Savory Sourdough Breakfast for Crowd
Ever wonder why some breakfast bakes have a soggy bottom but a burnt top? It usually comes down to how the bread handles the egg mixture. When you rush the process, the custard just sits on top instead of soaking through.
This recipe fixes that by using a long chill time. It's the ideal solution for any Breakfast for Crowd scenario because you do all the work the night before. You just slide it in the oven and go back to your coffee.
Looking for Breakfast for Crowd ideas that actually feed everyone? This sourdough bake handles a large group with minimal tools and zero morning stress.
Quick Recipe Specs
| Guests | Pan Size | Bake Temp | Doneness Cue |
|---|---|---|---|
| 12 People | 9x13 inch | 180°C (350°F) | Center reaches 74°C (165°F) |
Why This Method Works
- The Overnight Soak: Giving the bread 6 hours to drink the custard means the center cooks through without the edges drying out.
- Beef Sausage Base: Browning the meat first creates savory pockets of flavor and prevents the dish from becoming greasy.
- Sourdough Structure: The sturdy crumb of sourdough holds up under the liquid, so it doesn't turn into mush.
What You'll Need
| Component | Purpose | Substitute Notes |
|---|---|---|
| Sourdough Bread | Structural base | French bread works, but it's softer |
| Whole Milk | Creates custard | Heavy cream makes it richer |
| Beef Sausage | Savory protein | Turkey sausage is a leaner option |
| Sharp Cheddar | Binding and flavor | Gruyère adds a nuttier taste |
- 1 lb sourdough bread, cut into 1 inch cubes Why this? Holds its shape during the long soak
- 4 tbsp unsalted butter, melted
- 12 large eggs
- 2 cups whole milk
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 tsp garlic powder
- 1 tbsp Worcestershire sauce
- 1 lb ground beef sausage Why this? Adds deep, salty flavor
- 2 cups sharp cheddar cheese, shredded
- 1 cup green onions, thinly sliced
- 1 cup red bell pepper, finely diced
Essential Tools
Basic cookware is all that's required here. You'll just need a large mixing bowl, a sturdy whisk, a skillet to brown the sausage, and a 9x13 inch baking dish.
Step-by-step Instructions
Preparing the Components
Brown 1 lb ground beef sausage in a skillet over medium heat until fully cooked, then drain the excess fat. In a large bowl, whisk together 12 large eggs, 2 cups whole milk, 1 tsp kosher salt, 1/2 tsp black pepper, 1 tsp garlic powder, and 1 tbsp Worcestershire sauce until the mixture is completely smooth.
Layering the Casserole
Grease a 9x13 inch baking dish with butter. Toss 1 lb sourdough bread cubes with 4 tbsp melted butter and spread them evenly across the bottom of the baking dish. Scatter the cooked beef sausage, 1 cup diced red bell pepper, and 1 cup sliced green onions over the bread.
Sprinkle 2 cups shredded sharp cheddar cheese evenly across the top.
Pour the egg mixture slowly over the entire assembly. Press down slightly with a spatula to ensure the bread is fully submerged.
Baking to Perfection
Cover the dish with foil and refrigerate for at least 6 hours or overnight. Preheat the oven to 180°C (350°F). Bake covered with foil for 20 minutes.
Remove the foil and bake for another 20-25 minutes until the top is a deep mahogany colored brown and the center is set. Use a thermometer to ensure the center reaches an internal temperature of 74°C (165°F), as per USDA guidance for egg dishes.
Let the casserole rest for 10 minutes before slicing into 12 squares.
Fixing Common Issues
If the center stays too soft, it's usually because the bread cubes were too small or the oven temperature was off. Using a denser loaf and checking the internal temp is the only way to be sure it's done. If the top browns too quickly, just put the foil back on for the last 10 minutes.
Preventing Over-Browning
| Problem | Root Cause | Solution |
|---|---|---|
| Soggy middle | Underbaked or too much milk | Bake until center hits 74°C (165°F) |
| Burnt top | High oven heat | Cover with foil during final bake |
| Dry edges | Not enough soak time | Chill for a full 6 hours |
Tasty Flavor Swaps
This recipe is an excellent foundation for a large breakfast spread, so feel free to customize the mix-ins. For a lighter alternative, try a garden vegetable combination featuring spinach and feta.
If you are serving this at brunch, pairing it with something sweet like Healthy Pumpkin Bread creates a nice balance against the salty cheddar.
| Original Ingredient | Substitute | Why It Works |
|---|---|---|
| Sourdough | Challah | Sweeter, softer texture |
| Sharp Cheddar | Pepper Jack | Brings a zesty heat |
| Red Pepper | Diced Jalapeño | Replaces sweetness with spice |
Storage and Leftovers
Store leftover squares in a sealed container in the fridge. They stay fresh for up to 4 days. If you're prepping Breakfast for Crowd meals for the week, you can freeze individual slices wrapped in parchment paper and foil for up to 3 months.
To reheat, use the oven at 160°C (325°F) until the center reaches 74°C (165°F) on an instant-read thermometer. This keeps the edges from getting tough, which often happens in the microwave.
The Best Sides
I enjoy pairing this with a light arugula salad dressed in olive oil and lemon. The peppery greens provide a nice contrast to the rich, smooth egg custard. Sliced melon or a handful of fresh berries are also excellent choices for adding a fresh touch to the dish.
