This rich Crème Brûlée French Toast Casserole turns your regular breakfast into a luxurious treat that's basically dessert first thing in the morning. The sugar on top gets all crispy while underneath, the bread stays soft and velvety after soaking in custard.
I started making this for our Christmas breakfast three years back and now we can't imagine the holiday without it. Getting it ready the night before means I don't miss out on family time and can actually sit down with my coffee while presents are being opened.
Ingredients
- Unsalted butter: builds a tasty caramel foundation without making things too salty
- Brown sugar: gives you that rich, dark sweetness that makes the caramel extra tasty
- Corn syrup: keeps your caramel nice and smooth with no sugar crystals forming
- Large eggs: add thickness and richness to the custard mixture
- Whole milk: creates that dreamy creamy texture don't try to use low-fat kinds
- Vanilla extract: brings wonderful aroma go for real vanilla not the fake stuff
- French bread: soaks up all the custard perfectly without turning to mush
- Ground cinnamon: you can skip it but it really adds nice cozy flavor
Step-by-Step Instructions
- Make the Caramel Base:
- Mix butter brown sugar and corn syrup in a pan over medium heat. Keep an eye on it while it bubbles for about 3-4 minutes until it's smooth all the way through. Right away pour it into your baking dish making sure it covers the bottom evenly. It'll get a bit firmer as it cools which is exactly what you want for that true crème brûlée feeling.
- Arrange the Bread:
- Cut your French bread into thick slices about an inch wide and put them in one layer on top of the caramel. You might need to push them together or overlap them a little bit depending on your bread. Try to make a solid layer so the custard soaks in evenly everywhere. Bread that's a day old actually works better because it soaks up more liquid.
- Prepare the Custard:
- Mix eggs milk vanilla salt and cinnamon together until they're well combined and a bit foamy. Pour this mix slowly over your bread, giving each piece a chance to soak before adding more. Press the bread down gently to help it absorb the liquid. Cover everything with plastic wrap and let it sit in the fridge overnight or at least 4 hours. This waiting time really matters for getting that perfect custardy texture.
- Bake to Perfection:
- Heat your oven to 350°F and take the casserole out to warm up for about 15 minutes while the oven gets hot. Bake it uncovered for 35-40 minutes until the top turns golden and the custard firms up. You'll know it's done when the middle doesn't wobble anymore but still looks moist. The edges should be slightly crispy and pulling away from the dish sides.
- Serve with Style:
- Let it cool for 5 minutes then flip portions onto plates so the caramel side shows up on top. When you reveal that shiny caramel layer, it really wows everyone. Throw some fresh berries on top for color and a bit of tartness to balance out the sweetness.

You Must Know
I never skip the corn syrup in this dish. I tried making it once without and my caramel got all grainy instead of having that smooth glossy look. That tiny amount really changes everything between a good breakfast and an amazing one.
Choosing the Right Bread
The type of bread really matters for how this turns out. Bread that's a day old works great since it's lost some moisture and won't get soggy when soaking in the custard. French bread has just the right structure, but using brioche or challah will make it even richer because they contain more eggs and butter. Don't use regular sliced sandwich bread as it'll fall apart during the overnight soak.
Make It Your Own
You can easily change this casserole to suit your taste. Try putting thin apple slices between the bread pieces or add some orange zest to the custard for brightness. For a more adult version, throw in a spoonful of Grand Marnier or bourbon to the custard mix. During autumn, swap the cinnamon for pumpkin pie spice to get that fall feeling. The recipe still works perfectly even with these creative changes.

Serving Suggestions
This casserole tastes great by itself but goes really well with sides that cut through the sweetness. Serve some crispy bacon or breakfast sausage for a savory balance. A side of fresh fruit salad adds nice freshness. If you want to go all out, warm maple syrup can go over individual servings though many people find it's sweet enough already. When serving for brunch, add a simple green salad with dressing to make it a complete meal.

Challah, brioche or French bread work wonderfully. They soak up all that custard goodness without falling apart.
