Ingredients You’ll Need

Gather ’round, fellow food enthusiasts! Here’s your shopping list for breakfast glory:

• **6-8 slices bread:** Stale bread is actually your friend here – Texas toast, challah, brioche, or even just regular sandwich bread. Tear it into bite-sized pieces.
• **1 lb breakfast sausage or bacon:** Cooked and crumbled or diced. If you’re using bacon, cook it crispy and crumble it up.
• **1 small onion:** Diced. For that subtle flavor punch.
• **1 bell pepper:** Any color, diced. Adds a bit of sweetness and crunch.
• **1 ½ cups shredded cheese:** Sharp cheddar is my go-to, but mix it up! Monterey Jack, Gruyere, or even a spicy pepper jack work wonders.
• **8 large eggs:** The main event, folks.
• **2 cups milk:** Whole milk for richness, or whatever moo-juice you have handy.
• **1 tsp salt:** Don’t be shy.
• **½ tsp black pepper:** Freshly ground, if you’re feeling fancy.
• **1 tsp dry mustard (optional):** Our little secret flavor weapon. Trust me, it makes a difference without tasting like mustard.
• **Butter or cooking spray:** For greasing your dish.

Step-by-Step Instructions

1. **Prep the Pad:** Generously grease a 9×13 inch baking dish with butter or cooking spray. Tear your bread into bite-sized pieces and spread them out evenly in the dish.
2. **Cook the Goodies:** Brown your sausage or bacon in a skillet. Drain any excess fat. Add your diced onions and bell pepper to the same skillet (or clean it first if there’s too much grease) and sauté until they’re soft and fragrant. Scatter them over the bread in the baking dish.
3. **Cheesy Layer:** Sprinkle about half of your shredded cheese over the bread, sausage/bacon, and veggies. This is where the magic starts to happen.
4. **Eggcellent Mix:** In a large bowl, whisk together the eggs, milk, salt, pepper, and that optional dry mustard. Whisk it good until everything’s blended and a little frothy.
5. **Soak It Up:** Pour the egg mixture evenly over all the contents in the dish. Make sure all the bread gets a good soak – push it down gently if needed.
6. **Top It Off:** Sprinkle the remaining cheese on top. Cover the dish tightly with plastic wrap.
7. **Chill Out (Literally):** Pop your covered casserole into the fridge overnight, or for at least 4 hours. This step is **crucial** for the bread to absorb all that eggy goodness and for the flavors to meld.
8. **Morning Glory:** The next morning, pull the casserole out of the fridge at least 30 minutes before baking to take off the chill. Preheat your oven to 375°F (190°C).
9. **Bake Away:** Remove the plastic wrap and bake for 45-60 minutes, or until it’s golden brown, puffed up, and a knife inserted into the center comes out clean.
10. **Rest & Serve:** Let it rest for 5-10 minutes before slicing and serving. This helps it set up nicely and prevents a crumbly mess. Enjoy your masterpiece!

Common Mistakes to Avoid

Don’t worry, we’ve all made these! But now you’re armed with knowledge, so you won’t:

• **Skimping on soaking time:** Ever wonder why your casserole is dry and sad? Not letting it chill overnight is probably why. **Don’t rush the soak!** It’s the secret to a custardy texture.
• **Not preheating the oven:** Rookie mistake! Cold oven = uneven cooking and a longer bake time. Give your oven a minute to warm up, will ya?
• **Over-mixing the eggs:** Whisk until combined, not until your arm falls off. Too much air can make your casserole rubbery instead of fluffy. We want delicious, not bouncy!
• **Forgetting to grease the dish:** Unless you enjoy a good scraping session (and I doubt you do), grease that baking dish generously. Trust me, future you will thank present you.

Alternatives & Substitutions

This recipe is super forgiving! Feel free to play mad scientist with your ingredients:

• **Meatless Marvel:** Skip the sausage/bacon and load up on veggies! Spinach, mushrooms, sun-dried tomatoes, or even roasted sweet potatoes work wonders.
• **Cheese Whiz:** Don’t fancy cheddar? Use Gruyere for a sophisticated touch, Colby Jack for mildness, or Feta for a tangy surprise. Mix and match, **IMO!**
• **Bread Talk:** Brioche makes it super rich and custardy. Sourdough adds a nice tang. Got leftover croissants? Tear ’em up! Almost any bread will do the trick.
• **Spice it Up:** A dash of hot sauce in the egg mixture? Smoked paprika? A pinch of cayenne? Go on, live a little!

FAQ (Frequently Asked Questions)

• **Can I make this sweet instead of savory?** Absolutely! Ditch the meat/cheese, add cinnamon, nutmeg, a little brown sugar, and some berries. Top with streusel! Hello, French Toast Casserole!
• **How long does it last in the fridge (uncooked)?** You can assemble it up to 24 hours in advance. Beyond that, the bread might get a bit too mushy.
• **Can I freeze it?** Cooked, yes! Let it cool completely, then wrap individual slices or the whole casserole tightly. Reheat from frozen in the oven. Uncooked? Not recommended, the texture can get weird.
• **What if I don’t have stale bread?** Just lightly toast fresh bread slices in the oven for 10-15 minutes until somewhat dry, then tear. Easy peasy.
• **My casserole is jiggly in the middle, but the edges are done. Help!** Ovens vary, so be patient! Cover the edges with foil to prevent over-browning and keep baking until the center is set and a knife comes out clean.
• **Can I use egg whites only?** You *can*, but you’ll lose some of that richness and tenderness that whole eggs provide. For a lighter version, try a mix of whole eggs and whites. But really, why deny yourself the glorious yolk?
