Crack Breakfast Casserole is a simple, hearty dish that brings together eggs, cheese, sausage, and bread in a creamy, baked comfort meal. It’s the kind of breakfast that feels like a warm hug on a lazy morning, with melty cheese and savory sausage making every bite satisfying.
I love making this casserole when I have friends or family over because it’s easy to prepare ahead of time and then pop in the oven while I enjoy some coffee. The best part for me is how the bread soaks up the egg mixture just perfectly, giving it a soft, almost custard-like texture that everyone seems to love.
My favorite way to serve this is right out of the oven with a little fresh fruit or a side of crispy bacon. It feels like such a treat and always gets everyone talking about how good it is. If you’re looking for a no-fuss breakfast that fills the room with cozy smells and happy smiles, this is a winner.
Key Ingredients & Substitutions
Breakfast Sausage: This adds great flavor and richness. If you want to cut down on fat, try turkey sausage or a plant-based sausage alternative. Cooking it well and draining excess grease keeps the casserole from feeling heavy.
Eggs and Milk: Eggs bind everything together and give the casserole its creamy texture. Whole milk works best for richness, but you can use 2% or a dairy-free milk like oat or almond if needed.
Hash Brown Potatoes: Frozen shredded hash browns are convenient and help give the casserole a hearty base. You can swap for cubed fresh potatoes if you prefer, but cook them first to soften.
Cheddar Cheese: This cheese melts beautifully and provides that classic sharp flavor. For a milder taste, use Monterey Jack or mozzarella. Mixing cheeses is fun and tasty too!
Parmesan Cheese: Adds a nice salty, nutty finish on top. If you don’t have Parmesan, try Pecorino Romano or omit it—it’s still great without.
How Do You Make Sure the Casserole Sets Perfectly and Doesn’t Get Watery?
A solidly set casserole with creamy but not runny texture is key here. Follow these tips:
- Cook the sausage well: This reduces extra grease. Drain it so the casserole won’t be soggy.
- Use thawed or fresh hash browns: If frozen, let them thaw and drain any liquid to avoid excess moisture.
- Mix eggs and milk thoroughly: Whisk until smooth so the custard cooks evenly.
- Bake long enough: Test doneness by inserting a knife or toothpick in the center — it should come out clean.
- Let it rest: Cooling for 5-10 minutes helps the casserole finish setting and makes slicing cleaner.
These steps ensure your casserole will slice nicely and taste just right every time.
Equipment You’ll Need
- 9×13 inch baking dish – A standard size that fits all the ingredients comfortably and bakes evenly.
- Skillet or frying pan – For cooking the sausage until browned and crumbly, making it flavorful and crispy.
- Whisk – To mix the eggs and milk smoothly for a creamy custard base.
- Measuring cups and spoons – For accurately measuring ingredients, especially cheese and seasonings.
- Grater – To shred the cheddar cheese easily and evenly distribute the cheese throughout the casserole.
Flavor Variations & Add-Ins
- Try different cheeses: Swap cheddar for Monterey Jack, pepper jack, or a blend for varying flavor profiles.
- Add vegetables: Sautéed bell peppers, spinach, or mushrooms add color and extra nutrients.
- Use different proteins: Replace sausage with cooked bacon, ham, or turkey for a different savory note.
- Spice it up: Mix in hot sauce, red pepper flakes, or paprika for a little extra kick.
Crack Breakfast Casserole
Ingredients You’ll Need:
- 1 pound breakfast sausage
- 6 large eggs
- 2 cups whole milk
- 4 cups frozen hash brown potatoes (shredded)
- 2 cups shredded cheddar cheese, divided
- 1/2 cup grated Parmesan cheese
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon garlic powder
- Optional garnish: chopped fresh parsley or chives
Time Needed
This recipe takes about 15-20 minutes to prepare plus 45-55 minutes to bake. After baking, allow 5-10 minutes for the casserole to rest before serving.
Step-by-Step Instructions:
1. Prepare Your Oven and Sausage
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish to prevent sticking. In a skillet over medium heat, cook the breakfast sausage until it’s evenly browned and fully cooked. Break up any large pieces as it cooks. Once done, drain any excess grease and set the sausage aside.
2. Mix the Eggs and Milk
In a large mixing bowl, whisk together the eggs, whole milk, salt, pepper, and garlic powder until the mixture is smooth and well combined.
3. Layer the Ingredients
Spread the frozen hash brown potatoes evenly over the bottom of your prepared baking dish. Next, sprinkle the cooked sausage evenly on top of the potatoes. Then, add about 1½ cups of the shredded cheddar cheese over the sausage.
4. Add the Egg Mixture and Final Cheese Topping
Carefully pour the egg and milk mixture over the layered ingredients, making sure it’s distributed evenly. Sprinkle the grated Parmesan cheese over the top, followed by the remaining cheddar cheese.
5. Bake and Rest
Place the casserole in the preheated oven and bake for 45-55 minutes, or until the casserole is set in the middle and the top is golden brown. Remove from the oven and let it rest for 5-10 minutes to help it set and make it easier to serve.
6. Serve
Optional: Garnish with chopped fresh parsley or chives for a splash of color and fresh flavor. Serve warm and enjoy a delicious, comforting breakfast!
Can I Use Frozen Sausage Instead of Fresh?
Yes, you can use frozen sausage, but make sure to thaw it completely before cooking. Thaw in the fridge overnight or use the microwave’s defrost setting, then cook as usual to avoid uneven cooking.
Can I Make This Casserole Ahead of Time?
Absolutely! Assemble the casserole the night before and keep it covered in the fridge. In the morning, just bake it a little longer—around 55-65 minutes—until fully set and golden.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through to keep the texture delicious.
What Can I Substitute for Hash Browns?
If you don’t have hash browns, you can use cubed or shredded potatoes that have been cooked and drained well. Sweet potatoes or even diced cooked vegetables like zucchini can also work for a twist.
