What You’ll Need

For the Casserole:

1 pound breakfast sausage (pork, turkey, or chicken)
1 medium onion, diced
1/2 cup bell pepper, diced (optional)
4 cups frozen hash browns (shredded or diced)
8 large eggs
1 cup milk (whole, 2%, or dairy-free alternative)
2 cups shredded cheese (cheddar, Monterey Jack, or a blend)
1 teaspoon garlic powder
1/2 teaspoon onion powder
Salt and pepper, to taste
1/4 teaspoon paprika (optional)

Optional Toppings:

Chopped green onions
Extra shredded cheese
Salsa or hot sauce for serving

Step-by-Step Instructions

Step 1: Cook the Sausage

In a large skillet over medium heat, cook the breakfast sausage until browned and fully cooked, breaking it apart with a spoon as it cooks. Drain any excess grease if necessary.

Add the diced onion (and bell pepper if using) to the skillet and sauté for 3–4 minutes until softened. Remove from heat and let cool slightly.

Step 2: Prepare the Egg Mixture

In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, pepper, and paprika until well combined. This will create the creamy custard base for your casserole.

Step 3: Assemble the Casserole

Grease a 9×13-inch baking dish lightly with cooking spray or butter.
Spread the frozen hash browns evenly on the bottom of the dish.
Sprinkle the cooked sausage and onion mixture over the hash browns.
Top with 1 1/2 cups of shredded cheese.
Pour the egg mixture evenly over the layers, making sure all ingredients are covered.

Tip: Press down lightly with a spatula to ensure the eggs soak through the hash browns for an even texture.

Step 4: Bake the Casserole

Preheat your oven to 375°F (190°C).
Cover the baking dish with foil and bake for 30 minutes.
Remove the foil and bake for an additional 15–20 minutes, or until the eggs are set and the top is golden brown.
If desired, sprinkle the remaining 1/2 cup of cheese on top during the last 5 minutes of baking for an extra cheesy finish.

Step 5: Cool and Serve

Allow the casserole to cool for 5–10 minutes before slicing.
Serve warm, topped with green onions, salsa, or your favorite hot sauce.

Tips for the Perfect Crack Breakfast Casserole

Use thawed or frozen hash browns.
Frozen hash browns save time, but slightly thawed ones bake more evenly.
Don’t overmix the eggs.
Whisking gently ensures a tender, fluffy custard rather than rubbery eggs.
Adjust seasoning to taste.
Feel free to add extra spices, herbs, or a pinch of cayenne for heat.
Add veggies for color and nutrition.
Mushrooms, zucchini, or spinach can be added to the sausage mixture.
Cheese makes it addictive.
Use a blend of sharp cheddar and mild Monterey Jack for depth of flavor.
Let it rest before slicing.
This prevents the casserole from falling apart and makes for cleaner portions.

Flavor Variations

Savory Twists

Bacon and Cheese:
Replace the sausage with crispy bacon and mix in your favorite cheese.

Italian Style:
Use cooked Italian sausage, diced tomatoes, and mozzarella cheese. Add Italian seasoning for extra flavor.

Southwest Casserole:
Add black beans, corn, diced jalapeños, and top with pepper jack cheese.

Vegetable Lover:
Increase bell peppers, mushrooms, zucchini, or spinach for a hearty veggie version.

Serving Suggestions

Serve your crack breakfast casserole with:

Toast or warm gluten-free bread
Fresh fruit or fruit salad
Salsa, guacamole, or hot sauce
A simple green salad for a brunch twist
Hash browns or breakfast potatoes for extra indulgence

This casserole is hearty enough to stand alone but also pairs beautifully with light sides.

How to Store and Reheat

Refrigerator:

Store leftovers in an airtight container for up to 4 days.
Reheat slices in the microwave for 30–60 seconds or in a 350°F (175°C) oven for 10 minutes until warm.

Freezer:

Cool completely, then wrap tightly in foil or place in freezer-safe containers.
Freeze for up to 2 months.
To reheat, thaw overnight in the refrigerator and bake at 350°F (175°C) for 15–20 minutes until heated through.

Make-Ahead Option

You can assemble the casserole the night before:

Prepare the sausage, onion, and egg mixture.
Layer hash browns, sausage, cheese, and pour the eggs over the top.
Cover and refrigerate overnight.
Bake the next morning as directed — perfect for stress-free brunches or holiday mornings.

Troubleshooting

Eggs not set in the center:
Bake a few extra minutes and check with a toothpick until it comes out clean.

Casserole too watery:
Use slightly thawed, not fully frozen, hash browns and drain excess sausage grease before assembling.

Top not browning:
Remove foil during the last 10–15 minutes of baking and broil briefly if needed.

Casserole falling apart:
Let it rest 5–10 minutes before slicing to allow the custard to firm up.
