History
While the precise origins of combining hot cross buns with French toast techniques aren't well documented, this fusion dish represents the natural evolution of two beloved breakfast traditions.
You'll find that hot cross buns, originally eaten on Good Friday, date back to the 12th century in England, while French toast's history stretches even further to ancient Roman times.
In modern kitchens, you've likely noticed how cooks are increasingly transforming traditional recipes into convenient make-ahead dishes.
This casserole adaptation emerged as busy families sought ways to maintain holiday traditions while simplifying preparation.
The marriage of these two classics gives you the best of both worlds – the aromatic spices and fruit of hot cross buns combined with the custardy richness of French toast, creating a dish that's perfectly suited for contemporary entertaining.
Recipe
The beauty of this make-ahead casserole lies in its simplicity and convenience. Prepare it the night before, and wake up to a hassle-free breakfast that only needs to be popped in the oven. As it bakes, the hot cross buns soak up the custard mixture, creating a crispy top layer while maintaining a soft, pudding-like interior.
- 8 hot cross buns
- 4 large eggs
- 2 cups (475ml) whole milk
- 1/4 cup (60ml) maple syrup
- 1 teaspoon vanilla extract
- Butter for greasing
Cut hot cross buns into 1-inch cubes and arrange in a buttered 9×13-inch baking dish. Whisk together eggs, milk, maple syrup, and vanilla extract in a large bowl until well combined. Pour the mixture evenly over the bun cubes, gently pressing down to ensure all pieces are soaked.
Cover with plastic wrap and refrigerate for at least 4 hours or overnight. Before baking, let stand at room temperature for 30 minutes, then bake uncovered at 350°F (175°C) for 45-50 minutes until golden brown and set in the middle.
For optimal results, check the casserole at the 40-minute mark by gently shaking the dish – the center should be slightly jiggly but not liquid. The casserole will continue to set as it cools. To prevent the top from becoming too dark, cover with foil if it browns too quickly during baking.
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days and reheated in individual portions in the microwave.
Cooking Steps
Start by cutting your hot cross buns into uniform one-inch cubes and arranging them in a greased baking dish.
While separately whisking together the eggs, milk, maple syrup, and vanilla extract until well combined, you'll then pour this custard mixture evenly over the cubed buns.
Make sure to press down gently so all pieces are thoroughly soaked. After refrigerating the casserole overnight, you'll bake it at 350°F for 45-50 minutes until it's golden brown on top and slightly jiggly in the center.
Step 1. Slice Buns Into Cubes
Grab your hot cross buns and a sharp serrated knife to begin the essential first step of creating your breakfast casserole.
Place each bun on a cutting board and slice it horizontally, then vertically into even, one-inch squares. You'll want consistent sizing to ensure uniform soaking and baking throughout the dish.
Work with a gentle sawing motion to prevent crushing the buns, which will help maintain their texture. If you're using fresh buns, they'll cut more easily, but day-old buns will actually work better for the final dish as they'll absorb more custard.
Once you've cubed all eight buns, you should have enough pieces to create a single layer that completely covers the bottom of your 9×13-inch baking dish.
Step 2. Mix Liquid Ingredients Together
Whisking together your liquid ingredients creates the rich custard base that transforms ordinary hot cross buns into a luxurious French toast casserole.
In a large mixing bowl, combine four large eggs, two cups of whole milk, a quarter cup of maple syrup, and one teaspoon of vanilla extract.
You'll want to whisk these ingredients vigorously until they're completely blended, ensuring there are no streaks of egg visible in the mixture.
The consistency of your custard base is crucial for achieving the perfect French toast texture.
While whisking, you'll notice the mixture becoming smooth and uniform in color.
Make sure you've broken up all the egg whites and yolks completely, as this will help the custard distribute evenly when you pour it over your cubed hot cross buns.
Step 3. Pour Mixture Over Buns
With your custard mixture perfectly blended, the moment has arrived to transform those cubed hot cross buns into something extraordinary.
Pour the egg mixture slowly and evenly over the bun cubes in your prepared baking dish, making sure to cover all pieces thoroughly. You'll want to gently press down on the bread with a spatula to ensure each cube absorbs the liquid properly.
Take care to distribute the custard mixture uniformly, paying special attention to any dry spots that might appear around the edges of the dish.
If you notice any bun pieces floating up, simply press them back down into the liquid. Once you've poured all the custard, give the dish a gentle shake to help the mixture settle between all the layers of bread.
Step 4. Refrigerate Overnight
After you've thoroughly soaked the hot cross bun cubes in the custard mixture, cover the baking dish tightly with plastic wrap and transfer it to your refrigerator for at least 4 hours, though overnight is ideal for the best results.
This resting period allows the hot cross buns to fully absorb the custard mixture, creating a perfectly moist and tender texture throughout the casserole.
You'll notice the bread cubes becoming softer and more saturated as time passes, which is exactly what you want. During this crucial step, the spices and flavors will also meld together, developing a richer, more complex taste profile.
If you're planning to serve the casserole for breakfast, preparing it the night before makes your morning routine significantly easier.
Step 5. Bake Until Golden Brown
The golden-brown perfection of your hot cross bun casserole begins with preheating your oven to 350°F (175°C).
Before baking, remove your chilled casserole from the refrigerator and let it stand at room temperature for 30 minutes, which ensures even cooking throughout.
Place the casserole, uncovered, in the preheated oven and bake for 45-50 minutes, until the top develops a rich golden-brown color.
You'll know it's done when the edges are set but the center still has a slight jiggle – don't worry, it'll continue to set as it cools.
Insert a knife into the middle; it should come out clean with no liquid custard clinging to it.
If the top browns too quickly, you can tent it with foil to prevent over-browning while the center finishes cooking.
Final Thoughts
Creating this delightful hot cross bun French toast casserole brings a fresh twist to your Easter breakfast traditions while saving precious time during busy holiday mornings.
You'll appreciate how this make-ahead dish transforms simple hot cross buns into an impressive breakfast centerpiece that your family will request year after year.
Don't hesitate to experiment with your own variations. You can add dried fruit, nuts, or a sprinkle of cinnamon sugar before baking.
If you're serving a crowd, you'll find this recipe easily doubles, though you'll need to adjust the baking time accordingly.
Remember that the key to success lies in allowing adequate soaking time, ensuring the hot cross buns absorb the custard mixture completely.
You'll know you've mastered it when each bite offers that perfect balance of crispy top and tender center.
