Ingredients You’ll Need
Each ingredient is carefully chosen to create layers of flavor and texture in every bite. Here’s what you’ll need:
- 1 lb ground breakfast sausage – mild or spicy depending on your preference
- 6 large eggs – the base of your custard
- 2 cups whole milk – adds richness and keeps the casserole moist
- 1 ½ cups shredded cheddar cheese – for that gooey, melty top layer
- 6 slices white bread, cubed – forms the casserole’s structure and soaks up the custard
- ½ tsp salt – to enhance all the flavors
- ½ tsp black pepper – for a bit of warmth
- Optional: Chopped green onions or herbs for garnish
Step-by-Step Instructions
This dish comes together in just a few simple steps, making it perfect for beginners or seasoned home cooks alike.
Step 1: Cook the Sausage
In a large skillet over medium heat, cook the sausage until browned and fully cooked through. Use a spoon to break it up into crumbles as it cooks. Once done, drain the excess grease and set the sausage aside.
Tip: Want to boost flavor? Sauté some chopped onions or bell peppers with the sausage.
Step 2: Prepare the Egg Mixture
In a large bowl, whisk together the eggs, milk, salt, and pepper until smooth. This will become your custard base, which binds the whole casserole together.
Step 3: Assemble the Casserole
Lightly grease a 9×13-inch baking dish. Spread the cubed bread evenly across the bottom. Next, layer the cooked sausage over the bread. Sprinkle the shredded cheese on top.
Now, carefully pour the egg mixture over everything, ensuring it covers all the ingredients evenly. Press the bread down gently with a spoon to make sure it’s soaked in the egg mixture.
Overnight Option: Cover with foil and refrigerate overnight for an even easier morning bake.
Step 4: Bake to Perfection
Preheat your oven to 350°F (175°C). Bake the casserole uncovered for 45–50 minutes, or until the top is golden and a knife inserted in the center comes out clean.
If you notice the top browning too quickly, cover it loosely with foil during the last 15 minutes of baking.
Serving Suggestions
Let the casserole cool for 5–10 minutes before slicing. This helps it set up for cleaner servings.
Serve it alongside:
- Fresh fruit or a side salad for balance
- Hot sauce or salsa for a spicy kick
- Toast or biscuits for extra comfort
Garnish with chopped parsley or green onions for a touch of freshness and color.
Make-Ahead and Storage Tips
To Make Ahead:
Assemble the casserole the night before, cover with foil, and refrigerate. In the morning, bake as directed—no extra prep needed!
To Store Leftovers:
Store in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave or oven.
To Freeze:
Cool the baked casserole completely, then wrap tightly in foil and freeze for up to 2 months. Thaw overnight in the fridge and reheat in the oven at 350°F until warmed through.
Why It Works: The Science Behind the Layers
The bread acts as a sponge for the eggs and milk, giving the casserole a soft, custardy base. The sausage brings protein and bold, savory flavor. Cheese melts into every layer, creating richness that ties everything together. It’s a balance of textures and tastes that satisfies like no other breakfast.
