Ingredients

This recipe calls for simple, wholesome ingredients that come together to create a symphony of flavor and texture. The key is to use bread that has had a chance to dry out a bit – this allows it to soak up the custard beautifully without becoming mushy.

• 20-25 slices of bread (about 1-inch thick, it’s crucial that the bread is stale but not hard)
• Softened butter, for greasing and spreading
• 1 (12 ounce) jar of orange marmalade (room temperature)
• 2 ¾ cups of full-fat milk
• ⅓ – ½ cup of granulated sugar
• 2 teaspoons of vanilla extract
• ⅛ – ¼ teaspoon of ground nutmeg
• 6 large eggs
• ½ teaspoon of ground cinnamon
• 1-2 tablespoons of granulated sugar (for the topping)
• ½ cup of finely chopped walnuts (you can use more), or ½ cup of pecans (you can also use more)

Equipment Needed

To bring this delightful casserole to life, you’ll want to have a few essential kitchen tools ready:

• A 13 x 9-inch baking dish
• A medium-sized bowl for whisking the custard
• A small cup or bowl for mixing the topping
• A whisk
• A knife for slicing bread (if not pre-sliced)
• A spatula or butter knife for spreading butter and marmalade
• An oven for baking

Instructions

The beauty of this French toast casserole lies in its simple assembly and the magic of overnight refrigeration. Here’s how to create this show-stopping brunch dish:

1. Begin by greasing a 13 x 9-inch baking dish with softened butter. Ensure the entire surface is well-coated to prevent sticking.
2. Next, take your bread slices. Using a spatula or butter knife, spread softened butter lightly over each slice of bread. Aim for an even, thin layer.
3. Now, arrange the bread in the prepared baking dish. Arrange 12 bread slices, buttered side down, overlapping slightly in the bottom of the baking dish. This creates the base layer of your casserole.
4. With the first layer of bread in place, it’s time for the star ingredient. Spread the room-temperature orange marmalade evenly over these bread slices. Don’t be shy; a generous layer will ensure a delightful citrusy burst in every bite.
5. Carefully place the remaining bread slices on top, again with the buttered side down, creating the top layer of your casserole.
6. In a medium-sized bowl, whisk together the milk with ⅓ to ½ cup of granulated sugar, 2 teaspoons of vanilla extract, ⅛ to ¼ teaspoon of ground nutmeg, and the 6 large eggs. Continue whisking until the mixture is well combined and smooth.
7. Gently and evenly pour the egg mixture over the bread in the baking dish. Ensure all the bread has a chance to absorb some of the custard.
8. This is the crucial step for developing flavor and texture. Cover the baking dish tightly with plastic wrap or aluminum foil. Then, refrigerate the casserole for 8 to 24 hours. This allows the bread to fully soak up the custard and the flavors to meld beautifully.
9. When you are ready to bake, preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius).
10. While the oven is preheating, prepare the flavorful topping. In a small cup or bowl, mix together the 1-2 tablespoons of granulated sugar with the ½ teaspoon of ground cinnamon and the ½ cup of finely chopped walnuts or pecans.
11. Sprinkle this cinnamon-sugar-nut mixture evenly on top of the bread casserole.
12. Place the baking dish in the preheated oven. Bake for about 45 to 60 minutes, or until the casserole is golden brown and appears set when gently shaken. You can also insert a knife near the center; if it comes out clean, it’s done.
13. Once baked to perfection, remove the casserole from the oven. Let it stand for 10 minutes before serving. This allows the casserole to settle and makes it easier to slice.
14. Just before serving, sprinkle the remaining chopped nuts over the top of the casserole for an extra crunch and visual appeal.

Expert Tips & Tricks

To elevate your Overnight Marmalade French Toast Casserole from delicious to extraordinary, consider these seasoned chef insights:

• Bread is Key: The success of this dish hinges on using stale bread. Freshly baked bread will absorb too much liquid and become soggy. If your bread isn’t stale enough, you can lightly toast slices in a low oven (around 250°F/120°C) for 10-15 minutes until slightly dried out, but not browned.
• Marmalade Magic: Ensure your marmalade is at room temperature. This will make it easier to spread evenly over the bread without tearing it. If your marmalade is very stiff, you can gently warm it for a few seconds in the microwave or in a small saucepan over low heat.
• Custard Coverage: When pouring the custard, make sure to try and get some into the crevices between the bread slices. This ensures a more uniform texture throughout the casserole.
• The Overnight Soak: While 8 hours is the minimum, a full 24-hour soak will yield the most tender and flavorful result. If you’re short on time, ensure the bread is sufficiently stale to handle the liquid.
• Oven Variability: Ovens can vary. Keep an eye on your casserole during the last 15 minutes of baking. If the topping is browning too quickly, you can loosely tent the dish with aluminum foil.

Serving & Storage Suggestions

This Overnight Marmalade French Toast Casserole is a showstopper on its own, but it also pairs wonderfully with a side of fresh berries, a dollop of whipped cream, or a drizzle of maple syrup. For an extra decadent touch, serve it with crispy bacon or breakfast sausage.

• Serving: Serve warm directly from the baking dish. The 10-minute resting period is essential for the casserole to set up, making it easier to portion.
• Storage: Leftovers can be stored, tightly covered, in the refrigerator for up to 3 days.
• Reheating: To reheat individual portions, place them on a microwave-safe plate and heat in the microwave until warmed through. For larger portions, cover the baking dish with foil and reheat in a 350°F (175°C) oven for about 15-20 minutes, or until heated through.

Variations & Substitutions

While this recipe is a classic for a reason, feel free to explore these delightful variations and substitutions to tailor it to your preferences:

• Bread Swap: While challah or brioche are ideal, a good quality day-old white bread or even a slightly dense sourdough can work. Just ensure it’s not too soft.
• Citrus Twist: Experiment with different marmalades! Seville orange marmalade offers a classic bitter-sweet profile, while a grapefruit or even a blood orange marmalade can add a unique twist.
• Nutty Alternatives: If walnuts or pecans aren’t your favorite, consider slivered almonds or even chopped hazelnuts for the topping.
• Spice it Up: For a warmer, more complex flavor profile, add a pinch of ground cardamom or a whisper of ginger to the egg custard.
• Gluten-Free Goodness: For a gluten-free version, seek out a good quality gluten-free bread that is also suitable for French toast – it needs to hold its structure well.

FAQs

Q: Why does the bread need to be stale for this recipe?
A: Stale bread has a firmer texture and less moisture, which allows it to absorb the custard evenly without becoming mushy, ensuring a delightful texture.

Q: Can I make this casserole without refrigerating it overnight?
A: While the overnight refrigeration is highly recommended for optimal flavor and texture, you can bake it after about 1-2 hours of soaking. However, the bread may not absorb the custard as deeply.

Q: What kind of bread is best for this French toast casserole?
A: Rich, eggy breads like challah or brioche are excellent choices because they are dense and soak up the custard beautifully.

Q: My casserole is browning too quickly on top. What can I do?
A: If the topping is browning faster than the inside is cooking, loosely tent the casserole with aluminum foil for the remainder of the baking time.

Q: Can I freeze this French toast casserole?
A: Yes, you can freeze the assembled, unbaked casserole. Cover it tightly with plastic wrap and then aluminum foil. Thaw overnight in the refrigerator before baking as directed. You can also freeze baked portions for later enjoyment.
