Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Unsalted butter creates the base for the caramel sauce, providing richness and helping to create that signature crunchy topping. Using unsalted butter allows you to control the salt content in the recipe.

Packed brown sugar brings deep molasses flavor to the caramel layer and caramelizes beautifully during baking. Light or dark brown sugar works here, with dark providing a more robust flavor.

Corn syrup helps prevent the caramel from crystallizing and adds a smooth texture to the sauce. Light corn syrup is traditional, but honey can work as a substitute in a pinch.

French bread serves as the sturdy foundation that soaks up the custard mixture while maintaining some texture. Day-old bread works particularly well since it absorbs more liquid without falling apart.

Eggs provide structure to the custard and help it set during baking, creating that perfect creamy texture between bread pieces.

Whole milk creates the rich custard base. The fat content is important for a creamy result, though half-and-half or a mixture of milk and cream can be substituted for even more decadence.

Vanilla extract adds warmth and aromatic sweetness that complements the caramel notes. Pure vanilla extract offers the best flavor.

Salt enhances all the other flavors and balances the sweetness. Even this small amount makes a significant difference in the overall taste.

Ground cinnamon brings a warm, spiced note that pairs beautifully with the custard and caramel elements. While optional, it adds a lovely dimension to the dish.

Directions

In a small saucepan over medium heat, melt butter, brown sugar, and corn syrup. Stir until smooth and bubbling, about 3-4 minutes. Pour caramel mixture evenly into the bottom of a 9×13-inch baking dish.
Arrange French bread slices in a single layer over the caramel sauce, overlapping if necessary.
In a medium bowl, whisk together eggs, milk, vanilla extract, salt, and cinnamon (if using). Pour custard evenly over bread, making sure each slice is soaked.
Cover dish with plastic wrap and refrigerate overnight or at least 4 hours.
Preheat oven to 350°F (175°C). Remove plastic wrap and let dish sit at room temperature for 15 minutes.
Bake uncovered for 35-40 minutes until the top is golden and custard is set.
Let cool a few minutes before serving. Invert slices so caramel side is up. Serve warm, optionally with fresh berries or powdered sugar.

Servings and Timing

This recipe serves 6-8 people, depending on portion size and what else you’re serving. The preparation takes about 15 minutes of active time, followed by 4-12 hours of chilling time (overnight is ideal). The baking time is approximately 40 minutes, and the total time from start to finish is about 5 hours, most of which is hands-off. Each serving contains approximately 350 calories.

Variations

Berry-Infused: Add a layer of fresh berries like blueberries or sliced strawberries between the bread slices for a fruity twist.

Nutty Delight: Sprinkle toasted pecans or walnuts over the caramel before adding the bread for added crunch and flavor.

Orange Zest: Add orange zest to the custard mixture for a bright, citrusy note that cuts through the richness.

Chocolate Chip: Scatter chocolate chips between the bread layers for a chocolate lover’s dream breakfast.

Coconut Edition: Use coconut milk instead of regular milk and sprinkle toasted coconut flakes on top during the last 10 minutes of baking.

Maple Caramel: Replace the corn syrup with pure maple syrup for a distinct maple flavor in the caramel.

Storage/Reheating

Refrigeration: Store leftover casserole covered in the refrigerator for up to 3 days. The caramel will harden somewhat when cold but will soften again when reheated.

Freezing: This casserole can be frozen after baking. Allow it to cool completely, then wrap tightly in plastic wrap and aluminum foil. Freeze for up to 1 month. Thaw overnight in the refrigerator before reheating.

Reheating Individual Portions: For the best texture, reheat individual portions in the microwave for 60-90 seconds or until warmed through. The caramel will soften and become gooey again.

Reheating Full Casserole: To reheat a larger portion, cover with foil and warm in a 325°F oven for 15-20 minutes until heated through. Remove the foil for the last 5 minutes if you want to re-crisp the top slightly.

FAQs

Can I make this with regular sandwich bread instead of French bread?

While you can use sandwich bread in a pinch, it won’t deliver the same texture as French bread. Sandwich bread is softer and may become too mushy. If you must substitute, consider using brioche, challah, or another sturdy bread that can stand up to soaking.

Why does my casserole need to soak overnight?

The overnight soak allows the bread to fully absorb the custard mixture, resulting in a consistent texture throughout. This creates that perfect balance between creamy and structured, rather than having dry bread floating in liquid custard.

Can I make this dairy-free?

Yes, you can substitute plant-based butter and non-dairy milk like almond, oat, or coconut milk. Choose a fuller-fat version of non-dairy milk for the best results, and note that it may change the flavor profile slightly.

What if I don’t have time for an overnight soak?

While overnight is ideal, a minimum of 4 hours of soaking will work. To speed up absorption, you can press the bread gently into the custard occasionally during the soaking period, and use slightly stale bread which absorbs liquid more quickly.

My caramel hardened after baking. What happened?

This usually happens if the caramel was overcooked initially or if the casserole was baked too long. Next time, cook the caramel just until it’s smooth and bubbling, and check the casserole early during baking time.

Can I make this without corn syrup?

Yes, you can substitute honey, maple syrup, or golden syrup for corn syrup. The texture may be slightly different, but the recipe will still work well.

Is this casserole too sweet for breakfast?

While it is sweet, it’s comparable to other breakfast treats like pancakes with syrup. For a less sweet version, reduce the brown sugar to 3/4 cup and serve with fresh fruit to balance the sweetness.

Can I add spices other than cinnamon?

Absolutely! Nutmeg, cardamom, ginger, or pumpkin pie spice would all work beautifully in this recipe. Add them to the custard mixture along with or instead of the cinnamon.

Why is my French toast casserole soggy in the middle?

This could happen if your oven temperature is too low or if the casserole wasn’t baked long enough. The custard should be set but still moist. You can test by inserting a knife in the center – it should come out mostly clean with perhaps a bit of moisture.

Can I prepare this further in advance than overnight?

Yes, you can assemble this casserole up to 24 hours in advance. Beyond that, the bread may become too soggy. For longer advance preparation, consider freezing the unbaked casserole and thawing it overnight before baking.
