The Festive Ingredient Lineup

Save

Here’s what you need to assemble this masterpiece of morning convenience. Sturdy, day-old bread is the key!

For the Casserole:

• 1 loaf (about 1 lb or 450g) Day-Old Sturdy Bread: Challah or brioche are ideal, but a good French loaf or sourdough will also work. It MUST be dry and a day or two old.
• 8 Large Eggs: This creates our rich custard base.
• 2 cups (480ml) Whole Milk: For a richer custard. See variations for dairy-free options.
• ½ cup (120ml) Heavy Cream: For extra indulgence. You can sub with more milk if you prefer.
• ½ cup (100g) Packed Brown Sugar: Light or dark brown sugar works great.
• ¼ cup (60ml) Unsulphured Molasses: This is essential for that deep gingerbread flavor.
• 2 tsp Ground Ginger: Don’t be shy!
• 1 tsp Ground Cinnamon: A classic warm spice.
• ½ tsp Ground Nutmeg: Freshly grated is even better.
• ¼ tsp Ground Cloves: A little goes a long way.
• 1 tsp Vanilla Extract: A baking essential.

For the Streusel Topping:

• ½ cup (65g) All-Purpose Flour:
• ½ cup (100g) Packed Brown Sugar:
• 1 tsp Ground Cinnamon:
• ½ cup (113g) Cold Salted Butter: Cut into small cubes.

Tools & Kitchen Gadgets Used

No fancy equipment is needed to pull off this impressive breakfast.

• 9×13 inch Casserole or Baking Dish: This is the perfect size for one loaf of bread.
• Large Mixing Bowl: For whisking up the custard.
• Medium Mixing Bowl: For the streusel topping.
• Whisk: Absolutely essential for a smooth, well-mixed custard.
• Serrated Bread Knife: The best tool for easily cubing your bread.
• Pastry Blender or Your Fingers: For cutting the butter into the streusel.

Step-by-Step Guide to a Stress-Free Holiday Morning

This is a two-part process: a quick assembly the night before, and an even quicker bake in the morning.

H3: The Night Before (The 15-Minute Assembly)

1. Prep Your Pan and Bread: Generously grease your 9×13 inch baking dish. Cut your day-old bread into 1-inch cubes and spread them evenly in the dish.
2. Make the Custard: In your large mixing bowl, whisk the 8 eggs until they are well beaten. Whisk in the milk, heavy cream, brown sugar, molasses, all the spices (ginger, cinnamon, nutmeg, cloves), and vanilla extract. Keep whisking until everything is smooth and fully combined.
3. Soak It Up: Pour the custard mixture as evenly as possible over the bread cubes in the baking dish. Gently press down on the bread with a spatula to help it absorb the liquid.
4. Chill Out: Cover the dish tightly with plastic wrap or foil and refrigerate overnight, or for at least 8 hours. This soaking time is not optional!

H3: The Morning Of (The “Look at Me, I’m a Chef” Part)

1. Preheat and Prep: When you’re ready to bake, preheat your oven to 350°F (175°C). Take the casserole out of the fridge and let it sit on the counter while the oven heats up.
2. Make the Streusel: In your medium bowl, combine the flour, brown sugar, and cinnamon. Add the cold, cubed butter. Use a pastry blender or your fingertips to cut the butter into the mixture until it resembles coarse, damp sand with some pea-sized butter chunks remaining.
3. Top and Bake: Sprinkle the streusel topping evenly over the surface of the casserole. Bake, uncovered, for 45-55 minutes. It’s done when the casserole is puffed up, golden brown, and a knife inserted into the center comes out clean.
4. Rest and Serve: Let the casserole rest for about 10 minutes before slicing and serving. It’s fantastic on its own or with a drizzle of maple syrup.

Common Mistakes to Avoid (So It’s a Casserole, Not a Bread Soup)

Read this section. Your reputation as a breakfast champion depends on it.

1. Using Fresh, Soft Bread: This is the number one sin. Fresh bread will disintegrate in the custard, turning your beautiful casserole into a sad, soggy porridge. You need sturdy, day-old (or even two-day-old) bread that can stand up to the overnight soak.
2. Not Soaking it Long Enough: If you try to rush the soak, the bread won’t have time to fully absorb the custard. You’ll end up with a layer of dry bread on top and a puddle of scrambled eggs on the bottom. Let it soak for at least 8 hours, or overnight.
3. Forgetting to Rest It: Don’t slice into it the second it comes out of the oven. Letting it rest for 10 minutes allows the custard to fully set, making it much easier to slice and serve cleanly.
4. Browning Too Quickly: If you notice the streusel topping is getting too dark before the center is cooked, just lightly tent the dish with a piece of aluminum foil for the remainder of the baking time.

Variations & Customizations

This recipe is a great starting point for your own breakfast creations.

• Make it Dairy-Free: This is an easy swap! Use a sturdy dairy-free bread (like a sourdough or French loaf), substitute the milk and cream with a full-fat, creamy oat milk or cashew milk, and use cold, stick-style vegan butter for the streusel.
• Add Some Fruit: Toss 1-2 cups of chopped apples or pears in with the bread cubes before pouring over the custard for a lovely fruity addition.
• Boozy Eggnog Casserole: For an extra-festive, adults-only version, replace 1 cup of the milk with your favorite bourbon-spiked eggnog.

FAQ: Your Holiday Breakfast Queries, Answered

Let’s get those questions answered so you can bake with confidence.

1. Can I assemble and bake this on the same day?

You can, but it won’t be as good. You need to let it soak for at least 4 hours for the bread to properly absorb the custard. The overnight soak is highly recommended for the best texture.

2. How do I know when the casserole is fully cooked?

The top should be golden brown and puffed, and the center should no longer be jiggly. The most reliable test is to insert a knife or a skewer into the center—if it comes out clean (with no wet, raw egg), it’s done.

3. Can I freeze this French toast casserole?

Yes! You can freeze it baked or unbaked. To freeze unbaked, assemble it completely (without the streusel), wrap it tightly, and freeze for up to 3 months. Thaw it overnight in the fridge, then add the streusel and bake. To freeze leftovers, store them in an airtight container for up to 3 months.

4. What’s the best bread to use?

Enriched breads like challah and brioche are the best because their rich, eggy structure holds up well to the custard. A sturdy French loaf, Italian bread, or sourdough are also great options. Avoid standard sandwich bread.

5. My casserole came out dry. What went wrong?

This usually means your bread was too dry or you didn’t have enough custard to soak it all. Make sure your bread cubes are fully submerged and gently press them down into the liquid before refrigerating.

6. Can I make this gluten-free?

Yes, you can use a good quality, sturdy gluten-free bread. Just like with regular bread, make sure it’s a day or two old so it’s a bit dried out.

7. What should I serve with this?

It’s a pretty complete meal on its own! A drizzle of maple syrup is classic. You could also serve it with a side of fresh fruit, yogurt, or some crispy bacon or sausage to balance the sweetness.

Final Thoughts

And there you have it—the key to a delicious, impressive, and blissfully low-stress holiday morning. This Overnight Gingerbread French Toast Casserole is about to become your new must-have tradition. Now go enjoy that extra hour of sleep. You’ve earned it.
