Crack Breakfast Casserole is the ultimate easy and tasty morning dish that brings together eggs, cheese, sausage, and a delicious crunch from buttery crackers on top. This casserole is all about simple ingredients working together to create a warm, hearty meal that everyone loves. It’s perfect for busy mornings or when you want to feed a crowd without a lot of fuss.
I love making this casserole the night before, so it has time to soak all those flavors together while I’m sleeping. The buttery cracker layer on top adds such a fun texture that keeps each bite exciting. Plus, it’s a no-brainer to customize—sometimes I toss in some veggies or swap out the sausage for bacon depending on what’s in the fridge. It makes mornings so much easier and way more satisfying.
Whenever I serve this for brunch, everyone always asks for seconds. I like to pair it with fresh fruit or a simple green salad to balance out the richness. It’s one of those recipes that feels like a special treat but is really just a clever, straightforward way to start the day with something warm and comforting. I guarantee it’ll become a go-to dish in your household, just like it did in mine!
Key Ingredients & Substitutions
Breakfast sausage: This adds savory flavor and protein. You can swap pork sausage for turkey sausage or even cooked bacon if you prefer a leaner or smokier option.
Eggs: Eggs hold the casserole together and make it fluffy. Use large eggs for best texture, or try egg whites to lighten the dish.
Sharp cheddar cheese: Sharp cheddar brings a nice tang and melts beautifully. Feel free to switch to Colby Jack, Monterey Jack, or even a mild mozzarella for a different taste.
White bread: Cubed white bread soaks up the egg mixture, giving a soft, custardy texture. You can use whole wheat, sourdough, or even a gluten-free bread if needed.
Whole milk and melted butter: These help create a rich, creamy custard. Substitute milk with any plant-based milk (unsweetened) and butter with oil or margarine for dairy-free options.
How Do I Make Sure the Casserole Bakes Perfectly and Isn’t Soggy?
Getting the custard set right without sogginess can be tricky. Here’s what I do:
- First, cook the sausage fully and drain fat well to avoid excess grease.
- Cut the bread into cubes and spread evenly. Using slightly stale bread helps it soak but not fall apart.
- Whisk the eggs and milk thoroughly to combine for a smooth custard.
- Pour the liquid mixture evenly over bread and sausage so everything absorbs it well.
- Bake uncovered at 350°F for about 45-50 minutes. The top should turn golden, and the casserole should feel firm but still tender.
- Let it cool 5 minutes before slicing—this helps it finish setting and makes clean slices easier.
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for even cooking and easy serving.
- Large skillet – cooks sausage thoroughly and lets you drain excess fat.
- Mixing bowl – big enough to whisk eggs, milk, and spices smoothly.
- Whisk – helps blend the custard ingredients evenly for a creamy texture.
- Measuring cups and spoons – to get your ingredients just right every time.
Flavor Variations & Add-Ins
- Swap breakfast sausage for diced ham or cooked bacon to change up the meat flavor.
- Add chopped bell peppers or spinach for a fresh, colorful veggie boost.
- Try pepper jack cheese instead of cheddar if you want a little spicy kick.
- Mix in sautéed mushrooms or caramelized onions for extra depth and sweetness.

How Much Time Will You Need?
This recipe takes about 15 minutes of prep time, plus 45-50 minutes to bake. Allow an additional 5 minutes for cooling before serving. Overall, about 1 hour from start to finish.
Step-by-Step Instructions:
1. Prepare and Cook the Sausage:
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray. In a large skillet, cook the breakfast sausage over medium heat until it’s browned and crumbly. Drain off any excess fat and set the sausage aside.
2. Mix the Egg Custard:
In a large bowl, whisk together the eggs, whole milk, melted butter, garlic powder, onion powder, salt, and pepper until everything is well combined and smooth.
3. Assemble the Casserole:
Spread the cubed white bread evenly into the greased baking dish. Sprinkle the cooked sausage over the bread cubes. Pour the egg mixture evenly across the sausage and bread. Finally, sprinkle the shredded cheddar cheese evenly on top.
4. Bake and Serve:
Bake the casserole uncovered for 45-50 minutes, or until the egg custard is set and the top is golden brown. Remove from the oven and let the casserole cool for about 5 minutes. Garnish with freshly chopped chives or green onions before slicing and serving warm. Enjoy!
Can I Make Crack Breakfast Casserole Ahead of Time?
Yes! You can assemble the casserole the night before, cover it tightly, and refrigerate. When ready to bake, just add a few extra minutes to the baking time since it will be cold.
Can I Use Frozen Sausage?
Absolutely, but be sure to fully thaw the sausage in the fridge before cooking. This helps it brown evenly and prevents excess moisture in the casserole.
How Should I Store Leftovers?
Store leftover casserole in an airtight container in the fridge for up to 3 days. Reheat individual slices in the microwave or oven until warmed through.
What Can I Substitute for White Bread?
You can use whole wheat, sourdough, or even gluten-free bread cubes. Slightly stale bread works best to soak up the egg mixture without becoming too mushy.
