Ingredient Notes
- Pork sausage: Use bulk breakfast sausage for rich flavor; choose mild or hot to suit your taste.
- Eggs: Large, fresh eggs form the custard that binds the casserole.
- Milk: Whole milk gives a richer custard, but 2% works well too.
- Ground mustard: Adds brightness that lifts the cheese and sausage without a dominant mustard taste.
- Salt and black pepper: Season the custard to balance the richness of the other ingredients.
- Paprika: Provides mild warmth and a pleasant color.
- Nutmeg: A small dash deepens the custard’s flavor without being noticeable on its own.
- Bread: Italian or homemade bread works well; the cubes soak up the custard to give structure.
- Sharp cheddar cheese: Adds tang and melts nicely into the casserole.
How to Make It
- Brown the sausage in a skillet and drain well.
- Whisk eggs, milk, and seasonings in a large bowl until combined.
- Stir in the sausage, bread cubes, and shredded cheese.
- Transfer the mixture to a baking dish, cover, and refrigerate overnight.
- Bring the casserole to room temperature briefly before baking.
- Bake until the custard is set and the top is lightly golden.
Pro Tips
- Use day-old or slightly dried bread so it absorbs custard evenly without becoming soggy.
- Cut bread into uniform cubes for consistent texture throughout the casserole.
- Toast bread cubes lightly if you want extra nutty flavor and firmer structure.
- Let the casserole rest at room temperature for about 30 minutes before baking to promote even cooking.
- For a more browned top, remove the cover for the last 10–15 minutes of baking.
Recipe Variations
- Vegetarian version.
Omit the sausage and add sautéed mushrooms, onions, bell peppers, or spinach; the custard and cheese still hold everything together. - Different cheeses.
Try Monterey Jack, Swiss, Gruyère, or pepper jack for different flavors and melting qualities. - Turkey or chicken sausage.
Use poultry sausage for a lighter option; you may want to add extra seasoning since poultry sausages are often milder. - Add potatoes.
Fold in diced cooked potatoes or thawed hash browns for a heartier casserole. - Make it spicy.
Use hot sausage, red pepper flakes, or diced jalapeños for more heat.
Serving Suggestions
- Serve with a green salad of mixed greens and grape tomatoes to cut the richness with a fresh contrast.
- Add sliced avocado or guacamole for a creamy complement to the savory flavors.
- Pair with hash browns or home fries to add crisp, comforting potatoes to the meal.
- Offer pastries or breads—toast, muffins, croissants, or bagels—to round out a brunch spread.
- Serve with hot sauce or salsa for a bright, tangy, or spicy accent.
- Add fresh fruit like melon, berries, or sliced seasonal fruit to balance the warm, savory casserole with cooling sweetness.
How to Store
Refrigerate: Cool leftovers completely, then store in an airtight container for up to 4 days. Reheat portions in the microwave or oven.
Freeze: Wrap individual portions tightly or use a freezer-safe container for the entire casserole; freeze up to 2 months and thaw overnight before reheating.
Reheat: Warm slices in short microwave intervals or in the oven at low temperature; cover with foil to prevent drying.
Frequently Asked Questions
Yes. Baking immediately is fine, but the bread won’t have as much time to absorb the custard, so the texture will be slightly looser.
Absolutely. French bread, brioche, sourdough, sandwich bread, or even English muffins will work. Adjust quantities based on density and how well the bread soaks up the custard.
The center should be set and not jiggly. A knife inserted into the middle should come out clean.
Yes. Use a sturdy gluten-free bread so it doesn’t break down when soaked in the custard.
