Crack Breakfast Casserole is a hearty, cheesy, and totally comforting dish that brings together eggs, sausage, cheese, and a touch of creaminess in one easy bake. It’s the kind of breakfast that feels like a warm hug first thing in the morning, with fluffy eggs and gooey melted cheese all mixed with savory sausage and bread that soaks up all the good flavors.
I love making this casserole when we have friends or family over because it’s so simple to prep ahead and then just pop in the oven. What’s great is that it feels like a special treat but doesn’t take tons of time or fancy steps. I usually toss everything in the night before and let it sit in the fridge, which helps the bread soak up the eggs even better for that perfectly creamy texture when baked.
My favorite way to enjoy this crack breakfast casserole is with a little hot sauce or a side of fresh fruit to balance the rich flavors. It’s one of those dishes that gets everyone excited at the table, and honestly, it rarely lasts long because it tastes so good. If you want a breakfast that’s easy, filling, and sure to please a crowd, this is it!
Key Ingredients & Substitutions
Breakfast Sausage: This adds great flavor and protein. You can swap it with cooked bacon, ham, or even a plant-based sausage for a vegetarian option.
Eggs & Milk: Eggs provide the structure and richness. Milk helps keep the casserole moist. Use any milk you like, even dairy-free alternatives work well here.
Cheeses (Cheddar and Mozzarella): Sharp cheddar gives a nice tang, and mozzarella adds gooey stretchiness. Feel free to use Colby, Monterey Jack, or a cheese blend you prefer.
Hash Browns: These soak up the egg mixture and add texture. Fresh shredded potatoes or frozen ones both work fine—just thaw before mixing.
How Can You Make the Casserole Set Perfectly Without Getting Too Dry?
Getting the right texture is key. Here’s how:
- Grease your baking dish thoroughly to prevent sticking.
- Mix the eggs and milk well to create an even custard base.
- Let the hash browns thaw fully so they absorb the egg mixture properly.
- Bake at 350°F (175°C) and check at 45 minutes with a knife; it should come out clean but the casserole should still feel moist.
- Let the casserole cool for 5–10 mins before slicing to help it firm up without drying out.
Equipment You’ll Need
- 9×13-inch baking dish – I like this size because it fits everything evenly and cooks through nicely.
- Skillet – a large skillet makes it easy to brown the sausage and drain excess grease.
- Mixing bowls – you’ll need a couple to whisk the eggs and combine ingredients.
- Whisk or fork – to mix the egg and milk mixture smoothly.
- Measuring cups and spoons – for accurate ingredient portions.
- Grater – for shredding cheese and potatoes if you’re using fresh hash browns.
Flavor Variations & Add-Ins
- Use cooked bacon or ham instead of sausage for a different savory flavor.
- Add sautéed vegetables like bell peppers, spinach, or mushrooms for extra nutrition and color.
- Switch up the cheese: try Monterey Jack, Pepper Jack, or a Swiss blend for varied richness.
- Spice it up with hot sauce, sliced jalapeños, or a dash of smoked paprika for some heat and smoky flavor.
Crack Breakfast Casserole
Ingredients You’ll Need:
- 1 pound breakfast sausage
- 8 large eggs
- 1 cup milk
- 2 cups shredded sharp cheddar cheese
- 2 cups shredded mozzarella cheese
- 4 cups frozen hash browns, thawed or fresh shredded potatoes
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and pepper, to taste
- Optional garnish: freshly chopped parsley
How Much Time Will You Need?
From start to finish, this casserole takes about 1 hour to prepare and bake. You’ll spend around 15 minutes cooking the sausage and mixing the ingredients, then about 45 to 55 minutes baking it until golden and set. Let it rest a few minutes before serving for the best texture.
Step-by-Step Instructions:
1. Prepare the Oven and Baking Dish:
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to keep the casserole from sticking.
2. Cook the Sausage:
In a large skillet over medium heat, cook the breakfast sausage until fully browned and cooked through. Use a spatula to break it into small crumbles. Drain any extra grease, then set the sausage aside.
3. Mix the Egg Base:
In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper until smooth and well combined.
4. Combine Ingredients:
Stir in the thawed hash browns, cooked sausage, and 1 ½ cups each of cheddar and mozzarella cheese into the egg mixture. Mix everything thoroughly so all flavors come together.
5. Assemble the Casserole:
Pour the mixture evenly into the prepared baking dish. Sprinkle the remaining cheddar and mozzarella cheese on top for a melty, golden cheese crust.
6. Bake:
Bake the casserole in the oven for 45 to 55 minutes. It’s done when the center is set (a knife inserted comes out clean) and the top is bubbly and slightly browned.
7. Cool and Serve:
Remove the casserole from the oven and let it cool for a few minutes to firm up. Garnish with freshly chopped parsley if you like. Slice, serve warm, and enjoy!
Can I Use Frozen Hash Browns Without Thawing?
It’s best to thaw frozen hash browns before adding them to the casserole. Thawing helps them absorb the egg mixture evenly and ensures the casserole cooks through without excess moisture.
Can I Substitute the Sausage with Another Protein?
Absolutely! Cooked bacon, ham, or even a plant-based sausage work well as alternatives. Adjust the seasoning if needed to complement your protein choice.
How Long Can I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.
Can I Prepare the Casserole the Night Before?
Yes! Assemble the casserole the night before, cover it tightly, and refrigerate. Bake it fresh the next morning for a convenient and delicious breakfast.
