Ingredients You’ll Need

Gather ’round, pantry warriors! Here’s your hit list. Don’t sweat it if you’re missing something; we’re all about flexibility here.

• **6-8 slices day-old bread:** The slightly stale kind is perfect. Think sourdough, challah, brioche, or even just regular sandwich bread. We’re not building a gourmet castle, but we want it to soak up all the good stuff without turning into mush.
• **6 large eggs:** The glorious glue that holds our breakfast dreams together.
• **2 cups whole milk:** Because we’re not counting calories before our first coffee, are we? Any milk works, honestly, but whole milk gives it that extra richness.
• **½ cup granulated sugar:** Just enough sweetness to make it feel like a treat.
• **1 teaspoon vanilla extract:** For that “fancy bakery” smell that will make your neighbours jealous.
• **½ teaspoon ground cinnamon:** The spice of life, and definitely the spice of breakfast.
• **¼ teaspoon salt:** Don’t skip this! It balances out the sweetness.
• **2 tablespoons unsalted butter, melted:** For greasing the dish. Or salted, if you live dangerously.
• **Optional Add-ins (choose your adventure!):**
  • **1 cup fresh or frozen berries:** Blueberries, raspberries, mixed berries – whatever your heart desires.
  • **½ cup chocolate chips:** Because why not? It’s breakfast, not a diet plan.
  • **¼ cup chopped nuts:** Pecans or walnuts add a nice crunch.

Step-by-Step Instructions

1. **Prep the Bread:** Tear or cut your day-old bread into 1-inch cubes. Don’t be too precious about it; rustic is charming. Toss these golden nuggets into a buttered 9×13 inch baking dish. Make sure the dish is well-buttered to prevent sticking – trust me on this.
2. **Whisk the Wet Stuff:** In a large bowl, whisk together the eggs, milk, sugar, vanilla extract, cinnamon, and salt until everything is beautifully combined. It should look like a pale yellow, slightly frothy potion.
3. **Drench and Distribute:** Pour the egg mixture evenly over the bread cubes in your baking dish. Make sure all the bread gets a good soak! Gently press down on any rebellious bread pieces trying to escape the liquid.
4. **Add Your Extras (if using):** Sprinkle your chosen berries, chocolate chips, or nuts over the top. Don’t be shy!
5. **The Overnight Chill:** Cover the baking dish tightly with plastic wrap or foil. Pop it in the fridge and let it chill out for at least 8 hours, or up to 24 hours. This is where the magic happens, allowing the bread to fully absorb all those delicious flavours.
6. **Morning Glory (Bake Time!):** When you’re ready for breakfast, preheat your oven to 350°F (175°C). Remove the casserole from the fridge and let it sit on the counter for about 15-20 minutes while the oven heats up.
7. **Bake It Up:** Uncover the casserole and bake for 45-55 minutes, or until it’s golden brown on top and set in the center. A knife inserted into the middle should come out clean. **No jiggle, no problem!**
8. **Rest and Serve:** Let the casserole rest for 5-10 minutes before serving. This helps it firm up a bit and prevents you from burning your tongue (rookie mistake!). Serve with a dusting of powdered sugar, a drizzle of maple syrup, or a dollop of whipped cream.

Common Mistakes to Avoid

Nobody’s perfect, but we can at least try to avoid these common breakfast casserole blunders:

• **Using Fresh, Soft Bread:** Resist the urge! Fresh bread can turn mushy and soggy. Day-old (or even lightly toasted fresh bread) is key for a good texture.
• **Not Letting it Soak Long Enough:** If you rush the soaking, you’ll end up with dry spots and a less flavourful casserole. **Patience is a virtue, especially here.**
• **Overbaking:** Keep an eye on it! Overbaking can lead to rubbery, sad eggs. You want it set, but still custardy.
• **Not Greasing the Dish:** Seriously, do it. Cleaning a stuck-on casserole is no fun.
• **Eating it Straight Out of the Oven:** It will be lava-hot. Give it a few minutes to cool down and set, or suffer the consequences (burnt tongue, sad face).

Alternatives & Substitutions

Got a rebel spirit? Want to mix things up? I dig it! Here are some ideas:

• **Bread Choices:** Instead of basic bread, try brioche for extra richness, challah for a slightly sweet chewiness, or even cinnamon swirl bread for an added flavour boost. IMO, brioche takes it up a notch!
• **Milk Matters:** Any milk works! Almond, soy, oat, skim – just be aware it might alter the richness slightly.
• **Sweetener Swap:** Maple syrup or honey can replace the granulated sugar for a different kind of sweetness. Reduce the amount slightly if using a liquid sweetener.
• **Amp Up the Add-ins:** Get wild! Try chopped apples, peaches, shredded coconut, cream cheese dollops, or even a handful of crumbled bacon (for a sweet and savoury twist – trust me!).
• **Go Savoury:** Skip the sugar, vanilla, and cinnamon. Add shredded cheese (cheddar, Gruyere), cooked sausage, ham, or sautéed veggies (onions, bell peppers, spinach). You’ll need to increase the salt and maybe add some black pepper. It’s a whole new world!

FAQ (Frequently Asked Questions)

Got questions? I’ve got answers. (Mostly.)

Q: Can I use margarine instead of butter?
A: Well, technically yes, but why hurt your soul like that? Butter just tastes better, let’s be honest. But if it’s all you have, it’ll work.

Q: How long can it chill in the fridge?
A: Up to 24 hours is ideal. Any longer and the bread might start to break down too much. Don’t push it beyond that, it might stage a soggy protest.

Q: Can I make it without soaking overnight?
A: You *can* get away with letting it soak for at least an hour before baking, but overnight is where the magic truly happens. The bread fully saturates, leading to a much better texture and flavour, FYI.

Q: How do I know it’s done?
A: It should be golden brown on top and feel set in the center when you gently shake the dish. A knife inserted into the middle should come out clean. No jiggle, no problem!

Q: Can I freeze leftovers?
A: Absolutely! Once cooled, cut it into individual portions, wrap them tightly, and freeze for up to a month. Reheat in the microwave or oven.

Q: What if I don’t have day-old bread?
A: No worries! Cut fresh bread into cubes and spread them on a baking sheet. Bake at 300°F (150°C) for 10-15 minutes, or until lightly toasted and dried out. Let cool completely before using.
