for 45–60 minutes, depending on your texture preference:

• 45 minutes: Softer, creamier center

• 60 minutes: Firmer center with a crispier top

---

6. Serve

Allow the casserole to cool slightly before serving. This helps it set and makes slicing easier.

Serve warm, plain or with maple syrup, fresh fruit, whipped cream, or a dusting of powdered sugar.
