Recommended Products for This Recipe
These are a few products I personally reach for when I make this casserole, based on what has actually made a difference in the final result.
None of these are required, but they make the process smoother, and pair nicely with a Strawberry French Toast Casserole if you want to switch things up later.
1. USA Pan 9×13 Nonstick Baking Dish
I like a heavier baking dish for this recipe because it heats evenly, so the edges do not overbake before the center sets.
It also releases the casserole cleanly, which matters once that streusel has caramelized onto the surface.
2. Nielsen-Massey Pure Vanilla Extract
A good vanilla extract genuinely changes the flavor of the custard here, since it is one of the main flavors carrying the dish.
I keep a bottle of this on hand specifically for baked breakfasts like this one.
3. Brioche Bread Loaf
Brioche has enough richness and structure to soak up the custard without turning mushy, which is the single biggest factor in getting this right.
If your grocery store does not carry it fresh, a shelf stable loaf works in a pinch.
4. Diamond of California Chopped Pecans
Pre-chopped pecans save a step and toast beautifully in the streusel topping.
I like keeping a bag in the freezer so they are always ready for a recipe like this.
5. Grade A Pure Maple Syrup
Real maple syrup makes a noticeable difference over the imitation kind, especially poured over something this rich.
A little goes a long way, so a smaller bottle of real syrup is worth it.
Step-by-Step Instructions: How to Make French Toast Casserole
1. Prepare the Bread
- Cut the brioche or challah loaf into roughly 1 inch cubes, keeping the crust on for extra texture.
- Spread the cubes out on a baking sheet and let them sit uncovered for a few hours, or overnight, so they dry out slightly.
- Slightly stale bread soaks up the custard without falling apart, so do not skip this step if your bread is very fresh.
- Grease your 9×13 inch baking dish with butter, then add the bread cubes in an even layer.
2. Make the Custard
- In a large mixing bowl, whisk together the eggs, whole milk, and half and half until fully combined.
- Add the granulated sugar, vanilla extract, ground cinnamon, nutmeg, and salt.
- Whisk until the sugar has mostly dissolved and the mixture looks smooth and pale yellow.
- Whisk in the melted butter last, drizzling it in slowly so it does not clump.
3. Assemble the Casserole
- Pour the custard mixture evenly over the bread cubes in the baking dish.
- Use a spatula or your hands to gently press the bread down so every piece gets coated.
- Make sure there are no dry pockets of bread left uncovered, especially in the corners of the dish.
4. Chill the Casserole
- Cover the dish tightly with plastic wrap or foil.
- Refrigerate for at least 1 hour, though overnight (8 to 12 hours) gives the best texture.
- This resting time lets the bread fully absorb the custard so the finished casserole is soft in the center instead of soggy or dry.
5. Make the Streusel Topping
- In a separate bowl, combine the flour, brown sugar, cinnamon, and salt for the streusel.
- Add the cold cubed butter and use a pastry cutter or fork to work it into the dry ingredients until the mixture looks like coarse crumbs.
- Stir in the chopped pecans.
- Cover and refrigerate the streusel separately until you are ready to bake, so the butter stays cold.
6. Bake the Casserole
- Preheat your oven to 350 degrees Fahrenheit.
- Remove the casserole from the fridge and let it sit at room temperature for about 15 minutes while the oven heats.
- Sprinkle the chilled streusel topping evenly over the top of the soaked bread.
- Bake uncovered for 40 to 45 minutes, until the top is golden brown and the center is set with only a slight jiggle.
- If the top browns too quickly, loosely tent it with foil for the last 10 to 15 minutes.
7. Rest and Serve
- Let the casserole rest for 5 to 10 minutes after baking so it firms up slightly and is easier to slice.
- Cut into squares and serve warm, drizzled with pure maple syrup.
This same method works well for my Stuffed French Toast Recipe if you want a version with a filling baked inside instead.
Tips for The Best French Toast Casserole
A few small details make the difference between a good casserole and a great one.
- Use bread that is a day or two old, or dry it in the oven at a low temperature for 10 minutes if you are short on time
- Do not skip the chilling step, since it is what makes the custard fully absorb
- Keep the streusel butter cold right up until you sprinkle it on, for the best crumbly texture
- Check for doneness by inserting a knife in the center, it should come out mostly clean
- Let the dish come closer to room temperature before baking so it cooks evenly

Serving Suggestions
This casserole is rich enough to be the centerpiece of a brunch spread, but it also pairs well with lighter sides.
A little fresh fruit or crispy bacon on the side balances out the sweetness nicely.
- Fresh berries or sliced bananas on top
- A dusting of powdered sugar
- Crispy bacon or breakfast sausage on the side
- A dollop of whipped cream for special occasions
- Hot coffee or fresh orange juice to round out the meal
For something savory to round out the table, try my Air Fryer French Toast alongside a batch of eggs.
Variations of French Toast Casserole
Once you have the base method down, it is easy to switch things up depending on what you have on hand or what the season calls for.
- Swap pecans for walnuts or leave nuts out entirely for allergies
- Add a layer of fresh berries between the bread and custard
- Use cream cheese cubes tucked between the bread pieces for a stuffed version
- Swap half the cinnamon for pumpkin pie spice in the fall
- Use croissants instead of brioche for an even richer texture
My Croissant Breakfast Casserole is a good example of that last variation done as its own recipe.
Storage and Reheating
Leftovers hold up well, which makes this a great recipe to make ahead for a full week of easy breakfasts.
- Store leftovers covered in the refrigerator for up to 4 days
- Reheat individual portions in the microwave for 30 to 45 seconds
- Reheat larger portions in a 325 degree oven, covered with foil, for about 15 minutes
- Freeze baked and cooled squares in an airtight container for up to 2 months
- Thaw frozen portions in the fridge overnight before reheating

Health Benefits of Key Ingredients
While this is very much a treat-style breakfast, a few of the ingredients do offer some nutritional upside.
Eggs and dairy contribute protein and calcium, while pecans bring healthy fats and a bit of fiber to the plate.
- Eggs provide protein and important B vitamins
- Milk and half and half offer calcium and vitamin D
- Pecans contain heart-healthy unsaturated fats
- Cinnamon has natural antioxidant properties
- Whole eggs and dairy help keep you full through the morning

FAQs About French Toast Casserole
1. Can I make this French Toast Casserole ahead of time?
Yes, this recipe is actually designed to be made the night before.
Assemble it, cover it, and refrigerate it for up to 12 hours before baking.
2. What is the best bread to use?
Brioche or challah work best because they are soft, slightly sweet, and sturdy enough to hold up to the custard.
Day old bread absorbs the liquid better than fresh bread.
3. Can I skip the overnight chilling step?
You can chill it for as little as 1 hour if you are short on time, though the texture will be slightly less custardy.
Overnight chilling gives the most consistent results.
4. Why did my casserole turn out soggy in the middle?
This usually happens if the bread was too fresh or the custard to bread ratio was off.
Using slightly stale bread and pressing it down well during assembly helps prevent this.
5. Can I freeze French Toast Casserole?
Yes, baked and fully cooled squares freeze well for up to 2 months in an airtight container.
Thaw them in the refrigerator overnight before reheating in the oven.
