- 1 lb Maple chicken sausage or maple beef sausage: For a rich and sweet flavor, these sausages provide the perfect base. You can also opt for turkey sausage for a leaner choice.
- 1 Medium sweet onion: Adds depth and sweetness to balance the savory elements.
- 6 cups Day-old sourdough bread: This creates a delightful texture and absorbs all the flavors beautifully.
- 2 cups Sharp cheddar cheese: Freshly shredded for optimal melting and flavor.
- 8 Large eggs: The heart of the dish, binding everything together.
- 2 cups Whole milk: Provides creaminess and richness.
- 2 tbsp Pure maple syrup: Enhances the maple flavor; feel free to drizzle extra on top before serving!
- 1 tsp Ground mustard: Adds a subtle kick; you can replace it with Dijon mustard for a different flavor profile.
- 1/2 tsp Fine sea salt: Essential for balancing flavors.
- 1/4 tsp Black pepper: For a hint of spice.
- 1/4 tsp Ground nutmeg: A warm spice that complements the sweetness of the dish.
Step-by-Step Instructions
Now that you have your ingredients ready, let’s get cooking!
- Heat a large skillet over medium heat. Add the maple chicken or beef sausage and the diced sweet onion. Cook, breaking the sausage apart with a wooden spoon, until browned and cooked through, about 8 to 10 minutes. Drain any excess fat.
- Grease a 9×13-inch baking dish. Place the sourdough bread cubes in an even layer at the bottom of the dish.
- Scatter the cooked sausage and onion mixture evenly over the bread cubes, then top with the shredded sharp cheddar cheese.
- In a medium bowl, whisk together the eggs, whole milk, pure maple syrup, ground mustard, sea salt, black pepper, and ground nutmeg until completely smooth and lightly frothy.
- Pour the egg mixture slowly and evenly over the bread, sausage, and cheese, pressing down gently with a spatula to ensure all the bread cubes are submerged. Cover the dish tightly with aluminum foil and refrigerate for at least 2 hours, or ideally overnight.
- Preheat your oven to 375°F (190°C). Bake the covered casserole for 35 minutes. Remove the foil and bake for an additional 10 to 15 minutes, until the top is golden-brown and puffy, and the center is completely set. Let stand for 10 minutes before slicing.
Pro Tips for a Perfect Bake

To ensure your casserole turns out perfectly every time, keep these expert insights in mind:
- Use stale bread: Day-old sourdough absorbs the egg mixture better, creating a moist casserole.
- Don’t skip the refrigeration: Allowing the casserole to sit overnight helps the flavors meld and ensures a custardy texture.
- Experiment with cheeses: While sharp cheddar is classic, feel free to mix in Gruyere or mozzarella for different flavor profiles.
- Try different sausages: For a unique twist, use spicy Italian sausage or even veggie sausage.
- Add veggies: Toss in diced bell peppers, spinach, or mushrooms for added nutrition and flavor.
- Check for doneness: The center should be set; a toothpick inserted should come out clean.
- Let it rest: Allowing the casserole to stand before slicing makes serving easier.
- Garnish before serving: Fresh herbs or green onions add a pop of color and freshness.
Common Mistakes and Troubleshooting
Even the best recipes can have hiccups. Here’s how to troubleshoot some common issues:
- Too dry: This can happen if the bread absorbs too much liquid. Ensure you use stale bread and don’t skip the egg mixture.
- Not enough flavor: Adjust the seasoning or consider adding a splash of hot sauce to the egg mixture for an extra kick.
- Overcooked edges: If the edges are browning too quickly, cover the dish with foil to prevent burning.
Variations to Try
Customization is key to keeping your meals exciting. Here are some variations to consider:
- Southwestern Style: Add black beans, corn, and diced jalapeños for a spicy twist.
- Vegetarian Delight: Substitute sausage with a mix of sautéed mushrooms and spinach for a hearty meatless option.
- Sweet and Savory: Incorporate diced apples or pears for added sweetness that complements the maple sausage.
- Herbed Casserole: Mix in fresh herbs like thyme or rosemary for an aromatic touch.
Storage and Make-Ahead Instructions
This casserole is perfect for meal prep, and it stores wonderfully!
- Refrigeration: Store leftovers in an airtight container in the fridge for up to 3 days.
- Freezing: For longer storage, freeze the casserole before baking. Wrap tightly in plastic wrap and foil, and it will keep for up to 2 months.
- Reheating: Bake frozen casserole directly from the freezer at 375°F (190°C) for about 60 minutes, or until heated through.
