Ingredients for French Toast with Jam Brioche Casserole

1 loaf brioche bread (about 14–16 oz), sliced into ¾-inch thick slices
6 large eggs
1 ¾ cups whole milk
½ cup heavy cream
⅓ cup granulated sugar
1 tablespoon vanilla extract
½ teaspoon ground cinnamon (optional)
¼ teaspoon salt
¾ cup fruit jam (raspberry, strawberry, apricot, or mixed berry)
2 tablespoons unsalted butter, melted (for brushing)
Powdered sugar, for dusting (optional)
Fresh berries or mint, for garnish (optional)
Maple syrup or whipped cream, for serving (optional)

Step-by-Step Instructions for French Toast with Jam Brioche Casserole

Step 1:
Grease a 9×13-inch baking dish with a little butter or cooking spray. Set it aside while you prep the bread. This will ensure your casserole releases easily and develops a nice golden crust on the bottom.

Step 2:
Cut the brioche into slices about ¾-inch thick. If the loaf is pre-sliced, that’s fine too. Day-old bread works best here—it soaks up the custard beautifully without falling apart. If using fresh bread, you can lightly toast it in the oven for 5 minutes to dry it out.

Step 3:
Spread a thin layer of your chosen jam on one side of half the brioche slices. Think of it like making little open-faced jam sandwiches. Then top each with a plain slice to create a sandwich effect. This layering gives you a jammy surprise in the middle of the casserole.

Step 4:
Arrange the jam sandwiches in the greased baking dish. You can lay them flat, overlap them slightly in a row, or stand them upright like a bread pudding. There’s no wrong way—it’s all about the final look you want.

Step 5:
In a large mixing bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, cinnamon (if using), and salt. Whisk until fully combined and slightly frothy—this will be your custard base.

Step 6:
Slowly pour the custard mixture over the arranged brioche sandwiches in the dish. Make sure to cover all the bread, especially the tops. Press down lightly with a spatula to help the bread absorb the custard.

Step 7:
Cover the dish tightly with foil or plastic wrap and refrigerate for at least 4 hours, or overnight if possible. This allows the custard to fully soak into the bread for the softest, most flavorful texture.

Step 8:
When ready to bake, preheat your oven to 350°F (175°C). Uncover the casserole, brush the tops of the bread with melted butter for extra color, and place it in the oven.

Step 9:
Bake for 40 to 45 minutes, or until the custard is set and the tops are golden brown. If the top starts browning too quickly, you can tent it loosely with foil during the last 10 minutes.

Step 10:
Remove from the oven and let it cool for 10 minutes before serving. Dust with powdered sugar, garnish with fresh berries or mint if desired, and serve with maple syrup or whipped cream on the side.

Ingredient Background

Let’s take a moment to shine the spotlight on a few key ingredients that make this casserole so swoon-worthy. Starting with brioche, this bread is like the golden child of the baking world. Originating from France, brioche is enriched with butter, eggs, and milk, which gives it that tender crumb, slightly sweet flavor, and pillowy texture. It’s basically what would happen if bread and cake had a baby. Because of its richness, it soaks up the custard without disintegrating, making it a natural fit for French toast bakes.

Next up: fruit jam. A classic pantry staple that brings nostalgic sweetness to the table. Whether you go for raspberry, apricot, or strawberry, jam adds a burst of fruity contrast to the creamy custard. Most jams are made from simmered fruit and sugar, often cooked down to concentrate the flavor. While traditionally used on toast, in this casserole, jam acts like a flavorful glue between brioche slices—transforming basic French toast into a layered dessert-like dish.

Then there’s the custard, the silky, luxurious mixture made from eggs, milk, cream, sugar, and flavorings like vanilla and cinnamon. Custard is the backbone of French toast and bread pudding alike. Its job is to bind everything together and add creaminess. Eggs provide structure, while milk and cream bring richness and moisture. Vanilla enhances sweetness and gives that familiar cozy flavor we all associate with dessert-style breakfasts.

Each of these ingredients brings something special to the table, and when combined, they create an alchemy of taste and texture that turns a simple breakfast into something unforgettable.

Technique Tips for French Toast with Jam Brioche Casserole

This recipe is pretty foolproof, but a few subtle techniques can take your casserole from good to unforgettable. Let’s talk custard first. The secret to that rich, velvety texture is a proper egg-to-liquid ratio. Too many eggs and you’ll end up with a scrambled texture. Too much milk, and it won’t set. For this casserole, we’re going with a Goldilocks blend of whole milk and cream, which gives structure and richness without being too dense.

Now, about soaking time. A quick dip won’t do the trick here. The bread needs time to soak up all that custard—overnight is ideal. During this time, the bread absorbs every bit of flavor, softening and melding with the jam. If you’re short on time, give it at least four hours in the fridge. You can press the bread down gently after pouring the custard to help it absorb more quickly.

