Why This Casserole is a Weekday Warrior & Weekend Legend
Effortless Elegance: Four ingredients. One bowl. One dish. Maximum flavor.
Make-Ahead Magic: Assemble it the night before, refrigerate, and bake in the morning for a truly effortless meal.
Crowd-Pleasing Power: It’s universally loved, endlessly adaptable, and feeds a small army.
Perfect Texture: The bread soaks up the egg mixture, baking into a savory, unified custard with pockets of meat and cheese.
The Mighty Quartet: Your Breakfast Dream Team
1 lb Breakfast Sausage, cooked, crumbled, and drained
6 slices White Bread, cubed (about 4-5 cups)
2 cups Shredded Cheddar Cheese (or a Colby-Jack blend)
6 Large Eggs
(Salt & pepper are assumed staples!)
That’s the core. The blueprint for greatness.
The 5-Minute Prep, Overnight Wonder Method
Step 1: The Foundation
Grease an 8x11 or 9x13-inch baking dish. Spread the cubed bread evenly across the bottom.
Step 2: The Layers of Flavor
Sprinkle the cooked, crumbled sausage evenly over the bread. Follow with a generous layer of shredded cheese.
Step 3: The Custard Bath
In a medium bowl, whisk the eggs with ½ teaspoon salt and ¼ teaspoon black pepper until well beaten. Slowly and evenly pour the egg mixture over the entire casserole, ensuring every bit of bread gets moistened.
Step 4: The Patience (The Overnight Secret)
Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, preferably overnight (8-12 hours). This allows the bread to fully absorb the custard, guaranteeing a moist, cohesive bake.
Step 5: The Bake
When ready to bake, preheat oven to 350°F (175°C). Remove plastic wrap and bake the casserole, uncovered, for 40-50 minutes, until the top is puffed and golden brown, and the center is set.
Chef’s Notes for a Flawless Feast
Bread Choice: Stale bread works best! Day-old French bread, sourdough, or even croissants add fantastic texture and flavor.
Sausage Swap: Use cooked, crumbled bacon, diced ham, or even browned ground beef.
The “Unofficial” 5th Ingredient: For extra richness, whisk 1 ½ cups of milk or half-and-half into the eggs. This creates a more custard-like texture.
Vegetable Boost: Add ½ cup of sautéed diced onions, bell peppers, or spinach when layering with the sausage.
Make it Lighter: Use turkey sausage, reduced-fat cheese, and egg whites.
Serving Your Masterpiece of Simplicity
Let the casserole rest for 5-10 minutes before slicing. This helps it set for clean cuts.
Serve with:
A drizzle of hot sauce or salsa
A side of fresh fruit
A simple green salad
Leftovers reheat beautifully in the microwave or oven for easy breakfasts all week.
