Easy Breakfast Casserole Sausage

This easy breakfast casserole recipe with sausage makes busy mornings and relaxed brunches a breeze. Each bite is hearty yet comforting thanks to layers of fluffy eggs, melty cheese, and flavorful sausage nestled over bread or hash browns. It is a breeze to prep ahead and delivers that golden baked finish every time you pull it from the oven.

Every time I make this on weekends, I love how the kitchen fills with a cozy aroma and my family wakes up hungry for that first slice. The best part is there are always leftovers for busy weekdays.

Gather Your Ingredients

• Large eggs: Bring rich flavor and the structure that helps the casserole set beautifully. Opt for fresh eggs, and room temperature eggs blend best.
• Breakfast sausage: Turkey or chicken sausage adds flavor and a hearty texture. Choose a quality sausage with balanced seasoning or mild spice.
• Bread cubes or shredded hash browns: Form the foundation. Day old bread absorbs the mixture perfectly while hash browns give a crispier texture.
• Milk: Helps bind everything together and boosts creaminess. Use whole milk or a richer variety for a silkier finish.
• Shredded cheese: Cheddar, mozzarella, or a blend brings gooey melt and flavor. Freshly shredded cheese melts better than pre-shredded.
• Salt and pepper to taste: Accentuate the flavors. Freshly cracked pepper gives a nice bite.
• Diced bell peppers or onions: For colorful crunch and sweet flavor. Choose crisp produce for the best texture.
• Spinach or mushrooms: Add earthy flavor and extra nutrition. Use fresh and make sure to sauté moisture out from mushrooms.
• Garlic powder or paprika: Brings subtle warmth or a smoky note.
• Chopped parsley for garnish: Adds freshness and color. Choose vibrant green parsley for the final sprinkle.

How to Make It

Prep the Oven and Dish:

Set your oven to 350 degrees Fahrenheit or 175 degrees Celsius. Lightly grease a baking dish with butter or spray to keep the casserole from sticking later.

Brown and Drain the Sausage:

Cook your sausage in a skillet over medium heat until browned well and deeply savory. Break it into crumbles as it cooks. Drain off any excess fat for a lighter texture.

Mix the Egg Base:

In a large bowl whisk together eggs and milk until smooth and glossy. Add salt, pepper, seasonings and whisk again until everything is well combined.

Layer the Ingredients:

Arrange your bread cubes or hash browns in the bottom of your greased baking dish. Spoon the cooked sausage and any prepared vegetables evenly across the surface so every bite is balanced.

Pour and Soak:

Slowly pour the egg mixture over the layers in the baking dish. Give the dish a gentle shake or tap so the egg seeps into every nook for uniform texture once baked.

Add the Cheese:

Sprinkle shredded cheese generously over the top ensuring even coverage for bubbly golden melt.

Bake to Perfection:

Place the casserole in the center rack and bake for about 35 to 40 minutes. Check that the center is set and the edges are golden brown for best results.

Rest and Serve:

Remove from the oven and let the casserole cool for five to ten minutes. This resting time makes slicing easier and keeps the layers intact. Finish with a sprinkle of fresh parsley and serve warm.

Cheddar is my favorite cheese because it melts so perfectly and gets those caramelized edges. The first time I made this everyone fought for the corners just for that extra crispy cheese crunch.

Flavor Boosters

Try chicken or plant based sausage for a lighter twist. Non dairy milk and vegan cheese work for allergen free needs. Stale baguette or even croissants make a rich alternative to sandwich bread.

Serving Suggestions

Serve with a simple green salad or fresh fruit for a balanced meal. Add a dollop of salsa or hot sauce to amp up the flavor. Pair with coffee or orange juice for a complete breakfast spread.

Creative Twists

In spring add fresh herbs or asparagus for a vibrant touch. In summer fold in chopped tomatoes or sweet corn kernels. In winter choose root vegetables or roasted mushrooms.

I always assemble my casserole the night before and give it time in the refrigerator. This lets the bread fully soak up those eggs and makes the morning oven time a breeze.