Lastly, let’s talk about baking and browning. You want the custard to set but not dry out, and the tops of the bread to get golden and just a little crisp. Covering the dish for part of the baking time helps with even cooking, then uncovering it at the end allows for that picture-perfect finish. A quick brush of butter before baking adds shine and deepens the browning. And if you notice the top browning too quickly, a little foil tent saves the day.

Alternative Presentation Ideas

While the traditional way of laying down jam sandwiches in a casserole dish works like a charm, you can definitely get creative with how you present this dish. One option is to go for a spiral pattern, standing the brioche sandwiches on edge and arranging them in concentric circles inside a round baking dish or cast iron skillet. Not only does this look beautiful when baked, but it gives those edges a slightly crispy texture that contrasts beautifully with the soft middle.

Another visually stunning method is to cut the brioche sandwiches diagonally into triangles and stack them slightly overlapping in rows. This presentation adds a little drama to your brunch table and helps jam peek out from the corners of the bread, giving everyone a visual preview of the fruity deliciousness to come. Plus, it makes for easy portioning since each triangle becomes its own serving.

And if you’re going for a more upscale or individual touch, consider making mini casseroles in ramekins or oven-safe mugs. Each guest gets their own personal serving, and they look adorable topped with a dollop of whipped cream or a sprig of mint. It’s a great way to serve this dish at brunch parties or baby showers where presentation counts just as much as flavor.

Freezing and Storing French Toast with Jam Brioche Casserole

Got leftovers? Lucky you. This casserole is just as dreamy the next day. To store in the fridge, let the casserole cool completely after baking. Then cover it tightly with foil or transfer to an airtight container. It’ll stay fresh in the fridge for up to 3 days. When ready to reheat, pop individual portions in the microwave for 30–45 seconds or reheat the whole dish in a 325°F oven until warmed through.

If you’re thinking ahead or making this as a prep-ahead breakfast, this dish freezes beautifully. To freeze before baking, assemble the entire casserole in a freezer-safe dish, wrap tightly in a couple layers of plastic wrap and then foil, and store for up to 2 months. When you’re ready to bake it, let it thaw overnight in the fridge and then bake as directed. Just note that the bread might be extra soft from the long soak, so don’t skip brushing it with butter to get that nice browned top.

You can also freeze leftovers after baking. Slice into individual portions, wrap tightly in plastic wrap, and freeze. These can be microwaved straight from the freezer or reheated in the oven at 350°F until hot and slightly crisp on the edges again. It’s like having gourmet brunch at your fingertips—any day of the week.

Healthier Twist Ideas

If you’re looking to lighten things up a bit, you absolutely can without losing the spirit of this cozy dish. Start by switching the whole milk and heavy cream for unsweetened almond milk, oat milk, or a lower-fat dairy milk like 2%. While the final texture might be slightly less rich, it’ll still be creamy and satisfying. You can also reduce the sugar in the custard if your jam is on the sweeter side—just 2 tablespoons of sugar may be enough if you’re using something like strawberry or raspberry jam.

To bump up the fiber and whole grains, swap the brioche for whole grain challah or a high-quality whole wheat bread. The key is still to choose something enriched and slightly dense so it can soak up custard properly without falling apart. Whole grain breads bring a nutty flavor and slightly chewier texture, which can balance the sweetness of the jam nicely.

Lastly, if you want to increase the protein content or make it more filling without sacrificing flavor, consider adding a dollop of Greek yogurt into the custard mix. It not only adds creaminess but also gives a subtle tang that complements the sweetness of the jam. Pair the casserole with fresh berries or a simple fruit compote on the side for extra fiber, vitamins, and color.

Serving Suggestions for Events

This casserole isn’t just a breakfast dish—it’s a crowd-pleasing centerpiece for so many types of gatherings. Hosting a holiday brunch? Serve it alongside a light arugula salad with citrus vinaigrette and a platter of turkey sausage links or spiced roasted potatoes. The rich sweetness of the casserole balances beautifully with savory sides, creating a full and festive spread that guests will remember.

For a baby or bridal shower, this dish is a dream. Present it in individual ramekins, top each with a swirl of whipped cream and a single raspberry, and pair with mimosas (or sparkling juice for a halal twist). The soft pink tones of strawberry or raspberry jam make it visually perfect for such events, and it pairs well with delicate tea sandwiches or fruit kabobs.

Even a cozy weekend breakfast at home can become special with this casserole. Set the table with a pitcher of warm maple syrup, a pot of tea or coffee, and maybe a bowl of yogurt with granola. It’s casual enough for pajamas but special enough to feel like you’re at a little café. And if you’re cooking for kids? Just add some colorful sprinkles or a drizzle of chocolate syrup to make their morning magical.
