Ingredients

For this delectable Crack Breakfast Casserole, you’ll need:

• 1 pound (450g) breakfast sausage, mild or spicy
• 1 medium onion, finely diced (about 1 cup)
• 1 red bell pepper, diced (about 1 cup)
• 3 cloves garlic, minced
• 8 large eggs
• 1 cup (240ml) whole milk
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon paprika
• 1 package (30oz/850g) frozen hash browns, thawed
• 2 cups (8oz/225g) sharp cheddar cheese, shredded
• 1 cup (4oz/113g) Monterey Jack cheese, shredded
• 8 slices bacon, cooked and crumbled
• 3 green onions, thinly sliced

The quality of your sausage makes a significant difference in this sausage breakfast casserole—opt for a premium brand with good fat content for maximum flavor. For the hash browns, squeeze out excess moisture after thawing to ensure a crispy rather than soggy base. Freshly shredded cheese melts more smoothly than pre-packaged varieties, creating that perfect cheesy pull when served.

Pro Tips

Master the Pre-Cook: Always brown your sausage completely before adding it to the casserole. This crucial step develops deep flavor compounds through the Maillard reaction and renders excess fat that would otherwise make your Crack Breakfast Casserole greasy. Cook the sausage until it’s nicely caramelized, then remove it with a slotted spoon, leaving behind about 1 tablespoon of fat to sauté your vegetables.

Proper Egg Mixture Technique: When combining your eggs and milk, whisk vigorously until the mixture becomes slightly frothy. This incorporation of air creates a fluffier texture in the final casserole. Room temperature eggs incorporate more readily than cold ones, so set them out about 30 minutes before preparation. Add your seasonings directly to the egg mixture rather than sprinkling them on top to ensure even distribution throughout the casserole.

Layering Strategy: The secret to a perfectly textured overnight breakfast casserole lies in proper layering. Start with a base of well-dried hash browns (excess moisture is the enemy of crispness). Press them firmly into the baking dish to create a solid foundation. Add your protein layer next, followed by vegetables, and finally top with cheese. This strategic layering ensures that each ingredient cooks properly and creates distinct texture zones in your finished Crack Breakfast Casserole.

Instructions

Step 1
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or cooking spray. In a large skillet over medium-high heat, cook the breakfast sausage, breaking it apart with a wooden spoon until it’s nicely browned and no pink remains, about 5-7 minutes. The caramelization on the sausage adds incredible depth to your Crack Breakfast Casserole, so don’t rush this step.

Step 2
Drain all but 1 tablespoon of fat from the skillet. Add the diced onion and bell pepper to the remaining fat and sauté until softened, about 4 minutes. Add the minced garlic and cook for 30 seconds more until fragrant. Remove the vegetable and sausage mixture from heat and let it cool slightly. This cooling period prevents the hot mixture from cooking the eggs prematurely when combined.

Step 3
In a large bowl, whisk together the eggs, milk, salt, pepper, and paprika until well combined and slightly frothy. The vigorous whisking incorporates air that will help create a fluffy texture in your breakfast casserole recipe. Set this mixture aside while you prepare the base.

Step 4
Place the thawed hash browns in a clean kitchen towel and squeeze out as much moisture as possible. This crucial step ensures your casserole base will be crispy rather than soggy. Spread the dried hash browns evenly in the prepared baking dish, pressing them down gently to form a compact layer.

Step 5
Sprinkle half of the cheddar and Monterey Jack cheeses over the hash browns. Top with the cooled sausage and vegetable mixture, distributing it evenly across the surface. Add the crumbled bacon, reserving a small amount for garnish if desired.

Step 6
Pour the egg mixture slowly and evenly over the layers, allowing it to seep down into the casserole. Top with the remaining cheese and a sprinkle of paprika for color. At this point, you can either bake immediately or cover and refrigerate overnight for a convenient make-ahead breakfast casserole.

Step 7
Bake uncovered for 45-50 minutes until the center is set and the top is golden brown and bubbly. If the top begins to brown too quickly, cover loosely with foil. Allow your Crack Breakfast Casserole to rest for 10 minutes before serving. This resting period allows the casserole to set properly and makes serving cleaner and easier. Garnish with sliced green onions and the reserved bacon bits before serving.

Variations

Southwestern Crack Casserole: Transform your Crack Breakfast Casserole with Tex-Mex flavors by substituting chorizo for breakfast sausage and adding 1 cup of diced green chiles, 1 teaspoon of cumin, and 1/2 teaspoon of chili powder. Top with pepper jack cheese instead of Monterey Jack and garnish with fresh cilantro, avocado slices, and a dollop of sour cream. This variation brings a delightful heat and south-of-the-border flair to your breakfast table.

Veggie Lover’s Option: Create a vegetarian version by omitting the meat entirely and doubling up on vegetables. Add sautéed mushrooms, spinach, and roasted cherry tomatoes for a garden-fresh take. The umami from the mushrooms provides a satisfying depth that makes the meat less missed. For extra protein, incorporate 1 cup of small-diced firm tofu sautéed with a tablespoon of soy sauce into your breakfast casserole recipe.

Italian-Inspired Version: For an Italian twist, use Italian sausage instead of breakfast sausage and add 1/2 cup of sun-dried tomatoes, 1 tablespoon of Italian seasoning, and substitute mozzarella and parmesan for the cheddar and Monterey Jack. This Mediterranean variation offers a sophisticated flavor profile that works beautifully for brunch gatherings or a breakfast-for-dinner option.

Storage and Serving

This Crack Breakfast Casserole stores beautifully, making it perfect for meal prep. Once completely cooled, cover leftovers tightly with plastic wrap or transfer to airtight containers and refrigerate for up to 4 days. For longer storage, cut the casserole into individual portions, wrap each piece in plastic wrap followed by foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

To reheat, warm individual portions in the microwave for 1-2 minutes until heated through. For the best texture, reheat larger portions in a 325°F oven for 15-20 minutes, or until warmed to your liking. A quick minute under the broiler can help restore some crispness to the top.

For serving, pair this hearty overnight breakfast casserole with a light arugula salad dressed with lemon vinaigrette for a delightful contrast to the rich casserole. For a classic brunch spread, serve alongside fresh fruit, warm biscuits, and mimosas. During holiday mornings, complement it with sweet offerings like cinnamon rolls or banana bread for a balanced breakfast buffet that will please everyone.

FAQs

Can I make this Crack Breakfast Casserole ahead of time?
Absolutely! This is the perfect make-ahead breakfast casserole. Prepare everything up to the baking stage, cover tightly with plastic wrap, and refrigerate overnight. In the morning, remove from the refrigerator 30 minutes before baking to take the chill off, then bake as directed, adding about 5-10 extra minutes to the cooking time.

What can I substitute for hash browns?
You can use tater tots, shredded fresh potatoes (squeezed dry), or even seasoned croutons as your base. For a lower-carb option, try shredded cauliflower that has been thoroughly dried.

Excess moisture is usually the culprit. Make sure to thoroughly drain your cooked sausage, squeeze all moisture from the hash browns, and avoid adding watery vegetables without sautéing them first.
